Answer:
a. 8.5
b. 10
Step-by-step explanation:
a.) 1, 1, 2, 7, 7, 10, 12, 16, 20, 34
Since 7 and 10 are tied in the middle, then we need to find a number in the middle of the two.
8.5 is in the middle of 7 and 10, therefore 8.5 is the mean.
b.) We need to do the same thing we did before, except add 22 to it's directed place:
1, 1, 2, 7, 7, 10, 12, 16, 20, 22, 34
Since 10 is in the middle, 10 is the new mean.
Hope this helps! :D

Test Practice When Xavier buys his lunch, he saves the nickel
gets as change. How much money will Xavier have if he buys his
lunch 4 times one week and 2 times the second week?
Understanding:
First of all, each time Xavier buys lunch he saves a nickel. That means if he buys lunch twice, he is saving 2 nickels, buys 3 times he saves 3 nickels, and so on. To solve this problem we can simply add the times he bought lunch and that will equal the value of nickles he saved so far.
Solution:
First-week savings = 4 nickels
Second-week savings = 2 nickels
Simply, adding those together gives us 6 nickels.

Does anyone know how to do Polygons on the Coordinate Plane
I need your email
Answer:
You can use the coordinates of a figure to find its dimensions by finding the distance between two points. To find the distance between two points with the same x-coordinates, subtract their y-coordinates. To find the distance between two points with the same y-coordinates, subtract their x-coordinates.

100 students were asked to ll out a form with three survey questions, as follows: H: Honor Roll
C: Club membership (Robotics Club or Gaming Club)
D: Double-major
Survey results were as follows:
28 checked H (possibly non-exclusively), 26 checked C (possibly non-exclusively), 14 checked D (possibly non-exclusively)
8 checked H and C (possibly. non-exclusively), 4 checked H and D (possibly. non- exclusively), 3 checked C and D (possibly. non-exclusively)
And 2 checked all three statements.
1. How many students didn't check any of the boxes?
2. How many students checked exactly two boxes?
3. How many students checked at LEAST two boxes?
4. How many students checked the Clubs box only? [d]
Answer:
1. 45
2. 9
3. 11
4. 17
Step-by-step explanation:
The computation is shown below:
Given that
28 checked H
26 checked C
14 checked D
8 checked H and C
4 checked H and D
3 checked C and D
2 checked all.
Based on the above information
N(H)=28
N(C) 26
N(D) 14
N(H∪C) = 8
N(H∪D) = 4
[tex]N(C\cup D)=3[/tex]
[tex]N(H\cup C\cup D)=2[/tex]
We know that
[tex]Total=N(H)+N(C)+N(D)-N(H\cup C)-N(H\cup D)-N(C\cup D)+N(H\cup C\cup D)[/tex]
= 28 + 26 + 14 - 8 - 4 - 3 + 2
= 55
1. The students who didnt check any kind of the box is
= 100 - 55
= 45
2) Students who checked exactly two boxes is
[tex]= N(H\cup C)+N(H\cup D)+N(C\cup D)-3N(H\cup C\cup D)[/tex]
= 8 + 4 + 3 - 6
= 9
3) Students who checked a minimum of two boxes
[tex]= N(H\cup C)+N(H\cup D)+N(C\cup D)-2N(H\cup C\cup D)[/tex]
= 8 + 4 + 3 - 4
= 11
4) Given N(C) = 26
Now we have to deduct N(C∪D) and N(H∪C) as it could be checked aside from the club
= 26 - 8 - 3
= 15
Here the [tex]N(H\cup C\cup D)[/tex] could be deducted twice under both categories so it would be added one time to neutralize
= 15 + 2
= 17

Is 17/40 closest to 0/40, 20/40, or 40/40?
Answer:
20/40
Step-by-step explanation:
If you make them decimals, then 17/40 = .43
0/40= .00 20/40 = .50 40/40 =1.00
so .50 is closest to .43.

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s height is 4 feet, 2 inches.
1. Should Clare's or the doctor's measurement be considered the actual height? Explain your reasoning.
2. What was the error, expressed in inches? (Hint: 12 inches = 1 foot, so 12 is the unit rate to multiply the number of feet by)
Amount of Error = difference between Actual and estimated guess
3. What was the error, expressed as a percentage of the actual height?
Percent Error = Amount of Error x 100

Answer:
1. Yes2. 2 inches3. 4%Step-by-step explanation:
Estimated height is 4 feetMeasured height is 4 feet 2 inches1. The measurement is actual and should be considered as such. Estimate is approximate most of the time.
2. The error is:
4 feet 2 inches - 4 feet = 2 inches3. Percent error:
2 inches/4 feet 2 inches × 100% =2 inches / 50 inches × 100% =0.04× 100% = 4%The Student Council sold the following items at the home football game. A B C D E F 1 Item Number Price Income Cost Per Sold Item 2 lollipops 85 $0.25 $21.25 $0.12 3 Gummies 48 $0.35 $16.80 $0.18 4 Bubble Gum 79 $0.45 $35.55 $0.22 5 Combos 46 $0.55 $25.30 $0.26 $ $ $ 16! DHE $ 6. TOTAL $50.72
If n stands for number sold and c stands for cost per item, in which column would you use the formula: n x c?
A; Column D
B: Column E
C: Column F
D: Column G
Answer: D: Column G
Step-by-step explanation:
If n is the number of items sold and c is the cost per item, multiplying n and c would give the total expenses for selling that item.
As expenses are in column G, this is therefore the right column to use n * c.
This is can be proven by using the Lollipops as an example.
n = 85
c = $0.12
n * c = 85 * 0.12 = $10.20
$10.20 is the amount of expenses for lollipops in Column G so Column G must be right.

The two graduates with the greatest GPA from each of 14 randomly selected law schools were recruited to investigate a new method of preparation for a law exam. For each school, one student was randomly assigned to prepare using the standard method and the other student was assigned to prepare using the new method. At the end of the preparation, all 28 students were given the same exam, and their scores were recorded. Why can we conclude cause and effect from this type of study
Incomplete question. The missing question read;
Which of the following best describes why a matched-pairs design is an appropriate design for the investigation?
a. Each graduate was randomly assigned to one method.
b. The law schools were randomly selected.
c. Each method served as a block.
d. The sample size was less than 30.
e. Each law school served as a block, and the graduates were paired within each law school and randomly assigned to one of the two methods.
Answer:
e. Each law school served as a block, and the graduates were paired within each law school and randomly assigned to one of the two methods.
Step-by-step explanation:
Note, the matched pairs design is typically used when the experiment has two independent variables (treatment conditions), so the subjects of the experiment are grouped into pairs based on some common variable relationship they have before been randomly assigned to the treatment conditions.
In this case, the graduates were paired within each law school and randomly assigned to one of the two methods (the two treatment conditions).

Answer:
The answer is x= 50 and y=50.
Step-by-step explanation:
So a straight line is always equal to 180 degrees. So, to find the length of the inner angle, subtract 100 from 180= 80. Now that you've gotten the value of that angle, you'll have to find x and y. All angles of a triangle add up to 180 degrees. 180-80= 100. The small dash on both of those lines means they are equal. Do 100/2 = 50. Hope this helps!
You go to a bakery and see that two cookies
and a glass of milk cost $3.75. One cookie with a
glass of milk cost $2.45. How much will a glass of
milk cost alone? Start by writing a system of
equations, then solve the system.
Answer:
$1.15
Step-by-step explanation:
You take 3.75 - 2.45 = 1.3 because the 2.45 is taking off the price of one cookie and than when you minus them you get the price of how much the cookie alone costed. then take 2.45 - 1.3 to get how much the milk costs.
could you help me find whqt equivalent to 16x^2/y
Answer:
(2xy)⁴/x²y⁵
(4x)²/y
(4x)²y¯¹
Step-by-step explanation:
From the question given above, we obtained:
16x²/y
Thus, we can obtain the equivalent of the above expression as follow:
For Option 1:
(2x)⁴/x²y¯¹ = 2⁴x⁴/x²y¯¹
(2x)⁴/x²y¯¹ = 16x⁴/x²y¯¹
Recall:
1/A¯¹ = A
Therefore,
16x⁴/x²y¯¹ = 16x⁴y/x²
Recall:
Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ
Therefore,
16x⁴y/x² = 16x⁴¯²y = 16x²y
(2x)⁴/x²y¯¹ = 16x²y
Thus, (2x)⁴/x²y¯¹ is not equivalent to 16x²/y
For Option 2:
(2xy)⁴/x²y⁵ = 2⁴x⁴y⁴/x²y⁵
(2xy)⁴/x²y⁵ = 16x⁴y⁴/x²y⁵
Recall:
Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ
16x⁴¯² y⁴¯⁵ = 16x²y¯¹
Recall:
A¯¹ = 1/A
16x²y¯¹ = 16x²/y
(2xy)⁴/x²y⁵ = 16x²/y
Thus, (2xy)⁴/x²y⁵ is equivalent to 16x²/y
For Option 3:
(4x)²/y = 4²x²/y
(4x)²/y = 16x²/y
Thus, (4x)²/y is equivalent to 16x²/y
For Option 4:
(4x)²y¯¹ = 4²x²y¯¹
(4x)²y¯¹ = 16x²y¯¹
Recall:
A¯¹ = 1/A
16x²y¯¹ = 16x²/y
(4x)²y¯¹ = 16x²/y
Thus, (4x)²y¯¹ is equivalent to 16x²/y
For Option 5:
(4x/y)²
Recall:
(A/B)ⁿ = Aⁿ / Bⁿ
(4x/y)² = (4x)²/y²
(4x/y)² = 4²x²/y²
(4x/y)² = 16x²/y²
Thus, (4x/y)² is not equivalent to 16x²/y
SUMMARY:
(2x)⁴/x²y¯¹ is not equivalent to 16x²/y
(2xy)⁴/x²y⁵ is equivalent to 16x²/y
(4x)²/y is equivalent to 16x²/y
(4x)²y¯¹ is equivalent to 16x²/y
(4x/y)² is not equivalent to 16x²/y
