Answer:
The median is the best measure of center for distributions C and D.
Step-by-step explanation:
The <u>median</u> is the best measure of center for skewed distributions or distributions with outliers because it is a <u><em>robust</em></u> statistic, meaning that outliers and skewed data have <em>little effect </em>on the median.
Meanwhile, the <u>mean</u> is a good measure of center for symmetric distributions since it is <u><em>non-robust</em></u>.
Answer A has a roughly symmetric distribution, and answer B has a uniform distribution.
Answer C has a left-skewed distribution, and answer D seems to have a right-skewed distribution (since the right tail is longer than the left tail).
Therefore, the <u>median</u> would be the <u><em>best measure of center</em></u> for choices C and D.
Answer:
(7, 4)
Step-by-step explanation:
If point C is being translated to the right 2, the x coordinate will increase by 2. But, the y coordinate will stay the same.
Find the coordinates of C' by adding 2 to the original x coordinate:
5 + 2 = 7
The y coordinate will still be 4.
So, the coordinates of C' will be (7, 4)
Answer:

Answer:

Step-by-step explanation:
We are given the following equation:

We have to convert it into polar form.
We put

Putting values, we get:

is the required polar form.
Answer:
Step-by-step explanation:
To get the new price of the car multiply the original price by the percent increase in decimal form +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.
hope that helps my man
