Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.

Answer:
side A is 18.75 cm² greater than side B
Step-by-step explanation:
area of A = 12.5 x 7.5 = 93.75 cm²
area of B = 10 x 7.5 = 75 cm²
93.75 - 75 = 18.75 cm²
 
        
             
        
        
        
Complete question :
Select the two statements that are true about the equation y−10=60(x−40)
Answer:
m = 60
One point on the line is (40, 10)
Step-by-step explanation:
Given the equation :
y−10=60(x−40)
Comparing the equation with the point slope equation formula :
y - y1 = m(x - x1)
Where, x1 and y1 are points on the line 
m = Slope 
From here, we can deduce that:
y1 = 10 ; x1 = 40 and m = 60
(x1, y1) = (40, 10)
m = slope = 40
