Answer:
1.) 8 People are not expected to pay.
2.) If 12 clients do not pay the day of their appointment it is more than the average person who does not pay on that day.
Step-by-step explanation:
400*.98=392
400-392=8
The average amount of people that do not pay is 8.
(a) the slope is 2 and y-intercept is 15
slope is the factor in front of x
y-intercept is obtained by setting x=0: y=2*0+15 = 15
(b) the rate of change (aka slope) is 2 baskets per hour. This means that every additional hour of picking there are 2 more baskets of berries than before. The initial amount is 15. This means that there were 15 baskets of berried picked before starting counting the hours.

Answer:
32%
Step-by-step explanation:
Let x be the mean of the values and σ their standard deviation.
Since the minimum value of the diameter of the washers is 1.53 mm, then
x - σ = 1.53 mm (1)
Also, the maximum value of the diameter of the washers is 1.65 mm, then
x + σ = 1.65 mm (2)
Adding (1) and (2), we have
x - σ = 1.53 mm
+
x + σ = 1.65 mm
2x = 3.18
x = 3.18/2
x = 1.59 mm
Subtracting (1) and (2), we have
x - σ = 1.53 mm
-
x + σ = 1.65 mm
-2σ = -0.12
σ = -0.12/-2
σ = 0.06 mm
Since the diameter of the washers are required to be between 1.53 millimeters and 1.65 millimeters long, and x - σ = 1.53 mm to x + σ = 1.65 mm are the required values, 68% of the washers lie in this range. The other values lie outside this range. The amount that the factory would have to discard is 100% - 68% = 32%
