Answer:

The average defective rate of the samples is:

6.3 samples per day

Explanation:

To calculate the average or mean defective rate, we will compute the total number of defective samples, and divide the result by the total number of days. It is important to note that day 7 is ignored during this calculation because there was no defective DNA sample on that day, hence it does not contribute to the average defective samples.

Total Defective DNA sample = 7 + 6 + 6 + 9 + 5 + 6 + 8 + 9 + 1 = 57

Total number of days = 9 ( Days 1 to 6, and 8 to 10).

Therefore, average defective rate = Total Defective DNA sample ÷ Total number of days

= 57 ÷ 9 = 6.3 DNA samples

Lena [83]

Answer:

(B) $38,446,000

Explanation:

Assuming a linear depreciation model, depreciation will occur at the same rate each year. Since the total after 15 years is 90% of the original value, the percentage depreciated per year is given by:

P= \frac{90\%}{15} \\P=6\%

The book value (V) of this purchase after the first year will be:

V=\$40,900,000*(1-0.06)\\V=\$38,446,000

Therefore, the answer is (B) $38,446,000

Daniel deposits $2,000 per year at the end of the year for the next 15 years into an IRA account that currently pays 7%. How muc
diamong [38]

Answer:

$50,258.

Explanation:  

According to the scenario, computation of the given data are as follow:-

We can calculate the deposit amount at the end of 15 years by using following formula:-

Deposit Amount per year(PMT) = $2,000

Interest rate = 7% = 0.07

Deposit year (n) = 15 years

Future value(FVIFA) = PMT × [{(1 + interest rate)^number of years - 1} ÷ interest rate]

= $2,000 × [{(1 + 0.07)^15 - 1} ÷ 0.07]

= $2,000 × [{2.7590315 - 1} ÷ 0.07]

= $2,000 × [1.7590315/0.07]

= $2,000 × 25.129022

= $50,258

According to the analysis total deposit at the end of the year is $50,258.

A 30-year maturity bond making annual coupon payments with a coupon rate of 12% has (Macauley) duration of 11.54 years and conve
dsp73

The price of the bond if the yield to maturity falls to 7%, based on the period and amount will be $1,620.45.

<h3>What is the price of the bond at 7%?</h3>

We shall assume that the bond has a face value of $1,000.

The coupon is:

= 12% x 1,000

= $120

The price is:
= (Coupon x Present value interest factor of annuity, 30 years, 7%) + Face value of bond / ( 1 + rate) ^ number of periods

= (120 x 12.409) + (1,000 / (1 + 7%)³⁰)

= $1,620.45
