Add the equations.
x-y%2B0.5x%2By=7%2B5
1.5x=12
highlight%28x=8%29
Now use either equation to solve for y.
8-y=7
highlight%28y=1%29
x=8
y=1
Those are the ranges for one tandard deviation below the mean and one standard deviation above the mean, and we know that 68% of the data falls in that range, so the probability that a randomly chosen worker makes that much is 68%
Answer: The commission is paid according to sales amounts that are likely to vary from month to month.
Step-by-step explanation: Instead of a salary that is paid in the same amount on a schedule, the commission may be very large one month and very small or zero at other times.
Financial planning usually includes monthly payments that and predictable expenses for food, transportation, utilities, etc. The person who earns a commission must remember to set aside some of the "extra" to cover these expenses. And be prepared to work more or harder at some times to make sales when they don't come easily.
The minimum and maximum of the set alone is 25 and 60. The range of that 35. So, the number is not less than or more than 25 or 60.
The set in order:
25, 36, 48, 52, 60
The median is 48, so the number has to be less than 48. Let's see if the number may be less than 36.
36+48
84
42
So, the number is right between 36 and 48.
43.5×2
87
Let's subtract 48 from that
87-48
39
So, the mssing value is 39. Let's check.
25, 36, 39, 48, 52, 60
48+39
87÷2
43.5
So the missing value is 39.
First, let's subtract both sides by 4:
|2x - 3| = 13
We can get two different equations from this:
2x - 3 = 13
and
2x - 3 = -13
So:
2x = 16
2x = -10
x = 8, x = -5
The solution set is {8, -5}
