From the figure, the dilation constant from ΔABC to ΔDEF is
QD/QA = 8/4 = 2

Test QB = QE:
We should have
QB = (1/2) QE
The statement is incorrect.

Test QC = CF:
We should have
QC = (1/2) QF, or QC = CF
The statement is correct.

Test DE = 2AB:
We should have
AB = (1/2)DE, or 2AB = DE.
The statement is correct.

Test AC = EF:
We should have
AC = (1/2)DF
The statement is incorrect.

We should also have
BC = (1/2)EF
Therefore, if BC = 2.25, then
EF = 2*BC = 2*2.25 = 4.5.

Answer:
QC = CF
DE = 2AB
EF = 4.50

Leona [35]

The correct answer is F. Quantitative data are numerical in​ nature, while qualitative data are categorical in nature.

Explanation:

In research and all the different fields that apply to it, the word "data" refers to information, values or knowledge that can be used to understand a specific situation or phenomenon. Additionally, data can be of two different types quantitative and qualitative, these differ in their nature, the phenomenons they described and the way they should be analyzed. Indeed quantitative data refers mainly to numerical data or information about quantities such as statistics that are especially useful in mathematics, science and similar that focus on numbers. On the other hand, qualitative data refers to data based on categories or qualities and because of this qualitative data is used in humanistic research, although both types of data can be combined to study a phenomenon. Considering this, the key difference between both types of data is "Quantitative data are numerical in​ nature, while qualitative data are categorical in nature".

balu736 [363]
There as 16 cards, 2 of which are wildlife cards, so the ratio is 16 : 2. We can simplify it by dividing both sides by 2, so we'll get the ratio of 8 : 1.

I hope this helps! :)

Answer: 64 miles

Step-by-step explanation:

Subtract all of Buck's expenses from the total amount that he spent to isolate the amount of miles.

70.23 (Total) - 39.95 (Flat Rate) - 9.80 (Gas) = 20.48

20.48  ÷ 0.32 (Cost Per Mile) = 64 (Total miles)
