Answer:
Option A.
Step-by-step explanation:
The general form of a quadratic function is
It means, power of y should be 1 and highest power of x should be 2.
In option A,
It is a quadratic function.
In option B,
Here, power of y is 2. So, it is not be a quadratic function.
In option C,
Here, highest power of x is 3. So, it is not be a quadratic function.
In option D,
Here, highest power of x is 1. So, it is not be a quadratic function.
Therefore, the correct option is A.
Answer: The required probability is 2.24%.
Step-by-step explanation:
Since we have given that
Percentage of people are senior citizens ( 65 years old or older ) = 14%
Percentage of people are under 65 years old = 100-14 = 86%
Probability that senior citizens get the flu each year = 16%
Probability that under 65 years old get the flu each year = 30%
So, Probability that a person selected at random from the general population is senior citizen who get the flu this season is given by
Hence, the required probability is 2.24%.
Answer:
Step-by-step explanation: You have to do the distributive property to get the answer.
Answer:f(x)= 3*1/k
8=3*1/k
K=3/8
When x=2
f(x)=2*3/8
f(x)=3/4
