Answer:

The correct option is b.

Step-by-step explanation:

The given expression is

\frac{-9x^{-1}y^{-9}}{-15x^5y^{-3}}

It can be written as

\frac{-9}{-15}\times \frac{x^{-1}}{x^5}\times \frac{y^{-9}}{y^{-3}}

Using the property of exponent we get

\frac{3}{5}\times x^{-1-5}\times y^{-9+3}       [\because \frac{x^m}{x^n}=x^{m-n}]

\frac{3}{5}\times x^{-6}\times y^{-6}

\frac{3}{5}\times \frac{1}{x^{6}}\times \frac{1}{y^{6}}       [\because \frac{1}{x^n}=x^{-n}]

\frac{3}{5x^{6}y^{6}}

Therefore the correct option is b.

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?
Xelga [282]

Answer:

Option (3) is correct.

side length of square is (3x + 13 ) units.

Step-by-step explanation:

For a square with side 'a'. Perimeter is defined as the sum of length of side. Since, Square has four sides. Thus Perimeter of square = 4 × side

Given square has perimeter = 12x + 52

Comparing both sides,

4 × side = 12 x +  52

⇒ Side = \frac{12x+52}{4}

⇒ Side = \frac{4(3x+13)}{4}

⇒ Side = 3x + 13

Thus, side length of square is (3x + 13 ) units.

Thus, option (3) is correct.

Yuri [45]

Answer:

D. n1 and n2 can be of different sizes

Step-by-step explanation:

When we are trying to develop interval estimate for difference between two populations, we first select two samples from these populations. We get the interval using the required statistic.

These are:

- Sample size of both populations. Which are n1 and n2 respectively.

- then the Sample mean of two populations

- sample standard deviation.

The samples of different sample sizes can be used and we are not obligated to make use of the same sample size.
