we are given
basketball player Chauncey Billups of the Detroit Pistons makes free throw shots 88% of the time
so, probability of making shot is
=88%
so, p=0.88
To find the probability of missing first shot and making the second shot
so, we can use formula
probability = p(1-p)
now, we can plug values
we get
So, the probability that he misses his first shot and makes the second is 0.1056........Answer
Answer:
Value of a ( Length of BC) = 16.4925cm
Step-by-step explanation:
Given: In right Δ ABC, m∠B = 90°, and m∠A = 30° and Hypotenuse AC = 32.9848450049 cm.
To find: Length of BC (value of a) = ?
Sol: In right Δ ABC,
m∠A + m∠B + m∠C = 180° ( sum of angles of a triangle)
30° + 90° + m∠C = 180°
m∠C = 180° - 120° = 60°
Now Using trigonometry ratios, in right Δ ABC,
(∵ cos 60° = 1/2 and
Therefore, value of a ( Length of BC) = 16.4925 cm.
