Answer:
Y = 45*p(y) / (1 - p(y)) if I knew what p(y) is, we can find how many yellow marbles there are. p(y) = probability of choosing yellow.
Step-by-step explanation:
Total marbles = 35 + 10 + yellow
If probability of choosing yellow =p(y) = yellow/Total
p(y) = Y/(35 + 10 + Y)
Solve for Y,
p(y)*(35 + 10 + Y) = Y
45*p(y) + p(y)*Y = Y
45*p(y) = Y - p(y)*Y
Y = 45*p(y) / (1 - p(y))
Answer:
Its c
Step-by-step explanation:
The tenths place would be the digit right after the decimal point, and we want to round 479.16 to the nearest tenths.
The number in the tenths place is 1. Now we have to decide if we're going to round up or down
- If the next digit is greater than or equal to 5, we round up (add 1 to the digit); if it isn't, then we round down (the digit stays the same).
The digit after the tenths place is "6", which is greater than 5. Thus, the "1" is rounded up to a "2"
Answer: 479.16 to the nearest tenths is 479.2.
Let me know if you need any clarifications, thanks!
