He needs 160 5-star reviews in a role. We can write a function to solve this problem. His current total stars is 4.4*160=704. Suppose he needs x more 5-star reviews, then his total stars will be 704+5x. 160+x is the new number of reviews, and the new average will be 4.7, so 4.7*(160+x)=704+5x. The solution is 160. Besides, if you want to get the answer really fast, you can see that 4.7 is right in the middle of 4.4 and 5, so you can immediately guess that the number of new 5-star reviews should be equal to the number of current reviews.

Answer:
option d. 30%
Step-by-step explanation:
Data provided in the question:
Now,
The probability density function of the uniform distribution is given as:
Therefore,
The required probability will be

or
= 0.3 × 100%
= 30%
Hence,
The answer is option d. 30%
I am inclined to think that it is A. or B. Because they represent the highest probability, if it is not those it might be D.
This probably didn’t help, but if it did. I am glad (╹◡╹)
