The mean for the math component of the New Century Achievement Test is reported as 100, with a standard deviation (σ) of 15. A sample of 400 students throughout a particular school district reveals a mean (Symbol) score of 110. Estimate the mean score for all the students in the district, using a 99% confidence interval.

Answers

Answer: To estimate the mean score for all the students in the district, we can use a confidence interval. We are given that the sample size is 400, the sample mean is 110, the population means is 100, and the population standard deviation is 15. We are asked to find a 99% confidence interval for the population mean.

The formula for a confidence interval for the population mean with known population standard deviation is:

Confidence interval = sample mean ± z*(σ/√n)

where:

sample mean = 110 (given)

σ = 15 (given)

n = 400 (given)

z = the critical value from the standard normal distribution for a 99% confidence level, which is 2.576.

Substituting the values, we get:

Confidence interval = 110 ± 2.576*(15/√400)

Confidence interval = 110 ± 1.92

Therefore, the 99% confidence interval for the population mean score is (110 - 1.92, 110 + 1.92), or (108.08, 111.92). We can be 99% confident that the true population mean score for all the students in the district falls between 108.08 and 111.92.

If I write 3 to the left of my number, and double this three digit number, the result is 27 times my original number What is my original number?​

Answers

Answer:

Step-by-step explanation:

Let the age of the son be $s$ and the age of the father be $f$. From the first equation, we have $2s + f = 56$, and from the second equation, we have $f + 2s = 82$. Solving this system of equations, we get $s = 12$ and $f = 32$, so the son is 12 years old and the father is 32 years old.

Let the two-digit number be $10t+u$, where $t$ is the tens digit and $u$ is the units digit. We are given that $t+u=13$ and $2t-u=1$. Solving this system of equations, we get $t=7$ and $u=6$, so the two-digit number is $76$.

Let the two-digit number be $10x+y$, where $x$ is the tens digit and $y$ is the units digit. We are given that $2(10+x+y) = 27(10x+y)$, or $20+2x+2y = 270x+27y$. Simplifying this equation, we get $268x-25y = 10$. Since $y$ is a digit, we know that $0 \leq y \leq 9$. We can check that $x=1$ is too small, so we try $x=2$. Plugging in $x=2$, we get $536-25y=10$, which gives $y=21/5$, which is not a digit. Thus, there is no solution for a two-digit number.

What is the experimental P(B)

Answers

The experimental probability of rolling a number less than or equal to 4 is 0.7.

How is conditional probability calculated? What does it mean?

The likelihood that an event (A) will occur given the occurrence of another event (B) is known as conditional probability. P(A|B), which stands for "the probability of A given B," is used to express it. You must first determine P(A and B) by multiplying the odds of A and B happening together. Next, you may compute P(A|B). The conditional probability of A given B is then obtained by dividing the result by P(B).

Several situations in everyday life, including medical diagnosis, industrial quality control, and risk assessment in insurance, call for the usage of conditional probability.

Given that, the trial was run 10 times.

Thus,

P(B) = (number of times B occurred) / (total number of trials)

= 7 / 10

= 0.7

Therefore, the experimental probability of rolling a number less than or equal to 4 is 0.7.

What is the base of a parallelogram with an area of 36 units2 and a height of 9 units?

Answers

The base length of the parallelogram found using the area formula is 4 units.

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size. A parallelogram has adjacent angles that add up to 180 degrees. 360 degrees is the sum of all interior angles.

A parallelogram's area is the area that it takes up in a two-dimensional plane. The parallelogram's area is calculated by multiplying the base length by the height.

Each shape's perimeter can be defined as either the entire length or total distance encircling the object. The entire distance between a parallelogram's boundaries is also known as the parallelogram's perimeter.

Given,

The area of the parallelogram A =36 sq. units

The height of the parallelogram  h = 9 units

We are asked to find the base length b.

Now the formula for the area of the parallelogram is:

HELP ASAP pls!!!

Answers

Answer:

The simplified expression is -13/12.  (are you sure you don't have a typo somewhere), double checked.

Step-by-step explanation:

First, let's simplify the expression inside the absolute value bars:

5/6 - 17/12 = 10/12 - 17/12 = -7/12

Next, we can simplify the expression outside the absolute value bars:

| -7/12 | - | 5/3 |

= 7/12 - 5/3 (since the absolute value of -7/12 is 7/12)

= 7/12 - 20/12

= -13/12

The simplified expression is -13/12.

_______________________

Simplify the following:

abs(5/6 - 17/12) - abs(5/3)

Put 5/6 - 17/12 over the common denominator 12. 5/6 - 17/12 = (2×5)/12 - 17/12:

abs(((2×5)/12 - 17/12)) - abs(5/3)

2×5 = 10:

abs(10/12 - 17/12) - abs(5/3)

10/12 - 17/12 = (10 - 17)/12:

abs(((10 - 17)/12)) - abs(5/3)

10 - 17 = -7:

abs((-7)/12) - abs(5/3)

Since 5/3 is a non-negative constant, abs(5/3) = 5/3:

abs(-7/12) - 5/3

Since -7/12 is a negative constant, abs(-7/12) = 7/12:

7/12 - 5/3

Put 7/12 - 5/3 over the common denominator 12. 7/12 - 5/3 = 7/12 + (4 (-5))/12:

7/12 - (5×4)/12

4 (-5) = -20:

7/12 + (-20)/12

7/12 - 20/12 = (7 - 20)/12:

Triangle RST was dilated by a scale factor of 5 to create triangle LMN. (Show your work)

If tan R = 5/2.5 find the measure of segments LM and MN.

Answers

Therefore , the solution of the given problem of triangle  comes out to be segments LM and MN have equal 10x measures.

What exactly is a triangle?

A triangle is a polygon because it has two or more additional parts. It has the simple form of a rectangle. A triangle can only be distinguished from a conventional triangle by its three sides, A, B, but not C. So when borders are still not exactly collinear, Euclidean geometry results in a single area as opposed to a cube. Three edges and three angles are the characteristics of triangles.

Here,

Given that RS and LM are the respective sides of the two triangles, if we set x as the length of RS, then LM's length is 5x and ST's length is 2x. The duration of MN is five times that of ST, which is ten times longer.

We can now calculate the length of RS using the tangent of angle R:

=> tan R=RS/ST

=> 5/2.5=2

We thus have:

=> RS = 2

=> ST = 2x

We can determine the length of RT using the Pythagorean theorem:

=> RT/ST = sin R

=> RT = ST sin R

=>  2.5 (2/29) = 4.337 sin R = 2.5

We can now determine the lengths of LM and MN using the similarity of the triangles:

=> RM = 5 (2x) LM = 5 = 10

=> MN = 5 ST = 5 (two times) = 10

As a result, segments LM and MN have equal 10x measures.

Define the term triangle?

A triangle is a closed geometric figure consisting of three line segments or sides, connected to each other at three endpoints or vertices. Each side of a triangle intersects with exactly two other sides, and the vertices are the points where the sides meet.

From the given figures, both the triangles are right angle triangle.

[tex]tan R=\frac{5}{2.5} = \frac{ST}{RS}[/tex]

So, ST = 5 and RS = 2.5

Since, ΔRST is 5th to create ΔLMN,

its corresponding sides are 5 times the length LM corresponding sides of RS. So, its length

LM = 5×2.5 = 12.5

LM = 12.5

MN corresponding sides of ST. So, its length

MN = 5×5 = 25

MN = 25

Therefore, The values of LM = 12.5 and MN = 25.

A rancher has 600
feet of fencing to put around a rectangular field and then subdivide the field into 3
identical smaller rectangular plots by placing two fences parallel to one of the field's shorter sides. Find the dimensions that maximize the enclosed area. Write your answers as fractions reduced to lowest terms.

Answers

The dimensions of the rectangular field that maximize the enclosed area are 150 feet by 75 feet.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

Let's call the length of the rectangle "l" and the width "w".

We can write two equations based on the given information -

Perimeter equation: 2l + 4w = 600 (since there are two sets of parallel sides, we have to add an extra "w" to the perimeter equation)

Area equation: A = 3lw (since the field is divided into 3 equal parts)

We want to maximize the enclosed area, which means we want to find the values of "l" and "w" that make the area as large as possible.

We can use the perimeter equation to solve for one of the variables in terms of the other -

2l + 4w = 600

2l = 600 - 4w

l = 300 - 2w

Now we can substitute this expression for "l" into the area equation -

A = 3lw

A = 3(300 - 2w)w

A = 900w - 6w²

To find the maximum area, we can take the derivative of this equation with respect to "w" and set it equal to zero -

dA/dw = 900 - 12w = 0

12w = 900

w = 75

So the width of each of the smaller rectangular plots is 75 feet.

We can use the perimeter equation to find the length -

2l + 4w = 600

2l + 4(75) = 600

2l = 300

l = 150

Therefore, the dimensions value are obtained as 150 feet by 75 feet.

g: Z → Z, where g(x) = |x|^2.

Yes, these functions are equal, this happens because both outcomes will always be positive, indifeterent of the absolute value part.

b)   f: Z × Z → Z, where f(x,y) = |x + y|.

g: Z × Z → Z, where g(x,y) = |x| +| y|.

These are different, if x = 1 and y = -1

f(1, - 1) = |1 - 1| = 0

g(1, -1) = |1| + |-1| = 2

c) B = {0, 1}

f: B × B → B × B, where f(x,y) = (1-y, 1-x)

g: B × B → B × B, where g(x,y) = (x,y)

This is clearly false, when x and y are 0 and 0 we have:

f(0, 0) = (1 - 0, 1 - 0) = (1, 1)

While g gives:

g(0, 0) = (0, 0)

These functions are different.

Four components of 55

Answers

Answer: 1, 5, 11, 55

Step-by-step explanation:

An alloy is made up of 93.5 parts aluminum, 5 parts zinc, and 1.5 parts copper. A foundry
has 164 pounds of aluminum available. Find the weight of the zinc and copper that will be
needed to make the alloy.

Answers

Answer: Since the alloy is made up of 93.5 parts aluminum, 5 parts zinc, and 1.5 parts copper, we can express the weight of zinc and copper needed to make the alloy as a ratio to the weight of aluminum needed. Let x be the weight of aluminum needed in pounds, then we have:

Weight of aluminum: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

We know that the foundry has 164 pounds of aluminum available, so we can substitute x = 164 into the above ratio and solve for the weights of zinc and copper:

164: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

Cross-multiplying, we get:

164 × 5 = 93.5 × Weight of zinc

Weight of zinc = (164 × 5) / 93.5

Weight of zinc = 8.76 pounds (rounded to two decimal places)

Similarly, cross-multiplying the above ratio gives us:

164: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

164 × 1.5 = 93.5 × Weight of copper

Weight of copper = (164 × 1.5) / 93.5

Weight of copper = 2.63 pounds (rounded to two decimal places)

Therefore, the weight of zinc needed to make the alloy is 8.76 pounds and the weight of copper needed is 2.63 pounds.

the distance between (-7, 3) and (5, 3)

Answers

Answer:

12

Step-by-step explanation:

7+5

Answer:

.

Step-by-step explanation:

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Here, (x1, y1) = (-7, 3) and (x2, y2) = (5, 3).

Substituting these values, we get:

d = sqrt((5 - (-7))^2 + (3 - 3)^2)

= sqrt((12)^2 + (0)^2)

= sqrt(144)

= 12

Therefore, the distance between (-7, 3) and (5, 3) is 12 units.
