The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
The answer would be C) As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.

Answer:
Hey there!
For the first question we use the triangle area formula: 1/2bh, or 1/2(8)(5). This gives us 20 for the area.
For the second question we get a trapezoid, since the cross section does not pass through the vertex.
Hope this helps :)
Answer: 40% chance
Sample space: 3 white 2 red, 5 pairs
2/5 probability, as a percent would be 40% chance
Answer:
=−3x+42
Step-by-step explanation:
Let's simplify step-by-step.
−4(x−7)+x+14
Distribute:
=(−4)(x)+(−4)(−7)+x+14
=−4x+28+x+14
Combine Like Terms:
=−4x+28+x+14
=(−4x+x)+(28+14)
=−3x+42
