Answer:

Step-by-step explanation:

To find the x- intercept let y = 0, hence

cos( $\frac{x}{2}$ ) = 0

$\frac{x}{2}$ = $cos^{-1}$ (0 ) = $\frac{\pi }{2}$

multiply both sides by 2

x = π ← x- intercept

Why is the table not a probability distribution table?

jeyben [28]

Using probability distribution concepts, the correct option is:

C. the sum of the probabilities is not 1.00

In a probability distribution, the sum of all probabilities has to be equals to 1.

In this problem, the probabilities are: 0.25, 0.45, 0, 0.35.

Their sum is:

$0.25 + 0.45 + 0 + 0.35 = 1.05$

Since the sum is not 1, the correct option is:

C. the sum of the probabilities is not 1.00
