Answer:
Chicago marathon runners
Step-by-step explanation:
Due to the strict qualifying time, the runners of the Boston marathon are going to very prepared, and quite close in their times. Since they are going to be close, the standard deviation is expected to be small.
Otherwise, in the Chicago marathon, anyone can run. This means that along with the professional runners, who are going to be very prepared, other unprepared runners will compete, and they are going to take a long time to complete the race, adding variation to the finishing times. The standard deviation is the square root of the variance, so since the variance for the Chicago marathon will be higher, the standard deviation also will
0.25q + 0.10d = 1.25
q + d = 8....q = 8 - d
0.25(8 - d) + 0.10d = 1.25
2 - 0.25d + 0.10d = 1.25
-0.25d + 0.10d = 1.25 - 2
-0.15d = - 0.75
d = -0.75/-0.15
d = 5 <=== there are 5 dimes
q + d = 8
q + 5 = 8
q = 8 - 5
q = 3 <=== there are 3 quarters
a salesperson earns $175 per week plus a commission equal to 4% of her sales. This week her goal is to earn no less than $525.
Let x be the amount of sales in dollars
Commission = 4% of her sales x = 4% of x = 0.04 * x= 0.04 x
a salesperson earns $175 per week + 0.04 x
so Amount of earning in a week = 0.04 x + 175
This week her goal is to earn no less than $525.
So amount of earning is greater than 525
0.04 x + 175 >= 525
The required expression is 0.04 x + 175 ≥ 525
