C. D(1/2) (W XY Z)
the dilation factor is 1/2 because the new shape is half the size
3) $28 bc, 18+10= 1/3 of the money bc he already spent 2/3 so 28 is the answer
Original price =$25,000
Depreciation rate = 11%
Note that 1 - 0.11 = 0.89.
Value after 1 year = $25,000 (0.89) = $22,250
Value after 2 years = $22,250 (0.89) = $19,802.50
Answer: $19,802.50
Answer:

Step-by-step explanation:
is the number of minutes a student was allowed to spend on the exam
is the students score out of 100
The slope of the regression line is
The intercept is
The equation of the regression line is

To answer this, we will look at simple definitions of each term. From the definitions, it will be clear which one is correct.
<u>What is mode?</u>
It is the most occurring number.
<u>What is interquartile range?</u>
It is the difference between third quartile and first quartile.
<u>What is range?</u>
It is largest number minus the smallest number.
<u>What is mean absolute deviation (MAD)?</u>
It is the average distance of each data point from the mean.
<u>What is a quartile?</u>
It is one of the four groups in which a dataset is divided.
From the simple definitions of each term, we can clearly see that Mean Absolute Deviation (MAD), answer choice D, is the correct answer.
Answer: Mean Absolute Deviation
