Rectangle LMNO is reflected over the x-axis to create rectangle L'M'N'O'. If a line segment is drawn from point M to point M', which statement would best describe the relationship between segment M M prime and the x-axis?

They are diameters of concentric circles.
They share the same midpoints.
They are perpendicular to each other.
They share the same endpoints.

Step-by-step explanation:

The transfomation is a reflection across the x-axis, which is defined

Notice that this transformation is about changing each vertical coordinate to its opposite, but the absolute value of each one is the same. This means each coordinate is in the same vertical.

Therefore, the line segment MM' is perpendicular to x-axis, because M and M' are in the same vertical.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
