24-7 Video Games takes a random survey of 500 site users and determines that the mean age of the sample is 18. Which conclusion is valid based on the random survey? A) Most users on all video game sites are exactly 18 years of age. B) Most users on the 24-7 Video Games site are about 18 years of age. C) Most users on the 24-7 Video Games site are 18 years of age or older. D) All users on the 24-7 Video Games site are 18 years of age or younger.

B

Step-by-step explanation:

Mean means average. So if you have a bunch of people around 18 years old, then your average will be 18. Hope this helps!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
