9 out of the 15 runners completed the time trial between 52.0 and 53.9 seconds so 9/15 is the percentage you are trying to find. If you divide 9 by 15 and then multiply the decimal by 100, you will have your percentage.

The answer is 60% because there are 9 people who got in between 52.0 and 53.9 seconds and 15 people total in that chart. We can turn this to a fraction 9/15. When we divide 9 and 15 we get .6 and we multiply that by 100 (percents are out of 100) and we get 60%

salantis [7]

Answer:

option B

Step-by-step explanation:

given,                                              

3-month T-bill currently yields  = 3%          

customer price have been rising = 2% rate

Ai Lun's estimate of the real rate = ?            

real rate return                                                  

                       = \dfrac{1 + risk\ free\ rate}{1 +inflation\ rate} - 1

                       = \dfrac{1 + 0.03}{1 +0.02} - 1

                       = \dfrac{1.03}{1 .02} - 1

                       = 1.0098 - 1

                       = 0.0098

                       = 0.98 % ≅ 1 %

hence, the correct answer is option B
