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:
no
Step-by-step explanation:
y=mx+b
applied to the information given:
3y=x+6,
divide both sides by 3
y=1/3x+2
slope is 1/3
All the sides of a proper rectangle are 90 degrees.
<span>So you use sine and cosine to figure out the two different lengths of sides ( because rectangle sides are parallel). To find area you times the two sides together. To find perimeter you times the two sides by two and add them together.</span>
Answer:
Area = 3x^2 +x -14 units^2
Step-by-step explanation:
Area of a rectangle is (width x height)
Area = (x-2)*(3x+7)
Area = 3x^2 +x -14
Multiply 5 and £14.06 to get £70.30 this is your answer
