Problem 3
Reem wants to swim at least 600 laps in a pool every month. How many laps does she need to
swim each day to reach her goal? Create an inequality for the situation. (Assume a month to be
30 days).

Problem 4
Rufus owns a painting company. Each of his employees can paint 85 square feet per hour. The
house they are working on next has 1360 square feet of walls to paint.
a. If he wants to have the house done in two hours what is the minimum number of
employees he will need?

Problem 3: 20 laps per day,

Inequality: x >=20 per day

Problem 4: minimum of 8 employees

Step-by-step explanation:

Given that the goal is 600 laps in a month

And a month contains 30days, to achieve 600 laps, we divide 600 laps by 30 days

= 600/30= 20

Reem needs to swim a minimum of 20 laps per day to achieve her goal.

Inequality: x should be greater than or equal to 20 laps daily.

x >= 20

Problem 4:

Given that each employee can paint 85square feet per hour

The building has 1360 square feet and to be completed in two hours

Number of employees to complete the job in one hourwill be 1360/85 = 16

If 16 employees will complete 1360 per hour, then 8 employees will complete the work in 2 hours.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
