Nine dolls are sold at an auction. The selling price, in dollars, of each of the 9 dolls sold is shown in the data set below. 22, 28, 30, 30, 32, 35, 75, 110, 525

Which statement best describes the selling prices and the most appropriate measure of center of the selling prices?

Practice
A
The selling prices are mostly clustered, making mean the most appropriate measure of center.

B
The most common selling price is at the center of a cluster, making mode the most appropriate measure of center.

C
The selling prices are skewed to the right and include an outlier, making mean the most appropriate measure of center.

D
The selling prices are skewed to the right and include an outlier, making median the most appropriate measure of center.

a negative exponent is translated as follows:

so, we have

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
