Describe how to select a stratified random sample of 36 people hired by ETS to score the AP Statistics Exams. Explain your choice of strata.
Answer:
The strata will be the category of people with at least 3 years of working experience scoring AP Statistics
Step-by-step explanation:
The strata will be the category of people with at least 3 years of working experience scoring AP Statistics Exams.
I will use this strata because it is only those with a track record of scoring AP Statistics Exams that can rightly score for ETS. People who don't have the right amount of experience of scoring AP Statistics exam may need some training because they need to understand the specifics on how to grade some questions and respective answers.
A kangaroo hops 2 kilometers in 3 minutes. At this rate, how far does the kangaroo travel in 2 minutes? *
Answer:
At a speed of 2 km every 3 minutes, in 2 minutes the kangaroo would travel 1,333 km.
Step-by-step explanation:
If a kangaroo hops 2 kilometers in 3 minutes, to calculate how much distance this animal hops in 2 minutes, the following calculation should be performed:
2 km / 3 min = 0.666 km per minute (2/3 x 2)
0.666 km per minute x 2 minutes = 1.333 kilometers in 2 minutes (0.666 x 2)
Therefore, at a speed of 2 km every 3 minutes, in 2 minutes the kangaroo would hop 1,333 km.

rename fraction to similar fraction 6/8 and2/12=
Answer:
6/8=18/24
2/12 = 4/24
Step-by-step explanation:
If you want to make the fractions the same, look at the denominator.
6/8 and 2/12
what number can both 8 and 12 go into?
It goes into 24
so 6/8 would be 6*3 and 8*3 because whatever you do to the bottom, you do to the top and 8*3 is 24 so 6*3 is 18 and for 2/12 you multiply both by 2 since 12*2=24 and 2*2=4
I will do 6/8 only. You do the other fraction.
Pick a number, any number. How about 2?
Multiply the top and bottom number by 2.
6 x 2 = 12
8 x 2 = 16
We get 12/16.
Reducing 12/16 to the lowest terms we get 3/4.
Another fraction similar to 6/8 is 3/4. In fact, they are equivalent fractions.
Do the other fraction in like fashion.
Note: Each fraction given has more than one similar fraction.

](6^3 - 9)/23]4
Evaluate this expression
The value of the expression is [(6^3 - 9)/23]4 = 36
How to evaluate the expression?The expression is given as:
[(6^3 - 9)/23]4
Evaluate the exponent
[(6^3 - 9)/23]4 = [(216- 9)/23]4
Evaluate the quotient and the difference
[(6^3 - 9)/23]4 = [9]4
Evaluate the product
[(6^3 - 9)/23]4 = 36
Hence, the value of the expression is [(6^3 - 9)/23]4 = 36

Is it necessary to check for an extraneous solution for the equation below? How do you know? ( I attached the image with equation)
No, it is not is not necessary because we don't have any division by zero issues that will come up. If we had a variable in the denominator, then it would be a different story.
-----------------------
If you're curious about solving this equation, then you would first multiply both sides by the LCD 15 to clear out the fractions.
(6w-1)/5 - 3w/1 = (12w-16)/15
15*[ (6w-1)/5 - 3w/1 ] = 15*[ (12w-16)/15 ]
15*[ (6w-1)/5 ] - 15*[ 3w/1 ] = 15*[ (12w-16)/15 ]
3(6w-1) - 15(3w) = 12w-16
18w-3 - 45w = 12w-16
-27w-3 = 12w-16
-3+16 = 12w+27w
13 = 39w
39w = 13
w = 13/39
w = 1/3
To check this answer, you plug it back into the original equation. You should get the same thing on both sides when you simplify fully. Again we don't have to worry about extraneous solutions because we don't have any division by zero issues.

The sale price of every item in a store is 85% of its usual price.
a. The usual price of a backpack is $30, what is its sale price? $
25.5
b. The usual price of a sweatshirt is $18, what is its sale price? $
Answer
a. The backpack is $4.50
b. The sweatshirt is $2.70
Step-by-step explanation:
a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)

The first number in the list is -4.
Each number is 3 more than the number before it.
This means,
Second number = -4 + 3 = -1
Third number = -1 + 3 = 2
Fourth number = 2 + 3 = 5
Fifth number = 5 + 3 = 8

The fifth number is 8.
