Answer: you could do store A is $8 per hour, and thirteen $13 per day, store B can be $3 per hour, $18 per day
I'm not too confedent but I'm still happy to help!
For this case, we have by definition that, the median of a set of numbers is the average number in the set, after the numbers have been ordered from lowest to highest. If there is an even number in the set, the median is the average of the two middle numbers.
So, the given set is:
{4,5,5,6,10,11,12,13}
Since there are 8 numbers, the set is even. Then we find the average of the two numbers in the middle:

The median is 8
ANswer:
8
Answer:
y= 3/2x + 24
Step-by-step explanation:
the slope of the line can be found with this formula: (y2-y1)/(x2-x1) where x and y are the coordinates of two points.
m = (9-6)/(-10+12) = 3/2
for find the equation or the line we can use this formula:
y-y1 = m(x-x1)
y-9 = 3/2(x+10)
y = 3/2x +15+9
y = 3/2x + 24
Answer:
(a) Sample Space

(b) PMF

(c) CDF

Step-by-step explanation:
Solving (a): The sample space
From the question, we understand that at most 3 cars will be repaired.
This implies that, the number of cars will be 0, 1, 2 or 3
So, the sample space is:

Solving (b): The PMF
From the question, we have:



can be represented as:
![P(1) + P(2) = 0.5[P(0) + P(3)]](https://tex.z-dn.net/?f=P%281%29%20%2B%20P%282%29%20%3D%200.5%5BP%280%29%20%2B%20P%283%29%5D)
Substitute
and 
![P(1) + P(1) = 0.5[P(0) + P(0)]](https://tex.z-dn.net/?f=P%281%29%20%2B%20P%281%29%20%3D%200.5%5BP%280%29%20%2B%20P%280%29%5D)
![2P(1) = 0.5[2P(0)]](https://tex.z-dn.net/?f=2P%281%29%20%3D%200.5%5B2P%280%29%5D)


Also note that:

Substitute
and 


Substitute 



Solve for P(1)

To calculate others, we have:






Hence, the PMF is:

<em>See attachment (1) for histogram</em>
Solving (c): The CDF ; F(x)
This is calculated as:

For x = 0;
We have:


For x = 1



For x = 2



For x = 3



Hence, the CDF is:

Answer:
64 degrees
Step-by-step explanation
multiply 4 by 16 because for every hour it was cooled another 4 degrees so 4 times 16 equals 64
