Answer: Our required probability is 0.99338.

Step-by-step explanation:

Since we have given that

n = 100

p = 0.200

So, $np=100\times 0.2=20>5$

So, we can apply normal approximation.

Mean = 20

Standard deviation = $\sqrt{npq}=\sqrt{100\times 0.2\times 0.8}=\sqrt{16}=4=\sigma$

Since $z=\dfrac{\bar{X}-\mu}{\sigma}$

So, Probability that fewer than 30 but a packet after testing a free sample is given by

$P(X$

Hence, our required probability is 0.99338.

Please help me with this problem.

Tpy6a [65]

Answer:

5.6 meters

Step-by-step explanation:

V = pi r^2 h

We want to solve for h

Divide each side by pi r^2

V/ pi r^2 = pi r^2 h/ pi r^2

V/ pi r^2 =h

We know v = 440 pi = 22/7 and r = 5

440 / ( 22/7 * 5^2) = h

440 / (22*25/7) = h

440*7/550 = h

5.6 = h
