Answer:
In the word “PROBABILITY”
Total number of letters =11
Number of vowels (o, a, i, i) = 4
Thus, the required probability = 4/11
so they spent 1 hour at practice. They ended at 4:15.
The answer is
K= 2.57
T= -5.74
The polar coordinate of any point can be written as:
(r, θ) = (r, θ + 2nπ) when positive
(r, θ) = [ - r, θ + (2n + 1)π ] when negative
The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).
When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)
When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.
Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].
Area=1/2 times bas time height
base=10
height=12
area=1/2 times 10 times 12
area=5 times 12
area=60 in^2
