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

|w| + 1.2 > 0.8 solution or no solution
Tasya [4]

You said              | w | + 1.2 > 0.8

Subtract  1.2  from each side:    | w | > -0.4

The absolute value of a number is always positive.
EVERY value of 'w' has an absolute value greater than -0.4 .
EVERY number is a solution to the equation.
There are an infinite number of them.

vredina [299]

Answer:

E = { x l x is a perfect square <36}

And we can rewrite it taking in count the list of all the perfect squares less than 36 and we have:

1= 1*1

4= 2*2

9 = 3*3

16 =4*4

25= 5*5

And we can rewrite the set on this way:

E= {1,4,9,16,25}

Step-by-step explanation:

For this problem we have the following set:

E = { x l x is a perfect square <36}

And we can rewrite it taking in count the list of all the perfect squares less than 36 and we have:

1= 1*1

4= 2*2

9 = 3*3

16 =4*4

25= 5*5

And we can rewrite the set on this way:

E= {1,4,9,16,25}
