X^2-4x+5=8 so let's complete the square, subtract 5 from both sides
x^2-4x=3 halve the linear coefficient, square it, and add it to both sides...(-4/2)^2=4
x^2-4x+4=7 now the left side is a perfect square of the form
(x-2)^2=7 take the square root of both sides
x-2=±√7 add 2 to both sides
x=2±√7
So A. is your answer.
Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26
