Anew gas- and electric-powered hybrid car has recently hit the market. the distance traveled on 1 gallon of fuel is normally distributed with a mean of 65 miles and a standard deviation of 4 miles. find the probability of the following events. a. the car travels more than 70 miles per gallon. b. the car travels less than 60 miles per gallon. c. the car travels between 55 and 70 miles per gallon.

a. 0.1056    b. 0.1056   c. 0.8882

Step-by-step explanation:

Given : The distance traveled on 1 gallon of fuel is normally distributed with a mean of 65 miles and a standard deviation of 4 miles.

i.e.  and  

Let x represents the distance traveled on 1 gallon of fuel .

a. The probability that the car travels more than 70 miles per gallon :

b. The probability that the car travels less than 60 miles per gallon :

c. The probability that the car travels between 55 and 70 miles per gallon:

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
