Draw four boxes. Put five balloons in one box with the characters in them and write 1/4 under that box. Then draw five balloons in the other boxes, then draw one big box with the total amount of balloons in them.
Answer:
Option D, 1
Step-by-step explanation:
<u>Step 1: Determine what x1, x2, y1, y2 are</u>
Slope = 
(x1, y1) is (2, 8)
(x2, y2) is (6, 12)
<u>Step 2: Plug into the formula to get the slope</u>
Slope =
Slope = 
Slope = 
<em>Slope = 1</em>

Answer: Option D, 1
Answer:
A
Step-by-step explanation:
Given
x - 4 = - 2 ( add 4 to both sides )
x = 2 ( multiply both sides by 6 to clear the fraction )
5x = 12 ( divide both sides by 5 )
x = 
= 2 
→ A
Answer:
The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159
Step-by-step explanation:
According to the given data we have the following:
mean = μ= 22
standard deviation = σ = 2
n = 100
μx = 22
σx=σ/√n=2/√100=0.2
Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2
=P(z<-1)
= 0.159
The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159
