0
The
The variance is 10.
The standard deviation is 30,
The mean is 80
The median is 40.
The data point x = 20 is 2 standard deviations from the mean.
The data point x = 50 is 1 standard deviation from the mean,
The data point x = 45 has a z-value of 1,5

three-fourths of an hour

36÷48=0.75

0.75=

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.
