K=9S/2, total savings is S+9S/2=11S/2. So 9S/2÷11S/2=9/11. (a) The ratio is 9:11.
(b) Kieran’s savings are 9/11 of the total savings.
(c) Simon’s savings are S÷11S/2=2/11 of total savings (or simply subtract 9/11 from 1).
(d) K-S=28, 9/11-2/11=7/11 of the total savings, so 7/11 of the total savings is $28 and total savings is 11/7×28=$44.
CHECK
Kieran has 9/11 of $44 which is $36 and Simon has $8. 36/8=9/2 so the ratio is correct.
Simon has $28 less than Kieran and 36-8=28, which is correct.
Had to look for the missing options and here is my answer.
Based on the study being conducted by Miranda which was covers students who would attend a students only school dance, the sample that is most likely going to give a representative sample for the poll would be "<span>twenty names from each grade pulled blindly from a container filled with the names of the entire student body </span><span>written on slips of paper." Hope this helps.</span>
Answer:
12x + 15y
Step-by-step explanation:
3 x 4x= 12x
3 x 5y = 15y
Answer:
0.02 or 2% = Beta
Step-by-step explanation:
Given that,
Risk-free rate = 7 percent
Expected return on the market = 10 percent
Expected return on Security J = 13 percent
Therefore, the beta of Security J is calculated as follows;
Expected return on Security J = Risk-free rate + Beta (Expected return on the market - Risk-free rate)
13 percent = 7 percent + Beta (10 percent - 7 percent)
0.13 - 0.07 = 0.03 Beta
0.06 = 0.03 Beta
0.06 ÷ 0.03 = Beta
0.02 or 2% = Beta
Answer:
n = log(
)
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent.
