The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.1

Answer:

0.6 probability that $-2 \leq x \leq 2$

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

$P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)$

From the table:

$P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11$ . So

$P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60$

0.6 probability that $-2 \leq x \leq 2$

Find the surface area of the pyramid round to the nearest tenth choose the correct unit

sineoko [7]

slant height(h) = 16.3ft

Base side = 20ft

$\text{Area of pyramid=}\frac{1}{2\text{ }}\times perimeterofbase\text{ x slant height}$

Perimeter of base = 4(base side) = 4(20) = 80ft

$\begin{gathered} \text{Area of pyramid = }\frac{1}{2}\times80\times16.3 \\ \text{Area = }652ft^2 \end{gathered}$

What is the range of the function graphed below?<br> ABCD

AlexFokin [52]

Answer:

(-4 , 0] ∪ (2, ∞)

Last option

Step-by-step explanation:

Since range is included 2 so (2, ∞) and other line is not included 0 but included -4 so it should be (-4, 0]

So range would be:

(-4 , 0] ∪ (2, ∞)
