Answer:

\frac{15x^2}{7y}

Step-by-step explanation:

The given complex fraction is:

\frac{\frac{x+4x}{y}}{\frac{7}{3x}}

Upon solving, we get

=\frac{x+4x}{y}{\times}\frac{3x}{7}

=\frac{3x(x+4x)}{7y}

=\frac{3x(5x)}{7y}

=\frac{15x^2}{7y}

Thus, \frac{\frac{x+4x}{y}}{\frac{7}{3x}}=\frac{15x^2}{7y}

which is the required simplified form.

Answer:

B. f(-1)=6

C.  The domain of f(x) is the set {-2.-1,0,1,2,3,4,5,6}

Step-by-step explanation:

To find f(5) from the table means, the y-value that corresponds to x=5.

This value is 12.

This implies that:

f(5)=12

Also the y-value that corresponds to -1 is 6.

Hence f(-1)=6

The domain of f(x) are the set of all the x-values.

The domain is : {-2.-1,0,1,2,3,4,5,6}

The range for f(x) is the set of all the corresponding y-values.

From the table, the range is: {5,6,7,8,9,10,11,12,13}

3x + 3<br> X + 8<br> What is the perimeter of each polygon?
Ganezh [65]

Answer:

D. 60

Step-by-step explanation:

4(3x + 3) = 5(x + 8)       12(4) + 12         5(4) + 40

12x + 12 = 5x + 40        48 + 12               20 + 40

-5x          -5x                   60                        60

7x + 12 = 40

 -12        -12

7x = 28

x = 4

Mumz [18]

Answer:

The mean of the sampling distribution of sample proportions will be 0.2

Step-by-step explanation:

Central Limit Theorem for Proportions:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

20% of American adults ages 25 and older had never been married.

This means that p = 0.2

So the mean of the sampling distribution of sample proportions will be 0.2
