PLZ HURRY!!! WILL MARK BRAINLIEST!!!! For several months, an ice-cream vendor collects data showing the number of cones sold in
2 answers:
Answer: D. The model predicts that for each additional degree that the high temperature is above 70°F, the total number of cones sold increases by 3.7.
Step-by-step explanation:
Given: The vendor finds that there is a positive linear association between c and t (number of cones sold in a day (c) and the number of degrees above 70°F(t) ) that is best modeled by the equation.
Since, 3.75 is the rate of change of number of cones per degrees above 70°F.
Hence, the model predicts that for each additional degree that the high temperature is above 70°F, the total number of cones sold increases by 3.7.

A picture can help.
The median to the long side divides the isosceles triangle into two right triangles with hypotenuse 10 and short leg 6. Thus the long leg (median of interest) is found by the Pythagorean theorem to be
... √(10² -6²) = √64 = 8
Then the midpoint of the short side is found to be 6 + (6/2) = 9 units to the side and 8/2 = 4 units above the opposite vertex. Hence the square of the length of that median is 9² + 4² = 97.
The sum of squares of interest is
... 8² + 2×97 = 258
