Answer:
Cluster sample
Step-by-step explanation:
This is an example of a cluster sample. In a cluster sample, the examiner divides the population into groups (each one of these groups is called a cluster) and once the examiner has these clusters, takes one of them and recollects the data from ALL the members of that cluster. In this case, the teacher divided the class in 3 different groups and then selects one of these groups and asks the average amount of time per week he/she spent studying.
Rotation: a b
Translation:e j
Reflection over a horizontal line: g f
Reflection over a vertical line: c e
Rotation then reflection: a h
Rotation then translation: a d
I’m sorry if this isn’t right
2x - 3y = 9
- 3y = -2x + 9
y = (-2x + 9)/-3
slope = -2
Since the slope is negative the line passes through quadrants 2 and 4
Therefore the answer is b.
Answer:
- x -19.35 ≥ 97.22
- at least $116.57
Step-by-step explanation:
"At least" means "greater than or equal to."
x - 19.35 ≥ 97.22
x ≥ 116.57 . . . . . . . . . add 19.35
Bella originally had at least $116.57 in her account.
