Answer: That would be 1 case + 112 pack + 16 pack + 5 singles
Step-by-step explanation:
Answer:
0.0062
Step-by-step explanation:
Find the standard error.
σ = 20 / √100
σ = 2
Find the z-score.
z = (x − μ) / σ
z = (70 − 65) / 2
z = 2.5
Find the probability.
P(Z > 2.5) = 1 − 0.9938
P(Z > 2.5) = 0.0062
Ln20+ln5=2ln x
ln(20*5) = ln x^2
ln 100 = ln x^2
100 = x^2
x = 10 second option
(3/500)*(12,000) = 72 batteries . . . answer is B) 72
The area of a circle is r^2*PI -> d = 10inch -> r = 5inch --> r^2 * PI = 5 * 5 * 3.14159 = 78.54 in^2
