Answer:the probability that exactly five customers make a purchase is 0.033
Step-by-step explanation:
The formula for binomial distribution is expressed as
P(x = r) = nCr × q^(n - r) × p^r
Where
p = probability of success
q= probability of failure
n = number of sample
From the information given,
39 percent of all customers who enter a store will make a purchase. It means that the probability of success, p = 39/100 = 0.39
The probability of failure q, would be 1 - p = 1 - 0.39 = 0.61
n = 6
The probability that exactly five customers make a purchase is expressed as
P(x = 5) = 6C5 × 0.61^(6 - 5) × 0.39^5
P(x = 5) = 6 × 0.61× 0.39^5 = 0.033
Answer:
640.919 feet
Step-by-step explanation:
Given that there is an antenna on the top of a building. From a location 400 feet from the base of the building, the angle of elevation to the top of the building is measured to be 37°. From the same location, the angle of elevation to the top of the antenna is measured to be 40°
Let the height of building be x and that of antenna be y.
Then by considering right angle formed by horizontal line, vertical height and line made by eye contact we have
Next considering the height with antenna included we get total height
The correct answer is option A which is the distance between A and D will be AD = .
<h3>What is coordinate geometry?</h3>
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
The formula utilised to find the distance between two points is;-
X =
We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.
AD = .
Therefore the correct answer is option A which is the distance between A and D will be AD = .

Congruent means that the measures of both triangles are the same or in other words the corresponding sides and angles equal each other. The measurements will be the same. Here, bc corresponds to fg(gf), ab to ef and ac to eg. This means that those sides have equal measures or in other words equal each other. BC=8 as GF equals 8 other two sides, EF=6 as AB equals 6 and the same thing for the last side EG=10 as AC equals 10. Hope this helps.
