16 % of tiles are black
<em><u>Solution:</u></em>
Given that floor tiles come in red, blue, and black
To find: percent of the tiles that are black
From given question,
number of red tiles = 16
number of blue tiles = 5
number of black tiles = 4
Therefore, total number of tiles = number of red tiles + number of blue tiles + number of black tiles
Thus total number of tiles = 25
<em><u>To percent of the tiles that are black, use the following formula:</u></em>
Thus 16 % of tiles are black
Answer:
Step-by-step explanation:
Given, A class has five boys and nine girls.
Total students = 5+9=14
Number of ways to choose 6 students out of 14= [Using combinations]
Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) =
If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-
hence, the required probability = .
First, We observe that the function is a parabola that grows
For this case, we must first graph the function to observe the behavior of the same.
We see that the vertex of the function is located at the point:
(x, y) = (- 2, -3)
The point is a minimum.
Answer:
(x, y) = (- 2, -3)
It is a minimum.
