Step-by-step explanation:
<u>Step 1: Define
</u>
y = home runs
x = hits
[Best Line of Fit] y = 0.15x - 1.5
<em>We can use this to predict the average of the scatter plot.
</em>
hits = x = 200 times
<u>Step 2: Solve for </u><em><u>y</u></em><u> home runs</u>
- Substitute [BLF]: y = 0.15(200) - 1.5
- Multiply: y = 30 - 1.5
- Subtract: y = 28.5
Remember that this is only a <em>prediction.</em> Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.

Answer:
the nth term is 2^n-3 because we see that each number is being multiplied by 2
Answer:
(a+2) Is your answer
Step-by-step explanation:
You could try synthetic division, but it's pretty complicated (not to mention for much harder problems), so you should try factoring this. What two numbers multiply up to 10 and add up to 7? Using trial and error, we would find these two numbers to be 2 and 5. Therefore, it factors into (a+5)(a+2).
