For the Unit Test the answer is A.
Answer: Lower = 1 Median = 2 Upper = 4
Upper ≠ 1 so statement is false
<u>Step-by-step explanation:</u>
The Lower quartile (Q1) is the left side of the box.<em> I estimate it to be 1.</em>
The Median (Q2) is the line dividing the box.<em> I estimate it to be 2.</em>
The Upper quartile (Q3) is the right side of the box.<em> I estimate it to be 4.</em>
<em />
The upper quartile is the 75th percentile. It is not 1 so the statement is false.
Answer:
x= -6/11 or x= -0.54
Step-by-step explanation:
Distribute into the parenthesis.
-5x-10-3x= 1x-4+2x
*In order to get rid of these parenthesis, multiply by an "invisible one"
Now, add or subtract the common multiples.
-8x-10= 3x-4
Then, move the variable to one side. You do that by adding 8x to both sides, since -8x is less than 3x.
-8x-10= 3x-4
+8x +8x
Once you've moved the variable to one side, add 4 to both sides.
-10= 11x-4
+4 +4
Then, divide both sides by 11 to isolate the variable.
<u>-6</u>= <u>11x</u>
11 11
This leaves you with..
x= -6/11 or x=-0.54

Answer:
Step-by-step explanation:
Given
0.2467467467........
We require 2 equations with the repeating part after the decimal point.
Let x = 0.2467467....
Multiply both sides by 10
10x = 2.467467... → (1)
Multiply both sides by 10000
10000x = 2467.467467.... → (2)
Subtract (1) from (2) to eliminate the repeating part
9990x = 2465 ( divide both sides by 9990 )
x = =
