ABC trucking company realized that on an annual basis that distance traveled is normally distrubuted with a mean of 50,000 miles and a standard deviation of 12,000 HOw many miles will be traveled by at least 80% of the trucks

39896 miles will be traveled by at least 80% of the trucks

Step-by-step explanation:

Given that :

the mean   = 50000

standard deviation   = 12000

we are to calculate how many miles  will be traveled by at least 80% of the trucks.

This implies that :

Likewise;

We all know that

Using the z table to determine the value for (invNorm (0.2)); we have ;

From z tables;

Thus; 39896 miles will be traveled by at least 80% of the trucks

answer: can you me with homework?

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
