Answer:
r = 6
Step-by-step explanation:
To get the value of r we will use the pythagoras theorem a shown;
PR² = QR² + PQ²
(4+r)² = 8² + r²
Expand
16+8r+r² = 64 + r²
16 + 8r = 64
8r = 64 - 16
8r = 48
r = 48/8
r = 6
Hence the value of r is 6
The answer is 75 and here's why.
Let's figure out the amount of remaining votes to prove this.
250 total votes - 150 votes for candidate a = 100 votes.
minus ↑ sign
Candidate B received 25% of the votes, so let's find<u> 25% of 100</u>
<u>100 * 0.25 = 25 votes</u>
Candidate B only got 25 votes (that's kinda sad, poor guy)
<u>100 - 25 votes = the # of votes candidate C got </u>
Candidate C got 75 votes!

Step-by-step explanation:
Let X the random variable that represent the amounts of nocatine of a population, and for this case we know the distribution for X is given by:
Where 
and 
We have the following info from a sample of n =37:
the sample mean
And we want to find the following probability:
And we can use the z score formula given by;
And if we find the z score for the value of 0.872 we got:
And we can find this probability to find the answer:
And using the normal standar table or excel we got:
