Answer:
<h2>The Mean Absolute Vale (MAD) is 4.4</h2>
Step-by-step explanation:
The mean absolute deviation is defined as
Where is the mean and is the total number of data.
The means is defined as
And,
Replacing these values, in the MAD formula, we have
Therefore, the Mean Absolute Vale (MAD) is 4.4
Each student worked on 115 math problems.
Step-by-step explanation:
Given,
Problems solved in 4 hours = 8970
Number of students in competition = 78
As each student solved same number of problems, we will divide the total problems solved by number of students to find the amount of problems solved by one student.
Problems solved by one student =
Problems solved by one student = 115
Each student worked on 115 math problems.

Answer:
-9/8m+3/10
Step-by-step explanation:
7/8m + 9/10 -2m- 3/5
Combine like terms.
7/8m -2m +9/10-3/5
-9/8m+3/10
Quadratic equations are equations that has a leading degree of 2. The value of x from the given quadratic equation is 2 or -12
<h3>Quadaratic equation</h3>
Quadratic equations are equations that has a leading degree of 2
GIven the quadratic equation expressed as x^2 + 10x + 12 = 36
Rewrite
x^2 + 10x - 36 + 12 = 0
x^2 + 10x - 24 = 0
Factorize
x^2 + 12x -2x - 24 = 0
x(x+12) -2(x+12) = 0
x - 2 = 0 and x = -12
x =2 or -12
Hence the value of x from the given quadratic equation is 2 or -12
