Ryan is correct, the mean is about 8.1.

To find the mean, you have to add up all the values, then divide by the total amount.

For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050

If you add up all the adults, you have 500.

Dividing 4050 by 500 = 8.1

Sample B will produce a very similar result.

5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out

julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

$5\frac{1}{3}+x=2\frac{1}{2}$

$=\frac{16}{3} +x=\frac{5}{2}$

Subtracting both sides from 16/3 we get:

$x=\frac{5}{2}- \frac{16}{3}$

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

$x=\frac{5\times 3-16\times 2}{6}$

$x=\frac{15-32}{6}$

$x=\frac{-17}{6}$

Therefore, the answer is x = -17/6.
