Create two equivalent fractons for 3/4

Answers

Answer:

6/8 and 9/12

Step-by-step explanation:

You can find any by multiplying numerator and denominator by any given number. The number multiplied has to be the same for the top and the bottom

1. Number is 2

3/4 * 2/2 = 6/8 (3*2 = 6 and 4*2 = 8)

2. Number is 3

3/4*3/3 = 9/12 (3*3 = 9 and 3*4 = 12)

A company has a new process for manufacturing large artificial sapphires. In a trial run, 37 sapphires are produced. The mean weight for these 37 gems is 6.75 carats, and the sample standard deviation is 0.33 carat. Obtain a 95% confidence interval for the true mean weight of all sapphires produced by the new process. Interpret your results in the context of the problem. State the margin of er

Answers

Answer:

The margin of error is of 0.11 carats.

The 95% confidence interval for the true mean weight of all sapphires produced by the new process is between 6.64 and 6.86 carats. The interpretation is that we are 95% sure that the true weight of all sapphires produced by the company using the new process is between these two values.

Step-by-step explanation:

We have the standard deviation for the sample, which means that we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 37 - 1 = 36

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 36 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.05}{2} = 0.975[/tex]. So we have T = 2.0281

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.0281\frac{0.33}{\sqrt{37}} = 0.11[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The margin of error is of 0.11 carats.

The lower end of the interval is the sample mean subtracted by M. So it is 6.75 - 0.11 = 6.64 carats

The upper end of the interval is the sample mean added to M. So it is 6.75 + 0.11 = 6.86 carats.

The shed that Vicky and Jim will use is the second shed (length | 4 [] width | 2 1/4), because the height length is 7.

4 x 2.25 = 9

63 divided by 9 = 7

(First Shed) 5 x 2.20 = 11

66 divided by 11 = 6

7 > 6

7 = Height of First Shed

The first shed will be used to store the new lawnmower since it is the taller shed.

2. [5pts] The Pew Research Group conducted a poll in which they asked, "Are you in favor of, or opposed to, executing persons as a general policy when the crime committed while under the age of 18?" Of the 580 Catholics surveyed, 180 indicated they favored capital punishment; of the 600 seculars surveyed, 238 favored capital punishment. Is there a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18? Use the ???? = 0.01 level of significance. Show all work.

Answers

Answer:

See below for answers and explanations

Step-by-step explanation:

Here, we are comparing two proportions of a large sample size. Therefore, conducting a 2-proportion z-test is appropriate. Conditions are already assumed, so we can conduct the test.

We are testing our null and alternate hypotheses which are:

H: p1=p2 (there is no difference)

Ha: p1≠p2 (there is a difference)

Given:

x1=180

n1=580

x2=238

n2=600

p1=180/580=0.31

p2=238/600=0.4

p=(180+238)/(580+600)=418/1180=0.35

Use the formula to calculate the z-statistic:

[tex]Z=\frac{p_1-p_2}{\sqrt{p(1-p)(\frac{1}{n_1}+\frac{1}{n_2})}}[/tex]

[tex]Z=\frac{0.31-0.4}{\sqrt{0.35(1-0.35)(\frac{1}{580}+\frac{1}{600})}}[/tex]

[tex]Z=-3.24[/tex]

Calculate p-value (note that this is two-sided):

1) normalcdf(-1e99,-3.24)=5.977105194*10^-4

2) Since this is a two-sided test, we double it to get p=0.001195421

Conclusion: Since 0.0012<0.05, we reject the null hypothesis and conclude that there is a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18 because our p-value is extremely low.

In the diagram, KLMN is a rectangle, and the two shaded regions are squares. If the length of KL is 6 centimeters, and the length of KN is 14 centimeters, which is closest to the length of ST in centimeters?

Answers

Answer:

15.2cm

Step-by-step explanation:

From the given diagram;

KN = SN = 14cm

KL = NT = 6cm

Required

Using the Pythagoras theorem;

ST² = SN² + NT²

ST² = 14² + 6²

ST² = 196 + 36

ST² = 232

ST = √232

ST = 15.2cm

Hence the length of ST is 15.2cm
