Easy question.

So, the slope is -x and the y-intercept is at -4.

y = -x - 4

Use this equation and you will find:

y = -2 - 4

y = -6

Answer:

$g^{-1}x = \frac{1-2x}{x}$

Step-by-step explanation:

Given the function $g(x)= \frac{1}{x+2}$ , we are to find the inverse of the function and this can be done y following the simple steps:

Step 1: Replace y with $g(x)$

$g(x)= \frac{1}{x+2}\\y= \frac{1}{x+2}$

Step 2: Interchange x with y

$x= \frac{1}{y+2}$

Step 3: Make y the subject of the formula;

$x= \frac{1}{y+2}\\y+2 = \frac{1}{x}\\y = \frac{1}{x} - 2\\Find \ the\ LCM\\y = \frac{1-2x}{x}$

Step 4: Replace y as $g^{-1}(x)$

$g^{-1}x = \frac{1-2x}{x}$

Hence the inverse of the function is $g^{-1}x = \frac{1-2x}{x}$

Find the standard deviation for the given sample data. Round your answer to one more decimal place than is present in the origin

Tema [17]

Answer:

s = 19.7

Step-by-step explanation:

First we need to calculate the mean x' of the sample as:

$x'=\frac{55+18+39+20+20+44+69}{7}=37.9$

We sum all the scores and divide them by the number of scores.

Then, the standard deviation s is calculated as:

$s=\sqrt{\frac{(55-37.9)^2+(18-37.9)^2+(39-37.9)^2+(20-37.9)^2+(20-37.9)^2+(44-37.9)^2+(69-37.9)^2}{7-1} }\\ s=19.7$

We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.

So, the standard deviation of the sample is 19.7
