Answer: 0.21
Step-by-step explanation:
Let A denotes the event that employees are college graduates.
B denotes that the event that employees have more than ten years of experience.
As per given , we have
P(A)=0.51
P(B)=0.47
P(A∪B)=0.77
We know that ,
Hence, the probability that a randomly selected employee will have more than ten years of experience and be a college graduate = 0.21
The height of the ground from the base of the window is 144 inches.
<h3>How to find the side of a right angle triangle?</h3>One angle of a right angle triangle is equals to 90 degrees.
Therefore, the sides and angles of the right triangle can be found using trigonometric ratios.
tan x = WY / XY
tan x = opposite / adjacent
tan x = 24 / 8
x = tan⁻¹ 3
x = tan⁻¹ 3
x = 71.5650511771
x = 71.60°
tan 71.60 = h / 48
cross multiply
h = 48 tan 71.60
h = 48 × 3
h = 144 inches
