The answer would be 27. When you replace x with 4 you get 3^4 which is 27
If a 99% confidence interval is constructed instead of a 95% confidence interval for the population mean, then <u>C. the resulting margin of error will increase and the risk of reporting an incorrect interval will decrease</u>.
<u>Step-by-step explanation</u>:
The margin of error helps in mentioning the amount of random sampling error that occurred in a survey. Increase in the margin of error, makes the result less confidence. So the margin of error of the survey should be less.
The margin of error can be calculated in two different ways:
One is using the standard deviation of population,
Margin of error = Critical value x Standard deviation for the population
Other is using standard error of sample,
Margin of error = Critical value x Standard error of the sample
That would be the bottom left one....because all of the others are spaced evenly
Slope = -1
x-intercept = 3/-1 = -3.00000
f-intercept = 3/-1 = -3.00000
Slope = 0.667/2.000 = 0.333
x-intercept = 3/-1 = -3.00000
f-intercept = 3/3 = 1
Slope = 0.400/2.000 = 0.200
x-intercept = 3/-1 = -3.00000
f-intercept = 3/5 = 0.60000
Slope = 0.286/2.000 = 0.143
x-intercept = 3/-1 = -3.00000
f-intercept = 3/7 = 0.42857
Answer:
R3 Theorem: If parallel lines are cut by a transversal, then alternate interior angles are congruent.
R4 Theorem: Congruence of segments is reflexive.
