Answer:
A = 189 sq units
Step-by-step explanation:
You can cut the shape up into pieces. See image. There are two rectangles and a triangle. Some sides are given:
rectangle: 16 × 8
sm rectangle: 3 × 4
Some sides you have to add to find (the height of the whole entire thing: 16+4+4)
Some lengths you have to subtract to find (height of the triangle: 24 - 10).
Area of a rectangle:
length × width OR
base × height
Area of a triangle:
1/2 • b • h
Add up all three areas. See image.
Answer:
Step-by-step explanation:
The signs of the coefficients of the given terms are ...
+ - + -
There are three sign changes, so the number of positive real zeros is 3 or 1.
When odd-degree terms have their signs changed, the signs become ...
- - - -
There are no sign changes, hence no negative real zeros.
_____
A graph confirms this evaluation.
Using the Poisson distribution, it is found that there is a 0.507 = 50.7% probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours.
<h3>What is the Poisson distribution?</h3>In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
The parameters are:
Considering the average of 15 birds every 2 hours during daylight hours, the mean for a 45-minute period is given by:
The probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours is given by:
In which:
Then:
0.507 = 50.7% probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours.
