The duration of routine operations at Charlotte General has approximately a normal distribution with an average of 125 minutes and a standard deviation of 18 minutes. a. What proportion of operations last at least 120 minutes?

b. What proportion of operations lasted between 90 and 130 minutes?

c. What proportion of operations lasted less than 122 minutes?

the answer would be c:   ax + b = ax + c

step-by-step explanation:

35-60 students are taking math.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the answer is $42.96
