Answer:
B
Step-by-step explanation:
The Pythagoras theorem states that 
, where 
is the hypotenuse and a and b are the adjacent and opposite sides of the hypotenuse. If we made 
the subject of the expression, the expression will be re-written as 
, which is the correct answer.
Answer:
The expected number of hunters who hit the duck they aim at is 3.6
Step-by-step explanation:
Given;
number of hunters, n = 6
the probability of killing a duck, p = 0.6
The expected number of hunters who hit the duck they aim at?
In binomial distribution, the expected value is equal to the product of the number of trials and the probability of success.
The expected number of hunters who hit the duck they aim at is calculated as follows;
E = np
E = 0.6 x 6
E = 3.6
Therefore, the expected number of hunters who hit the duck they aim at is 3.6
Answer:
AD = 2.4
Step-by-step explanation:
All of the triangles in this figure are similar, so their corresponding sides have the same ratios.
The short side of ΔABD is 3/5 of the hypotenuse, which is 4.
AD/AB = CA/CB . . . . = short side/hypotenuse
AD = AB(CA/CB) = 4(3/5) = 2.4
The length of AD is 2.4 units.
_____
You can also go at this in terms of area.
A = 1/2bh = 1/2(3)(4) = 1/2(5)(AD) ⇒ AD = 12/5 = 2.4
It makes a 74 degree angle.
The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.
adjacent/hypotenuse is the ratio for cosine:
cos x = 7/25
To solve this, we will take the inverse cosine:
x = cos⁻¹(7/25) = 73.7 = 74
