Answer:
Equation 3: y = 12x + 17
Step-by-step explanation:
Only a linear equation (degree 1) will have a graph that is a straight line.
- Equation 1: degree 2
- Equation 2: degree 5
- Equation 3: degree 1
- Equation 4: degree 4
The degree of the equation is the highest power of any of the variables. If different variables are in the same term, it is the sum of the powers of those variables.
Sum of two monomials is not necessarily always a monomial.
For example:
Suppose we have two monomials as 2x and 5x.
Adding 2x+5x , we get 7x.
So if two monomials are both like terms then their sum will be a monomial.
Suppose we have two monomials as 3y and 4x
Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.
So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.
Product of monomials:
suppose we have 2x and 5y,
Product : 2x*5y = 10xy ( which is a monomial)
So yes product of two monomials is always a monomial.
Answer: Simple random sampling.
Step-by-step explanation:
A simple random sample is basically a subset (with size n) from the entire population, where the chance of getting selected for each element is equal.
Given :A research company believes teens today are getting less than the recommended hours of sleep. The company takes a list of 2000 teen volunteers and assigns each volunteer a number. A
A random number generator is used to select 350 individuals to take part in a sleep survey.
It is a simple random sampling because the researcher selected participants randomly such that the chance to get selected for each of them remains same.
