A bag contains tiles of different colors. Jackson randomly selects a tile from the bag and returns the tile to the bag after rec
quester [9]

Answer:

2/15

Step-by-step explanation:

The answer choices to this question do not make sense since probability is a measure that is always <= 1.0

Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles

Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45

Probability of drawing a green tile = 6/45 = 2/15

If f(x) and its inverse function, f(x), are both plotted on the same coordinate plane, where is their point of intersection?
Tcecarenko [31]

Answer:

(2,2)

Step-by-step explanation:

The graph of a function and that of its inverse should be always symmetric around the line y = x (goes at 45 degrees and crosses the origin of coordinates).

Therefore any intersection of the graphs must lie on the line y = x, which forces the x value of the intersection point to be the same as the y-value.

The only option shown where x and y have the same numerical value is the third listed option : (2,2)

Does a triangle with side lengths 7, StartRoot 80 EndRoot, and StartRoot 31 EndRoot from a right triangle?
AlladinOne [14]

Answer and Step-by-step explanation:

The sides we have are 7, \sqrt{80} , and \sqrt{31} .

The square root of 80 is less than 9 but greater than 8 (because 8^2 is 64, 9^2 is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.

So, \sqrt{80} is the longest side.

1) The square of \sqrt{80} is: (\sqrt{80} )^2=80

2) The sum of the squares of the two shorter sides is:

7^2+(\sqrt{31} )^2=49+31=80

3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.

Hope this helps!
