Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is 
.
We take the inverse cosine of both sides to get:
to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;
Then;
.
.
.
.
Or
.
In this case the answer will be B
<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>
The absolute value of 7 would be 7
Answer:
Your answer is C. 1/2 (16*6) = 48 square feet
Step-by-step explanation:
The formula to find the area of a triangle is A = b*h/2 (base times height divided by half)
First you need to multiply the base (6) by the height (16).
6*16 is 96.
Now you divide 96 by 2 or cut it in half.
96/2 (or cut in half) is 48.
Therefore your answer is C
