Vol of prism = area of base * height
= 214*8* 2012 = 3444544 cubic cm

How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.

WILL GIVE BRAINLIEST<br>What is the value of a in the problem 4a-3=D<br>explain answer

mixas84 [53]

In this case, you aren't going to get an integer for the value of a, but you can rearrange the equation to equal a.

4a-3=D   add 3 to both sides
4a=D+3    divide both sides by 4
a=(D+3)/4   here's your answer

Convert 17⁄8 to a decimal, rounded to the nearest hundredth. A. 2.13 B. 2.44 C. 1.78 D. 1.14

Hey there! :)

All you have to do is divide the numerator(top number) by the denominator(bottom number).

17 ÷ 8 = 2.125

Rounded to the nearest hundredth = 2 places after the decimal point.

After the 2 is a 5. If it's 5 or greater, you move it up by 1.

2 + 1 = 3

2.125 = 2.13

Your answer is A ⇒ 2.13

Hope this helps :)

You are to take a multiple-choice exam consisting of 64 questions with 5 possible responses to each question. Suppose that you h

Answer:

a) Expected score on the exam is 12.8.

b) Variance 10.24, Standard deviation 3.2

Step-by-step explanation:

For each question, there are only two possible outcomes. Either you guesses the answer correctly, or you does not. The probability of guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$
