Intercept form

Answers

Answer:

y=2x-3

Step-by-step explanation:

Y-intercept can be read off the graph.

Slope can be determined using the formula:

y2-y1 divided by x2-x1 (Substitute co-ordinates)

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3

a. The area of the base is doubled.
b. The area of the base is quadrupled.
C. The area of the base is halved.
d. The area of the base is multiplied by one-fourth.​

Answers

Answer: In order to find the volume of a cylinder, you would use the formula V=3.14*r2*h. In the formula, the radius is being squared. That means that doubling the radius of the cylinder will quadruple the volume. For example, let's say we have a cylinder with a radius of 2 inches and height of 3 inches,

Answers

Answer: 64 minutes to put as many boxes as possible.
Explanation: The dimensions of Ellie's boxes in meters are: 0.45m by 0.40m by 0.35 ( to convert from centimeters to meters we just divide by 100, because 1m =100cm). therefore the volume of each box is 0.063 m3
Now the dimensions of the empty van are 3.6m by 1.6m by 2.1 m, therefore its volume is: 12.096 m3

So the amount of boxes that Ellie can put in the van is equal to the volume of the van divided by the volume of each box: 192 boxes

So 192 boxes can be put into the van.
Now Ellie can put 3 boxes in the van in 1 minute, therefore the amount of time it will take her to put 192 boxes into the van will be: 64 minutes

So it takes Ellie 64 minutes to put as many boxes into the van as she can.

Answers

Answer:

B

Step-by-step explanation:

There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.

For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.

Top left = (-3,4)

Bottom left = (-2, -4)

Top right = (3,4)

Bottom right = (1,-4)

The answer is B.

(-3,4) is the point/dot on the top left corner.

(3,4) is the point on the top right corner.

(1,-4) is the point on the bottom right corner.

(-2,-4) is the point on the bottom left corner.

Mark and his three friends ate out at Applebee's. (Hint* 4 total people) Their bill totaled $52.35. If they left the server a 20% tip, how much would each person pay splitting the bill evenly? (Round to the nearest dollar and cent)

Answers

Answer:

Unitary cost= $15.705

Step-by-step explanation:

Giving the following information:

Their bill totaled $52.35. They left the server a 20% tip.

First, we need to calculate the total cost of the meal:

Total cost= 52.35*1.2= $62.82

Now, we can split it into 4 equal parts:

Unitary cost= 62.82 / 4

Unitary cost= $15.705

Let y=f(x) be the particular solution to the differential equation dy/dx=2x−1/y^2 with the initial condition y(0)=3. Which of the following is an expression for f(x)?
A. √(x^2−x+9)

B. −3/3x^2−3x−1

C. (3x^2−3x)^1/3+3

D. (3x^2−3x+27)^1/3

Answers

Answer:

D. (3x^2-3x+27)^1/3

Step-by-step explanation:

dy/dx=2x−1/y^2

Cross multiply to get Y's and X's on different sides.

(y^2)dy = (2x-1)dx

Take the integral of each side

∫(y^2)dy = ∫(2x-1)dx

y^3/3 = 2x^2/2 - x + C

Multiply both sides by 3

y^3 = 3x^2 - 3x + C

Plug in (0,3) and solve for C

27 = 0 - 0 + C

C = 27

Plug in C to the equation

y^3 = 3x^2-3x+27

Cube root both sides to get just y

y = √(3x^2-3x+27)

y = (3x^2-3x+27)^1/3

D.

The particular solution of the equation will be "[tex](3x^2-3x+27)^\frac{1}{3}[/tex]".

Differential equation

According to the question,

→    [tex]\frac{dy}{dx}[/tex] = [tex]\frac{2x-1}{y^2}[/tex]

By applying cross-multiplication,

(y²)dy = (2x - 1)dx

By integrating both sides, we get

→ ∫(y²) dy = ∫(2x - 1) dx

           [tex]\frac{y^3}{3}[/tex] = [tex]\frac{2x^2}{2}[/tex] - x + C

By multiplying "3" both sides, we get

           y³ = 3x² - 3x + c

By substituting "(0,3)" in above equation,

          27 = 0 - 0 + C

            C = 27

By substituting value of C in the above equation,

         y³ = 3x² - 3x + 27

By cubing both sides,

y = √(3x²-3x+27)

  = [tex](3x^2-3x+27)^\frac{1}{3}[/tex]        

Thus the above answer i.e., "Option D" is correct.

2. By definition, jumbo shrimp are those that require between 10 and 15 shrimp to make a pound. Suppose that the number of jumbo shrimp in a 1-pound bag averages μ = 12.5 with a standard deviation of σ = 1.5, and forms a normal distribution. What is the probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag?

Answers

Answer:

0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Single bag:

[tex]\mu = 12.5, \sigma = 1.5[/tex]

Sample of 25 bags:

[tex]n = 25, s = \frac{1.5}{\sqrt{25}} = 0.3[/tex]

What is the probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag?

This is 1 subtracted by the pvalue of Z when X = 13. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{13 - 12.5}{0.3}[/tex]

[tex]Z = 1.67[/tex]

[tex]Z = 1.67[/tex] has a pvalue of 0.9525

1 - 0.9525 = 0.0475

0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.

Answers

Answer:

t= 9.49 years which can be estimated to 9 years

Step-by-step explanation:

Given the formula l = prt,

Where P is the principal=$245

r is the interest rate.=3%,

l = interest earned=$69.80

l = prt

Therefore time, t= I/ pr

t= 69.80/ 245 x 3%

t=69.80/ 245 x 0.03

t= 9.49 years which can be estimated to 9 years
