Since 10 out of 14 marbles are green, the probability of selecting a green marble is 10/14=0.714.

Similarly, the probability of selecting a red marble would be 4/14.

Answer: 0.714

Well a clock has twelve hours that make up a full circle, or 360 degrees, so you divide 12 by 360 then multiply by the degree, which in this case is 81.81 and that's the number of hours. (You figure out the minutes by looking at the decimal)

Which is the best estimate for the percent equivalent to 3/8​
Doss [256]

Answer:

D. 38%

Step-by-step explanation:

3/8 as a percentage is 37.5% and that is rounded to 38%! :) 37% is close but it is not rounded making it not the best estimate, therefore it is not correct.

.109 is what in fraction form?
dezoksy [38]

Answer: 109/1000

.109 can not be reduced, so we must put it in a fraction with 1,000.

So, the fraction would be 109/1000, because we need a denominator as 1,000.

The answer = 109/1000

James works for a delivery company. He gets paid a flat rate of $5 each day he works, plus an additional amount of money for eve
otez555 [7]

Answer:

(a) The rate of change for the money earned, measured as dollars per delivery, between 0 and 2 deliveries is $2.

(b) The rate of change is the same between the two time intervals.

Step-by-step explanation:

The rate of change for a variables based on another variable is known as the slope.

The formula to compute the slope is:

\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

(a)

Compute the rate of change for the money earned, measured as dollars per delivery, between 0 and 2 deliveries as follows:

For, <em>x</em>₁ = 0 and <em>x</em>₂ = 2 deliveries the money earned are <em>y</em>₁ = $5 and <em>y</em>₂ = $9.

The rate of change for the money earned is:

\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

        =\frac{9-5}{2-0}\\\\=\frac{4}{2}\\\\=2

Thus, the rate of change for the money earned, measured as dollars per delivery, between 0 and 2 deliveries is $2.

(b)

Compute the rate of change for the money earned, measured as dollars per delivery, between 2 and 4 deliveries as follows:

For, <em>x</em>₁ = 2 and <em>x</em>₂ = 4 deliveries the money earned are <em>y</em>₁ = $9 and <em>y</em>₂ = $13.

The rate of change for the money earned is:

\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

        =\frac{13-9}{4-2}\\\\=\frac{4}{2}\\\\=2

The rate of change for the money earned, measured as dollars per delivery, between 2 and 4 deliveries is $2.

Compute the rate of change for the money earned, measured as dollars per delivery, between 6 and 8 deliveries as follows:

For, <em>x</em>₁ = 6 and <em>x</em>₂ = 8 deliveries the money earned are <em>y</em>₁ = $17 and <em>y</em>₂ = $21.

The rate of change for the money earned is:

\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

        =\frac{17-21}{8-6}\\\\=\frac{4}{2}\\\\=2

The rate of change for the money earned, measured as dollars per delivery, between 6 and 8 deliveries is $2.

Thus, the rate of change is the same between the two time intervals.
