Answer:
6
Step-by-step explanation:
43-7=36
36/6=6
X= -4
Explanation:
Lines with undefined slopes are vertical and the equations are in the form x=constant.
Answer: E. none of the above
Step-by-step explanation:
The given data values that represents the population:
2, 6, 3, and 1.
Number of values : n=4
Mean of the data values = 

Sum of the squares of the difference between each values and the mean =



Now , Variance = (Sum of the squares of the difference between each values and the mean ) ÷ (n)
= (14) ÷ (4)= 3.5
Hence, the variance is 3.5.
Therefore , the correct answer is "E. none of the above".
Answer:
- 25x³
Step-by-step explanation:
Given
(x + 5)(x - 5)x³ ← expand the factors using FOIL
= (x² - 25)x³ ← distribute
=
- 25x³
If they manage to sell
tickets, they will earn
dollars. We want this number to be at least 1000, so the inequality would be

In order to solve this for t, you only need to divide both sides by 15:

So, they need to sell at least 67 tickets to have an income of
dollars
