second one is a i divide then ad sub and ad it again bye 3
srry if i am wrong
brainlyest would be nice ( ;
Step-by-step explanatnation
We are given the following in the question:
Sample size, n = 200
\hat{p} = 65\% = 0.65
Margin of error =
\pm 6.75\% = \pm 0.0675
\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}
\hat{p}\pm \text{Margin of error}
Putting values:
(0.65 \pm 0.0675)\\=(0.5825,0.7175)
Answer:
I think it's 2x/4 (1x/2 if simplified). if it's multiple choice that's what I'd go with and if that answer is wrong then sorry
Step-by-step explanation:
x•2 is 2x because you don't know the value x and you still have to divide by four. when simplified, 2/4 is 1/2 so it'd be 1x/2
Answer:
x-2 or 0≤x≤7

Answer:
12y + 11
Step-by-step explanation:
To add them you would add like terms. That means you would add those with y together and those without together.
8y + 4y + 6 + 5 = 12y + 11
If you want to solve for y, subtract 11 from both sides then divide both sides by 12.
