Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. She finds the mean is 78. Her steps for finding the variance are shown below.
What is the first error she made in computing the variance?
A.) Emi failed to find the difference of 89 - 78 correctly.
B.) Emi divided by N - 1 instead of N.
C.) Emi evaluated (46 - 78)2 as -(32)2.
D.) Emi forgot to take the square root of -135.6.
Answers
Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2
Explanation:
The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.
The outcome of the first event does affect the outcome of the second, so that the probability is changed
Answers
Answer:
Dependent Events
Step-by-step explanation:
Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.
If the first ball is chosen the probability will 1/3 leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3. In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.
In this the events are called dependent events.
Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.

Jeans cost $38. The tax is 8% what is the total cost?
Reporting if wrong, please explain.’
Answers
Answer:
$41.04
Step-by-step explanation:
8% = 0.08
38(0.08) = 3.04
$3.04 is the tax for the jeans. Now we just have to add it to the price.
38 + 3.04 = $41.04
Answer:
$41.04
Step-by-step explanation:
0.08 (the tax converted from percentage) x 38 (initial cost) = 3.04(tax amount)
38(initial amount) + tax amount (3.04) = 41.04
the cost after tax is $41.04
understand now? To convert 8% to a decimal just move the decimal to the left twice (because we’re representing out of 100%)
