# In a CBS News survey done in 2009, 95% of n=346 randomly sampled married men said that they would marry their spouse again if they had it to do all over again. In the same survey, 85% of n=522 married women said that they would marry their spouses if they had to do it over again. a. Calculate a 95% confidence interval that estimates the difference in proportions of married women and men who would marry their spouse again if they had it to do all over again. b. On the basis of the confidence interval determined in part a, can we infer that the population proporti

I need help on finding the height of a triangular pyramidif there’s no work, I don’t get credit

I will give Brainliest

20 in

Step-by-step explanation:

The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.

What can be the last digit of the fourth power of a natural number?

0, 1, 5 and 6.

Step-by-step explanation:

If we take all the digits  0 to 9 and take them to the power 4 we will get the answer.

eg 0^4 = 0 1^4 = 1 4^4 = 256

the answer is 0, 1,  5 and 6.

the last digit can only one of the following: 0, 1, 5, 6

Step by Step Explanations:

It is enough to show that all single digit numbers to the power on four end on one of the four above. Any number with two or more digits can be shown to have the same property.

Let me know if you have any questions.

A rectangular prism is 3 meters long, 4 meters wide, and has a total surface area of 94 square meters. What is its height?3 m
4 m
5 m
6 m

S = 2lw + 3lh + 2wh
94 = 2(3)(4) + 2(3)(h) + 2(4)(h)
94 = 2(12) + 2(3h) + 2(4h)
94 = 24 + 16h + 8h
94 = 24 + 14h
- 24  - 24
70 = 14h
14     14
5 = h
