20 because radius times height will give you the surface area of the shape
We have the mean, μ = 20 and the standard deviation, σ = 4
X ≈ N(20, 4²)
We want P(X<15)
Standardising gives
P(X<15) = P(Z<
)
P(X<15) = P(Z< -1.25) ⇒ When the value of the z-score is negative, we will read the value of z<1.25 on the z-table then subtract the answer from 1
P(X<15) = 1 - P(Z<1.25)
P(X<15) = 1 - 0.8944
P(X<15) = 0.1056
Hence, the probability that pizza takes less than 15 minutes to be delivered is 0.1056 = 10.56%
-1/5 * n ≤ 17
n ≥ -17/5 is the answer
Answer: Change each mixed number to an improper fraction.
Step-by-step explanation:
Answer:
change of slope= 35x
at 10 hours= 350
Step-by-step explanation:
Since it is going by 2 hours, you would divide by 2 to get each hour, then multiply by 10 to get 10 hours
