Answer:
p = 0.68 and p^ = 0.6
Step-by-step explanation:
Jackie received 68% of the votes in an election.
Here p is the decimal equivalent of 68 %.Hence ,
p = 0.68
Now we have taken a sample of 30 people from the total number of voters and we have to find the percentage of votes that Jackie gets in this .
Out of 30 people Jackie got 18 votes. Hence,
p^ = = 0.6
Hence the values are
p = 0.68 and p^ = 0.6
In the random sample we have taken the probability of Jackie has decreased but it will be compensated by another sample where it will be more.
Hello!
A regular pentagon has a sum of 540 degrees, and a pentagon has 5 angles.
To find each angle, we divide 540 by 5 to get 108 degrees.
So therefore, if a pentagon is a regular pentagon, then the measure of each interior angle is 108 degrees.
8 × 22 + 52 × 4
176 + 208
384
this will be your answer
i hope this help
