A: the mean salary is $500.
400+500+600=1500/3=500
b: the median is $500 also.
The solution to x + 8.5 = 64.5 is 56.
x + 8.5 = 64.5
- 8.5 - 8.5
---------------------------
x = 56
Let's break this down:
The difference: Something's gotta be subtracted
Twice a number: So 2 times a number, or n
and 3: So we gotta subtract 2n and 3
is 11: The final answer is 11
So altogether is:
2n - 3 = 11
Answer:
either 45$ a year or divide it to days/months
Step-by-step explanation:
(x - 4)²
(x - 4)(x - 4)
x² - 4x - 4x + 16
x² - 8x +16
