Answer:
Population: The entire number of students present in town’s high school.
Sample: Identical number of students across various categories of freshers, senior students and juniors.
Step-by-step explanation:
Population is the large set of the people who are present during the experiment. Sample is a smaller subset from the population who become a part of the experiment. In this question, samples are the students who are either new joiners to the college, the senior students or the juniors. It will help Alan to come to a possible conclusion using the survey
Answer:
8xº = 90º
6xº = 67.5º
2xº = 22.5º
x = 11.25°
Step-by-step explanation:
The sum of angles in a triangle is 180°
8xº + 6xº + 2xº = 180º
16xº = 180º
x = 11.25º
8xº = 11.25(8) = 90º
6xº = 67.5º
2xº = 22.5º
Hope this helps :)
Answer:
x = 8
Step-by-step explanation:
20:30 = 2:3 = 1:1.5
18×1.5 = 27
27 = 2x +11
16 = 2x

Answer:
B ±sqrt((y-k)/a ) + h= x
Step-by-step explanation:
y=a(x-h)^2+k
Subtract k from each side
y-k = a(x-h)^2+k-k
y-k = a(x-h)^2
Divide by a
(y-k)/a = a(x-h)^2/a
(y-k)/a = (x-h)^2
Take the square root of each side
±sqrt((y-k)/a )= sqrt((x-h)^2)
±sqrt((y-k)/a )= (x-h)
Add h to each side
±sqrt((y-k)/a ) + h= (x-h+h)
±sqrt((y-k)/a ) + h= x
