Answer:
B) 0.1487
Step-by-step explanation:
Let
be the discrete random variable that represents the number of events observed over a given time period. If
follows a Poisson distribution, then the probability of observing
events over the time period is:

Where:

#1: 15%
#2: 1/10 = 10%
There are 6 girls who have blonde hair out of 40 students; 6/40 = 15%.
There are 4 boys that have black hair out of 40 students; 4/40 = 1/10 = 10%.
Answer:
π/4 radians
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle (in radians).
Here, r = 8 inches and s = arc length = 2π inches. We need to find the central angle, Ф. The formula given above is s = rФ, or, equivalently,
Ф = s/r.
Here, the central angle is Ф = s/r = 2π/8, or π/4 radians.

Answer: Choice B) -4 < x < 2</h3>
Work Shown:
-1 < x+3 < 5
-1-3 < x+3-3 < 5-3 ... subtract 3 from all sides
-4 < x < 2
