The scatter plot shows the time spent watching TV, x, and the time spent doing homework, y, by each of 23 students last week. (a) What is the predicted time spent doing homework for a student who doesn't spend any time watching TV?
(b) For an increase of one hour in the time spent watching TV, what is the predicted decrease in the time spent doing homework?
(c) What is the predicted time spent doing homework for a student who spends hours watching TV?

its 4 because 2 times 2 is 4, if you double the number two you get four

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
