The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.

<h3>How to determine the fair game?</h3>

The number of sections in the spinner is given as:

n = 20

There are 10 numbers greater than 10 i.e. 11 to 2.

So, the probability that a number greater than 10 is spun is:

P = 10/20

P = 0.5

The probability that a number that is not greater than 10 is spun is calculated using the following complement rule

q = 1 - p

This gives

q = 1 - 0.5

Evaluate

q = 0.5

Notice that both probabilities are the equal

Hence, the spinner game that is fair is (b) If you spin a number greater than 10, you win.

I'm pretty sure to solve this all you do is subtract 77.95 - 75.65, which would be 2.30. Hope that helps!

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term i
otez555 [7]
Now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.

\bf \qquad \textit{parabola vertex form}\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\&#10;x=a(y-{{ k}})^2+{{ h}}&#10;\end{array} \qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\&#10;-------------------------------\\\\&#10;vertex&#10;\begin{cases}&#10;h=3\\&#10;k=5&#10;\end{cases}\implies y=a(x-3)^2+5&#10;\\\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;y=6\\&#10;x=-1&#10;\end{cases}\implies 6=a(-1-3)^2+5&#10;\\\\\\&#10;1=a(-4)^2\implies 1=16a\implies \cfrac{1}{16}=a
