PLEASE I REALLY NEED HELP Use a graphing calculator to find an equation of the line of best fit for the data in the table. Round the slope and y-intercept to the nearest tenth. Then Identify and interpret the correlation coefficient. $x$ 10.1 9.8 9.7 9.4 8.9 8.7 8.4 8.1
$y$ 3 11.8 6.7 4.6 9.5 3.6 6.3 7.2
The equation of the line of best fit is $y=$
.

To the nearest thousandth, the correlation coefficient is $r=$
.

Question 2
The correlation coefficient shows that the data has

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?

One side of a rectangle is 7 feet shorter than seven times the other side. find the length of the shorter side if we also know that the perimeter of the rectangle is 306 feet.

When you answer this can you explain
