Answer:
B) Convergent infinite geometric series sum to a single value
Step-by-step explanation:
An infinite geometric series of the form 
converges if 
, so the summation of the series will result in a single value if that is true.
Answer:
See below.
Step-by-step explanation:
ax^2 + bx + c = 0
a(x^2 + b/a x) + c = 0
Completing the square:
a [ (x + b/2a)^2 - b^2/4a^2] + c = 0
a[ (x + b/2a )]^2 - b^2 / 4a + c = 0
a[ (x + b/2a )]^2 = b^2 / 4a - c
Dividing both sides by a:
(x + b/2a )^2 = b^2/4a^2 - c/a
Taking square roots of both sides:
x + b/2a = +/- √ (b^2/ 4a^2 - c/a)
x + b/2a = +/- √ [ ( b^2 - 4ac) / 4a^2 )]
x + b/2a = +/- √ ( b^2 - 4ac) / 2a
Subtracting b/2a from both sides and converting the right side to one fraction:
x = [- b +/- √ ( b^2 - 4ac] / 2a.

One side is colored for you, you can do same for the other side
Answer:
300 students
Step-by-step explanation:
There are two ways to solve this question.
60 is 20% of the total students
20÷100= 0.2
60÷0.2=300
Therefore there are 300 students
60 is 20% of the total students
60/20 = x/100
x= 60*100÷20
x= 6000÷20
x= 300
Therefore there are 300 students.
Hi!
If you have a 1/4 change of winning, the chance of not winning is
4/4 - 1/4 = 3/4
The answer is 3/4
Hope this helps! :)
