Answer:2x^2-√(3)
Step-by-step explanation:
Sign change in the conjugate
Therefore we have 2x^2-√(3)
Answer:
Step-by-step explanation:
12
This is what we call a 45-45 traingle
This means that the lengths of the two non-hyptonouse lengths are the same
luckily we're given that it's 6√2
We can then use the pathagaryem theory to solve for the last side
we have
(6√2)²+(6√2)²=x²
Put this into your calculator and get
144= x²
x = 12
Answer:
Equal to
Step-by-step explanation:
Hello!
Let's simplify the left side:
Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.
Let's simplfy the right side:
Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.
So the inequality is 9 _ 9
Therefore the sign should be "=" as 9 is equal to 9.
The monthly failure rate is q = 5% = 0.05
The monthly pass rate is p = 1 - q = 0.95
We want to determine the probability of 12 passes in 12 consecutive months for a student.
P(12 of 12 successes) = ₁₂C₁₂ p¹² q⁰ = 0.95¹² = 0.5404.
Therefore if we have 100 students, the number that gets through 12 consecutive months is
100*005404 = 54 students.
Answer: 54 students are left after 12 months.
