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.

This is the same as saying x = 3 and x = 7.
========================================
Work Shown:
Plug x = 3 into f(x)
f(x) = (1/2)*|x-3| + 3
f(3) = (1/2)*|3-3| + 3
f(3) = 0.5*|0| + 3
f(3) = 0.5*0 + 3
f(3) = 0 + 3
f(3) = 3
-----------------------
Plug x = 5 into f(x)
f(x) = (1/2)*|x-3| + 3
f(5) = (1/2)*|5-3| + 3
f(5) = 0.5*|2| + 3
f(5) = 0.5*2 + 3
f(5) = 1 + 3
f(5) = 4
-----------------------
Plug x = 7 into f(x)
f(x) = (1/2)*|x-3| + 3
f(7) = (1/2)*|7-3| + 3
f(7) = 0.5*|4| + 3
f(7) = 0.5*4 + 3
f(7) = 2 + 3
f(7) = 5
-----------------------
Plug x = 3 into g(x)
g(x) = sqrt(x-3) + 3
g(3) = sqrt(3-3) + 3
g(3) = sqrt(0) + 3
g(3) = 0 + 3
g(3) = 3
-----------------------
Plug x = 5 into g(x)
g(x) = sqrt(x-3) + 3
g(5) = sqrt(5-3) + 3
g(5) = sqrt(2) + 3
g(5) = 1.414214 + 3
g(5) = 4.414214 ..... which is approximate
-----------------------
Plug x = 7 into g(x)
g(x) = sqrt(x-3) + 3
g(7) = sqrt(7-3) + 3
g(7) = sqrt(4) + 3
g(7) = 2 + 3
g(7) = 5
-----------------------
To summarize everything, refer to the table below.
The rows highlighted in yellow refer to when f(x) = g(x)
This happens twice when x = 3 and x = 7
If x = 3, then f(x) = g(x) = 3
If x = 7, then f(x) = g(x) = 5
Therefore, x = 3 and x = 7 are two solutions to f(x) = g(x)
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 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).

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.

Out of 40 students in class 8,20% were absent.How many students were present?
Answer:
32 students were present.
Step-by-step explanation:
To find out how many students were present in class 8, we have to find out how many students were absent first.
As the question has already provided us, the number of students who are absent would be [tex]40 \cdot 20\%[/tex], which equals to [tex]40 \cdot \frac{20}{100}[/tex] which is 8 students in total who were absent in class 8.
Now that we have found out how many students were absent, simply subtract the number of students who were absent from the total number of students in class 8, which is (40 - 8) = 32 students, and you have the number of students that were present: 32.
Hope this helped!

the number of ducks in a pond was 345. If 33 1/3% of the ducks flew away. how many were left
Answer: 230 ducks were left.
Step-by-step explanation:
Answer:
31 ducks
Step-by-step explanation:
345 ÷ 33 1/3% = ducks left.
345 ÷ 33 1/3% = approximately 31
So once solved, you can conclude that there are 31 ducks left in the pond.

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!

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.
Given sinθ = 2/5 and cosθ < 0:
1. Find cscθ
2. Find cotθ
Recall that
sin²(θ) + cos²(θ) = 1
for all θ, and given that cos(θ) < 0, we find that
cos(θ) = -√(1 - sin²(θ)) = -√(1 - (2/5)²) = -√(21)/5
Now,
csc(θ) = 1/sin(θ) = 1/(2/5) = 5/2
and
cot(θ) = cos(θ)/sin(θ) = (-√(21)/5)/(2/5) = -√(21)/2
