Answer:

0.62

Step-by-step explanation:

In the picture attached, the table is shown.

We want to find the probability that a student uses the Internet, given that he or she is in eighth  grade. Mathematically:

P(Internet | eighth  grade) = P(Internet ∩ eighth  grade)/P(eighth  grade)

P(Internet | eighth  grade) = (8/28)/(13/28) = 8/13 = 0.62

Use algebraic means to show that x^2 + y^2 = 8 is not a function. Explain your process.
11Alexandr11 [23.1K]

Answer:

For a single value of x function has more than one corresponding value of y which satisfies the equation.

Step-by-step explanation:

Function: A relationship between a set of inputs and a set of possible outputs, where exactly one output is associated with each input.

It means for an equation to represent a function any single value of  x there should be only one corresponding value of  y which satisfies the equation.

Now consider the given equation.

x^2 + y^2 = 8

If we put x=0 then we get two value of y i.e \sqrt8 and -\sqrt8 which satisfy the equation  and therefore the equation is not a function.
