Answer:
Removing the outlier decreases the number of data by one and therefore you must decrease the divisor. For instance, when you find the mean of 0,10,10,12,12, you must divide the sum by 5, but when you remove the outlier of 0,you must then divide by 4.
Step-by-step explanation:
1256.64 is the area, because you use this equation- A=πr^2
Answer:
x² + 3x - 28
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(x + 7)(x - 4)
= x(x - 4) + 7(x - 4) ← distribute both parenthesis
= x² - 4x + 7x - 28 ← collect like terms
= x² + 3x - 28
