Someone PLZ ANSWER QUICK PLZ !! :)

Verizon [17]

Answer: Option c.

Step-by-step explanation:

To find surface area, add two area of circle and curved surface area.

Curved surface area formula = 2*π*r*h, where r = radius, h = height.

So total surface area will be,

2π*r ^ 2 + 2*π*r*h

Remember that radius(r) = 4 because diameter is given in figure.

What are the zeros of the polynomial function f(x)=x^3+2x^2-24x?

Verdich [7]

Immediately, we can factor an x out of each term to simplify the polynomial.

x(x^2 + 2x - 24)

In doing this, we know the first zero will be x = 0.

Using the AC method, we can find the next two zeros.

x(x - 4)(x + 6)

<h3>The zeros, or x-intercepts of the polynomial, are 0, 4, and -6.</h3>

Forty-nine cities provided information on vacancy rates (in percent) for local apartments in the following frequency distributio

Nostrana [21]

Answer:

$E(X) = \frac{431.5}{49}= 8.81$

$s^2 = \frac{4780.25- \frac{(431.5)^2}{49}}{48} = 20.425$

$s= \sqrt{20.425}= 4.52$

Step-by-step explanation:

For this case we can calculate all the questions with the following table:

Class Midpoint(Xi) fi Xi*fi Xi^2 *fi

____________________________________

0-3 1.5 6 9 13.5

3-6 4.5 6 27 121.5

6-9 7.5 11 82.5 618.75

9-12 10.5 21 220.5 2315.25

12-25 18.5 5 18 1711.25

_____________________________________

Total 49 431.5 4780.25

We can calculate the expected value with the following formula:

$E(X) = \frac{\sum_{i=1}^n X_i P(X_i)}{n}$

And if we replace we got:

$E(X) = \frac{431.5}{49}= 8.81$

We can calculate the sample variance with the following formula:

$s^2 =\frac{\sum X^2 f -\frac{(\sum xf)^2}{n} }{n-1}$

And replacing we got:

$s^2 = \frac{4780.25- \frac{(431.5)^2}{49}}{48} = 20.425$

And the deviation would be just the square root of the variance like this:

$s= \sqrt{20.425}= 4.52$
