Answer:
The answer is 2 1/2 or in mixed form 5/2
Hope I helped :)
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
If you would like to know what percent of 100 is 30, you can calculate this using the following steps:
x% of 100 is 30
x% * 100 = 30
x/100 * 100 = 30
x = 30%
The correct result would be a. 30%.
Answer:
14x
Step-by-step explanation:
7 x 2 = 14
since we are multiplying 2x by 7 its 14x
The money was paid at an annual interest of 261.42%
Explanation:
- The initial amount of the guitar when it was loaned was $960. After a month the guitar cost $1,170. This means that in one month the price went from $960 to $1,170. Increase in cost = Difference between two costs = $1,170 - $960 = $210.
- To convert this into a percent we divide the difference in value by the original price and multiply the answer with 100 to convert it into a percentage. % increase in cost = difference between two costs / original cost % increase in cost = ($210 / $960) * 100 = 0.21785 * 100 = 21.785%
- This 21.875% was the monthly interest that was paid. To convert it into annual interest rate we multiply it with the 12 months.
- Annual interest rate = monthly interest rate * 12 = 21.785% * 12 = 261.42%. This means if the guitar was loaned for a year, you would have to pay $3469.44.
