slope for horizontal lines is always 0.
y = 0x - 5
OR
y = -5
Answer:
$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05
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 zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
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 pvalue, we get the probability that the value of the measure is greater than X.
Normally distributed with mean $480 and standard deviation $20.
This means that ![\mu = 480, \sigma = 20](https://tex.z-dn.net/?f=%5Cmu%20%3D%20480%2C%20%5Csigma%20%3D%2020)
How much should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05?
This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95, so X when Z = 1.645.
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![1.645 = \frac{X - 480}{20}](https://tex.z-dn.net/?f=1.645%20%3D%20%5Cfrac%7BX%20-%20480%7D%7B20%7D)
![X - 480 = 1.645*20](https://tex.z-dn.net/?f=X%20-%20480%20%3D%201.645%2A20)
![X = 512.9](https://tex.z-dn.net/?f=X%20%3D%20512.9)
$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05
Answer:
y < 2,000 - 2x
Step-by-step explanation:
Solution:-
- The number of adult ticket sold = x
- The number of children ticket sold = y
- The profit from a adult ticket, L1 = $15
- The profit from a adult ticket, L2 = $7.5
- The amount of profit ( P )made by selling "x" adult tickets and "y" children tickets:
P = L1*x + L2*y
P = 15x + 7.5y
Where, We are to set up an equality for Profit P < $15000:
15x + 7.5y < 150,000
- Re-arrange to develop the slope-intercept form of an inequality:
7.5y < 150,000 - 15x
y < 2,000 - 2x
Where, the slope = -2 and intercept = $2,000
First you are going to do 1+2 and then you are going to do 6 divided by 2 then multiply them and that’s your answer the answer is 9
