The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.
Subtract 9.4 from both sides.
2x = 10.6
Divide by 2.
x = 5.3
The answer is the value of x that makes this equation true is 5.3
Hope this helps

Answer:
18 minutes
Step-by-step explanation:
Given that:
The arrival time = 3 customers / hour
The avg. service rate (s) = 12 minutes per customer
To hour, we have:
s = 5 customers/ hour
Thus, the required average time for a customer needs to wait in line is:
To minutes;
= 18 minutes
Answer:
Step-by-step explanation:
a.
let A= number 5
B=number >3
P(A)=1/6 {5}
P(B)=3/6 {4,5,6}
p(A∩B)=1/6 {5}
P(AUB)=P(A)+P(B)-P(A∩B)=1/6+3/6-1/6=3/6=1/2
b.
let event C=number<5
D=even number
C=[1,2,3,4}
D={2,4,6}
C∩D={2,4}
P(C)=4/6
P(D)=3/6
P(C∩D)=2/6
P(C∪D)=P(C)+P(D)-P(C∩D)=4/6+3/6-2/6=5/6
c.
let event E=number 2
F= an odd number.
E={2}
F={1,3,5}
E∩F={}
P(E)=1/6
P(F)=3/6
P(E∩F)=0
P(E∪F)=P(E)+P(F)-P(E∩F)=1/6+3/6-0=4/6=2/3
An independent variable is a variable that can either be changed or controlled. We represent the independent variable as (X).
Let's look at an example.
<em>The number or hours Mike works at Sea World in June and the amount of money he will earn on his July paycheck.</em>
The independent variable because the amount of money he makes depends on how much money he earns.
