The following table shows the data collected from a random sample of 100 middle school students on the number of hours they do household chores every week:
Weekly Duration of Household Chores
Time (in hours) 0–1 2–3 4–5 6–7
Number of Students 32 64 3 1
There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to do household chores for at least two hours every week?
A: 480
B: 960
C: 1,020
D: 1,440
PLS DONT ANSWER WITH A LINK! :) My answer ended of being 1,020 but I dont think its right pls help
Answers
Answer:
1020 students
Step-by-step explanation:
the key word is at least, this means anything under that number will not qualify. So that leaves 68 out of the 100 sample students. So if you want to have the same thing but with 1,500 students. Take off the 2 zeros at the end of 1500 and multiply by 68 getting your answer. This is because there is 2 zeros in 100, so to cancel out the 2 zeros in 100, just take out the 2 zeros in 1500 making it a lot easier.
The students in the school would be expected to do household chores for at least two hours every week with 1020 students.
We have given
Time (in hours) 0– 1 2–3 4–5 6–7
Number of Students 32 64 3 1
What is the random sample?
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
The keyword is at least, this means anything under that number will not qualify.
So that leaves 68 out of the 100 sample students.

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

A circle has a diameter of 8. What is the area in terms of π?
I need the answer asap
Answers
Answer:
50.24²
Step-by-step explanation:
Okay, so the formula for the area of a circle is π x radius² and we're just going to use 3.14 for π so:
We first have to find the radius, the radius is half the diameter:
8 ÷ 2 = 4
So 4 is our radius
4² = 16
3.14 x 16 = 50.24
So, the area of the circle is 50.24²
hope this helps:)
Formulas:
A=pi r^2
D=2 r
When solving for A:
A=1/4pi d^2 = 1/4*pi*8^2 which is approximately 50.26548

-2-3a = -23
pls anwer with steps
Answers
Answer:
Step 1: Simplify both sides of the equation.
−2−3a=−23
−2+−3a=−23
−3a−2=−23
Step 2: Add 2 to both sides.
−3a−2+2=−23+2
−3a=−21
Step 3: Divide both sides by -3.
−3a−3=−21−3
a=7
-3a = -21
a = 7
Place the -2 beside the -23. When you switch sides the negative will change to positive. Then there will be -3a on one side. After you do -23+2 the answer will be -21. -21 divided by -3a will make a = 7
