Answer:
4 trays should he prepared, if the owner wants a service level of at least 95%.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 5
Standard Deviation, σ = 1
We are given that the distribution of demand score is a bell shaped distribution that is a normal distribution.
Formula:
P(X > x) = 0.95
We have to find the value of x such that the probability is 0.95
P(X > x)
Calculation the value from standard normal z table, we have,
Hence, 4 trays should he prepared, if the owner wants a service level of at least 95%.
Answer:
a=2
Step-by-step explanation:
3(3a+2)+6=30
9a+6+6=30
9a+12=30
9a=18
a=2
Four times the sum of x and two
Answer:
x = 6
Step-by-step explanation:
An angle bisector divides the segments on either side of it so they are proportional. That is ...
x/12 = 5/10
x = 12(5/10) = 6 . . . . . multiply by 12
The interpretation of the slope in the context of the problem is: For every hour the electrician works, her pay will increase $28.
<h3>How to Interpret the Slope of a Function?</h3>
The slope of any function is the unit rate or average rate of change of the given function for that situation.
Given the function, E(x) = 130 + 28x, where:
E(x) is the amount an electrician charges per job
130 is the flat rate service which is the starting value or y-intercept
28 is the unit rate or slope, which is the fee charged per hour by the electrician to complete a job.
Thus, the interpretation of the slope in the context of the problem is: For every hour the electrician works, her pay will increase $28.
