Given the following statements<span>
1. line RS || segment AB, ∠1=∠2
2. ∠B = ∠1
3. ∠A = ∠2
4. ∠A = ∠B
5. RA = RB
and the following reasons,
a) If lines ||, corresponding ∠'s are =
b) If two ∠'s of a triangle are =, sides opposite are =
b) If lines ||, alternate interior ∠'s =
c) Given
d) Substitution
</span>
<span>we match the statements and the reasons to enable us prove the required proof.

Answer: 95% confidence interval would be (1341.2,1458.8).
Step-by-step explanation:
Since we have given that
n = 64
Average = 1400
Standard deviation = 240
We need to find the 95% confidence interval for SAT scores.
So, z = 1.96
So, Interval would be
Hence, 95% confidence interval would be (1341.2,1458.8).
Answer:
I am not sure what you mean by simplifying to a single power of 3 but 3^6 x 3 would be the power 3 over 7 = 3^7
