The table compares x, the number of minutes of television sam watched each day, to y, the number of minutes she spent exercising. the function y = –0.78x + 95 models the data in the table. which is the best prediction for the number of minutes of exercising sam will do if she spends 30 minutes watching television that day? 45 minutes 72 minutes 83 minutes 118 minutes

"The function y = –0.78x + 95 models the data in the table. Which is the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day?"

Just substitute 30 for x in the given function: f(30)= -0.78(30)+ 95.

71.6. She will exercise for about 72 minues on that day.

correct answers below:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
