If one side of a cube is 15m in length,find its volume

sergeinik [125]

Answer:

$V = 3375~m^{3}$

Step-by-step explanation:

The formula of the volume of a cube is $V = a^{3}$ where "a" would correspond to the length of an edge/side/height/etc.

If we insert our value into the formula, we get the following result:

$V = a^{3}$

$V = 15m^{3}$

$V = 3375~m^{3}~(cubic~meters)$

A lottery has 60 numbers. To win the jackpot one needs to match all 7 numbers that are drawn by the machine. Is this a PERMUTATI

Vadim26 [7]

Answer: Hence, our required probability is $\dfrac{1}{386206920}$

Step-by-step explanation:

Since we have given that

Numbers in a lottery = 60

Numbers to win the jackpot = 7 numbers

We need to find the probability to hit the jackpot:

So, our required probability is given by

$P=\dfrac{^7C_7}{^{60}C_7}\\\\P=\dfrac{1}{386206920}$

This is a combination problem as we need to select 7 numbers irrespective of any arrangements.

Hence, our required probability is [tex]\dfrac{1}{386206920}[/tex
