Answer:
28.36°
Step-by-step explanation:
The problem represents a right angled triangle as shown in the diagram below.
The length of the handicap ramp is 25 feet.
The side ground distance covered by the ramp is the adjacent of the angle of the triangle and it is 22 feet.
To find the angle of elevation of the incline, we apply SOHCAHTOA:
cos θ = adj / hyp
Therefore:
The angle of elevation of the incline for the handicap ramp is 28.36°.
Answer:
Probability (A sum of 10)=0.1025
Step-by-step explanation:
To find the Probability the sum is 10, we can either have
i. a 4 and a 6
ii. a 5 and a 5
Pr (A AND B) = Pr (A) x Pr(B)
Pr (A OR B) = Pr (A) + Pr(B)
Probability (A sum of 10) = Pr(getting a 4 AND a 6) OR Pr(getting a 5 AND a 5)
=(0.25 x 0.25)+(0.20 x 0.20)
=0.0625+0.04
=0.1025
