Answer:
The answer for this problem is
C) y = -x + 6
Step-by-step explanation:
I know this because I just did the test
Slope formula : y2 - y1 / x2 - x1
( 34 , 12 ) and ( 32 , 48 )
48 - 12 / 32 - 34
36 / - 2
slope = - 18
Answer: Our required probability is 0.167.
Step-by-step explanation:
Since we have given that
n = 15
Probability of success p = 80% = 0.8
Probability of failure q = 20% = 0.2
We need to find the probability that at least fourteen will work.
So, by Binomial distribution, we get that

Hence, our required probability is 0.167.
Answer:
Variance = 73.96 
Step-by-step explanation:
We are given that standard deviation is 8.6 kg.
Now, Variance formula =
=
= 73.96
