The average amount of electricty consumed by a household in a day is strongly correlated to the average daily temperature for that day. This relationship is given by y=0.503x+3.31 where x
is the temperature in F and y
is the amount of electricity consumed in kilowatt-hours (kWh).

What does the y-intercept of this function represent?

the answer is c

step-by-step explanation:

figure c

step-by-step explanation:

hope this .

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
