He scatter plot shows the test scores of a group of students who played games online for different amounts of time in a day: A scatter plot is shown. The x-axis is labeled Hours spent playing games online. The y-axis is labeled Test scores. Data points are located at 0.1 and 99, 0.5 and 97, 0.7 and 89, 1.5 and 85, 2 and 75, 2.5 and 70, 2.75 and 78, 3.2 and 62, 3.5 and 52, 3.6 and 75, 4.2 and 52, 5.6 and 40, 6 and 75, 7.2 and 38, 8 and 33.

What will most likely be the effect on the test scores of students if the number of hours they play games online increases?

Test scores will decrease because the graph shows a negative association.
Test scores will increase because the graph shows a positive association.
Test scores will increase because the graph shows a negative association.
Test scores will decrease because the graph shows a positive association.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
