The time it takes students in a cooking school to learn how to prepare a particular meal is a random variable with a mean of 3.2 hours and a standard deviation of 1.9 hours. Find the probability that the average time it will take 38 students to learn how to prepare the meal a) is less than 3.4 hours (Draw the bell curve) 4 b) is between 3.0 hours and 3.6 hours (Draw the bell curve)

ask i dont know either ; (

step-by-step explanation:

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
