<span>Equation:
silver + silver = silver
0.45x + 0.60(40-x) = 0.48*40
----------------
45x + 60*40 - 60x = 48*40
--------
-15x = -12*40
x = (4/5)40
x = 32 lbs (amt of 45% slloy needed)
40-x = 8 lbs (amt of 60% alloy needed)</span>
Answer:
2/15
Step-by-step explanation:
The answer choices to this question do not make sense since probability is a measure that is always <= 1.0
Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles
Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45
Probability of drawing a green tile = 6/45 = 2/15

<u>Comparing sales by the ratio of sold to all or</u>
- Sales = sold / (remaining + sold)
<u>Applying to our table:</u>
- New Labels: p/(p+q)
- Old labels: r/(r+s)
Correct answer option is the last one
I hope this helps you
Area=pi.r^2
r^2=Area/pi
r= square root of Area/pi
