Bruh im shook this question is confusing me to kween stage level 1000000
42.09$ would be the correct answer, you just multiple 3.45 and 12.2 to get this answer
Answer: yes, it is valid
Step-by-step explanation:
Given the following probability distribution :
X ________f(x)
100,000___ .10
200,000__ .20
300,000 __ .25
400,000 __ .30
500,000 ___.10
600,000 ___.05
To examine the validity of the distribution :
Each individual observation or point must have probability value in within the range (0 < p ≤ 1)
Where p = probability value.
The sum of the individual probabilities must add up to 0
(0.1 + 0.2 + 0.25 + 0.3 + 0.1 + 0.05)
= 1
Since the two consitions are meet, then, the probability distribution is valid
If the cos A = .83 then the arc cosine of .83 equals the angle
arc cosine (.83) = 33.901 degrees
Similarly, we look up the arc cosine of .55
arc cosine (.55) = 56.633 degrees
NOW we can look up the sine of 33.901 degrees and find it is the
sine of A and it equals 0.55776
the sine of 56.633 degrees = 0.83516 and that is the sine of B
