Dillon pays x dollars to get a haircut. He gives the stylist a 25% tip. The expression representing his total cost is
x + 0.25x

Which expression is equivalent and why?

A. 1.025x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.025.

B. 1.25x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.25.

C. 1.25x because adding $25 to the haircut is the same as
multiplying the cost by 1.25.

D. x(0.25) because the cost of the haircut can be factored out.

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.

Is the point (0, 8) on the x-axis or y-axis? how do you know?
