It could. If you turn it into an experiment. Let's say you take 100 students from each grade, and you ask them if they exercise. And then you wanna create a graph. And find out out of those students how many of them exercise and how many of them do not. Then turn it into a percent.

I hope this helps. If you have any further questions on this or any other questions just ask. I am here to help you, as needed.

not really because some kids at the school might exercise more than other kids, so it can't be really a statistical question.

hope i helped:)

2 parts compost, 6 parts potting soil for 10 kg of mix. How many kg of compost

likoan [24]

Answer:

Step-by-step explanation:

A proportion could be used.

With 2 parts of compost and 6 parts potting soil, you would end up with 8 total parts.

So it can be written as a ratio of compost to total mix, or $\frac{2}{8}$

The problem states 10 kg are needed in total, and the variable would be the amount of compost

As a ratio it would be $\frac{x}{10}$ .

Use the ratios to write a proportion.

$\frac{2}{8} = \frac{x}{10}$

Multiply both sides of the equation by 10

$\frac{20}{8} = x$

Convert to a decimal if desired.

$x=2.5$

Can someone please help me, Thanks - Alyssa T.

A=LW
192=(13+x)((9+x)
192=117+22x+x^2 (subtract 192 from both sides)
x^2+22x-75+0 (factor)
(x+25)(x-3)=0
so x=-25 or 3
Check work
since we are adding x it can only be the positive solution so x=3 so the new dimensions are:
L=13+3=16m
W=9+3=12
check: 16*12=192 so the answer is correct hope this helped

6X plus 3Y equals 3 3x minus Y equals four

Delvig [45]

Answer:

Step-by-step explanation:

6x + 3y = 3 simplify by dividing both sides by 3 2x + y = 1

3x - y = 4 the 1st equation has a positive y, the 2nd has a negative y. Use elimination

to reduce them down to a single variable equation:

2x + y = 1

3x - y = 4

________

5x = 5 solve

X = 1 substitute back in to one of the original equations to find y

3x - y = 4

3(1) - y = 4

- y = 1

y = -1 (1,-1)
