Answer:
B. To determine the percent of adults in the country who believe the federal government wastes 51 cents or more of every dollar.
Step-by-step explanation:
Given that:
sample size = 1026
sample proportion = 0.36
Margin of error = 55% = 0.55
Confidence interval level = 99%
The purpose of this question is to determine the research objective:
The research objectives indicate the intention of the study, the objectives,\ or the main idea. This main idea arises from a need (the research problem) and refined into specific questions (i.e. the research questions). From, the given information, the research objective is to determine the percent of adults in the country who believe the federal government wastes 51 cents or more of every dollar.
Answer:
f(9) =21
Step-by-step explanation:
I will assume you want to find f(9) when x=9
Let x=9
f(9) = 2(9) +3
= 18+3
=21
f(9) =21
Answer:
$1,065,597.22
Step-by-step explanation:
Simple interest = Principal * Rate * Time/100
10,510 = P * 12 * 30/365*100
10,510*365*100 = 360P
383,615,000 = 360P
Note that the time was converted to years by dividing by 365
P = 383,615,000/360
P = $1,065,597.22
Hence the principal is $1,065,597.22
Answer:
Expected value of the game: -$0.421
Expected loss in 1000 games: $421
Step-by-step explanation:
There are two possible outcomes for the event:
- There is a 1 in 38 chance of winning $280
- There is a 37 in 38 chance of losing $8
The expected value for a single game is:
![E(X) = \frac{1}{38}*\$280-\frac{37}{38}*\$8\\E(X)=-\$0.421](https://tex.z-dn.net/?f=E%28X%29%20%3D%20%5Cfrac%7B1%7D%7B38%7D%2A%5C%24280-%5Cfrac%7B37%7D%7B38%7D%2A%5C%248%5C%5CE%28X%29%3D-%5C%240.421)
The expected value of the game is -$0.421
In 1,000 plays, the expected loss is:
![L = 1,000*-\$0.421\\L=-\$421](https://tex.z-dn.net/?f=L%20%3D%201%2C000%2A-%5C%240.421%5C%5CL%3D-%5C%24421)
You would expect to lose $421.
answer the original number is 6
(5x + 2 - 10) *2 = 44
10x + -16 = 44
10x = 60
x=6
