Every time you roll you have a 1/6 chance so rolling 4 times you have a 6x4= 24 and 1x4=4 so you have a 4/24 chance of getting a 6

Answer:
x = 1/3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:
21x = 7
Divide 21 from both sides:
(21x)/21 = (7)/21
x = 7/21
x = 1/3
x = 1/3 is your answer.

The third one because it matches plus im copy
Given that the debt has been represented by the function:
f(x)=-6x^2+8x+50
To get the number of years, x that it would take for the company to be debt free we proceed as follows:
we solve the equation for f(x)=0
hence:
0=-6x^2+8x+50
solving for x using the quadratic formula we get:
x=[-b+/-sqrt(b^2-4ac)]/2a
x=[-8+/-sqrt(8^2-4*(-6)*50)]/(-6*2)
x=[-8+/-√1264]/(-12)
x=27.552
x~28
