Since the exterior angle of a triangle is equal to the sum of the interior opposite angles, angle 5 = 90 + angle 1.
Given that angle 5 = 147, 147 = 90 + x.
x = 57 degrees.
So, angle 1 is 57 degrees.
Which of the following relations represents a function? A. {(1, 1), (1, 2), (1, 3)} B. {(1, 1), (2, 1), (3, 1)} C. {(1, 1), (2,

Answer:
D. Both B and C.
Step-by-step explanation:
For an ordered pair relation to represent a function, then none of the first coordinate must repeat.
In other words, no two or more ordered pairs should have the same first coordinate.
For options A, the first coordinate repeated.
For options B and C, none of the first coordinates repeat.
Both represent a function.
The correct choice is D
Answer:
y=17,x=15
Step-by-step explanation:
180-112=68
68/4=y=17
180-68=112
112-7=105
105/7=x=15
Answer: z(99) = (99-98.2)/0.62 = 1.2903
P(x < 99) = P(z < 1.2903) = 0.9015 = 90.15%ile
