Only the top one is equivalent to c/(13a)

The rule is (a^b)/(a^c)=a^(b-c)

What is the answer to the question<br> 1.5(q-4)-2=4<br> Thank you so much for answering!

Ghella [55]

Answer:

q= 8

Step-by-step explanation:

1.5q-6-2=4

1.5q-8=4

1.5q=4+8

1.5q+4+8= 12

divide both sides

1.5q=12=8

Answer:

14. 2384 in²

15. 291.8 in²

Step-by-step explanation:

14. The total surface area consists of the area of two equal triangles and three rectangles.

The area of each triangle is $\frac{1}{2} bh$ , which is $\frac{1}{2}(24)(14)=168 in²$ . The area of both triangles combined is 336 in².

The area of each of the slanted rectangles is base x height, which is 25x32=800 in². The area of both rectangles combined is 1600 in².

The area of the base rectangle is 14x32=448 in².

Therefore, to find the total surface area, you add the area of each side together: 336+1600+448=2384 in².

15. The equation for the surface area of a cylinder is $2\pi r^{2} +2\pi rh$ .

The radius (r) is 4.6 in and the height (h) is 9.1 in.

Therefore, the surface area is:

$2\pi (4.6)+2\pi (4.6)(9.1)=28.888+262.88=291.8\\$ in²

Brrunno [24]

Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

EU (European Union) countries report that 46% of their labor force is female. The United Nations wants to determine if the percentage of females in the U.S. labor force is the same. Based on a sample of 500 employment records, representatives from the United States Department of Labor found that the 95% confidence interval for the proportion of females in the U.S. labor force is 0.357 to 0.443. If the Department of Labor wishes to tighten its interval, they should:

A. increase the confidence level

B. decrease the sample size

C. increase the sample size

D. Both A and B

E. Both A and C

Solution:

Confidence interval for population proportion is written as

Sample proportion ± margin of error

Where sample proportion is the point estimate for the population proportion.

Margin of error = z × √pq/n

The z score for 95% confidence level is 1.96

p = 46/100 = 0.46

q = 1 - p = 1 - 0.46

q = 0.54

n = 500

Margin of error = 1.96√0.46 × 0.54/500 = 0.044

To tighten it's interval, the margin of error needs to be reduced.

If we increase the confidence level, say to 99%, z = 2.58

Then

Margin of error = 2.58√0.46 × 0.54/500 = 0.058

It increased

Also, If we increase the sample size, say to 700, then

Margin of error = 1.96√0.46 × 0.54/700 = 0.037

It has reduced

Therefore, the correct options is

C. increase the sample size
