Answer:
The sequence is a function as for any value of n we can not get more than one different 
value.
Step-by-step explanation:
Tilly starts by running 1 mile in the first week and tripling the number of miles each week.
Now, the number of miles Tilly will run can be modeled by the sequence 
, where n is the number of weeks since she began her program.
Therefore, in the second week she runs 3 miles, in the third week she runs 9 miles and so on.
Therefore, the sequence is a function as for any value of n we can not get more than one different value. (Answer)
Answer:
P = 1 / 40320 or P = 2.48*10⁻⁵
Step-by-step explanation:
The total number of outcomes To is:
To = 8! To = 8*7*6*5*4*3*2
To = 40320
Of all these outcomes there is only one proper outcome, therefore the probability of having all men and women in alphabetical order is:
P = 1 / 40320 or P = 2.48*10⁻⁵
Answer:
0.00397
Step-by-step explanation:
I am taking a guess. Like I saw this example (5/9)(4/8)(3/7)(2/6)=120/3024=0.0397
Or (5C4)/(9C4)=0.0397 - from chisnau
Follow those steps, but add your numbers . I added one zero bassed on the problem: There are 9 students in a class: 5 boys and 4 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?
Hope I helped in some way!
The answer is hundred and twenty-two decimal eight
