Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5
Answer:
Tina
Step-by-step explanation:
bc if you sub in 4 for x the equations on both sides are 0
check:
-4 + 4 = 0 -3 x 4 = -12
0 x 3 = 0 12 + -12 = 0
0 = 0

The null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
First, let us understand the Null and Alternative hypotheses:
The null hypothesis is simply to predict that there is no effect of the relationship between the variables.
The alternative hypothesis is to state the research prediction of a relationship or effect. In this case, the newsletter publisher believes that below 68% of their readers own a Rolls Royce.
The null hypothesis is that the proportion of readers who own a Rolls Royce is equal to 0.68.
Null hypotheses = H₀: p = 0.68
The alternate hypothesis is that the proportion of readers who own a Rolls Royce is below 0.68.
Alternate hypotheses = H₁: p < 0.68.
Thus, the null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.

The answer is 12. You got the right answer.
I got this answer by doing PEMDAS.
First I answered the numbers in the parentheses and the brackets. then i multiplied the numbers in the brackets by the outside number which got me to twelve.
