So what you will need to do is subtract 2x - 3x = -x, then subtract three from both sides 8 - 3 and the answer will be -x + 5
What are you solving for?
Answer:
x=145
Step-by-step explanation:
There are two ways to solve:
-Vertical angles Theorem states that opposite angles are congruent, so x=145 degrees.
-Sameside angles are supplementary so:
35+x=180
Subtract 35 from both sides:
x=145
Answer: 385
Step-by-step explanation:
sample size n = pq(z/E)^2 = 0.6*(1-0.6)*(1.96/0.05)^2 =(NNN) NNN-NNNN
Round up to 369
Answer: 369
b. how large a sample would be necessary if no estimate were available for the proportion supporting current policy?
sample size n = pq(z/E)^2 = 0.5*0.5*(1.96/0.05)^2 = 384.16
Round up to 385
Answer: 385
