A study is given in which scientists examined data on mean sea surface temperatures (in degrees Celsius) and mean coral growth (in millimeters per year) over a several-year period at different locations. Here are the data: Sea Surface Temperature 29.67 29.88 30.17 30.21 30.48 30.66 30.90
Growth 2.63 2.57 2.67 2.70 2.48 2.39 2.27

a. Use your calculator to find the mean and standard deviation of both sea surface temperature x and growth y and the correlation r between x and y.
b. Use the regression function to find the least-squares line.

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

hi there, i would be interested to you with your test, may you add the questions and answer options.

- : )

the cost function, c(x), is the total cost of manufacturing x units of the product. how many units must the company produce and sell if they wish to make a b. if the company produces and sells 2000 units, would they obtain a profit or loss?

answer is  

c.
