There are 196 countries in the world. How many students must be enrolled in a university to guarantee that there are at least 20
cestrela7 [59]

Answer:

At least 39200 students.

Step-by-step explanation:

Given that there are 196 countries in the world, and each country would have at least 200 students in a university.

For each country to have at least 200 students in the university, then;

Number of students enrolled in the university = number of required students x number of countries

                                      = 200 x 196

                                      = 39200

At least, 39200 students must be enrolled in the university. Provided that the admission procedures are conditioned for the purpose.

Anastaziya [24]

Answer:

y = x - 2 could not be the function equation.

Step-by-step explanation:

The function with an input of 3 has an output of 5.

So, y = 2x - 1 can be the function as y(3) = 2 × 3 - 1 = 6 - 1 = 5.

Now, y = x + 2 can also be the function as y(3) = 3 + 2 = 5

Again, y = 3x - 4 can also be the function as y(3) = 3 × 3 - 4 = 9 - 4 = 5

But y = x - 2 can not be the function as y(3) = 3 - 2 = 1 ≠ 5

Therefore, y = x - 2 could not be the function equation. (Answer)
