Answer:
A. 2 distinct roots.
Step-by-step explanation:
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
Simplify the denominator so it is the same
divide the 4 by 2
4 divided by 2=2
now the denominator the same.
16 1/2
2 3/2
multiply 3x1
so far, it is 3/2
it is an improper fraction
divide.
2 divides by 3 = 0.1 i know
1/2
Hope this helped :D! can you mark me brainliest...
Answer:
a) 256
b) 1/256
Step-by-step explanation:
_ _ _ _ _ _ _ _
every position has two possibilities (head or tail)
So,
2×2×2×2×2×2×2×2 = 2⁸ = 256
b) all tails is one of the 256 possible outcomes, so the probability is 1/256
