Employees were asked how many times per week they exercised. The frequency table shows the results of the survey.

Number of times exercised per week 0 1 2 3 4 5 6 7 8

Frequency 5 10 2 9 33 12 15 3 1

(a) Create a probability distribution table from the frequency table. Round probabilities to the nearest hundredth.

Find:

(b) P (x < 4)

(c) P (x = 6)

(d) P (x ≥ 5)

Step-by-step explanation:

Given the frequency table

a) The total sum is

Create a probability distribution table

b) The probability

c) The probability

d) The probability

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

(3x-8) or (3x+8)
