Answer:
Step-by-step explanation:
Let X = the monthly charges for cell phone plans
X is N(63, 17)
a) Normal curve with mean =63 and std dev =17
Find attachment
b) X<46
Since area = 0.1587, we get probability = 0.1587
P(X<46) = 0.1587
Y=2x+3
put x =0 onetime then y=3
now put y =0 2x+3
x= -3/2
Answer:
- ∞ < x < ∞
Step-by-step explanation:
The domain of a quadratic function is all real values of x , that is
- ∞ < x < ∞
