Answer:
$2948 and $4030
Step-by-step explanation:
The CI is sample mean +/- s/sqrt(n)
t(0.95,df=63 critical values are |t|>1.669
90% CI is 3489+/-1.669*(2595/8) since sqrt(64)=8
the interval is 541.38
round to 541
the interval is 3489+/-541
($2948,$4030) is the 90% CI for the mean.
First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10
X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90
<span>When creating a subset of 5 elements from 7 elements, order should not matter. Therefore, we use the combination formula over the permutation formula.
The combination formula given n elements total and r elements used is n! / [r!*(n-r)!]. Substituting 7 for n and 5 for r, we get:
7! / (5!*2!) = 7*6 / 2 = 21
21 subsets can be created</span>
