The stem-and-leaf display shows the number of home runs hit by Mark during the 1986 - 1999 seasons. Describe the distribution, mentioning its shape and any unusual features. The key for the stem-and-leaf display is 7 vertical line 2 equals 727 2=72.

The distribution is symmetric

The distribution is skewed to the right

The distribution is skewed to the left

Step-by-step explanation:

Stem-and-leaf display can be plotted by the following steps:

(1)From the given data, the smallest and largest number must be identified

(2)Identity the stem. This is always the digit to the left of the right most digit. One digit number have a stem of 0. Consider the number 727 in the question, the stem is 2

The right-most digit of 727 is 7, and 2 is the left digit to it(7).

Also, for a number 27, stem is 2

Also for a number 2, stem is 0.

(3)Draw a vertical line and list the stem numbers to the left of the line

(4)Fill in the data given as leaves

(5)Sort the leaf data

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
