Answer:
0 tests
Yes, this procedure is better on the average than testing everyone, it makes it less cumbersome.
Step-by-step explanation:
Given the information:
Let P be the probability that a randomly selected individual has the disease = 0.1. N individuals are randomly selected, thereafter, blood samples of each person would be tested after combining all specimens. Should in case one person has the disease then it yields a positive result and test should be set for each person.
Let Y be number tests
For n = 3 there are two possibilities. If no one has the disease then the value is 1 otherwise the value is 4, here P = 0.1
Therefore, for Y = 1
P(Y-1) = P(no one has disease)
= 0.9³
= 0.729
If Y = 4
P(Y-4) = 1-P(y = 1)
= 1 - 0.729 = 0.271
The expected number of tests using this formular gives
E(Y) = 1×0.729 + 4×0.271
E(Y) = 0
Answer: 37.5
Step-by-step explanation: just multiply! hope this helps!
Answer:
The correct answer is 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.
Step-by-step explanation:
If x = 0.5, then 5x^3 = 5.5^3.
5.5^3 is the same as <em>multiplying </em>5.5 by <em>itself </em> 3 times.
5.5 x 5.5 x 5.5 = 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.
Hope this helps! :D
Neither median means in the middle unless u start from highest to lowest and cancel out letters
