For science class, a student recorded the high and low temperatures, in Fahrenheit, over a ten day period in September. The data is shown in the table. Low Temperature, x 26 28 30 32 34 35 37 38 41 45
High Temperature, y 49 50 57 54 60 58 64 66 63 72
What is the correlation for a linear model of this data? Round to the nearest hundredth.
Ten high and low temperatures in October are recorded and have a correlation coefficient of 0.89. In which month is there a stronger correlation between the high and low temperatures? Explain your answer. Please EXPLAIN you answer

Which is the most efficient first step to solve x in the equation 3.7x - 18 = -4.3x -34 a. add 3.7x to both sides of the equation. b. add 4.3x to both sides of the equation. c. subtract 18 from both sides of the equation. d. subtract 34 from both sides of the equation.

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:
