2. Solve 92n = 404n-7. Round to the nearest ten-thousandth, which is four places after the decimal
point.

Answers

Answer:

n = 0.0224

Step-by-step explanation:

The given expression is :

92n = 404n-7

We need to solve it for n.

Subtract 92n from both sides,

92n-92n = 404n-7-92n

7 = 404n-92n

7 = 312 n

n = 0.0224

So, the value of n is equal to 0.0224.

A class consists of 23 women and 83 mean. If a student is random selected, what is the probability that the student is a woman?

Answers

Answer:

[tex]P(Woman) = \frac{23}{106}[/tex]

Step-by-step explanation:

Given

[tex]Women = 23[/tex]

[tex]Men = 83[/tex]

Required

[tex]P(Woman)[/tex]

This is calculated as the number of women divided by the population of the class

i.e.

[tex]P(Woman) = \frac{Women}{Women + Men}[/tex]

So, we have:

[tex]P(Woman) = \frac{23}{23+83}[/tex]

[tex]P(Woman) = \frac{23}{106}[/tex]

The mean area of homes in a certain city built in 2009 was 2438 square feet. Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet. An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009. Compute the P-value of the test. Write down your P-value. You will need it for the next question.

Answers

Answer:

The p-value of the test is 0.029.

Step-by-step explanation:

The mean area of homes in a certain city built in 2009 was 2438 square feet.

An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.

This means that at the null hypothesis we test if the mean is the same as in 2009, that is:

[tex]H_0: \mu = 2438[/tex]

At the alternate hypothesis, we test that if it is less, than is;

[tex]H_a: \mu < 2438[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

2438 is tested at the null hypothesis:

This means that [tex]\mu = 2438[/tex]

Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet.

This means that [tex]n = 11, X = 2293, s = 225[/tex]

Value of the test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{2293 - 2438}{\frac{225}{\sqrt{11}}}[/tex]

[tex]t = -2.14[/tex]

Compute the P-value of the test.

Probability of finding a mean less than a value(in this case, 2293) is a one-tailed test.

The pvalue is found for a one-tailed test, with t = -2.14 and 11 - 1 = 10 degrees of freedom. With the help of a calculator, the pvalue of the test is of 0.029

The p-value of the test is 0.029.

Step-by-step explanation:

So, the small red circles are the baskets.

Each 1 represents 1 basket.

We know that the two baskets on 4 wont be counted, as well as the two baskets on 4 1/2, since thats smaller than or equal to 4 1/2

We also know that the two baskets on 6 wont be counted either, since thats equal to 6.

So now lets count the baskets in between these values, which would be:

5 - 4 baskets

5 1/2 - 4 baskets

Lets add those up:

4+4

Which images are tessellations?


Image 1 and 4
Image 3 and 2
Image 1 only
Image 3 and 4

Answers

Image 3 and 4, because they fit perfectly

Option - D - Image 3and 4 is correct

We have the following images.

We have to classify which image is a tessellations.

What are tessellations?

tessellations is also called tiling which involves the covering up of rigid plane surface using the geometric shapes (tiles) ensuring that these shapes don't overlap and leave no gap.

In the image 3, we have a geometric shape called triangle which is used as a tile to cover the surface. These shapes don't overlap and leave no gap as they perfectly fit with one another. Similar is the case with image 4, where hexagonal tiles are used. Therefore, image 3 and 4 are tessellations. The images 1 and 2 does not have any predefined geometric shape and nothing can be said about their perfect fit. Hence these are not tessellations.

Hence, Option - D is correct.

1. 28

Explanation:
1. For perimeter you add all the side lengths together, and since in parallelogram both pair of opposite sides are parallel, so your equation would be: 4+4+10+10=28
3. Area=base x height, the base=10 and the height it the length of the line inside the parallelogram which equals 3. So, but the numbers into area formula: Area=10x3
Solve: Area=30
4. Do the same as the first problem add all the side lengths: 11+4+4+7=26

Find the measure of each numbered angle or are.

Answers

Answer:

<1 = 138degrees

<2 = 156degrees

Step-by-step explanation:

From the diagram given;

angle at the vertex = 36degrees

Angle at the intercepted arc are <1 and 66degrees

Using the theorem;

Angle at the vertex is 1/2 the difference of the angles at the intercepted arcs

36 = 1/2(<1-66)

36*2 = <1-66

72 = <1 - 66

<1 = 72+66

<1 = 138degrees

Also since the sum of angle in a circle is 360degrees, hence;

<1 + <2 + 66 = 360

138 + <2 + 66 = 360

<2 + 204 = 360

<2 = 360 - 204

<2 = 156degrees
