Answer:
(3.2, 0.6)
Step-by-step explanation:
means a translation of (x, y) → (x - 5.2, y + 1.4)
Suppose X has coordinates (a, b), after the translation is applied, X' has coordinates (a - 5.2, b + 1.4). X' is located at (-2, 2), therefore:
a - 5.2 = -2
a = -2 + 5.2
a = 3.2
b + 1.4 = 2
b = 2 - 1.4
b = 0.6
Answer:
43.24% probability that the student will be a boy
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
Student being a boy.
8 boys from Wilmette
5 boys from Glencoe
3 boys from Winnetka
So
Total outcomes:
All students
Probability:
