Remember you can do anything to an equation as long as you do it to both sides
8-(3+b)=b-9
remember the distributive property
a(b+c)=ab+ac
distribute that invisible -1
-(3+b)=-1(3+b)=-1(3)-1(b)=-3-b
8-3-b=b-9
add like terms
5-b=b-9
add b to both sides
5=2b-9
add 9 to both sides
14=2b
divide both sides by 2
7=b
b=7
Given:
<span>random sample of 520 adults
mean was 150
standard deviation was 4.5.
reported with a 95% confidence level, and the confidence interval for the study was 150 ± 0.39.
The range of </span><span>values that shows the confidence interval for the study is </span><span>149.61 to 150.39
150 + 0.39 = 150.39
150 - 0.39 = 149.61</span>
(8.4n+2n)= 10.4n thats for the left side. Then u are left with, 10n =2. Then 2/10 that means that n =.2

Answer:
s^(6/5) is the fifth root of s^6. It would be written like ∛s^6 except the little "3" should be replaced by a "5".
Hope I helped!
