Which of the following exponential functions goes through the points (1, 12) and (2, 36)?
Savatey [412]

Answer:

The function through which given point passes is f(x) = 24 x - 12 .

Step-by-step explanation:

Given as :

The points are

x_1 , y_1 = 1 , 12

x_2 , y_2 = 2 , 36

now, slope of the line

Let The slope of line = m = \frac{y_2-y_1}{x_2-x_1}

Or, m = \frac{36 - 12}{2-1}

Or, m = 24

So The slope of line = m = 24

<u>Now, equation of line in point-slope form</u>

y - y_1 = m × (x - x_1 )

Or, y - 12 = 24 × (x - 1 )

or, y - 12 = 24 x - 24

or, y = 24 x - 24 + 12

or, y = 24 x - 12

or , f(x) = 24 x - 12

So, The function through which given point passes is f(x) = 24 x - 12 . Answer

rjkz [21]

Solution: The correct option is d. 8.75

<u>Explanation:</u>

The formula for variance is:

Variance =\frac{\sum(x-\bar{x})^{2}}{n}

First we need to find the mean \bar{x} of the given data:

\bar{x}=\frac{2+4+6+0+1+10+9+0+6+3+6+8+5+4+6+2}{16}=\frac{72}{16} =4.5

Now let's find \sum(x-\bar{x})^{2}, please have a look at the attached picture:

\therefore Variance = \frac{140}{16}=8.75
