It will take them 80 days to sprint 20 miles.
The method that can be used in solving this type of question involves the use of equating fractions together with their arithmetic operation.
<h3>What is a fraction?</h3>
A fraction usually consists of two terms with a term located in the upper part called the numerator and another term located in the lower part called the denominator.
From the parameters given:
- The track team has a plan to sprint 20 miles this school year.
- If the runners participating in the event sprint 1/4 miles in each day.
Then, the estimate of the number of days it will take them to sprint 20 miles can be computed as:
= 80 days

<span>y - 6 = 5(x - 2)
As you know y - y1 = m(x - x1) where m = slope
in this case </span>y- 6 = 5(x - 2), m = 5
Answer: Slope m = 5
2/5 + 6/7 + 2/3....lowest common denominator is 105
42/105 + 90/105 + 70/105 = 202/105 =1 97/105 or 1.92 miles
The probability of drawing a red marble and then a green marble is:
P = 1/6.
<h3>How to find the probability?</h3>
In the jar we have a total of 16 marbles, such that:
- 10 are green.
- 2 are blue
- 4 are red.
First, the probability of getting a red marble is give by the quotient between the number of red marbles and the total number of marbles:
p = 4/16 = 1/4
Now we need to draw a green one, the probability is computed in the same way, but this time there are 15 marbles, because we already took one.
q = 10/15
The joint probability (first drawing red, then green) is given by the product between the individual probabilities:
P = p*q = (1/4)*(10/15) = 10/60 = 1/6
