Answer: 11.9%
Step-by-step explanation:
Given : On a stretch of Interstate-89, car speed is a normally distributed variable with 
mph and 
mph.
Let x be a random variable that represents the car speed.
Since , 
z-score corresponds x = 73 , 
Required probability :
[using z-value table.]
Hence, the approximate percentage of cars are traveling faster than you = 11.9%
Answer:
Let Craigs age = x
Therefore Dianes age = 25 + x ( since she's 25 years older)
Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)
25 + 2x = 105
2x = 80
x = 40
Craigs age is 40 years old.
Dianes age is 65 years old.

Answer:
A. x^2 + 3x + 2
D. 3x^4 + 4x^3 - 3x^2 - 1
E. 3t^3 + 3t^2 + 2t
Step-by-step explanation:
Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
