7/8=x/48
x=(7/8)48
x=(7)(48/8)
x=(7)(6)
x=42
D.42
Answer:
≈50.6
Step-by-step explanation:
Not sure what precision level this problem is looking for, but for right-skewed distributions, we know that the mean is going to be pulled right and therefore the mean should be larger than the median. To a high confidence level, the mean should fall between 50 and 59, or in the third column.
If a single estimation is wanted, assume the values inside each column are uniformly distributed:
Distribute each term in one parenthesis to the other terms in the other parenthesis.
(x - 2) (2x + 3)
First, distribute x. When distributing, multiply
x(2x) = 2x²
x(3) = 3x
Next, distribute the other term, -2. Remember to change the signs.
-2(2x) = -4x
-2(3) = -6
-------------------------------------------------------------------------------------------------------------------
2x² + 3x - 4x - 6
Combine like terms
3x - 4x = -x
2x² - x - 6
-------------------------------------------------------------------------------------------------------------------
2x² - x - 6 is your answer
