Answer:15504
Step-by-step explanation:
We know to select any r no of non-consecutive element for n consecutive elements is given by

Here n=24 and r=5
Therefore no of ways



I would think that all but one point would be on the line. One way to approach this problem is to find the equation of the line based upon any two points chosen at random, and then determine whether or not the other points satisfy this equation. Next time, would you please enclose the coordinates of each point inside parentheses: (2.5,14), (2.25,12), and so on, to avoid confusion.
14-12
slope of line thru 1st 2 points is m = ---------------- = 2/0.25 = 8
2.50-2.25
What is the eqn of the line: y = mx + b becomes
14 = (8)(2.5) + b; find b:
14-20 = b = -6. Then, y = 8x - 6.
Now determine whether (12,1.25) lies on this line.
Is 1.25 = 8(12) - 6? Is 1.25 = 90? No. So, unless I've made arithmetic mistakes, (1.25, 5) does not lie on the line thru (2.5,14) and (2.25,12).
Why not work this problem out yourself using my approach as a guide?
Answer:
B. Bradley
Step-by-step explanation:
We know that Ellen can type 205 words in 5 minutes. To start comparing to the other students, we need to find out how many words she can type per minute. We can divide 205 by 5 to get our answer.


<u>Ellen can type 41 words per minute</u>. To find our answer we must find how many words per minute the other students can type. Lets start with the first and go down from there:
Alissa:


It can't be Alissa.
Bradley:


Your answer is B. Bradley
