Step-by-step explanation:
33/4=8.25
-21/2= -10.5
8.25÷-10.5=0.785
The sample of the population is 100 students since they acquired answers from students from middle school and high school, having 50 students each school. 50 + 50 = 100 students as the sample. The total population for either or both of the schools is/are undetermined.
Answer:
Step-by-step explanation:
y=a(x-0)(x-2)
=a(x^2-2x)
=a(x^2-2x+1-1)
or y=a(x-1)^2-a
(1,5) lies on it.
5=a(1-1)^2-a
5=0-a
or a=-5
so y=-5(x-1)^2+5
I believe it's a solution
