The answer to this question would be: <span>The new survey’s margin of error will be between 50% and 100% the size of the original survey’s margin of error.
A bigger sample will result in a narrower margin of error which is a good thing because your data will become more accurate. But twice size will not improve the margin into the half. It definitely became lower than 100% though
</span>
9.5% x 34.50= 3.28
34.50+3.28= 37.78
Answer:
7 x (x+3) =2
Step-by-step explanation:
hi, so in order to get the answer we need to find the key words, in this case ‘times’ and ‘sum’ is telling us multiplication and addition
so in the second part, its telling us to use x, the variable as the number that wasn’t identified which is filling the space for us.
and once we’ve figured all those little clues we have our answer
so we’re going to have 7 first, then multiplied by x+3 which equals 2
hope u got it!!.
