Answer:
0.0062 = 0.62% probability that a randomly selected truck from the fleet will have to be inspected
Step-by-step explanation:
Z-score
Problems of normally distributed samples 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:
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.
What is the probability that a randomly selected truck from the fleet will have to be inspected?
Values of Z above 2.5. So this probability is 1 subtracted by the pvalue of Z = 2.5.
Z = 2.5 has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.0062 = 0.62% probability that a randomly selected truck from the fleet will have to be inspected
Answer:
y=2.50x+4.00
over here the gradient is 2.50
and the y-intercept is 4.00
so in the first one, start Drawing the line from 4 on y axis
So a few points would be: (0,4) (1,6.5) (2,9) (3,11.5) (4,14)
second equation...
y=2.00x+5.00
gradient is 2.00
and y intercept is 5
so draw the line from 5 on the y axis
A few points would be: (0,5) (1,7) (2,9) (3,11) (4,13)
As you see, I got the common point (2,9) in both, so they intersect at (2,9)
