Malik measured the middle school and made a scale drawing. He used the scale 8 inches = 6 feet. What is the scale factor of the drawing?

Answers

Therefore, the scale factor of the drawing is 4/3.

What is scale factor?

In mathematics, the scale factor is the ratio between two corresponding measurements in different scales. It is a measure of how much a figure or object has been scaled up or down, compared to its original size. The scale factor is often used in geometry and is particularly useful when creating scale drawings or models. A scale drawing is a drawing that is proportional to the actual size of the object it represents, but is scaled down or up by a certain factor to fit on a piece of paper or to make it easier to work with. The scale factor is used to determine the relationship between the measurements of the original object and the measurements of the scaled-down or scaled-up version.

Here,

To find the scale factor of the drawing, we need to determine the ratio of the length in the drawing to the actual length.

Here, the scale is given as 8 inches = 6 feet. This means that every 8 inches in the drawing represents 6 feet in real life.

To find the ratio of the length in the drawing to the actual length, we can set up a proportion:

8 inches / 6 feet = x inches / y feet

where x is the length in the drawing that corresponds to a length of y feet in real life.

To solve for x, we can cross-multiply and simplify:

8 inches * y feet = 6 feet * x inches

8y = 6x

x = (8/6) y

x = (4/3) y

This means that the length in the drawing is (4/3) times the length in real life.

what is the margin of error, using a 95% confidence level, for estimating the true population proportion of adult office workers who have worn a halloween costume to the office at least once? (round to the nearest thousandth)

Answers

For example, if the estimated population proportion of adult office workers who have worn a Halloween costume to the office at least once is 0.25 and the sample size is 400, the margin of error would be calculated as follows:

[tex]ME = 1.96*sqrt((0.25*(1-0.25))/400) = 0.032.[/tex]

The margin of error is 0.032. This means that if you were to survey a sample of adult office workers about the proportion of them who have worn a Halloween costume to the office at least once, the results of the survey would be within plus or minus 0.032 of the true population proportion 95% of the time.

A health expert evaluates the sleeping patterns of adults. Each week, she randomly selects 50 adults and calculates their average sleep time. Over many weeks, she finds that 5% of average sleep time is less than 9 hours and 5% of average sleep time is more than 9.4 hours.
What are the mean and standard deviation (in hours) of sleep time for the population?

Answers

The mean and standard deviation of sleep time for the population are 9.2 hours and 8.225 hours.

What does "normal distribution" mean?

In statistics and probability theory, the normal distribution is a continuous probability distribution that is often utilised. Due to its distinctive form, it is sometimes referred to as the bell curve or the Gaussian distribution. Many statistical and data analysis techniques, such as confidence intervals, regression analysis, and hypothesis testing, all make use of the normal distribution. It is well recognised that many real-world occurrences, like heights, weights, and IQ scores, follow a normal distribution, making it a useful tool for data analysis and interpretation.

Given that, 5% of average sleep time is less than 9 hours.

The z-score for the lower 5% percentile is z = -1.645.

Similarly, for upper 5th percentile we have z = 1.645.

The z-score is given as:

z = (x - μ) / σ

For the lower 5th percentile:

-1.645 = (9 - μ) / σ

For the upper 5th percentile:

1.645 = (9.4 - μ) / σ

Adding the two equations we have:

-1.645σ = (9 - μ)

1.645σ = (9.4 - μ)

0 = 18.4 - 2μ

μ = 9.2 hours.

Substitute the value of μ:

1.645σ = (9.4 - 9.2)

1.645σ = 0.2

σ = 8.225

Hence, the mean and standard deviation of sleep time for the population are 9.2 hours and 8.225 hours.

A system of two linear equations has no solution. The first equation is -7x + y = 3. select the second equation that will make this system have no solution.
A. 3x+y=3
B. -7x+y=-10
C. 3x+y=-7
D. 4x+y=3

Answers

Answer:

It's B.

Step-by-step explanation:

To make the given system of linear equations have no solution, we need the second equation to be inconsistent with the first equation. This means that the two equations must be parallel lines, and they cannot intersect at any point.

We can see that the first equation -7x + y = 3 has a slope of 7, since it can be written in slope-intercept form as y = 7x + 3. Therefore, to create a parallel line with the same slope of 7, we can choose the second equation to be:

B. -7x + y = -10

This equation has the same slope of 7 as the first equation, but it intersects the y-axis at a different point (-10 instead of 3). Therefore, the two lines are parallel and do not intersect, so the system of equations has no solution

The height, h, in feet of a ball suspended from a spring as a function of time, t, in seconds can be modeled by the equation h = 3 sine (StartFraction pi Over 2 EndFraction (t + 2)) + 5. Which of the following is the graph of this equation?

Answers

The graph of the equation, which looks like the below diagram.

What is the term graph means?

The term "graph" can refer to a visual representation of data or information, typically in the form of a diagram or chart. Graphs can be used to show relationships or patterns between different sets of data.

The given equation is:

h = 3 sin(π/2(t + 2)) + 5

This is a sinusoidal function with an amplitude of 3, a period of 4, a phase shift of -2, and a vertical shift of 5.

To graph this function, we can plot a few points and connect them with a smooth curve. For example, we can choose some values of t and calculate the corresponding values of h:

t = -4: h = 2

t = -3: h = 5

t = -2: h = 8

t = -1: h = 5

t = 0: h = 2

t = 1: h = -1

t = 2: h = 2

t = 3: h = 5

t = 4: h = 8

Using these values, we can sketch the graph of the function. The amplitude is 3, so the maximum height of the ball is 3 units above and below the vertical shift of 5. The period is 4 seconds, since the frequency is 2π/B = 4. The phase shift is to the left by 2 seconds. Therefore, the graph of the equation is as follows:

Complete question is:

The diagram shows a triangle.

Answers

Answer:

x = 11

Step-by-step explanation:

1) Put our angles into an equation

We know that all these angles in the triangle must add up to 180 so to put it simply we can write it as...

6x + x + 47 + x + 45 = 180

2) Simplify

To simplify what we have been given so far, we have to collect like terms.

8x + 92 = 180

3) Solve the equation

To solve this equation we have to isolate the x and to do this we have to get rid of the 92 and the 8. To get rid of these we have to subtract 92 from both sides and divide 8 from both sides!

8x + 92 - 92 = 8x = 888x ÷ 8x = x = 11

This means x = 11

Hope this helps, have a lovely day! :)

Answer:

See below.

Step-by-step explanation:

We are asked to find the value of x.

First, we should know that a Triangles' angles adds up to 180° due to the Triangle having 3 sides.

Since a Triangles' angles add up to 180°, we can set all of the angles' combined sum equal to 180°.

Our Equation:

[tex]6x+x+45+x+47=180[/tex]

We can begin solving for x.

Combine Like Terms:

[tex]8x+92=180[/tex]

Subtract 92 from both sides:

[tex]8x=88[/tex]

Divide by 8:

[tex]\frac{8x}{8} = \frac{88}{8} \\x = 11.[/tex]

Our final answer is x equals 11.

7. Allen believes 3 possible outcomes in a game are equally likely to occur.

Which conclusion BEST supports the data?

Answers

Since Allen believes that the 3 possible outcomes in the game are equally likely to occur, we would expect each outcome to occur with a frequency of approximately 1/3 or 33.3%.

Looking at the data, we see that outcome #2 occurred much more frequently than the other outcomes (14 times out of 20 total trials). This suggests that outcome #2 may not be equally likely to occur as the other outcomes.

Therefore, the best conclusion supported by the data is that Allen's assumption that the 3 outcomes are equally likely to occur may not be accurate.

Answers

D) g(x) is exponential; an exponential function increases faster than a linear function.

Determining exponential expression:

To determine which function is exponential, find the rate of change between the different years for each function.

An exponential function will have a constant rate of change over time, while a linear function will have a constant slope.

Looking at the table, we can calculate the rate of change between each year for both f(x) and g(x).

Here we have

x                   f(x)         g(x)

1995    69,682.50    72,429.27

2000   78,943.50   79,967.77

2006   90,056.70   90,056.70

2007    91,908.90   91,857.83

2010    97,465.50  97,480.27  

Calculate the rate increase the both cases

From f(x)  

For the years 1995 to 2000

=  [78,943.50 - 69,682.50 ]/ 69,682.50 x 100  = 13.3%

For the years 2000 to 2005

= [88,204.50 - 78943.50]/ 78943.50 × 100 = 11.73  

For g(x)

For the years 1995 to 2000

= [ 79,967.77 - 72,429.27]/ 72,429.27× 100 = 10.40  

For the years 2000 to 2005

= [ 88,290.88 - 79,967.77]/79,967.77  × 100 = 10.40  

Here we can observe that the rate of increase in g(x) is constant whereas in f(x) the rate of increase is decreasing

Hence we can conclude that

Solution:

$2,800 is invested in an account earning 2.8% interest (APR), compounded daily. Write a function showing the value of the account after tt years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.

Answers

Using the compound interest formula the percentage of growth per year (APY), to the nearest hundredth of a percent is 2.82%.

What is Compound Interest?

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

To calculate the value of the account after t years, we can use the formula for compound interest -

[tex]A = P(1 + \frac{r}{n} )^{(nt)}[/tex]

where -

A is the final amount

P is the principal amount

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the number of years

In this case, P = 2800, r = 0.028 (since the APR is 2.8%), n = 365 (since the interest is compounded daily), and we want to find A as a function of t.

So the function that represents the value of the account after t years is -

[tex]f(t) = 2800 \times \big(1 + \frac{0.028}{365} \big)^{(365 \times t)}[/tex]

We can simplify this function by using the fact that 0.028/365 is a constant.

Let's call this constant "k" -

k = 0.028/365

Then we can rewrite the function as -

[tex]f(t) = 2800 \times (1 + k)^{(365 \times t)}[/tex]

Rounding all coefficients to four decimal places, the final function is -

[tex]f(t) = 2800 \times (1 + 0.000077)^{(365 \times t)}[/tex]

To calculate the annual percentage yield (APY), we can use the formula -

[tex]APY = (1 + \frac{r}{n} )^{(n-1)}[/tex]

where r is the annual interest rate and n is the number of times the interest is compounded per year.

In this case, r = 0.028 and n = 365. So the APY is -

[tex]APY = (1 + 0.028/365)^{365 - 1} = 0.02824...[/tex]

Rounding to the nearest hundredth of a percent, the APY is 2.82%.

Therefore, the APY value is obtained as 2.82%.

For each part, do not round any intermediate computations and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas. (a) Find Austin's monthly payment. (b) If Austin pays the monthly payment each month for the full term, find his total amount to repay the loan. (c) If Austin pays the monthly payment each month for the full term, find the total amount of interest he will pay.

Answers

The required answers are a) P ≈ $441.59, b) $79,486.20, c) $23,486.20.

How to find monthly payment?

(a) To find Austin's monthly payment, we can use the formula for the monthly payment on an amortized loan:

P = (A * r) / (1 - (1 + r)^(-n))

where:

P = monthly payment

A = loan amount = $56,000

r = monthly interest rate = 5.25%/12 = 0.004375

n = total number of payments = 15 years * 12 months/year = 180

Plugging in these values, we get:

P = (56000 * 0.004375) / (1 - (1 + 0.004375)^(-180))

P ≈ $441.59

Therefore, Austin's monthly payment is $441.59.

(b) If Austin pays the monthly payment each month for the full term, he will make 180 payments. So his total amount to repay the loan is:

Total amount = Monthly payment * Number of payments

Total amount = $441.59 * 180

Total amount ≈ $79,486.20

Therefore, Austin will repay a total of $79,486.20 over the 15-year term.

(c) To find the total amount of interest Austin will pay, we can subtract the original loan amount from the total amount he will repay:

Total interest = Total amount - Loan amount

Total interest = $79,486.20 - $56,000

Total interest ≈ $23,486.20

Therefore, Austin will pay a total of approximately $23,486.20 in interest over the 15-year term.

The Belmont race track known as “Big Sandy” is 1½ miles long. In 1973, Secretariat won the Belmont Stakes race in 2 minutes and 30 seconds. Assuming he ran on “Big Sandy”, what was his unit speed?


im doing a test in class HELP ME! :______

Answers

In response to the query, we can state that Therefore on "Big Sandy," equation Secretariat's unit speed was roughly 0.05454 miles per hour.

What is equation?

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Secretariat's unit speed can be calculated using the following formula:

Unit speed = distance ÷ time

We are aware that Secretariat covered a distance of 112 miles, or 12 furlongs (1 furlong equals 1/8 mile). Also, we are aware of his timing, which was 2 minutes and 30 seconds, or 150 seconds.

Hence, after entering the values, we obtain:

Unit speed equals 150 seconds over 12 furlongs.

Unit speed = 0.08 furlongs per second

This needs to be multiplied by the conversion factor of 0.681818 to get miles per hour (mph):

Furlong speed equals 0.08 furlongs per second, or 0.681818 miles per hour.

Speed in miles per hour is 0.05454

Therefore on "Big Sandy," Secretariat's unit speed was roughly 0.05454 miles per hour.

What is the area of a trapezoid with base lengths 8 in and 10 in and a
height of 9 in?

Answers

Answer: 81 inches

Step-by-step explanation:

Area of a trapezoid is … Area= 1/2(b1+b2)h

So if we plug it in

Area = 1/2(8+10)9

= 1/2(18)9

= 9(9) = 81

Estimating Proportions The quality control people at your company have tested a sample of 450 widgets and found that 23 were defective. What is your interval estimate (confidence interval) for the average proportion of defective widgets (choose your confidence level)?

Answers

At a confidence level of 95%, the interval estimate for the average proportion of defective widgets is approximately 0.020 to 0.082.

To find the confidence interval for the proportion of defective widgets, we can use the formula:

CI = p ± z*(sqrt(p*(1-p)/n))

where:

p = proportion of defective widgets in the sample

z* = the z-value for the desired confidence level

n = sample size

The z-value depends on the desired confidence level. For example, if we want a 95% confidence level, we would use a z-value of 1.96 (from the standard normal distribution table).

Plugging in the values given in the problem, we get:

p = 23/450 = 0.0511

n = 450

z* = 1.96 (for a 95% confidence level)

sqrt(p*(1-p)/n) = sqrt(0.0511*(1-0.0511)/450) ≈ 0.016

Therefore, the 95% confidence interval for the proportion of defective widgets is:

CI = 0.0511 ± 1.96*0.016

= (0.020, 0.082)

This means we are 95% confident that the true proportion of defective widgets in the population is between 0.020 and 0.082.

Therefore , the solution of the given problem of triangle comes out to be  y + y√2 and y - y√2.  are the two possible numbers for x.

A triangle is exactly what?

If a polygon has at least one additional segment, it is a hexagon. Its form is a straightforward rectangle. Something like this can only be distinguished from a regular triangular by edges A and B. Euclidean geometry only creates a portion of the cube, despite the precise collinearity of the borders. A triangular has three sides and three angles.

Here,

Due to the similarity of the two triangles in the diagram, we can create an equation and solve for x using the ratios of respective sides.

Assuming that the line segment's length is x, we can construct the following equation:

=> (2x + y) / x = x / y

=> (2x + y) y = x²

=> 2xy + y² = x²

=> x² - 2xy - y² = 0

This quadratic equation in x has the coefficients a = 1, b = -2y, and c = -y2 in it. The quadratic algorithm yields:

=> x = [2y ± √((2y)² - 4(1)(-y²))] / 2(1)

=> x = [2y ± √(4y² + 4y²)] / 2

=> x = [y ± y√2]

Therefore, y + y√2 and y - y√2.  are the two possible numbers for x.

The two triangles in the illustration are thought to be comparable.

Answers

The average growth rate is 1.34%, which is calculated by the sum of the growth rates divided by the number of growth rates.



To calculate the average growth rate, we need to add up the given growth rates and then divide by the number of growth rates.

1. First, add up the given growth rates: 1.50% + 1.60% + .20% + .20% + 3.20% = 6.70%
2. Next, divide the sum by the number of growth rates: 6.70% / 5 = 1.34%
3. Finally, round the answer to 2 decimal places: 1.34%

On July 1, Mr Taylor owed $6,000. On the first of each of the following months he repaid $400.


a) list the amount owed by Mr. Taylor on the 2nd of each month starting with July 2


b) explain why the amount owed each month forms an arithmetic sequence

Answers

a) July 2- $5600, August 2- $5200, September 2- $4800, October 2- $4400, November 2- $4000

b) The amount owed each month forms an arithmetic sequence because it decreases by the same amount ($400) each month.

For the month of July, the amount owed is

6,000 - 400(1-1) = 6,000 - 400(0) = 6,000 - 0 = $6,000.

For the month of August, the amount owed is

6,000 - 400(2-1) = 6,000 - 400(1) = 6,000 - 400 = $5,600.

For the month of September, the amount owed is

6,000 - 400(3-1) = 6,000 - 400(2) = 6,000 - 800 = $5,200.

For the month of October, the amount owed is

6,000 - 400(4-1) = 6,000 - 400(3) = 6,000 - 1,200 = $4,800.

For the month of November, the amount owed is

6,000 - 400(5-1) = 6,000 - 400(4) = 6,000 - 1,600 = $4,400.

The amount owed by Mr. Taylor on the 2nd of each month starting with July 2 is as follows: July 2- $5600, August 2- $5200, September 2- $4800, October 2- $4400, November 2- $4000. This forms an arithmetic sequence because each month the amount owed decreases by the same amount of $400.Arithmetic sequences are collections of integers where each term following the first is created by adding a predetermined constant to the term before it. In this case, the constant is $400 because each month the amount owed is decreased by $400. An arithmetic sequence can be written as a mathematical expression, with the nth term being expressed as an + d(n-1). In the case of Mr. Taylor, the initial amount (a) is $6,000 and the common difference (d) is -$400 because the amount owed decreases each month. Therefore, each month the amount owed is expressed as 6,000 - 400(n-1).
