Answer: 500
Step-by-step explanation:
502.564102564 rounded is 500
V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
Answer:
0.98732
Step-by-step explanation:
Given that :
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 * 10 = 400 minutes
Variance = 2 * 40 = 80 minutes
Standard deviation (s) = √variance = √80
Converting hours to minutes
X = 60 * 7 = 420 minutes
P(X≤ 420) :
Z = (x - m) / s
P(X≤ 420) :
Z = (420 - 400) / √80
Z = 20 / √80 = 20 / 8.9442 = 2.236
P(Z ≤ 2.236) = 0.98732
Answer:
6(x-10)=5-2(1-x)
Step-by-step explanation:
I divided by 3 the parenthesis, and multiplied by 3 the first number, which makes an equivalent equation.
