If 25% of the people <em>are</em> vaccinated, then 75% of the people are <em>not</em> vaccinated. Of those not vaccinated, each has a 50% chance of contracting the disease. The probability that someone is both not vaccinated and contracts the disease is (0.75)(0.5)=0.375.
The probability that someone is vaccinated and contracts the disease is (0.25)(0.1)=0.025 (it is multiplied by 0.1 because if the vaccine is 90% effective, then there is a 10% chance someone that is vaccinated can contract the disease.
Add these together for the total: 0.375+0.025=0.4
There is a 40% chance that someone chosen at random will contract the disease.
Answer:
3 = 14 and 4 = 8
Step-by-step explanation:
The reason as to why this is, is because of the line going down the middle. If you were to open one of the lengths as a door starting from the middle line it would fit perfectly with the top one.
Using the Pythagorean Theorem we can solve this.
OB = radius = 32
OC = 13
Lets solve for CB, which is half the length of AB.
CB = SQRT(32^2 - 13^2)
CB = SQRT(1024 - 169)
CB = SQRT(855)
CB = 29.24
AB = 29.24 x 2 = 58.48 = 58.5.
The answer is 58.5
Answer:
the answer would be y^6/x^2
Step-by-step explanation:
so (Y) to the sixth power over (X) to the second power
