Answer:
Probability that one or more people in Arbalest got a cold is 0.9987.
Step-by-step explanation:
We are given that according to a report, 11 people got colds for every 2000 people.
There are 1200 people in the town of Arbalest.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 1200 people
r = number of success = one or more people got a cold
p = probability of success which in our question is probability
that people got colds, i.e; p = = 0.55%
Let X = <u><em>Number of people in Arbalest who got a cold</em></u>
So, X ~ Binom(n = 1200 , p = 0.0055)
Now, Probability that one or more people in Arbalest got a cold is given by = P(X 1)
P(X 1) = 1 - P(X = 0)
=
=
= 0.9987 or 99.87%
Hence, the required probability is 99.87%.
Answer:
Step-by-step explanation:
We can break the composite figure into two triangles and two trapezoids. The area of a triangle is given by and the area of a trapezoid is given by
(average of the bases multiplied by the height).
Area of first triangle (larger triangle to the figure's left):
Area of second triangle (smaller triangle to the figure's right ):
Area of first trapezoid (smaller trapezoid directly underneath second triangle and adjacent to both triangles):
Area of first triangle (larger triangle to the figure's left):
Thus, the area of the entire figure is:
