Answer:
12.57 yards
Step-by-step explanation:
The circumference of a circle is denoted by: , where d is the diameter.
Here, we are given the diameter, so d = 4.
Now, plug this into the equation:
≈ 12.57
The circumference is about 12.57 yards.
Hope this helps!
Answer:
The probability of successful long hit is greater than 0.7083
Step-by-step explanation:
Solution
The expected value for long hit is given below
P (successful hit) * 4.2 + P (Unsuccessful hit) *5.4
so,
= P * 4.2 + (1-p) * 5.4
= 5.4 - 1.2p
Now,
If the expected value of long hit is less than that of the short it
Then,
5.4 - 1.2p <4.55
P> (5.4 - 4.55)/1.2
P> 0.7083
Therefore the probability of successful long hit is greater than 0.7083
