Answer:

Domain: (-∞, ∞), or x∈R, or -∞<x<∞

Range: (-∞, ∞), or y∈R, or -∞<y<∞

Step-by-step explanation:

Domain and range are all real numbers. Domain is all values of x, range is all values of y.

Domain: (-∞, ∞), or x∈R, or -∞<x<∞

Range: (-∞, ∞), or y∈R, or -∞<y<∞

Visitors to a carnival are invited to guess the number of beans in a jar. The person who guesses the correct number wins $300 if

The relationship between the two variables is inverse proportionality, that is, the greater the number of people, the less the amount of money earned.

Since visitors to a carnival are invited to guess the number of beans in a jar, and the person who guesses the correct number wins $ 300, but if multiple people guess correctly, the prize will be divided evenly among them, to determine what is the relationship between the number of people who guess correctly and the amount of money each person will recieve the following logical reasoning must be performed:

Since the prize is a fixed number, 300, it is a value that will not change. In turn, the more people who have guessed right, the lower the amount of money that each of them will win (because the number 300 will be divided by a greater number).

Therefore, the relationship between the two variables is inverse proportionality, that is, the greater the number of people, the less the amount of money earned.

Question 2 Answer Solve

Lelu [443]

Answer:

Option B is correct.

Step-by-step explanation:

To subtract fractions, we must check if the denominators of both fractions are the same.

2/5 - 1/7
=> 2 x 7/5 x 7 - 1 x 5/7 x 5
=> 14/35 - 5/35

Now, let's subtract for the result.

=> 9/35

Hence, Option B is correct.

Answer:

The maximum possible number of mosquitoes is 25 millions

Step-by-step explanation:

Let

m(x) -----> the number of mosquitoes in Minneapolis, Minnesota (in millions of mosquitoes)

x ----> the rainfall in centimeters

we have

$m(x)=-(x-5)^{2} +25$

This is a quadratic equation (vertical parabola) open downward

The vertex is the maximum

we know that

The maximum possible number of mosquitoes is equal to the y-coordinate of the vertex

Find out the coordinate of the vertex

The general equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2} +k$

where

a is a coefficient

(h,k) is the vertex

In this problem

a=-1 (open downward)

(h,k)=(5,25)

The y-coordinate is 25

therefore

The maximum possible number of mosquitoes is 25 millions

Anna007 [38]

Answer:

It is reasonable.

Step-by-step explanation:

If you add 468 (amount of animals already there) and add how ever many more coming (192) then you'll get 680. If you add 100 more that will only be 780 animals.
