The answer is C because if you put
![x = - 2 \\ y = 1 \\](https://tex.z-dn.net/?f=x%20%3D%20%20-%202%20%5C%5C%20y%20%3D%201%20%5C%5C%20)
Find the reflected two points which are:
![x = 1 \\ y = - 2](https://tex.z-dn.net/?f=x%20%3D%201%20%5C%5C%20y%20%3D%20%20-%202)

A bag contains 10 tiles with the letters A, B, C, D, E, F, G, H, I, and J. Five tiles are chosen, one at a time, and placed in a

I assume in this item, we are to find at which step is the mistake done for the calculation of the unknown probability.
For the possible number of arrangement of letter, n(S), the basic principles of counting should be used.
= 10 x 9 x 8 x 7 x 6 = 30,240
This is similar as to what was done in Meghan's work.
For the five tiles to spell out FACED, there is only one (1) possibility.
Therefore, the probability should be equal to 1/30,240 instead of the 1/252 which was presented in the steps above.
500 miles / 20 gallons = 25 miles / gallon
25 miles * 18.5 gallons = 462.5 miles / one tank of gas
Using the Heron's formula, the area of the triangle is: D. 95 square inches.
<h3>What is the Heron's Formula?</h3>
Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.
Given the following:
s = semi-perimeter = 1/2(50) = 25 in.
a = length of side a = 22 in.
b = length of side b = 13 in.
c = length of side c = 50 - 22 - 13 = 15 in.
Plug in the values
Area = √[25(25 - 22)(25 - 13)(25 - 15)]
Area = √[25(3)(12)(10)]
Area ≈ 95 square inches.
