Answer:

Step-by-step explanation:

Mean income of 99 people = $ 400

Sum of income of 99 people = 400 * 99 = $ 39600

Income of a woman = $ 1500

Income of 100 people = 39600 + 1500 = $41100

Mean of 100 people = 41100/100 = $411

411 - 400 = $11

Mean income increases by $11

The new mean will be (400*99+1500)/100=411
The mean increased by 11.

Tameron is driving 540 miles to college. If he drives at an average rate of 45 miles per hour, how many hours will it take him t
andreev551 [17]
Given:
540 miles to college
average rate of 45 miles per hour

How many hours will it take him to get 3/4 of the way there?

540 miles * 3/4 = (540 * 3) / 4 = 1620/4 = 405 miles

405 miles / 45 mph = 9 hours.

It would take Tameron 9 hours to travel 3/4 of the way there.

An electrician charges $35 per hour plus a fixed amount for residential work. For a job that took 6 hours, he billed $270. Write
Alexeev081 [22]
With the information provided, we can begin with the equation:

y=35x + b

With x = number of hours, y = total cost, b = fixed amount that is charged for residential work

We know that after 6 hours, $270 was charged:

$270 = $35(6) + b

Solve for b:

b = $270 - $210 = $60

The fixed amount that is charged for residential work is $60. So now we can rewrite the equation as:

y = 35x + 60
