Solve for r 12r=36 pro

blsea [12.9K]

Answer:

r = 3.

Step-by-step explanation:

The equation means 12 x r = 36. Well to work this out we can do a reverse method using division. We're going to do 36 divided by 12. The answer to that is 3 so r = 3. Let's check it now! 12 x 3 = 36? That sounds correct to me so there's our answer.

Hope that helps. x

Click the score on the graph where you think the balancing point would be for this data.

Ulleksa [173]

Answer:

The balancing point is 23

Step-by-step explanation:

Given

The above graph

Required

Determine the balancing point

This simply means that we calculate the mean.

From the above graph, we have:

$\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}$

So, the mean is:

$\bar x = \frac{\sum fx}{\sum f}$

$\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}$

$\bar x = \frac{230}{10}$

$\bar x = 23$

Hence, the balancing point is 23
