Probability 1st card is a diamond.....13 diamonds in the deck....13/52 reduces to 1/4
replace
probability 2nd card will be black....there are 26 black cards.....26/52 reduces to 1/2
replace
probability 3rd card is an ace....4 aces in the deck...4/52 reduces to 1/13
probability for all of that happening : 1/4 * 1/2 * 1/13 = 1/104 or 0.0096 or 0.96%
Answer: Margin of error = 1932
Step-by-step explanation: <u>Margin</u> <u>of</u> <u>Error</u> is the amount of variation a survey's results have. In other words, it is understood as the measure of variation one can see if the same survey was taken multiple times.
Margin of error is calculated as
z is z-score related to the percentage of confidence, in this z = 2.576
σ is population standard deviation
n is how many individuals are there in the sample or population
With a new level of confidence of 99%:
ME =
ME = 2.576(750)
ME = 1932
The new margin of error would be 1932.
Answer:
30 + 2 + 0.04 + 0.003.
Step-by-step explanation:
848 (811+37)
Using the equation
-780 + 37x44=y
-780+ 1,628= 848
Answer:
The reasonable range is 0 ≤ y ≤ 11,110, while the mathematical range is y ≥ –20.25.
