Answer:

$\frac{1}{6}-1\frac{1}{4}x$

Step-by-step explanation:

Given $(\frac{3}{4}x-\frac{2}{3})-(-\frac{5}{6}+2x)$

#We can evaluate by removing brackets and grouping the like terms:

$=(\frac{3}{4}x-\frac{2}{3})-(-\frac{5}{6}+2x)\\\\=\frac{3}{4}x-\frac{2}{3}+\frac{5}{6}-2x\\\\=\frac{1}{6}-1\frac{1}{4}x$

Hence, the given problem can be solved to it's simplest form as $\frac{1}{6}-1\frac{1}{4}x$

Simplify the expression. 12x^-6 y^10 times 3x^7 y

Vlada [557]

We need to simplify the expression:

$12x^{-6}y^{10} \times (3x^{7}y)$

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,

$12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)$

On simplifying the above expression we get:

$36\times x^{(-6+7)}\times y^{(10+1)}$

$=36 \times x^{1}\times y^{11}$

$=36 \times x \times y^{11}$

$=36xy^{11}$

So the simplified form of the expression $12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}$ .

The mean is usually the preferred measure of central tendency, but there are specific situations in which it is impossible to co

sergey [27]

Answer: a. It is commonly referred to as the arithmetic average.

b. It is algebraically defined (that is, there is an equation you can use to calculate its value).

c. It is easily influenced by extreme scores.

Step-by-step explanation:

The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.

It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.
