The Commutative Property of Addition
Step-by-step explanation:
They have a common denominator of 12
21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups
or you could group ingredients with the same denominators
7/4+1/4+1/2+1/2+5/3+1/3=
8/4+2/2+6/3=
2+1+2=5
The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.
What is the OUTPUT if the input to the equation y=2x - 7 is x =4?

Write the equation of the line, given the y and x-intercepts.
y-intercept = –2, x-intercept = –3
Answer:
[tex]y=\frac{-2}{3}x -2[/tex]
Step-by-step explanation:
Y-intercept = (0,-2) X-intercept = (-3,0)
*Use either coordinates in the equation
y=mx+b
[tex]0=\frac{-2}{3}(-3)+b\\ 0=\frac{6}{3} +b\\0=2+b\\0-2=b\\-2=b[/tex]
So, final equation is [tex]y=\frac{-2}{3}x -2[/tex]
a survey of 80 high school students was given to determine how many people were in favor of forming a new rugby team. the school will form the team if at least 30% of the students at the school want the team to be formed. out of the 80 surveyed, 12 said they wanted the team to be formed. to test the significance of the survey, a simulation was done assuming 30% of the students wanted the team, each with a sample size of 80, repeated 100 times. what conclusion can be drawn using the simulation results?
The conclusion that can be drawn using the simulation results depends on comparing the actual proportion to the distribution of proportions obtained from the simulation and assessing the statistical significance of the survey result.
To draw a conclusion using the simulation results, we need to compare the proportion of students in favor of forming a new rugby team in the actual survey to the results of the simulation assuming 30% of the students want the team.In the actual survey, out of 80 students, 12 said they wanted the team to be formed. This corresponds to a proportion of 12/80 = 0.15 or 15%.In the simulation, assuming 30% of the students want the team, repeated 100 times with a sample size of 80, we can compare the distribution of proportions obtained from the simulations to the actual proportion.If the actual proportion of 15% falls within the range of proportions obtained from the simulation, it suggests that the result of the survey is not statistically significant. If the actual proportion is significantly lower than the range of proportions obtained from the simulation, it indicates that the result of the survey is statistically significant and that forming a new rugby team may not be supported by the majority of the students.The conclusion that can be drawn using the simulation results depends on comparing the actual proportion to the distribution of proportions obtained from the simulation and assessing the statistical significance of the survey result.For more such questions on simulation

1. (15 points =5 ′×3) Draw two indifference curves (IC) for each of the following pairs of goods and indicate which IC provides a higher utility. Put the quantity of the 1st good on the horizontal axis and the quantity of the 2 nd good on the vertical axis. 1.1 Rhonda likes carrots and dislikes broccoli. 1.2 Emily likes hip-hop iTunes downloads and does not care about heavy metal downloads. 1.3 Steven dislikes both potatoes and fish. Each fish he eats decreases his utility by a smaller amount that the previous fish.
1.1 For Rhonda, who likes carrots and dislikes broccoli, the indifference curves would show a higher level of utility as they move away from broccoli and towards more carrots. The indifference curve representing a higher utility would be the one farther away from the origin and closer to the carrots axis.
This indicates that Rhonda prefers more carrots and less broccoli, and each indifference curve represents a different level of utility. 1.2 For Emily, who likes hip-hop iTunes downloads and doesn't care about heavy metal downloads, the indifference curves would be upward sloping. As the quantity of hip-hop iTunes downloads increases, Emily's utility would increase. Since she doesn't care about heavy metal downloads, the specific shape of the indifference curves would depend on the individual preferences within the hip-hop downloads. The indifference curve representing a higher utility would be the one farther away from the origin and representing a larger quantity of hip-hop iTunes downloads.
1.3 For Steven, who dislikes both potatoes and fish, the indifference curves would be downward sloping. As the quantity of potatoes and fish increases, Steven's utility would decrease. However, the statement mentions that the utility decrease for each additional fish is smaller than the previous one. This suggests that the indifference curves would have a diminishing slope as they move away from the origin. The indifference curve representing a higher utility would be the one closer to the origin, indicating a lower quantity of potatoes and fish.

Joanna is driving from Orlando, FL to Dallas, TX. The distance between Orlando and Dallas is 1,084 miles. Joanna's average rate of speed is 65 mph. The following function represents how many miles Joanna has left on her trip after t hours, F(t)=1084-65t.
After how many hours of driving will Joanna be 304 miles from Dallas?
_______ hours.
*Hint, the f(t) is given in the word problems as 304 miles. Plug the 304 in place of the f(t) and solve for t using inverse operations.
Answer:
12 hours
Step-by-step explanation:
We are given the function [ F(t) = 1084 - 65t ]
t represents the time so we are going to solve for f(t).
Substitute and solve
304 = 1084 - 65t
~Subtract 1084 to both sides
-780 = -65t
~Divide -65 to both sides
12 = t

What is the length of SV?
Answer:
31
Step-by-step explanation:
ST + TU+ UV = SV
13+6+ 2x-18 = 4x-29
Combine like terms
2x+1 = 4x-29
Subtract 2x from each side
2x+1-2x = 4x-29-2x
1 = 2x-29
Add 29 from each side
1+29 = 2x-29+29
30 =2x
Divide each side by 2
30/2 = 2x/2
15 =x
We want to find the length of SV
SV = 4x-29
= 4*15-29
= 60-29
= 31
4. ( 6x²y + 3ab)(6x²y -3ab) = ( _____ ) - 9a²b²
Answer:
The answer is;
36x^4y^2 - 9a^2b^2
Step-by-step explanation:
Here, we simply want to write the right hand side in the form of the left hand side.
The best route to use here is the route of the difference of two squares.
Say we have the value a^2-b^2
We can simply write this as (a-b)(a + b)
This looks similar to what we have in the question above. What is left is just to
multiply the term 6x^y together and place it before the subtraction sign.
Mathematically;
6x^2y * 6x^2y = 36x^4y^2
A circular pie with a diameter of 18 inches is cut into 12 equal slices. What is the approximate area of one slice?
Answer:
The approximate area of one slice is 21.21 in².
Step-by-step explanation:
Area = πr²
d = 18 in
r = 18 in/2
r = 9 inches
Solve for the area of the pie
A = π(9in)²
A = 81π in²
OR
A = 254.47 in²
Since the pie is cut into 12 slices, we will divide the area by 12
A = 81π in²/12
A = 6.75π in² ---in terms of pi
OR
A = 254.47 in²
A = 21.21 in²

3 more than 7 times a number x is 47
Answer:
x = 44/7
Step-by-step explanation:
7x+3 = 47

7x = 44
Divide by 7
7x/7 = 44/7
x = 44/7
Using approximations to 1 significant figure,
estimate the value of
0.482 x 61.2^2 / square root 98.01
URGENT!
please help i have 5 mins left of my test
Answer:
200
Step-by-step explanation:
Given:
0.482 x 61.2^2 ÷ √98.01
61.2^2 = 3745.44
√98.01 = 9.9
So,
0.482 × 3745.44 ÷ 9.9
= 1,805.30208 ÷ 9.9
= 182.35374545454
To one significant figure
= 200
One significant figure means only 1 non zero value and others are zero
The approximation to 1 significant figure of the result is 200
Given that:
To express [tex]\dfrac{0.482 \times 61.2^2}{\sqrt{98.01}}\\[/tex] with approximation to 1 significant figure.
The calculations will go like this:
[tex]\dfrac{0.482 \times 3745.44}{\sqrt{98.01}}\\\\=\dfrac{1805.302}{9.9}\\\\\approx 182.35\\[/tex]
Significant figure 1 means only 1 non zero digit should be present and rest places can be having zeros.
Rounding to 1 significant figure:
200
Thus, the result approximated to 1 significant figure is 200.
