Answer:
6b+b^2 (b to the 2nd power)
Step-by-step explanation:
8b+b^2-2b (b to the 2nd power)
(8b-2b)+b^2
6b+b^2
Hopefully this helps :)
Answer:
= 
(3n + 7)
Step-by-step explanation:
We require to find the first term a₁ and the common difference d
The n th term is given by 3n + 2, thus
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
d = 8 - 5 = 3
= [ 2a₁ + (n - 1)d ], substitute values
= [ (2 × 5) + 3(n - 1) ] = (10 + 3n - 3) = (3n + 7)
Answer:
D.
Step-by-step explanation:
In direct variations, we would have:
Where <em>k</em> is some constant.
Since this is indirect variation, instead of that, we would have:
To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>
<em />
<em />
Now plug this back into the variation:
The answer is D.
Answer:
oof
Step-by-step explanation:
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
