Answer:
The sales level that has only a 3% chance of being exceeded next year is $3.67 million.
Step-by-step explanation:
When the distribution is normal, we use 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.
In this question, we have that:
In millions of dollars,
Determine the sales level that has only a 3% chance of being exceeded next year.
This is the 100 - 3 = 97th percentile, which is X when Z has a pvalue of 0.97. So X when Z = 1.88.
The sales level that has only a 3% chance of being exceeded next year is $3.67 million.

All you need to do is 45 divided by 15.
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.
Lets find out...
-5 - (-2) = -5 + 2 = -3....-3 is greater then -5
-1 - (-3) = -1 + 3 = 2.....2 is greater then -1
-4 - (-2) = -4 + 2 = -2...-2 is greater then -4
so it looks like it is going to be greater then the number u started with.
The vertical line is solid, so it must contain the solution so the inequality must contain equal to.
Because the shaded region is to the right of the line the solution has to be greater than.
The equation would be X ≥ -2
