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
Answer:
20/28.
Step-by-step explanation:
We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28. We have. 21/28 - 1/28 = (21-1)/28
Answer:
The answer is 15 people.
Step-by-step explanation:
If one fifth is bringing candy and three fifths is bringing dessert than that already four fifths of the people who aren't bringing punch so one fifth of the people are bringing punch so one fifth of 75 is equal to 15
Slope intercept formula: y = mx + b where m equals slope and b equals the y-intercept.
Answer: y = -6x + 3
Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = 
, thus
tan30° = 
= 
and
= ( cross- multiply )
b = 7
