Answer:

1/20, 0.05, 5%

Step-by-step explanation:

There are 20 total possibilities, so you choosing one of them has a 1/20 chance. For example, If you had numbered the balloons, and you wanted to pick a red one with the number 3 on it, there would be a 1/20 chance. 1/20= 0.05, which also equals 5%

Hope this helps!

Tangent is a line that touches the circle at one point going infintiely in both directions

chord is a line that goes from one side of the circle to the other and stays inside the circle, an example would be the diameter which is the longest chord in the circle

secant is a line that goes through the circle at 2 points, it's like a chord but it extends outside the circle

the vertex of this parabola is at (5,5). when the x-value is 6, the y-value is -1. what is the coefficient of the squared in the
zlopas [31]

Answer: OPTION D.

Step-by-step explanation:

The vertex form of a quadratic function is:

y= a(x - h)^2 + k

Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.

We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.

Then  we can substitute values into  f (x) = a(x - h)^2 + k and solve for "a". This is:

-1= a(6- 5)^2 + 5\\\\-1=a+5\\\\-1-5=a\\\\a=-6
