Linda randomly surveyed 20 teachers at her school about whether they prefer chalkboards or dry erase boards. She repeated the survey three times with three different sets of teachers.
A 3-column table with 3 rows. Column 1 has entries Sample 1, Sample 2, Sample 3. Column 2 is labeled Chalk with entries 12, 9, 1. Column 3 is labeled Dry Erase with entries 8, 11, 19.
Which pair of Linda’s samples seems to have the lowest variability and, therefore, are representative samples?
samples 1 and 2
samples 1 and 3
samples 2 and 3
none of the samples
Answer:
sample 1 and 2

parallel
I’ll give Brainliest. Due Soon.
Answer:
a and b are parallel, and so are t and s.
Step-by-step explanation:
By U-angles, a and b are parallel, because 108 + 72 = 180 degrees.
By corresponding angles and F-angles, t and s are parallel, because 108 = 108 degrees.
Math problem:
43 ÷ (7 − 3) × 2.
Answer: 21.5
Step-by-step explanation:
Answer:
21.50
Step-by-step explanation:
43 ÷ (7 − 3) × 2
According to order of operations you would do 7 - 3 first which gets you to 4.
43 ÷ 4 × 2
Now you would do 43 ÷ 4 which is 10.75 so next...
10.75 × 2
You should get an answer of 21.50
Hope this helps :D

What is the solution to the system?
y = 4x + 20
8x - 2y = -20
Answer:
-no solution-
Step-by-step explanation:
When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.
you plug in that variable to the other equation
8x - 2(4x + 20) = -20
and then you just solve the equation from there.
8x - 8x + 20 = -20
but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.
Complete this ratio table! (Look at your notes if you need a hint!)

Step-by-step explanation:
A wooden bench was originally priced at $50 but went on sale for 20% off. If Presley bought the wooden bench and paid a 5% sales tax, how much did he pay in total?
Answer:
$42.00
Step-by-step explanation:
20% OF 50 = 40
Before Tax Price: $40.00
Sale Tax: 5.00% or $2.00
After Tax Price: $42.00
Answer:
$42
Step-by-step explanation:
To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).
You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

Tell whether the ratios form a proportion.
1 to 0.4 and 9 to 3.6
Answer:
no? cause one is negative and the other is positive and I'm guessing they both have to be the same
Step-by-step explanation:
3 = x
x 3
These are fractions btw
Cross multiply:
3 * 3 = x * x
Simplifying
3 * 3 = x * x
Multiply 3 * 3
9 = x * x
Multiply x * x
9 = x2
Solving
9 = x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x2' to each side of the equation.
9 + -1x2 = x2 + -1x2
Combine like terms: x2 + -1x2 = 0
9 + -1x2 = 0
Add '-9' to each side of the equation.
9 + -9 + -1x2 = 0 + -9
Combine like terms: 9 + -9 = 0
0 + -1x2 = 0 + -9
-1x2 = 0 + -9
Combine like terms: 0 + -9 = -9
-1x2 = -9
Divide each side by '-1'.
x2 = 9
Simplifying
x2 = 9
Take the square root of each side:
x = {-3, 3}
