Answer:
x 3:7 y 5:9 :)
Step-by-step explanation:
Perimeter of the rectangle:
2 L + 2 W = 30 cm
2 ( L + W ) = 30 cm
If the length and width of the rectangle is doubled in size the new perimeter would be:
2 ( 2 L + 2 W ) = 2 · 2 ( L + W ) = 2 · 30 cm = 60 cm
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
<h3>What is the random sample?</h3>
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.
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 to get your answer.
This is because there are 2 zeros in 100, so to cancel out the 2 zeros in 100, take out the 2 zeros in 1500 making it a lot easier.
