Answer:
a) 0.3571 = 35.71% probability that the stock price will be more than $25.
b) 0.1429 = 14.29% probability that the stock price will be less than or equal to $18.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:

The probability of finding a value between c and d is:

The probability of finding a value above x is:

Uniformly distributed between $16 and $30 per share.
This means that 
a) More than $25?

0.3571 = 35.71% probability that the stock price will be more than $25.
b) Less than or equal to $18?

0.1429 = 14.29% probability that the stock price will be less than or equal to $18.
Substitute
4x+2=x-4
Then solve
3x=-6
x=-2
Substitute answer into an equation to find y
y=-2-4
y=-6
So you solution is:
(-2,-6)
Answer:
Yes
Step-by-step explanation:
3(5+1)=3(5)+3
15+3=15+3
18=18
40.47×100=4047 so just multiply it and the the answer is 4047
