42 students ran in a race. a third of them dropped out in the first half of the race. only a fourth of the remaining runners actually did complete the race. how many students finished the race? (check work required)

The number of the students that remained in the race after the first half is calculated by multiplying the number of students by 2/3 because 1/3 of them dropped out.

                         N (first half) = 42 x 2/3

                         N (first half) = 28

Then, the number of students who finished the race is one-fourth of the calculated number above. Thus, the final answer to this item would be 14.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
