Step-by-step explanation:

you need the circumference of the cirle aka perimeter of circle so 8(pi) and then because its only half, divided by 2... 12.56

now you hgave circumference so add 12.56 to 28 and there you go. you can round how ever necessary

Find the volume of the sphere with a radius, r, of 3/2 feet and π ≈ 3.14.

nalin [4]

Answer:

V= 14.13

Step-by-step explanation:

Information needed:

V= 4/3 $\pi$ r^3

$\pi$ = 3.14

r= 3/2

Solve:

V= 4/3 $\pi$ r^3

V= 4/3(3.14)(3/2)^3

V= 4/3(3.14)(27/8)

V= 14.13

Answer:

B. $\frac{6}{2x^{2} - 5x}$

Step-by-step explanation:

The product of the ratioal expressions given above can be found as follows:

$= \frac{2}{x} * \frac{3}{2x - 5}$

Multiply the denominators together, and the numerators together, separately to get a single expression

$\frac{2(3)}{x(2x - 5)}$

$= \frac{6}{x(2x) - x(5)}$

$= \frac{6}{2x^{2} - 5x}$

The product of the expression $\ = \frac{2}{x}*\frac{3}{2x - 5}$ = $\frac{6}{2x^{2} - 5x}$

The answer is B.

Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five event

Answer:

$P(x < 3) = 25\%$

$E(x) = 3$

Step-by-step explanation:

The given parameters can be represented as:

$\begin{array}{ccccccc}x & {5} & {4} & {3} & {2} & {1}& {0} & P(x) & {25\%} & {30\%} & {20\%} & {15\%} & {5\%} & {5\%} \ \end{array}$

Solving (a): P(x < 3)

This is calculated as:

$P(x < 3) = P(x = 0) + P(x = 1) + P(x =2)$ ----- i.e. all probabilities less than 3

So, we have:

$P(x < 3) = 5\% + 5\% + 15\%$

$P(x < 3) = 25\%$

Solving (b): Expected number of events

This is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

$E(x) = 5 * 25\% + 4 * 30\% + 3 * 20\% + 2 * 15\% + 1 * 5\% + 0 * 5\%$

$E(x) = 125\% + 120\% + 60\% + 30\% + 5\% + 0\%$

$E(x) = 340\%$

Express as decimal

$E(x) = 3.40$

Approximate to the nearest integer

$E(x) = 3$
