The average clothes washer uses 15 gallons of water per load, with a standard deviation of 3.0 gallons. What is the probability that a random sample of 90 loads will provide a sample mean within one half gallon of the population mean

0.866

Step-by-step explanation:

Given that:

Mean gallon (m) = 15

Standard deviation (σ) = 3

Sample size (n) = 90

Using the relation :

Zscore = (x - m) / (σ/√n)

The zscore being within 1.5 of population mean

-1.5 < z < 1.5

From z distribution table :

0.93319 - 0.0668

= 0.866

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
