Consider the following data: Step 3 of 3: Calculate the value of the range. 3,10, -3, -4, – 11, −5

Given the following data, find the weight that represents the 31st percentile. Weights of Newborn Babies 7.9 7.6 6.5 7.9 7.4 8.5 6.2 6.9 9.2 7.8 00 7.4 7.0 6.5 7.9 8.2

Calculate the percentage change of the variable in each of the following cases. Then calculate the percentage change if the movement is occurring in the opposite direction, with what was the final value now the initial value and vice versa. Now calculate a comparable percentage change using the average of the initial and ending values. Express all three changes in absolute value form without positive or negative signs and as whole numbers (i.e. 67%, not 66.6%). a. A fast-food restaurant, which originally sold hamburgers at a price of $5, increases their price to $6. The absolute value of this percentage change is %, and the absolute value of the percentage change calculated using the average of the two values is %, the absolute value of the percentage change in the opposite direction is %. b. The number of autos sold monthly at a car dealership drops from 400 to 300. The absolute value of this percentage change is %, the absolute value of the percentage change in the opposite direction…

For the straight line defined by the points (1,53) and (3,91) , determine the slope ( ? ) and y-intercept ( ? ). Do not round the answers.

A high school has 44 players on the football team. The summary of the players' weights is given in the box plot. What is the interquartile range of the players' weights? 159 154 213 253 268 -∞ 150 160 170 180 190 200 210 220 230 240 250 260 270 00 Weight (in pounds)

Use the graph to determine the units of the slope and the ?y‑intercept.

Jack is a discus thrower and hopes to make it to the Olympics some day. He has researched the distance (in meters) of each men's gold medal discus throw from the Olympics from 1920 to 1964.  Below is the equation of the line of best fit Jack found. y=0.34x+44.63y=0.34x+44.63 When calculating his line of best fit, Jack let x represent the number of years since 1920 (so x=0 represents 1920 and x=4 represents 1924).  Using the line of best fit, estimate the distance Jack should be able to throw in order to be able to win the 2020 Olympics.
