In politics, marketing, etc. We often want to estimate a percentage or proportion p. One calculation in statistical polling is t

he margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 32% with a margin of error of 2.2%. Describe the conclusion about p using an absolute value inequality.

The absolute inequality regarding p is represented as |p - 72%| ≤ 4%. This reflects that with an initial 72% poll result and a margin of error of 4%, p likely falls between 68% and 76%, indicating the potential range of p.

If R is the midpoint of QS, RS=2X-4, ST=4X-1, and RT=8X-43, find QS
zzz [12365]
RT equals RS plus ST
8x - 43 = 2x - 4 + 4x - 1
Simplify: 8x - 43 = 6x - 5
Bring variables to one side: 8x - 6x = -5 + 43
2x = 38
Divide both sides by 2:
x = 19

Calculate QS as twice RS:
QS = 2 * RS = 2 * (2x - 4) = 2 * (2*19 - 4) = 2 * 34 = 68

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?
Inessa [12570]
12 m^2/h to cm^2/min

12 m^2/h × 1 h/60 min = 0.2 m^2/min

0.2 m^2/min × 10000 cm^2/1 m^2 = 2000 cm^2/min

2000 cm^2/min

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zina [12379]

P(S) = Probability of Smash = 0.05 (5%)
P(M) = Probability of Modest = 0.5 (50%)
P(F) = Probability of Flop = 0.45 (45%)
Based on this, we utilize the model for discrete random variables, leading to:
E(X) = (0.05 * 5.2) + (0.5 * 0.9) + (0.45 * 0)
= 0.26 + 0.45 + 0
= 0.71 Mill'
