Answer:
The ages of people entering a pie eating contest are normally distributed with a mean of 35 years and a standard deviation of 8.2 years.
What is the age of a pie eating contestant with a z-score of −2.1 ?
[ Age - 35 ] / [ 8.2] = -2.1 multiply both sides by 8.2
Age - 35 = -17.22 add 35 to both sides
Age ≈ 17.8 years
I am doing the test right now !!! ;P
Given:
L = W - 4
P = 2L + 2W
We can substitute 2L for 2(W - 4) = 2W - 8
So:
2W - 8 + 2W = P
P = 4W - 8
Answer is 4. 4W-8
Y = kxz
Find k first to get the equation.
206 = k*(6*11)
206 = 66*k
Divide both sides by 66.
3.12 = k
y = 3.12xz
y = 3.12(-4*25)
y = 3.12(-100)
y = -312
Well what do you need help with? Elaborate(specify) what you need help on. We can't help you if we don't know what to help you on.
Answer:
The answer would be 0.0016
Step-by-step explanation:
When putting a number to a power you multiply it that many times it's self.
0.2*0.2=0.04, 0.2*0.2=0.04
0.04*0.04=0.0016.
