PLZ HELP EXPLAIN A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the collected data, the least-squares regression line is ŷ = 3.27 + 2.14x, where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line? For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.
For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
For each increase of one text per minute, there is an estimated increase in age of 3.27 years.
For each increase of one text per minute, there is an estimated increase in age of 2.14 years.
The slope has no meaning because the units of measure for x and y are not the same.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

your answer would be 12

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
