Answer:
Option: b is correct.
( Stocks have more risk than bonds, but offer more return).
Step-by-step explanation:
Bonds are debts while stocks are stakes of ownership in a company.
Bonds pay a fixed rate of interest, and guarantee principal payment at the end of the term, they're generally considered to be safer than stocks. That doesn't mean bonds are 100% safe.
<em>" Most investment professionals consider bonds a safe component of portfolios. They're supposed to provide the stability and certainty that stocks can't "</em>
<em>" In bond we have a fixed interest whereas in stock the rates could go much high "</em>
Hence, option b is correct. ( Stocks have more risk than bonds, but offer more return).
40 mph
First you have 1200/30. You are trying to get to 1 hour, so in order to get 30 to one, you must divide 30 by 30 and 1200 by thirty as well. You get 40 miles per hour.
Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_
, where 
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :
[Round to next integer.]
Hence, the required minimum sample size = 18
Answer:
Darlene bought more fabric
Darlene bought 3.4 yards more
Step-by-step explanation:
Darlene = 7 yards + 20% extra
= 7 yards + (20% of 7 yards)
= 7 + (20% × 7)
= 7 + (0.2 × 7)
= 7 + 1.4
= 8.4 yards
Chris = 4 yards + 25% of 4 yards
= 4 yards + (25% of 4 yards)
= 4 + (25% × 4)
= 4 + (0.25 × 4)
= 4 + 1
= 5 yards
Darlene bought more fabric
How much more?
Darlene - Chris
= 8.4 yards - 5 yards
= 3.4 yards
Darlene bought 3.4 yards more
