Answer:
∠ 1 = 120°
Step-by-step explanation:
Note that ∠ Q and ∠ R are congruent, that is both 30°, thus
∠ 1 = 180° - (30 + 30)° = 180° - 60° = 120°
A is a function
To represent a function each value from the input (x ) can only map to exactly one value in the output (y)
In B
x = 3 → y = 10/ 30 ← 2 values of y
In C
x = - 5 → y = 2/ 3 ← 2 values of y
x = - 10 → y = 4/ 5 ← 2 values of y
In D
x = 20 → y = 25/ 35 ← 2 values of y
A is the only table where each value of x maps to exactly one value in y

Answer:
a) 0.75
b)5.05
c)0.02
Step-by-step explanation:
a)
P(Y>5)=?
This part is solved in the given picture.
b)
The mean of a uniform distribution is (a+b)/2.
Where a=4.95 , b=5.15.
E(Y)=(4.95+5.15)/2
E(Y)=10.1/2
E(Y)=5.05.
c)
The variance of a uniform distribution is (b-a)²/2.
V(Y)=(5.15-4.95)²/2
V(Y)=0.2²/2
V(Y)=0.04/2
V(Y)=0.02.
