Which scenarios have a negative correlation? check all that apply.
1) the number of calories consumed and the amount of weight lost by a person
2) the temperature outside and the number of pool guests
3) the number of children assigned to a class and the number of desks
4) the price of rice and the number of penguins at the south pole
5) the thickness of the ice on a lake and the likelihood of falling through the ice

Negative correlation is defined as an inverse relationship between two entities. If entity 1 increases, entity 2 decreases and if entity 2 increases, then entity 1 decreases.

According to this definition, option 1 and 5 are right answers.

1) the number of calories consumed and the amount of weight lost by a person - if more calories are consumed, person gains weight. If less calories are consumed, person loses weight.

5) the thickness of the ice on a lake and the likelihood of falling through the ice - if the ice sheet is thick, its less likely to fall and vice versa.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
