It would be best to list this values in the data set given, from least to greatest:
________________________________________________
{ 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times. The number, "4", occurs ONE (1) time. The number, "5", occurs TWO (2) times. The number, "6", occurs ONE (1) time. The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
The lowest values in the data set is: "3" .
The highest value in the data set is: "9" .
________________________________________________
To calculate the range: 9 <span>− 3 = 6 . The range is: "6".

Answer: The mode is: 3 . The range is: 6 .

Answer:
a) 0.1353
b) 0.3679
Step-by-step explanation:
Let's start by defining the random variable T.
T : ''The time (in hours) required to repair a machine''
T ~ exp (λ)
T ~ exp (1)
The probability density function for the exponential distribution is
(In the equation I replaced λ = L)

With L > 0 and x ≥ 0
In this exercise λ = 1 ⇒

For a)





For b)

The event (T ≥ 10 / T > 9) is equivalent to the event T ≥ 1 so they have the same probability of occur



Length A is (8,0) and the length of B is (0,6)
Answer:
48, 55, 56, 68, 74, 78, 83, 85, 99
Mean: 71.77777777777777777..........
Median: 74
Mode: mode is the number seen the most, but there is no repeating values
Range: 51
Step-by-step explanation:
<u>Mean:</u>
add all the values together, and divide by how many values you have, so 646/9= 71.777777777............
<u>Median:</u>
the number in the middle of the sequence
<u>Range:</u>
the difference between the largest and smallest numbers/values.
I hope this helps u pls give a brainliest and a thx ;)
Each book costs $15. 90 divided by 6 is 15 which is also 90 over 6.
