A box has dimensions of 4.1 inches, 5.9 inches, and 7.2 inches. Estimate the volume of the solid.

1 answer:

7 0

4.1 ≈ 4 inches (tenth place is less than 5, round down)
5.9 ≈ 6 inches (tenth place is more than 5, round up)
7.2 ≈ 7 inches (tenth place is less than 5, round down)

Volume = 4 x 6 x 7

Volume = 168 in³ (Answer C)

Unknown to a medical researcher, 6 out of 25 patients have a heart problem that will result in death if they receive the test dr

Fiesta28 [93]

Using the hypergeometric distribution, it is found that there is a 0.0002 = 0.02% probability that exactly 6 patients will die.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

The values of the parameters for this problem are:

N = 25, k = 6, n = 8.

The probability that exactly 6 patients will die is P(X = 6), hence:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = 6) = h(6,25,8,6) = \frac{C_{6,6}C_{19,2}}{C_{25,8}} = 0.0002$

0.0002 = 0.02% probability that exactly 6 patients will die.

10 = k + 3 + 6k<br> How do I solve this equation?

Kaylis [27]

Answer:

k = 1

Step-by-step explanation:

$10=k+3+6k\\\\10=k+6k+3\\\\10=7k+3\\\\10-3=7k+3-3\\\\7=7k\\\\\frac{7=7k}{7}\\\\\boxed{1=k}$

Hope this helps.
