What the answers choices?
Answer:
0.8
Step-by-step explanation:
A: P(1) = .6, P(2) = .5, P(1 and 2) = .3
P(1 or 2) = P(1) + P(2) - P(1 and 2) .6 + .5 - .3 = 0.8
Answer:
x = -1 and x = 4
Step-by-step explanation:
Step 1: Get everything to one side of the equation so it's set equal to zero..
-x² + 4x = x - 4 becomes...
-x² + 3x + 4 = 0 (subtract x and add 4 to both sides)
x² - 3x - 4 = 0 (divide both sides by -1, we want the x² term to be positive)
(x - 4)(x + 1) = 0 (factor)
so
x - 4 = 0, then x = 4
and
x + 1 = 0, then x = -1
No because 26 isn’t in the multiples of three
Since there are 16 oz in a pound. 1/16 would equal an oz
