Which of the following valued of x is not in the domain of f(x) = x+3 / x-7

Mathematics

Answer:

x = 7 is not there in the domain of the function.

Step-by-step explanation:

The given function is f(x) = \frac{x+3}{x-7}

We have to find out which all values are not there in the domain of the function.For the function to become not defined the function should have infinite value and this happens when the denominator becomes zero.

In the given function for the denominator to become zero , the value of x must be 7.

For all other values of x , the function is defined.

Hence , the domain of x is all real numbers except 7.

The areas of two equilateral triangles are 27 yd2 and 75 yd2. Find the ratio of their perimeters.
Cloud [144]
If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25 

If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.

Which answer shows this equation written in standard form?
STatiana [176]
4-3(x-y)=-8x+2
=4-3x-3y=-8x+2
=4-3x+8x-3y-2
=5x-3y+2
or 
5x-3y=-2
so it will be C=5x+3y=-2

Factor -1/4 out of -1/2-5/4y
In-s [12.5K]
When we factor out something, we divide the factor by the equation. For example if we were to factor 3 out of 6, It will be 3(2). We got this answer by dividing 3 and 6. Using this concept:

\frac{-1}{4}[( \frac{-1}{2} / \frac{-1}{4}) - ( \frac{5}{4} y /  \frac{-1}{4})]

Simplifying:

\frac{-1}{4}(2 + 5y)

Hope this helps!

Suppose a team of doctors wanted to study the effect of different types of exercise on reducing body fat percentage in adult men
Inessa05 [86]

Answer:

<em>A. The F statistic increases as the differences among the sample means for the exercise groups increase.</em>

<em>C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.</em>

<em>F. The F statistic is 9.2242.</em>

Step-by-step explanation:

Given that

Observations                     Samples                             Total

40-49             10       11              9         9                        39

The degrees of freedom is given by

For numerator= k-1 = 4-1=3

For denominator= n-k= 39-4= 35

F statistic is given by

F= MS between/ MS within

=11.632991 / 1.261143 = 9.2242

Where

Mean Square Between = MS between = 11.632991

Mean Square Within = MS within = 1.261143

<u>Hence the correct choices are  A, C and F</u>

<em>A. The F statistic increases as the differences among the sample means for the exercise groups increase.</em>

<em>C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.</em>

<em>F. The F statistic is 9.2242.</em>

<em></em>

Suppose we have

Mean Square Between = MS between = 18.632991

Mean Square Within = MS within = 1.261143

Then F statistic would be = 14.77468 > 9.2242

which tells that <em>The F statistic increases as the differences among the sample means for the exercise groups increase.</em>
