So,
To find the percent of SUV's out of the total number of cars, simply divide the number of SUV's by the total number of cars and simplify.

This equals 0.3.
Now, convert 0.3 to a percent by moving the decimal point two places to the right and adding a percent sign.
0.3 --> 30%
30% of the cars at the dealership were SUV's.
(-2)^3 * (-2)^(3*2)
(-2)^3 * (-2)^6
(-2)^(3+6)
(-2)^9
(x - 3)^2 = 0
(x - 3)(x - 3) = 0
x^2 - 3x - 3x + 9 = 0
x^2 - 6x + 9 = 0 <===
The stem-and-leaf plot for the distribution is given as follows:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
b) From the plot, the correct options are given as follows:
- A typical content is 32 calories per 100 ml.
- The distribution is roughly symmetric.
<h3>What is a stem-and-leaf plot?</h3>
The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:
4|5 = 45.
For this problem, the observations are given at the top in red, and using each <u>first digit as the key</u>, the stem and leaf plot is:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
The mean of these observations is:
(19 + 2 x 22 + 23 + 25 + 2 x 27 + 2 x 28 + 30 + 2 x 31 + 32 + 2 x 33 + 34 + 3 x 35 + 37 + 38 + 39 + 2 x 40 + 41 + 43)/26 = 32(approximately)
The correct statements from the plot are as follows:
- A typical content is 32 calories per 100 ml(due to the mean).
- The distribution is roughly symmetric(13 values below the mean, 13 at or above).
