The dimensions of a rectangular prism are shown below. Length 1 1/3 feet Width 1 foot length 2 1/3 feet. The lengths of the side

zysi [14]

Answer:

84 cubes

Step-by-step explanation:

Given,

The dimension of the rectangular prism are,

$1\frac{1}{3}\text{ ft }\times 1\text{ ft }\times 2\frac{1}{3}\text{ ft }$

Hence, the volume of the prism,

$V=1\frac{1}{3}\times 1\times 2\frac{1}{3}$

$=\frac{4}{3}\times \frac{7}{3}$

$=\frac{28}{9}\text{ cube ft}$

Now, the volume of a cube = side³,

If side = $\frac{1}{3}$ ft,

Then the volume of each cube,

$V'=(\frac{1}{3})^3=\frac{1}{27}\text{ cube ft}$

Hence, the number of cubes that can be packet in the prism

$=\frac{V}{V'}$

$=\frac{28/9}{1/27}$

$=\frac{27\times 28}{9}$

$=3\times 28$

$=84$

TV studio has brought in 9 boy kittens and 6 girl kittens for a cat food commercial. The director is going to choose 9 of these

Amanda [17]

Answer:

probability = 0.2517

Step-by-step explanation:

given data

boy kittens = 9

girl kittens = 6

choose kittens at random = 9

solution

total kitten are = 9 + 6 = 15

first we get here total no of probability that is

n(s) = 15 C 9

n(s) = $\frac{15!}{9!(15-9)!}$

n(s) =5005

and

total way to chose 5 boy kittens is = 9 C 3

n(3) = $\frac{9!}{3!(9-3)!}$

n(3) = 84

and

total way to chose 4 girl kittens is = 6 C 4

n(4) = $\frac{6!}{4!(6-4)!}$

n(4) = 15

total way to chose 5 boy kittens and 4 girl kittens is

total way = 84 ×15 = 1260

so probability that the director chooses 5 boy kittens and 4 girl kittens is

probability = $\frac{1260}{5005}$

probability = 0.2517
