Bas_tet [7]

Volume of a cube with side lengths of 2, 2, and 2.
2³=8 m³

Volume of a cube with 4,4, and 4
4³=64 m³

Conclusion: The volume would be squared, or square rooted, depending on which way you are going.

Points showing equivalent relics on the coordinate planeten

koban [17]

Answer:

<em>Answer: (8,12) Third option</em>

Step-by-step explanation:

<u>Equivalent Ratios</u>

Nardia plotted some points showing equivalent ratios. The points shown in the graph are: (2,3), (4,6), (10,15)

The ratios of the points in the form y:x are:

$\frac{3}{2}$

$\frac{6}{4}=\frac{3}{2}$

$\frac{15}{10}=\frac{3}{2}$

Note all the ratios are equivalent.

From the ordered pairs provided in the choices, only one of them has the same ratio y:x.

Point (12,8) has a ratio:

$\frac{12}{8}=\frac{3}{2}$

Answer: (8,12) Third option

A pharmacist receives a shipment of 22 bottles of a drug and has 3 of the bottles tested. If 5 of the 22 bottles are contaminate

Norma-Jean [14]

Answer:

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.

Step-by-step explanation:

$C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

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

In this problem, we have that:

Total number of combinations:

$C_{22,3} = \frac{22!}{3!(18)!} = 1540$

Desired combinations:

It is 1 one 5(contamined) and 2 of 17(non contamined). So:

$C_{5,1}*C_{17,2} = 5*17*8 = 680$

What is the probability that exactly 1 of the tested bottles is contaminated?

$P = \frac{680}{1540} = 0.4416$

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
