What I did for this question is I set up ans equation. 5x-7 + 3x+11 = 180 and I added the Xs and and I added 11 to -7. Then I got 8x+4=180. I then "-4" on both sides and then divided 8 by 176. Getting X as 22. We now know X and we put 22 into the equation for D which is "3x+11" getting 77 degrees. Hope this helped!

Hello!
The variable of interest is:
X: Number of people that support the candidate.
You need to calculate the sample size to estimate the population proportion of supporters given a confidence level of 99% and a margin of error of 4%
The margin of error of the confidence level for the population proportion is
d= 
* 
From this formula you have to clear the value of n:
=
= 
= 
n= 
sample proportion "p'" since there is no sample information, nor any previous information is known, you have to consider it as the "worse case scenario" and use the value of p'= 0.50
d= 0.04
She has to take a sample of 1045 people to estimate the population proportion of her supporters with a confidence level of 99% and a margin of error of 4%
I hope this helps!
The first one is isosceles because it has two side lengths that are the same, C.
The missing angle measure is 35° because all of them together should add up to 180° and 105+40+35=180, A.
The possible lengths for the third triangle e are in between 7, and 17. This is because the possible side lengths are in between adding the two side lengths together, (12+5=17) and subtracting the littler side by the bigger side. (12-5=7)
Answer:
45 cm
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
b = 3 + 2 = 5
A = 1/2(5)(6)
A = 15
Area of a rectangle:
A = bh
A = 12*2.5
A = 30
Combined:
30 + 15 = 45
