A random variable Z is normally distributed with mean 0 and standard deviation 1. It is known that P(z<-1.6)=a and P(z>2.4)=b. This is shown in the following diagram. A. find P(-1.6 B. given that z>-1.6, find the probability that z<2.4. Write your answer in terms of a and b.

k = 2

Step-by-step explanation:

Given:

2 + 2k = 6

Find k

2 + 2k = 6

Subtract 2 from both sides of the equation

2 + 2k - 2 = 6 - 2

2k = 4

Divide both sides by 2

2k/2 = 4/2

k = 2

Check

2 + 2k = 6

2 + 2(2) = 6

2 + 4 = 6

6 = 6

step-by-step explanation:

compare

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
