Roman buys seed packets for the school garden. One packet of radish seeds costs $1. 75. One packet of tomato seeds costs $2. 50.
bezimeni [28]

Roman may buy 23 tomato and 9 radish,  for the school garden.

 

<h3><u>Calculation:</u></h3>

Let (r) represent the cost of one packet of radish seeds, and

Let (t) represent the cost of one packet of tomato seeds.

Amount spent by roman = $62.75

It denotes that;

\ 1.75r +2.5t = 62.75.......equn. 1

Roman bought 32 packets of seeds and one packet of radish seeds costs = $ 1.75.

One packet of tomato seeds costs =  $ 2.50.

It denotes that,

\ r+t=32.....equn.2

Substitute t=9 , and r= 23, we have

In eq. 1

\ = 1.75\times9 + 2.5\times23 = 62.75\\ = 15.75+57.5 \neq  62.75 \\ = 62.75 = 62.75

In eq.2

\ =32=23+9 = 32\\

Here, both the equations are satisfied, therefore, option [C] is correct.

Neporo4naja [7]

Answer:

a person was able to invest 1,000 per month for 30 years with interest rate of 5%. 1. find out how much the person will have in
sveticcg [70]

Answer:

1.  $832,258.64

2. $616,550.50

3. $476,407.77

Explanation:

As the question is concerned, we are to calculate the Future value for the following data

1. PV = 0

PMT = 1,000

N = 30*12 = 360

I = 5%/12

Future Value = PV (PMT, N, I)

Future Value =  PV(0, 1,000, 360,0.05/12)

Future Value =  $832,258.6354

Future Value =  $832,258.64

2.   PV = 0

PMT = 1,500

N = 20*12 = 240

I = 5%/12

Future Value = PV (PMT, N, I)

Future Value = PV  (0, 1,500,240, 0.05/12]

Future Value = 616,550.5028

Future Value = $616,550.50

3.  PV = 0

PMT = 800

N = 25*12 = 300

I = 5%/12

Future Value = PV (PMT, N, I)

Future Value =  PV (0, 800, 300, 0.05/12]

Future Value = 475,407.7668

Future Value = $476,407.77

Stolb23 [73]

Answer: A portfolio containing 30 randomly selected stocks will have the smallest standard deviation.

Explanation:

A portfolio containing 30 randomly selected stocks tend to have a lesser covariance between the security returns. Also, there will be increased diversification. This increased diversification lowers the risk of portfolio thereby resulting in a lower standard deviation.

Other options are not correct. A portfolio consisting of 30 energy stocks will have a higher level of covariance between the security returns. Therefore, the standard deviation is lower.

A coefficient of variance greater than one will have a high level of variance while a coefficient variance less than 1 has a lower level of variance. A lesser covariance will result to a lower standard deviation and vice-versa.
