Answer:
- North Middle School = 10 students
- Central Middle School = 6 students
- South Middle School = 4 students
Step-by-step explanation:
First calculate the total number of students in all the schools:
= 618 + 378 + 204
= 1,200 students
Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.
North Middle school:
= 618/1,200 * 20
= 10 students
Central Middle School:
= 378 / 1,200 * 20
= 6 students
South Middle School:
= 204/1,200 * 20
= 4 students
Answer:
A) Real Roots
B) Imaginary Roots
C) Equal Roots
D) Unequal Roots
E) Rational Roots
F) Irrational Roots
Step-by-step explanation:
The equation with one variable , in which the highest power of variable is two , is know as QUADRATIC EQUATION
ex - 3x² + 4x + 7 = 0
Every quadratic equation gives to values of unknown variables and these values is called roots of equation .
The quadratic equation have three roots :
A) Real Roots
B) Imaginary Roots
C) Equal Roots
D) Unequal Roots
E) Rational Roots
F) Irrational Roots
The nature of Roots depends entirely on the value of it Discriminant
If D = 0 , Roots are real and equal
If D , roots are real and unequal
If D ,roots are imaginary
where D = b² - 4ac for any quadratic equation ax² + bx + c = 0
