Answer:
(B) No. A binomial probability model applies to only two outcomes per trial.
Step-by-step explanation:
The binomial probability is the probability of having 
sucesses on 
repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.
Since in our problem there are three possible outcomes, the binomial probability cannot be used.
The correct answer is (B)
(B) No. A binomial probability model applies to only two outcomes per trial.
Answer:
The area of the circle is 379.94 mm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 11 mm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (11 mm)²
a = 3.14 * 121 mm²
a = 379.94 mm²
Round to the nearest tenth
a = 379.94 mm² = 379.9 mm²
The area of the circle is 379.9 mm²

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
