Answer:
Step-by-step explanation:
Given the function :
y=x³ - 3x² - 9x + 2. The largest and smallest values of the function at interval [-2, 4]
We substitute x values in the interval (-2 to 4) into the equation and solve for y
At x = - 2
y = (-2)³ - 3(-2)² - 9(-2) + 2 = 0
At x = - 1
y = (-1)³ - 3(-1)² - 9(-1) + 2 = 7
At x = 0
y = (-0)³ - 3(-0)² - 9(-0) + 2 = 2
At x = 1
y = (1)³ - 3(1)² - 9(1) + 2 = - 9
At x = 2
y = (2)³ - 3(2)² - 9(2) + 2 = - 20
At x = 3
y = (3)³ - 3(3)² - 9(3) + 2 = - 25
At x = 4
y = (4)³ - 3(4)² - 9(4) + 2 = - 18

Domain for the bottom graph
D: [-6,0)
R: (-6,5]
The last number line the correct answer!
-2a-5>3
-2a>8
a<-4
( the sign is flipped in the end because when you multiply or divide by a negative number, the sign flips the other way around)
Answer:
The standard deviation of the sample is 0.0064.
Step-by-step explanation:
The standard deviation of a sample of length n of a population with standard deviation 
is given by the following formula:
In this problem, we have that:
61 randomly selected gas stations. This means that 
The standard error of the mean is $0.05. This means that 
.
What is the standard deviation of the sample?
The standard deviation of the sample is 0.0064.
Answer:
30
Step-by-step explanation:
If Rodger has 15 cups of punch. There are glasses that have a 1/2 cup capacity. This means he is going to divide a 15 cups into 1/2 cups.
15/1 x 2/1 = 30/1
This means he will have 30 cups to fill.
