Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2 feet. What is the total length
1 answer:
Answer:
110 feet
Step-by-step explanation:
Given that,
Length of the rectangular garden = 9 1/4 feet = 37/4 feet
Width of the rectangular garden = 4 1/2 feet = 9/4 feet
We need to find the total length of fencing Mark needs to surround all 4 gardens.
The length for 1 garden = perimeter of the garden
The length for 4 garden = 4×perimeter of the garden
= 4×2(l+b)
Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.

From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:
Now, since interior angles of any triangle add up to 180 degrees, we have
By combining similar terms, we get
Then, x is given as
Therefore, the answer is x=90 degrees
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%.
