Answer: C) Always false
====================================================
Explanation:
A linear pair of angles satisfy these two requirements (both must be true)
The angles are adjacentThe angles are supplementary, ie they add to 180.While it is possible for vertical angles to be supplementary (they both are 90), it is not possible for vertical angles to be adjacent. This is because vertical angles do not share a common side. Vertical angles are opposite one another, so they are as far from adjacent as possible, while still sharing a common vertex point however.
This means that vertical angles are never considered to be a linear pair. Put another way, you can ask yourself "can vertical angles form a straight line?". The answer is "they can never form a straight line". Again the fact they aren't adjacent is the reason why.
Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.
Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?
4.25 inches
5.25 inches
4.75 inches
5.75 inches
Thank you!
Answer:
4.75
Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.
The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.
What is Z-score?A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The Z-score of +1 is,
(x-μ)/σ = 1
(5-μ)/σ = 1
5 - μ = σ
The Z-score of +2 is,
(5.25-μ)/σ = 2
(5.25 - μ)/σ = 2
5.25 - μ = 2σ
Substitute the value of the 'σ', therefore, standard deviation from the above,
5.25 - μ = 2(5 - μ)
5.25 - μ = 10 - 2μ
5.25 - 10 = -2μ + μ
μ = 4.75
Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x
Answer:
y = 2x - 1
Step-by-step explanation:
y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.
Answer:
y=2x-1
Step-by-step explanation:
notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:
80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
4) Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.
Answer:
210 student's
Step-by-step explanation:
80 students chose the aquarium.
60 students chose the science center.
30 students chose the planetarium.
40 students chose the farm.
The students can't vote for more than one place, so you just add all the numbers together.
80 + 60 + 30 + 40 = 210 students

The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. The adult tickets sold for $7.50 each and the student tickets sold for $4.50 each. If the junior class collected $2,212.50 in ticket sales, how many student tickets did the class sell
**No answer choices, please explain how you got the answer cause I have no clue how to do this**
❤❤
Answer: I believe this is correct, i got 80 tickets
Step-by-step explanation:
I divided 2212.50 by the adult tickets, 7.50, and got 295. if the adults sold 295 tickets, then the students would have sold 80, because thats all that were left. I hope I helped
The number of student tickets the class sold is 200.
Let
x = number of student ticket sold
y = number of adult ticket sold
The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. Therefore,
Total tickets:x + y = 375The junior class collected $2,212.50 in ticket sales. Therefore,
Total sold:4.50x + 7.50y = 2212.50Combine the equation to get the number of student ticket sales.
x + y = 375
4.50x + 7.50y = 2212.50
Multiply equation(i) by 4.50x
4.50x + 4.50y = 1687.5
4.50x + 7.50y = 2212.50
3y = 525
y = 525 / 3
y = 175
x + y = 375
x = 375 - 175
x = 200
