Answer:
The odds are 100 out of 200% for both to have heads.
The actual probility is 50%
Step-by-step explanation:
X = large bag of popcorn
y = small bag of popcorn
x + y = 200...x = 200 - y
4x + 6y = 900
4(200 - y) + 6y = 900
800 - 4y + 6y = 900
-4y + 6y = 900 - 800
2y = 100
y = 50 <=== large bags sold
x + y = 200
x + 50 = 200
x = 200 - 50
x = 150 <== small bags
The required expression is 100 - 0.2w
Step-by-step explanation:
Given,
Amount of radioactive substance = 100 mg
The substance decreases by 20% each week.
To find the remaining amount of the in w weeks.
Now,
Each week 20% = 0.2 of the substance will be decreased.
So, in w weeks 0.2×w of the the substance will be decreased.
Hence,
The remaining substance = 100 - 0.2w
