C, every 5th student entering the school.

This would provide the least biased answer by the chances, it would not be skewed as my boy Gabe is asking random people that are spread out rather than simply everyone on his soccer team (if there is a connection between enjoying pizza and playing soccer) or asking everyone in the cafeteria, as similar people may sit together. It’s all in the chances.

Question:

Gabriel wants to know which pizzeria is most popular with students at his school. Which group of students should Gabriel survey in order to get the most accurate results?

Answer:

C. Every 5th person entering the school.

Step-by-step explanation:

A. All the boys in the cafeteria. This is incorrect because they would only add up to 1. The boys. And 2. Only the boys inside of the cafeteria. So that not even counting the ones that are still in the classrooms or in the bathrooms. so therefore A is incorrect.

B. All the students on his soccer team. This would not add up to much because lets say there are 10 players on his soccer team and over 100 people in his school, that would only make up 10% of his whole school, so obviously, B. Is also incorrect.

D. Every 5th person entering Daniella's Pizzeria. This is incorrect also because Gabriel wants to know which pizzeria is most popular in his school, this answer does not say anything about his school, it only says which pizzeria and how many people. In answer D. It says Every 5th person entering Daniella's Pizzeria. This answer already says which pizzeria he would be going to so that part is already proof that D is incorrect.

C. Every 5th person entering the school. This is correct beause it explains how he would be asking every 5th person entering the school. So lets say most of the people he tallied likes Daniella's Pizzeria the most. There would be a tally poll that I have shown in the picture. (Sorry that its messy I did that on mouse.) and as you see in green it says that more people like Daniella's Pizzeria more than any others. So now Gabriel has his results, so now he knows which pizzeria to go to.

Answer:

  dilation by a factor of 3 about (1, 0)

Step-by-step explanation:

You have correctly surmised that Q is a dilation of P by a factor of 3. The center of dilation is not the origin, so the trick is to figure out where it is.

__

An original point and its dilated image are always on the same line through the center of dilation. Here, that center can be found by drawing lines through the corresponding vertices. The attachment shows the center of dilation is (1, 0) on the x-axis.

The single transformation is ...

  dilation by a factor of 3 about the point (1, 0).

__

Additional comment

You can check this by seeing that each image point is 3 times as far from this center as the corresponding original point.

Answer:

B. the greatest common factor of 10 and 15 is 5.

Step-by-step explanation:

A. is worg 14 cannot be divided by 5

C. is wrong 13 cannot be divided by 3

D. is wroing 14 cannot be divided by 3

I mean they all can but you won't get the whole numbers only fractions.

Option B

Let's check each option one by one.

A) The greatest common factor of 10 and 14 is 5.

Write down the factors of 10 and 14.

⇒ Factors of 10: 1, 2, 5, 10

⇒ Factors of 14: 1, 2, 7, 14

We can see here that the GCF is "1" as it is the greatest factor of 10 and 14.

Hence, option A is incorrect.

B) The greatest common factor of 10 and 15 is 5.

Write down the factors of 10 and 15.

⇒ Factors of 10: 1, 2, 5, 10

⇒ Factors of 15: 1, 3, 5, 15

We can see here that the GCF is "5" as it is the greatest factor of 10 and 15.

Hence, option B is correct.

C) The greatest common factor of 13 and 21 is 3.

Write down the factors of 13 and 21.

⇒ Factors of 13: 1 and 13

⇒ Factors of 21: 1, 3, 7, 21

We can see here that the GCF is "1" as it is the greatest factor of 13 and 21.

Hence, option C is incorrect.

D) The greatest common factor of 14 and 21 is 3.

Write down the factors of 14 and 21.

⇒ Factors of 14: 1, 2, 7, 14

⇒ Factors of 21: 1, 3, 7, 21

We can see here that the GCF is "7" as it is the greatest factor of 14 and 21.

Hence, option D is incorrect.

Thus, Option B is correct.

Probably the answer:

Probably A. but I didn't read it and I just wanted to say this...

Step-by-step explanation:

I'll assume you meant f(x) = 3 - 2x and not t(x) = 3 - 2x

[tex] \frac{3 - 2x}{ \frac{1}{x + 5} } \times 8[/tex]

[tex]((3 - 2x) \times ( \frac{x + 5}{1} )) \times 8[/tex]

[tex]((3 - 2x)(x + 5)) \times 8[/tex]

[tex]( - 2 {x}^{2} - 7x + 15) \times 8[/tex]

[tex]( \frac{f}{g}) \times 8 = - 16 {x}^{2} - 56x + 120[/tex]

Adam's net income after a tax withholding will be 533 dollars. Then the correct option is B.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Adam makes $632 gross income per week and has claimed four allowances.

The weekly withholding is 99 dollars.

Adam's net income after a tax withholding will be

⇒ $632 - $99

⇒ $533

Answer:

7

Step-by-step explanation:

There are seven t's that equal 49. So do 49 divided by 7. Therefore, t = 7.

Hi!

In the picture, we can see that 7 of the t's are equal to 49. We can set this up using an equation:

[tex]7t=49[/tex]

Now, in order to solve for t, we must divide both sides by 7 to isolate the variable on one side of the equal sign:

[tex]\cfrac{7t}{7} =\cfrac{49}{7}[/tex]

Simplify:

[tex]t=7[/tex]

Therefore, t = 7 makes the equation true.

We can also check our work. On the scale, 7 t's are equal to 49, remember? So if there are 7 t's, and each t is equal to 7, we do 7 * 7 which is equal to 49.

49=49  ✔️

Answer: 23/2 or 11.5

Step-by-step explanation:

x - 10 = (x - 7) / 3

3 (x - 10) = x - 7

3x - 30 = x - 7

3x - x = 30 - 7

2x = 23

x = 23/2 answer...

change it into decimal form

x = 11.5 answer...

note: 23/2 or 11.5 both could be the answers

hope that helps...

Answer:

x = 23/2 or 11.5

Step-by-step explanation:

Step 1: Multiply both sides by 3.

Step 2: Subtract x from both sides.

Step 3: Add 30 to both sides.

Step 4: Divide both sides by 2.

Therefore, x = 23/2 or 11.5.

The probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091

The distribution of the marbles is given as:

White = 3

Yellow = 4

Green = 5

Total = 12

The probability of selecting a white marble is:

P(White) = 3/12

Now, there are 11 marbles left.

The probability of selecting a yellow marble is:

P(Yellow) = 4/11

The required probability is:

P = 3/12 * 4/11

Evaluate

P = 0.091

Hence, the probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091
