Answer:
b = 8√3 mm, a = 16 mm, x = 5 ft, y = 5√2 ft.
Step-by-step explanation:
With 30° 60° 90° triangles, one side will be a number, the other leg will be that number multiplied by √3, and the hypotenuse will be 2 times that original number.
So in this case:
The original leg's length is 8 mm. Side b will be that 8 times √3.
So, b = 8√3 mm.
Side a will be 8 times 2.
So, a = 16 mm.
With 45° 45° 90° triangles, the two legs will be the same length, and the hypotenuse will be that number times √2.
So in this case:
The original leg's length is 5 ft. Side x will be that same length.
So, x = 5 ft.
Side y will be 5 times √2.
So, y = 5√2 ft.
Answer:
Step-by-step explanation:
An urn contains two blue balls (denoted 
) and three white balls (denoted 
).
In the selection, a ball is picked and replaced.
From the attached probability tree, the possible outcomes are:
(a)If the first ball drawn is blue
Number of Outcomes =10
The probability that the first ball drawn is blue 
(b)If only white balls are drawn
Number of Outcomes =9
Probability that only white balls are drawn
