The mean of a data set is equal to the sum of the set of

numbers divided by how many numbers are in the set.

So to find the mean of the data set shown here,

let's begin by adding the numbers.

So we have .

This will be divided by how many numbers are in the set, which is 10.

So we have .

Adding the number, we get 176.

176 is divided by the number of numbers in the set or 10.

So we have .

176 divided by 10 is equal to 17.6.

So the mean of the set of data shown here is 17.6.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
