The ratio of females to males would be 12:16, but reduced it would be 3:4
Answer:
(30-5n)
Step-by-step explanation:
The given sequence is :
25,20,15,10,5
Here,
First term, a = 25
Common difference = 20-25 = -5
We need to find the nth term of the given sequence. The formula for the nth term is given by :
So, the nth term of the above sequence is (30-5n).
Answer:
The probability that a randomly chosen person has measles antibodies in his/her blood if the new test is positive = 0.9796
Step-by-step explanation:
The event that someone tests positive = P(T)
The event that someone has antibodies = P(A)
The event that someone does not have antibodies = P(A')
The new test was positive when administered to 96% of those who have the antibodies.
This probability = P(T n A) = 0.96
The new test gave positive results in 2% of those who do not have them.
This probability = P(T n A') = 0.02
The probability that a randomly chosen person has measles antibodies in his/her blood if the new test is positive = P(A|T)
This conditional probability is given as
P(A|T) = P(T n A) ÷ P(T)
P(T) is given as
P(T) = P(T n A) + P(T n A') = 0.96 + 0.02 = 0.98
P(A|T) = P(T n A) ÷ P(T) = 0.96 ÷ 0.98 = 0.9796
Hope this Helps!!!
Answer: See explanation
Step-by-step explanation:
You have to remeber that x to the power of r/q is the same thing as the qth root of x to the power of r.
For the second one, you would have the cubic root of 2 to the power of 2, or 4. So, your answer would be ![\sqrt[3]{4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4%7D)
.
For the third one, you would have the square root of 3 to the power of 3, or 27. So, your answer would be ![\sqrt[2]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B27%7D)
.
For the fourth one, you would have the cubic root of 3 to the power of 1, or 3. So, your answer would be ![\sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%7D)
.
