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
Note:
Due to my research and findings to this example, the complete question for is attached below, i solved or Question 2(d) only
Set up as a proportion
90/6 = 300/x
multiply 90x=6(300)
90x = 1800
divide both sides by 90
x=20
The solution to your question is x=9
X= 3 because the absolute value makes the -5 a 5. Meaning it will be x+5=8 and then you just solve for x
The answer is System 2 and system 3, because the second equation in system 3 is
obtained by adding the first equation in system 2 to two times the
second equation in system 2, i just took the test.
