Q. A drone is flying at a height of 50 meters. If the angle of depression from the drone to a point on the ground is 60 degrees, how far is the point from the base of the drone's vertical line?
Q. A family has 3 children. What is the probability that at least one of them is a girl?
A.
1/8
B.
1/4
C.
3/4
D.
7/8
Solution
The only scenario where there are no girls is if all are boys. The probability of all boys is (1/2)^3 = 1/8. Therefore, the probability of at least one girl is 1 - 1/8 = 7/8.
Q. A family has 4 members with an average age of 25 years. If the youngest member is 10 years old, what will be the average age if the youngest member turns 20?
A.
26
B.
27
C.
28
D.
29
Solution
Total age of family = 4 * 25 = 100. New total age after youngest turns 20 = 100 - 10 + 20 = 110. New average = 110 / 4 = 27.5, approximately 27.
Q. A family has 4 members with an average age of 30 years. If a new member joins the family, making the average age 32 years, what is the age of the new member?
A.
32
B.
34
C.
36
D.
38
Solution
Total age of 4 members = 4 * 30 = 120. Total age of 5 members = 5 * 32 = 160. Age of new member = 160 - 120 = 40.
Q. A family has 4 members with an average age of 30 years. If a new member joins with an age of 40 years, what will be the new average age?
A.
30
B.
32
C.
34
D.
36
Solution
The total age of the family is 4 * 30 = 120 years. Adding a new member aged 40 gives a new total age of 120 + 40 = 160 years. The new average age is 160 / 5 = 32.
Q. A flagpole is 12 meters high. If a person standing 16 meters away from the base of the flagpole sees the top of the flagpole at an angle of elevation of θ, what is tan(θ)?
Q. A flagpole is 12 meters tall. If a person standing 16 meters away from the base of the flagpole sees the top of the flagpole at an angle of elevation of θ, what is tan(θ)?
Q. A flagpole is 20 meters tall. If a person is standing 15 meters away from the base of the flagpole, what is the angle of elevation to the top of the flagpole?
Q. A flagpole is 20 meters tall. If a person standing 15 meters away from the base of the flagpole looks up at an angle of elevation of 53 degrees, what is the height of the flagpole?
Q. A flagpole is 20 meters tall. If a person standing 15 meters away from the base of the flagpole sees the top of the flagpole at an angle of elevation of θ, what is sin(θ)?
Q. A flagpole is 20 meters tall. If a person stands 15 meters away from the base of the flagpole, what is the angle of elevation to the top of the flagpole?
Q. A group of 6 people has an average weight of 70 kg. If one person weighing 80 kg leaves, what is the new average weight?
A.
68
B.
69
