Answer:  choice F) m/26 = 12

=======================================================

Work Shown:

mpg = miles per gallon

mpg = miles/gallon

To find the mpg, we divide the number of miles driven over the number of gallons of gas used. For instance, if we can drive 100 miles on 5 gallons of gas, then we get 100/5 = 20 mpg

In this problem, we don't know how many miles we can travel. So m is the placeholder for that number. We know that we use 12 gallons of gas. So we have

mpg = miles/gallon

mpg = m/12

We're told Shannon gets 26 mpg, which allows us to say m/12 = 26

--------------------

Unfortunately m/12 = 26 doesn't match any of the answers. But we can do a bit of algebra to transform things.

Start off multiplying both sides by 12

m/12 = 26

12*(m/12) = 12*26

m = 12*26

Then divide both sides by 26

m = 12*26

m/26 = 12*26/26

m/26 = 12

which matches with choice F

A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and stan
Galina-37 [17]

Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15

<u><em>Step(ii):</em></u>-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

             = 1-P(Z>1.15)

             =  1-( 0.5+A(1.15)

             =  0.5 - A(1.15)

             = 0.5 - 0.3749

             = 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251
