F(x) = 2x2 – 4x – 30 = 2x2 – 4x – 33 = 2(x2 – 2x)3 + 1 = 2(x2 – 2x + 1)4 = 2(x – 1)22 = (x – 1)2± = x – 11 ± = x mica is solving for the zeros of a quadratic function by completing the square. her work is shown. what error did mica make?

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

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 : )
