Answer: 6 large frames and 12 small frames
Step-by-step explanation:
We define the following:
x = number of large frames
y = number of small frames
Make the following equations:
x + y = 18
19x + 9y = 222
Use system of equations to solve. We find the value of x first.
y = 18 - x
⇒ 19x + 9(18 - x) = 222
⇒ 19x + 162 - 9x = 222
⇒ 10x + 162 = 222
⇒ 10x = 60
⇒ x = 6
Find value of y:
6 + y = 18
y = 12
∴ 6 large frames and 12 small frames were purchased.
Answer:
Binomial; \mu p=87.5, \sigma p=7.542
Step-by-step explanation:
- a distribution is said be a binomial distribution iff
- The probability of success of that event( let it be p) is same for every trial
- each trial should have 2 outcome : p or (1-p) i.e, success or failure only.
- there are fixed number of trials (n)
- the trials are independent
- here, the trials are obviously independent ( because, one person's debt doesn't influence the other person's)
- the probability of success(0.35) is same for every trial
(35/100=0.35 is the required p here)
[since, the formula for 
]
[since, the formula for [tex]\sigma _{p} =\sqrt{n*(p)*(1-p)}
- therefore, it is Binomial; \mu p=87.5, \sigma p=7.542
Answer:
Option "D" is the correct answer to the following question.
Step-by-step explanation:
Given:
Return on U.S.Treasury bills = 4%
Potential return on stock investment = 10%
Find:
Additional risk of investing in the stock (Risk premium) = ?
Computation:
⇒ Additional risk of investing in the stock (Risk premium) = Potential return on stock investment - Return on U.S.Treasury bills
⇒ Additional risk of investing in the stock (Risk premium) = 10% - 4%
⇒ Additional risk of investing in the stock (Risk premium) = 6%
Reduce 35/100 to 7/20 by dividing both sides by 5.
2/5 is bigger than 7/20.
2/5 > 7/20 or 2/5 > 35/100 if you leave it unsimplified
Hope this helps :)
