Zoey is trying to calculate the -score for a problem in her math textbook. The problem states that a student takes a stress test and receives a score of 144 on the test with the mean of 128, a median of 125, a range of 75, and a standard deviation of 34. Which of the following will she need to calculate the -score? Select all that apply. a. 34
b. 75
c. 125
d. 128
e. 144

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year. how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

Explain why the factor 1.5 is broke. into two numbers in the model.
