The volume of a storage pod that is shaped like a cube is 1728 cubic feet what is the surface area of the storage pod?

Fittoniya [83]

Answer:

864

Step-by-step explanation:

since the volume is 1728, the cube root of 1728 is the length of each side, which is 12. to find surface area of a cube, we find the area of one face and multiply it by 6. 12*12*6 = 864.

(a) Count the number of ways to select a sample of 3 people to serve on a board of directors from a population of 6 people. answ

kodGreya [7K]

Answer:

a) 20

b) Equally likely, 0.05

Step-by-step explanation:

We are given the following in the question:

Population size, n = 6

Sample size, r = 3

a) Ways to select a sample of 3 from a population of 6

$= n^C_r\\=^6C_3\\\\=\dfrac{6!}{3!(6-3)!}\\\\=\dfrac{6!}{3!3!}\\\\=20$

Thus, there are 20 ways in which a sample of 3 can be selected from a population of 6.

b) The chances that any particular sample will be the one selected are equally likely.

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of selecting one particular sample =

$\text{P(Sample)} = \dfrac{1}{20} = 0.05$

Thus, 0.05 is the equally likely probability of selecting one sample.
