Step-by-step explanation:
9)
a) Range is the highest value - lowest value => 42-17=25
b) Mean is the sum of all terms divided by the total number of terms
=> 365/12 = 30.41
c) for median list them in ascending or descending order and calculate the average of the 6th and 7th term, the median would come out to be 33.

a) since all are vowels, the chance or probability is 1.
b) since there is just 1 "u" and other are different, the probability is 1/5
c) since its ''a'' or ''i'', it would be the sum of the individual probabilities, that is 1/5 + 1/5 = 2/5
d) since all are vowels and no consonants, hence 0.
Answer:
Mean 30.41
Medain = 33
Mode = 35
Range = 25
Probability of any vowel = 1
Probability of U = 1/5
Probability of A & I = 2/5
consonant probability = 0
Step-by-step explanation:
31 , 37 , 35 , 38 , 42 , 23 , 17 , 18 , 35 , 25 , 35 , 29
Sum of all = 365
Arrange in ascending order
17 , 18 , 23 , 25 , 29 , 31 , 35 , 35 , 35 , 37 , 38 , 42
Mean = 365/12 = 30.41
Mode = 35 ( repeating 3 Times)
Median = Mean of 6th & 7th digit in ascending order = (31+35)/2 = 33
Range = 42 -17 = 25
Next question
Probability of vowel = 5/5 = 1
Probability of U = 1/5
Probability of A & I = 2/5
No consonant there so probability = 0/5 = 0
