The D. O.T. collected data for a particular stretch of I-85 and found that the average speed was 70 mph with a standard deviation of 15 mph and the distribution is approximately normally distributed. The actual Speed Limit for the stretch of road is a maximum of 70 mph and minimum of 40 mph. What percentage of drivers actually drive between 40mph and 70 mph

it would be:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

answer: i don't understand it

step-by-step explanation: sorry
