For this case we have the following expression:
Let's evaluate the expression for some values of x.
We have then:
For x = 1:
For x = 2:
For x = 3:
For x = 4:
For x = 5:
Answer:
The value of the expression in ordered pairs is:
- (1,8)
- (2.6)
- (3,4)
- (4.2)
- (5.0)
A parent ticket cost $13.
A kids ticket costs $9.
53-40=13

Hope this helps!!! :)
Step-by-step explanation:
Given
Diameter (d) = 18 inch
π = 3.14
Area of circle(A)
= πd
= 3.14 * 18
= 56.52 inch ²
Answer:
a) 0.8132 or 81.32%
b) 0.1868 or 18.68%
c) 0.6116 or 61.16%
d) 0.7667 minutes
e) 0.8667 minutes
f) 0.1 minutes
Step-by-step explanation:
a)
If f(x) = 0.85-0.35x (0<x<2) is the <em>PDF</em> and X is the random variable that measures the time it takes for a trainee to complete the task, the probability a trainee will complete the task in less than 1.31 minutes is P(X<1.31)
b)
The probability that a trainee will complete the task in more than 1.31 minutes is
P(X>1.31) = 1 - P(X<1.31) = 1 - 0.8132 = 0.1868
c)
The probability it will take a trainee between 0.25 minutes and 1.31 minutes to complete the task is P(0.25<X<1.31)
d)
the expected time it will take a trainee to complete the task
is<em> E(X)
</em>
e)
f)
