Billy was doing push-ups at a rate of 30 per minute. How long did it take him to complete 150 push-ups?​

Given Billy doesn't slow down, or takes a break he'll complete 150 pushups in 5 minutes

Step-by-step explanation:

150 pushups / 30 a minute 150/30=5

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
