Answer:

28,716^3

Step-by-step explanation:

From the given, we need to determine the volume of a sphere. The sphere has a radius of 19 cm.

Calculation,

Sphere Volume = 4/3 * PI * radius^3, is the equation.

Substituting the given values,

Radius = 9 inches, PI = 3.14

volume = 4/3 * 3.14 * 19^3

volume = 28,716.34667 ^3

Therefore, the nearest centimeter is 28,716^3

Answer:

Sphere Volume = (4/3) * PI * radius^3

Volume = (4/3) * PI * 19^3

Volume = 28,730.9120146298

Volume = 28,731 (when using PI = 3.14159265...

Volume = 28,716.3466666667

Volume = 28,716 cc answer is A.

The measurement of the side of a RV is 469 inches the actual length is 480 inches what is the percent error

Ksivusya [100]

Answer:

Step-by-step explanation:

error in measurement = 480 - 469 = 11 inches

Percent error = error *100/actual length

= 11 * 100 /480 = 2.9%

If y varies directly with x and y=100 when x=5, what is the value of k?

horrorfan [7]

When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,

y=kx

Plug in (5,100)

100=k(5)

K=20

Suppose that two openings on an appellate court bench are to be filled from current municipal court judges. The municipal court

Ksju [112]

Answer:

$(a)\dfrac{92}{117}$

$(b)\dfrac{8}{39}$

$(c)\dfrac{25}{117}$

Step-by-step explanation:

Number of Men, n(M)=24

Number of Women, n(W)=3

Total Sample, n(S)=24+3=27

Since you cannot appoint the same person twice, the probabilities are <u>without replacement.</u>

(a)Probability that both appointees are men.

$P(MM)=\dfrac{24}{27}X \dfrac{23}{26}=\dfrac{552}{702}\\=\dfrac{92}{117}$

(b)Probability that one man and one woman are appointed.

To find the probability that one man and one woman are appointed, this could happen in two ways.

A man is appointed first and a woman is appointed next.
A woman is appointed first and a man is appointed next.

P(One man and one woman are appointed) $=P(MW)+P(WM)$

$=(\dfrac{24}{27}X \dfrac{3}{26})+(\dfrac{3}{27}X \dfrac{24}{26})\\=\dfrac{72}{702}+\dfrac{72}{702}\\=\dfrac{144}{702}\\=\dfrac{8}{39}$

(c)Probability that at least one woman is appointed.

The probability that at least one woman is appointed can occur in three ways.

A man is appointed first and a woman is appointed next.
A woman is appointed first and a man is appointed next.
Two women are appointed

P(at least one woman is appointed) $=P(MW)+P(WM)+P(WW)$

$P(WW)=\dfrac{3}{27}X \dfrac{2}{26}=\dfrac{6}{702}$

In Part B, $P(MW)+P(WM)=\frac{8}{39}$

Therefore:

$P(MW)+P(WM)+P(WW)=\dfrac{8}{39}+\dfrac{6}{702}\\$P(at least one woman is appointed)=\dfrac{25}{117}$
