The statements that are true regarding the measures of center and variability of these data sets include:
A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
How to calculate the mean of any data set?In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:
Mean, \bar{x} = ∑x/n
Where:
∑x represents the sum of all data values.n represents the total number of data items.Based on the information provided, we have:
Mean of Yard Works = (7+9+7+12+5)/5
Mean of Yard Works = 8.
Mean of Grow Station = (9+11+6+12+7)/5
Mean of Grow Station = 9.
Range is the difference between the maximum and minimum numbers;
Range of Yard Works = 12 - 5
Range of Yard Works = 7.
Range of Grow Station = 12 - 6
Range of Grow Station = 6.
Mean absolute deviation is given by;
MAD = 1/n ∑|x - μ|
Where:
n represents the number of data (observed values)μ represents the mean of the data set.x represents the individual data (values)Mean absolute deviation of Yard Works = 2
Mean absolute deviation of Grow Station = 2.

Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.
Answer:
Step-by-step explanation:
If the dilated image is smaller than the original, then 0<k<1.
Meaning the scale factor is less than one, but greater than zero.
You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.
Let's choose [tex]\frac{1}2}[/tex].
In the original figure Point A = (-4,3) dilating by [tex]\frac{1}{2}[/tex] results in A' being (-2, 1.5). When you multiply each cooordinate (-4,3) by one half.
Applying the scale factor of one half to the other coordinates - yields these results.
Point B (4,3) becomes Point B' (2, 1.5)
Point C (-4,-4) becomes Point C' (-2,-2).
Point D (4, -4) becomes Point D' (2,-2)
Answer:
K will equal something more than 0 and less than 1.
Explanation:

So, if I have 30 slides to do, and seven days to do them, how many slides will I do each day?
Answer: Roughly 4.3 (You would want to do 5 a day, which will make you not need to work the seventh day, if the answer is even.)
Step-by-step explanation:
30 (slides) divided by 7 (days) = 4.28571... = round up to 4.3 or 5
Luis has $12 and wants to buy 6.6 pounds of apples. Apples cost $1.80 per pound. Luis rounded each value and estimated that he does not have enough money to cover the cost of the apples before sales tax is applied. Which best explains how his estimate relates to the actual product?
Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.
Because each value rounds up, his estimate is higher than the actual product. He does not have enough money to buy the apples.
Because each value rounds up, his estimate is lower than the actual product. He does not have enough money to buy the apples.
Because each value rounds up, his estimate is lower than the actual product. He might have enough money to buy the apples.
Answer:
A. Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.
Step-by-step explanation:
You want to know how Luis's estimate that $12 is not enough money to buy 6.6 pounds of apples at $1.80 per pound relates to the actual product. Luis rounded each value up.
EstimateBy rounding each value up before multiplying them, Luis arrived at a product that is higher than the actual product. This means ...
A. Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.

Additional comment
The actual product is 6.6×$1.80 = $11.88. Depending on the amount of tax, Luis may have enough money.

The electricity consumption in a start-up company was 4 kwh per day. As the manpower increased, the consumption of electricity increased to 10 kwh per day. What is the percent of increase in the consumption of electricity at the start-up company?
Answer:
150%
Step-by-step explanation:
10-4 is 6, and that is how much it increased by. Now, you have to find what percentage is 6 out of 4. 6/4 is 1.5, so you would multiply 1.5 by 100 to make it into a percent. 1.5*100=150, so your answer is 150%.

A company has recently been hiring new employees. Today the company has 32% more employees than it did a year ago. If there are currently 29,700 employees, how many employees did the company have a year ago?
the company a year ago had "x" employees, which oddly enough is the 100%.
now, today they have 32% more than that, well, 100% + 32% = 132%, and we know that's 29,700 employees
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 29700& 132 \end{array} \implies \cfrac{x}{29700}~~=~~\cfrac{100}{132} \\\\\\ \cfrac{ x }{ 29700 } ~~=~~ \cfrac{ 25 }{ 33 }\implies 33x=742500\implies x=\cfrac{742500}{33}\implies x=22500[/tex]
