Which of the following is the contrapositive of the following statement: If it is past 5:00 p.m., Megan’s office building is not
scoundrel [369]

Answer:

B

Step-by-step explanation:

A contrapositive statement is one that switches the hypothesis and conclusion of a conditional statement and negates both. In our hypothesis,

"If it is past 5:00 p.m., Megan’s office building is not empty", we shall break it into two statements and show the contarpositive of each like shown below.

Hypothesis                                             Contrapositive

Megan’s office building is not empty- Megan’s office building is empty

It is past 5:00 p.m  - it is not past 5:00 p.m

And thus the contrapositive statement becomes

If Megan’s office building is empty, then it is not past 5:00 p.m.

If the CPI (consumer price index) of 141 increased 8.3 % this year. What was the end of year CPI?
DENIUS [597]

If the CPI increased by 8.3%, therefore this means that there was a fractional increase of 0.083. So amount increased is:

 

CPI increase = 141 * 0.083 = 11.703

 

Therefore the end of year CPI is the sum of the original and the increase:

 

end of year CPI = 141 + 11.703 = 152.703

 

Answer:

152.703
