Step-by-step explanation:
78% of those surveyed bought popcorn statistic or parameter. This means that significantly more than half of the given population bought popcorn statistic or parameter.
If the population is, say ten thousand, then 78% of 10000 is
10000 × 78/100 = 7800.
Which is more than half the whole population.

A 5x2=10 I think it’s right
<u>3x-7(4+2x)=-x+2</u> first step is to distribute the -7 into the (4+2x) this is done by multiplying the -7 to the 4 and them doing the same for the 2x
<u>3x-28-14x=-x+2</u> next you combine like terms as in all the x's you do this by adding the -14x and the 3x together
<u>-11x-28=-x+2 </u> next you put all the x's on one side
<u>+x +x</u>
<u>-10x-28=2</u> <u />next you add 28 to both sides to combine your final like terms
<u>+28 +28
-10x=30</u> the last step is to divide -10x and 30
<u>/-10x /-10x
</u><u>x=-3</u>
