Answer:

55.6

Step-by-step explanation:

The mean is found by adding all the numbers together, and dividing by the amount of numbers there are. Note you must round to the tenths place.

(50 + 52 + 52 + 55 + 56 + 56 + 56 + 58 + 58 + 59 + 60)/11

First, combine and add all terms within the parenthesis, and then divide:

(612)/11 = 55.63... , or 55.6 (rounded to the nearest tenth place).

55.6 is your answer.

Find the product (8/6n-4)(9n^2-4)

Leokris [45]

Answer:

4(3n+2) or 12n+8

Step-by-step explanation:

Given expression is:

$(\frac{8}{6n-4})(9n^{2}-4)$

The numerator of the fraction will be multiplied with 9n^2- 4

So, Multiplication will give us:

$=\frac{8(9n^2-4)}{6n-4}$

We can simplify the expression before multiplication.

The numerator will be broken down using the formula:

$a^2 - b^2 = (a+b)(a-b)\\So,\\= \frac{8[(3n)^2 - (2)^2]}{6n-4}\\ = \frac{8(3n-2)(3n+2)}{6n-4}$

We can take 2 as common factor from denominator

$=\frac{8(3n-2)(3n+2)}{2(3n-2)}\\After\ cutting\\= 4(3n+2)$

Hence the product is 4(3n+2) or 12n+8 ..
