easured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree days, where a day's degree-days are the number of degrees its average temperature falls below 65 degrees
f. over a 23-month period. By looking at the equation of the least-squares regression line (ŷ = 85 + 16x), you can see that the correlation between amount of gas used and degree-days is

The regression line equation is y=85+16x, the value of the slope is shown as constant 16 and it's a positive constant, hence the correlation between the amount of gas used and degree of the days is a POSITIVE correlation.

A line has a slope of 3/7 and a y-intercept of 0. What is it’s equation in slope-intercept form?
Ilia_Sergeevich [38]

Answer:

y = 3/7x

Step-by-step explanation:

Well slope-intercept form means this -----> y=mx+b

m = slope

b = y- intercept

In the question given they already telling us the slope (3/7) and the y intercept (0) so to put it into slope intercept form it will be ---> y= 3/7x

* If your y - intercept is zero you don't need to replace it with the b because its zero it means nothing (it has no value)

Hope this helps!!!

tara bakes 225 cookies in 5 hours, and she uses 8 pounds of sugar. she divide 225 by 5 to grt a rate of 45. which of the followi
Sati [7]

Options :

A cookies per pound

B. O pounds per hour

c. cookies per hour

D. hours per cookie

Answer: C.) Cookies per hour

Step-by-step explanation:

Given the following :

Number of cookies baked = 225 cookies

Total time taken = 5 hours

Amount of sugar used = 8 pounds

Tara divides 225 by 5; 225 / 5 = 45

Rate gives the amount or number of times something occurs within a given period, Hence

The rate obtained by Tara corresponds to the ratio of ; (Total cookies baked / total time taken) = (225 / 5), this translates to the amount or number of cookies baked within an hour.

F(x) = |3x-4| give the domain and range
gulaghasi [49]

Answer:

Domain: -∞≤x≤∞

Range: 0≤F(x)≤∞

Step-by-step explanation:

The x variable can take any value.

In the case of F(x), the function only can take positive values, due to the absolute value function, and the function does not have any other restriction.
