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%

Chet started to slow his eating speed down later in the evening. He was
ozzi

Answer:

The unit rate is:

  • 1/8 turkey/per hour.

Step-by-step explanation:

As Chet was eating 1/4 of a turkey every 2 hours.

This tells us that every two hours, Chet will eat  175  1/4 of a turkey.

  • Unit rate basically means 'how much of something per 1 unit of something else'.

A unit rate is a rate with a denominator of  1  unit.

This means, in 1 hour, Chet will eat half of what he eats every 2 hours.

so Chet will eat \frac{\frac{1}{4}}{2}=\frac{1}{8} of a turkey in 1 hour.

i.e.

\frac{\frac{1}{4}}{2}=\frac{1}{8}

Therefore, the unit rate is:

  • 1/8 turkey/per hour.

A roof repairer works out that he will need to work with a colleage charges $20 per hour. In the end, they took 6 hours to fix t
ser-zykov [4K]

a) 20(x)=y

b) $120

Let x= number of hours

Let y= Cost of labor

20 will remain constant, what matters is how many hours are being worked. If it's $20 per hour then it's safe to assume 1 hour is 20 dollars worth of labor. Due to it being per hour you have to multiply the rate by however many hours worked to get your final cost.
