Answer:
Incomplete question, but you use the normal distribution to solve it, with 
and 
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average waiting time to be seated for dinner at a popular restaurant is 23.5 minutes, with a standard deviation of 3.6 minutes.
This means that 
Thus
Find the probability that the patron will have to wait:
More than X minutes:
1 subtracted by the p-value of Z
Between A and B minutes:
p-value of Z when X = A subtracted by the p-value of Z when Z = B.
Less than X minutes.
p-value of Z.
Answer:
25
Step-by-step explanation:
When you substitute x for 3, the new equation would be ; 3(3)(2) - 2(3) + 13
using order of operations from left to right, you would start by multiplying
3(3)(2) and 3(3) is 9, and 9(2) is 18. The next step is to multiply 2 and 3 which is 6. Once you have both groups of numbers simplified, you can plug them back in : 18 - 6 + 13 ; 18 - 6 is 12, and 12 + 13 is 25, so the answer is 25.
Distributive property:
2x(x-4) = 2x^2 - 8x
Answer:
<u>The storage unit is 20 feet long.</u>
Step-by-step explanation:
1. Let's use the Pythagorean Theorem to find the unknown side or length of the storage unit:
With the information given, we have a right triangle with 52 feet of hypotenuse and 48 feet as one of its sides and width of the storage unit.
Length of the storage unit ² = Hypotenuse ² - Width of the storage unit ²
Replacing with the real values:
Length of the storage unit ² = 52² - 48²
Length of the storage unit ² = 2,704 - 2,304
Length of the storage unit ² = 400
√Length of the storage unit ² = √400
<u>Length of the storage unit = 20 feet</u>
