worty [1.4K]

Answer:

3.7%

Step-by-step explanation:

We know that from this situation, the probability of drawing a single green marble is 1/3. However, to find the probability of drawing 3 green marbles, we will need to do:

$P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}$

We get a probability of:

$P= \frac{1}{27}$

This converts to a percentage of:

$\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%$

We get a percentage of 3.7%

An ice cream factory makes 29 quarts of ice cream in 5 hours. How many quarts could be made in 48 hours ? What was that rate per

Vadim26 [7]

We can easily get the quarts per hour rate by dividing the number of quarts by the number of hours:

$\text{29 quarts in 5 hours} \implies \dfrac{29}{5} = 5.8 \text{ quarts in 1 hour}$

Now that we have the quarts per hour rate, we can easily address the question: the factory could make

$5.8\cdot 48 = 278.4$

quarts in 48 hours, with a daily rate of

$5.8\cdot 24 = 139.2$

quarts per day
