Deshawn has two bags of marbles. The first bag has 2 blue, 3 orange, and 5 red. The second bag has 4 pink, 10 blue, and 6 brown.

madreJ [45]

Answer: 0.1

Step-by-step explanation:

Given

Bag-I has 2 blue,3 orange, 5 red

Bag-II has 4 Pink,10 blue, 6 brown

No of ways of choosing a blue marble from bag-I

$\Rightarrow ^2C_1$

Total no of ways of choosing a marble from bag-I

$\Rightarrow ^{10}C_1$

No of ways of choosing a blue marble from bag-II

$\Rightarrow ^{10}C_1$

Total no of ways of choosing a marble from bag-II

$\Rightarrow ^{20}C_1$

The probability that he will pull out a blue marble from each bag is

$\Rightarrow P=\text{Probability of pulling a blue marble from bag-I}\times \text{Probability of pulling a blue out bag-II}$

$\Rightarrow P=\dfrac{^2C_1}{^{10}C_1}\times \dfrac{^{10}C_1}{^{20}C_1}\\\\\Rightarrow P=\dfrac{2}{10}\times \dfrac{10}{20}=\dfrac{1}{10}$

What factor is used to convert feet per minute into miles per hour?

Liula [17]

For this case we have that in one hour there are 60 minutes. On the other hand, we have that 1 mile equals 5280 feet.

So, we have:

$\frac {ft} {min} = \frac {ft} {min} * 60 \frac {min} {h} * \frac {1} {5280} \frac {mile} {ft}\\\frac {ft} {min} = \frac {60} {5280} \frac {miles} {h}$

So, given an amount per foot per minute, we must multiply by $\frac {60} {5280}$ and get miles per hour

ANswer:

$\frac {ft} {min} = \frac {60} {5280} \frac {miles} {h}$
