You need to know the distribution's mean and standard deviation.

Transforming to the standard normal distribution, and letting

denote the standard deviation,

The z-score corresponding to this probability is approximately

, so you have
In the problem above, let x be the cost of ticket for adults. Based on the description stated by the clerk, each child's ticket costs x - 11.
The total cost of the ticket is $174.45 and may be used to get the value of x. The equation is,
2x + 3(x - 11) = 174.45
Solving x in the equation gives x = 41.49 and x -11 = 30.49. Thus, each adult's ticket cost $41.49 and child's ticket costs $30.49.
Answer:
y = 6x + 0
Step-by-step explanation:
Lets find the rate of change, or slope:
ROC = 
ROC = 
ROC = 
ROC = 6
So, now we can input 6 in y = 6x + b
Now lets pick an x and y value (Im picking 5 and 30, but you can another one)
30 = 6(5) + b
30 = 30 + b
b = 0
The equation is y = 6x + 0
