First, we need to work out the total number of students who were being surveyed.
We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population
That means total number of students being surveyed is 13+13=26 students
Then we work out the probability
P(One pet) = 8/26 = 4/13
P(Two pets) = 1/2
P(Three pets) = 3/26
P( Four pets) = 2/26 = 1/13
The probability distribution is shown in the table below. Let
be the number of pets and
is the probability of owning the number of pets

Step-by-step explanation:
Answer:
Option A) Circle.
Step-by-step explanation:
We are given the equation:
A general equation of the circle is of the form:
where (h,k) is the center of the circle and r is the radius of circle.
Comparing the two equations, we get,
Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.
Answer:
(a) --- The function
(b) --- The salary in 5 years
Step-by-step explanation:
Given
Solving (a): Model the function around (1,24100) and (3,36600)
First, we calculate the slope
The function is then calculated as:
Solving (b): Salary in 5 years
Here:
So:
