Mean = Sum of all the observations/ Number of observations = (87+46+90+78+89)/5 = 78
Variance = SD^2 ------ SD = Standard deviation
It means that with Variance, square root is never taken.
Therefore,
Variance = Summation of square of differences between observation and the mean divided by the number of observations.
That is,
Variance = {(87-78)^2 + (46-78)^2 + (90-78)^2 + (78-78)^2 + (89-78)^2}/5 = 274
A. A = -10 x, B = -4
<u>Explanation:</u>
Given:
For A:
The Quotient of the Operation is -5 x
The Divisor of the Operation is 2
So the remainder is -10 x
For B:
The Quotient of the Operation is -2
The Divisor of the Operation is +2
So the remainder is -4
So, the missing values in the table is A = -10 x and B = -4
Answer: Long -term capital gain
Step-by-step explanation:
Serena is single, so based on the Taxpayer Relief Act of 1997, she would pay no capital gains tax on the first $250,000 gain.
Therefore, $300,000 - $250,000 = $50,000
<em>The remaining $50,000 gain is taxable because of her being single and it has been her principal residence for three years.</em>
Answer:
C. -31m⁴n - 8m²
Step-by-step explanation:
Given:
(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
Required:
Determine an expression equivalent to it
Solution:
(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
Distribute the negative sign to open the parentheses
9mn - 19m⁴n - 8m² - 12m⁴n - 9mn
Combine like terms
9mn - 9mn - 19m⁴n - 12m⁴n - 8m²
-31m⁴n - 8m²
Therefore, -31m⁴n - 8m² is an equivalent expression of (9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
