The expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle whose side lengths measures are (2x+2) ft, (x+3) ft, and n ft.
If we take the first two sides are (2x+2) ft, (x+3) ft, and third is n ft.
By the triangle property, that sum of the two sides is always greater than the third side.
2x+2+x+3 > n
3x+5 > n .....(1)
Now take first two sides as n ft, (x+3) ft, and third side (2x+2) ft
n+x+3 > 2x+2
n > x-1 .....(2)
From the inequality (1) and (2), we get:
x – 1 < n < 3x + 5
Thus, the expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.

At a restaurant, 42 people had breakfast on Saturday morning.
1/7• of the people ate eggs only.
2/3 • of the people ate both pancakes and eggs.
• The remaining people ate pancakes only.
Which fraction represents the number of people who ate pancakes only?
Answer:
17/21
Step-by-step explanation:
The amount of people that ate eggs only are:
42* 1/7 = 6
The amount of people that ate both pancakes and eggs are:
42 * 2/3 = 28
That means 34 people ate pancakes only.
The fraction that represents this is 34/42 = 17/21

solve for x - 10 = x-7 / 3
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...

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.
[tex]3(x-10)= \frac{x-7}{3} *3[/tex][tex]3x - 30 = x - 7[/tex]Step 2: Subtract x from both sides.
[tex]3x-30-x=x-7-x[/tex] [tex]2x-30=-7[/tex]Step 3: Add 30 to both sides.
[tex]2x-30+30=-7+30[/tex] [tex]2x=23[/tex]Step 4: Divide both sides by 2.
[tex]2x/2 = 23/2[/tex] [tex]x = 23/2 = 11.5[/tex]Therefore, x = 23/2 or 11.5.

Describe fully the single transformation that takes shape P to shape Q
I cant get the last mark
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.

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.

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?
A. All the boys in the cafeteria
B. All the students on his soccer team
C. Every 5th person entering the school
D. Every 5th person entering Daniella's Pizzeria
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:
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 ✔️

Netflix is considering a new romcom (romantic comedy) series. Before making a final decision, the producers design an experiment to estimate the proportion of viewers who would watch the series. A random sample of 1,040 viewers was selected and asked to watch the first two episodes. After viewing the episodes, 650 viewers indicated they would watch the new series. (Use t Distribution Table & z Distribution Table. ) (Round your answers to 3 decimal places. )
Required:
a. Estimate the value of the population proportion of people who would watch the new series.
b. Develop a 99% confidence interval for the population proportion of people who would watch the new series.
Using the z-distribution, as we are working with a proportion, it is found that:
a) The population proportion is of 0.625.
b) The interval is (0.586, 0.664).
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
The sample size and the population proportion are given, respectively, by:
[tex]n = 1040, \pi = \frac{650}{1040} = 0.625[/tex]
Hence, the bounds of the interval are given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 - 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.586[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 + 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.664[/tex]
