Paper: 8
Answers
The number of students those who will most likely have their preference to do their classwork online is 238 out of 350
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
According to the question statement:
A teacher surveys a random group of students about their preference for doing classwork online or on paper.
17 preferred online and 8 preferred on paper.
To find the number of students who will most likely have their preference to do their classwork online:
We will apply the concept of probability.
Probability(Event) = Favorable Outcomes/Total Outcomes
For the survey,
probability of students preferring online mode of classwork is = 17 /(17+8)
= 17/25
= 0.68
Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68
Let m be the number of students preferring online mode of classwork.
m / 350 = 17/25
m / 350 = 0.68
m = 350 x 0.68
m = 238
Therefore, the number of students are 238.

Sarah’s mom took 3 hours to clean, but when Sarah helped, it took them 2 hours to clean. How many hours will it take Sarah to clean herself?
Answers
Answer:
It takes them 1.875 hours.
Step-by-step explanation:
Here, the job is cleaning the house.
Mom does 1 job in 3 hours.
In 1 hour, mom does 1/3 of the job.
Dad does 1 job in 5 hours.
In 1 hour, dad does 1/5 of the job.
Mom and dad working together do the job in x hours.
In 1 hour, mom and dad together do 1/x of the job.
1/3 + 1/5 = 1/x
5/15 + 3/15 = 1/x
8/15 = 1/x
8x = 15
x = 15/8 = 1.875
Answer: It takes them 1.875 hours.

The first step that we must take before attempting to solve the problem is to understand what the problem is asking us to do and what is given to us to help solve the problem. In this case, we are asked to solve for the area and we are provided with a figure that has 3 different corresponding lengths.
Moving onto the next step, we must determine what the area of the shape is. Looking at the shape, we can see as if there is a square and a triangle that have been glued together so we can find the area of each individual shape and add them up together to achieve the total area. Let us first determine the area of the square.
Area of the square
[tex]A_{square} = side^2[/tex][tex]A_{square} = (8\ yd)^2[/tex][tex]A_{square} = (8)^2 * (yd)^2[/tex][tex]A_{square} = 64\ yd^2[/tex]Now that we have the area of the square finished, we can move onto the next part and determine the area of the triangle.
Area of the triangle
[tex]A_{triangle} = \frac{height\ *\ base}{2}[/tex][tex]A_{triangle} = \frac{4\ yd\ *\ 8\ yd}{2}[/tex][tex]A_{triangle} = \frac{32\ yd^2}{2}[/tex][tex]A_{triangle} = 16\ yd^2[/tex]We have finally gotten the area for both the square and the triangle which means that we can add them together and determine the total area of the figure.
Total area of the figure
[tex]A_{figure} = A_{square} + A_{triangle}[/tex]
[tex]A_{figure} = 64\ yd^2 + 16\ yd^2[/tex]
[tex]A_{figure} = 80\ yd^2[/tex]
Therefore, after finding the area for both the triangle and square aspect of the figure we were able to combine them and get the total area of the figure which turned out to be 80 yards squared.

Basketball tickets were $5 for floor seats
$2 for the grandstand seats
I’d 210 people attended and paid $660, how many people bought floor seats?
Answers
130 people's bought floor seats ...
Explanation:→ First , we need to identify and define the unknown terms.
F: # of floor seats sold
G: # of grandstand seats sold
• F + G = 210 {210 is the total number of seats sold}
• 5F + 2G = 660 {the 5 , 2 and 660 refer to amounts of dollars} .
→ We now have two equations in two unknowns , which we should be able to solve.
→ Let's solve the first equation for G, and then substitute the value of G into the second equation , so that we have will have a single equation with only F as the unknown ...;
→ F represents the number for which we are looking: The number of floor seats sold.
Let's find numbers of people's bought floor seat:F + G = 210
F - F + G = 210 - F
G = 210 - P
→ 2F+ 5G = 660
→ 2F + 5(210 - F) = 660
→ 2F + 1050 - 5F = 660
→ - 3F + 1050 = 660
→ - 3F + 1050 - 1050 = 660 - 1050
→ - 3F = - 390
→ F = - 390 / - 3 = 130
→ F = 130
• Hence , 130 people's bought floor seats ...

Answer: ✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
Hello!
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
❖ Mean = 4.8 Median = 4.5
The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.8
To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:
4 + 5 = 9
9 ÷ 2 = 4.5
