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

2) f(x) = 27x^6+ 1524x^3+125

Norma-Jean [14]

Answer:

Step-by-step explanation:

Let x^3 = y

f(x) = 27(x^3)^2 + 1524(x^3) + 125

f(x) = 27 y^2 + 1524y + 125

You can now put this into the quadratic formula. When you do, you get

(y + 0.0821)(y+56.3623) = 0

So now you substitute x^3 into this

(x^3 + 0.0821)(x^3 + 56.3623)

x^3 + 0.0821 = 0

x^3 = - 0.0821

cuberoot x^3 = cube root 0.0821

x = - 0.4346

x^3 = - 56.3623

x = - 3.8341
