Answer:

1 /4 x 1/3 = 1/12

Step-by-step explanation:

The odds of pulling blue get lowered simply as there are larger random sample.

This is a way to ask about sample data even though this is probability question.

Why do we get a clearer picture with sample data the answer is we have a wider choice and lower odd as random occurs.There are more than 7 outcomes there are 12 outcomes for a b c d.

a 1 2 3

b 1 2 3

c 1 2 3

d 1 2 3

abcd = 12

ANSWER:

a) y = 15x + 75

b) 50 weeks

EXPLANATION:

P A R T A

2 weeks, 105 dollars --> (2, 105)

5 weeks, 150 dollars --> (5, 150)

if we use slope intercept form (y=mx+b), we must:

1) find the slope

y2 - y1 -->> 150 - 105 = 45

x2 - x1 -->> 5 - 2 = 3

45/3 = 15

2) find the y intercept

y = 15x + b -->> 150 = 15 (5) + b -->> 150 = 75 + b -->> 75 = b

--------------------------------------------------------------------------------------------

P A R T B

y = 15x + 75 (substitute the y with 825 because that is the goal)

825 = 15x + 75 (solve normally)

750 = 15x

50 = x

For the answer to the question above, I believe the answer is simply 8.

2 groups divided into four participants. So all in all people needed is 8.
I hope this helped you. Have a nice day!
