The standard deviation of a particular sample is equal to the standard deviation divided by the square root of the sample size.  That is,\sigma_x=\frac{\sigma}{\sqrt n}
The mean of a particular sample is equal to the mean of the set the sample was taken from.  That is,
\mu_x=\mu
\text{In your case, }\sigma_x=\frac{9}{\sqrt4}=\frac92\text{ and }\mu_x=45.

timmy writes the equation f(x) = x – 1. He then doubles both of the terms on the right side to create the equation g(x) = x – 2.
EleoNora [17]
<span>First, g(x) = 2x - 2, because when you double both of the terms of x - 1, you have to multiply each of the terms by two, i.e x * 2 = 2x and (-1) * 2 = - 2, so the result is 2x - 2. Comparing the graphs, you have that g(x) 's slope is 2, whils f(x) 's slope is 1, so that means that g(x) is more inclined or, what is the same, grows faster than f(x). Also, you can compare the y-intercepts, given that the y-intercept is the constant terms. So, the y-intercept of g(x) is -2, while the y-intercept of f(x) is - 1. </span>

Solve for x.<br> 18 = X/4 + 7
masha68 [24]
Multiply by 4 to get rid of fraction
4(18) = 4(x/4 + 7)
72 = x + 28
x = 44
Solution; x = 44

What is the equation of the exponential graph shown?
natta225 [31]

Answer:

100(0.5)^{x}

Step-by-step explanation:

According to the graph, the y int is at 100

so that is the starting point

Then at 1 it is at 50

\frac{100}{50} is 2 so that means it is reduced by half

Just to make sure, \frac{50}{25} is also /2 so that means it is the slope

Since it is a decay, the slope has to be less than one so you get the reciprecol of 2 to get....

\frac{1}{2}
