Just multiply across:
3 x 5 = 15
8 x 6 = 48
15/48 = 5/16
hope this helps :)
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
= 
= 
= 
= 
= 0.0098
= 0.98 % ≅ 1 %
hence, the correct answer is option B
To get the probability that randomly selected airfare between Boston and San Francisco will be more than $450, we proceed as follows:
the z-score is given by:
z=(x-μ)/σ
thus the z-score for our information will be:
z=(450-387.20)/68.50
z=0.9168
hence our probability will be:
P(X>x)=1-P(z)
P(z)=0.8212
thus
P(X>x)=1-0.8212=0.1788~17.88%
