Given that x is a hypergeometric random variable with Nequals10, nequals4, and requals6, complete parts a through d. a. Compu

sergey [27]

Answer:

a. 0.114

b. 0.005

c. 0.381

d. 0.00

Step-by-step explanation:

If x follows a hypergeometric distribution, the probability that x is equal to k is calculated as:

$P(x=k)=\frac{(rCk)*((N-r)C(n-k))}{NCn}$

Where k≤r and n-k≤N-r, Additionally:

$aCb=\frac{a!}{b!(a-b)!}$

So, replacing N by 10, n by 4 and r by 6, we get:

$P(x=k)=\frac{6Ck*((10-6)C(4-k))}{10C4}=\frac{6Ck*(4C(4-k))}{10C4}$

Then, the probability that x is equal to 1, P(x=1) is:

$P(x=1)=\frac{6C1*4C3}{10C4}=0.114$

The probability that x is equal to 0, P(x=0) is:

$P(x=0)=\frac{6C0*4C4}{10C4}=0.005$

The probability that x is equal to 3, P(x=3) is:

$P(x=3)=\frac{6C3*4C1}{10C4}=0.381$

Finally, in this case, x can take values from 0 to 4, so the probability that x is greater or equals to 5 is zero.

Answer:

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3

Step-by-step explanation:

Volume of cone

V_cone = (1/3)*( $\pi$ *(radius^2))*h

radius = 2ft

h = height of the cone = 3 ft

pi = 3.1416

V_cone = 4 $\pi$ ft^3

Volume cylinder

V_cylin = ( $\pi$ *(radius^2))*h_cyl

h_cyl = height of the cylinder = 10 ft

V_cylin = 40 $\pi$ ft^3

Volume rocket

V_rocket = V_cone + V_cylin = 4 $\pi$ ft^3 + 40 $\pi$ ft^3

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3
