Answer:
D. 70.53
Step-by-step explanation:
To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:
In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.
Substitute,
Simplify
Inverse operations,
Compute,
m<CBA = 70.53
Answer:
0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.
Step-by-step explanation:
For each player, there are only two possible outcomes. Either it is defective, or it is not. The probability of a player being defective is independent of any other ray. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Five percent of all blue ray players manufactured by a large electronics company are defective.
This means that 
A quality control inspector randomly selects three players from the production line.
This means that 
What is the probability that exactly one of these three blue ray players is defective?
This is P(X = 1). So
0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.
The answer is 35 so that's it
Answer:
Mean: 52.8
Median:52
Mode:54
Step-by-step explanation:
Mean: 54+48+37+55+51+54+42+52+53=476
476/9=52.8
Median: 37,42,48,51,52,53,54,54,55. The middle one is 52.
Mode: Most common one = 54
Hope this helps! Have a nice day!
Step-by-step explanation:
Hi,
I agree with what you did. You could also add y on both sides and get 3x = y + 5 and then divided by three to get...
x = 5 + y /3
(the 5 and y are being divided by 3)
But that's just complicated, it works, but it's complicated. What you did is correct and what I gave you is the value of x, but I'm 100 percent sure yours is correct.
Hope this helps
