99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.

<h3>What is standard deviation?</h3>

Any given quantity, which is used to express that how many observations  differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.

To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,

\rm P(mu-3\ x\ \sigma < X < \mu + 3\ x\ \sigma)

Solving further,

\rm P(176-3\ x\ \12 < X < \176+ 3\ x\  12) = 0.997

Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

Marta_Voda [28]

Answer:

$6,900

Explanation:

The cash flow statement includes three types of activities which are listed below:

1. Operating activities: This involves all transactions that after net income impact the working capital. It would subtract the rise in current assets and a reduction in current liabilities, while adding the decline in current assets and an increase in current liabilities.

It would adjust those changes in working capital. In addition, the depreciation cost is added to the net income, and the loss of asset sales is reduced, while the profit on asset sales is deducted

It also involve cash receipts and cash payments.

2. Investing activities: It tracks operations that include buying and selling long-term properties. The buying is a cash outflow whereas the sale is a cash inflow

3. Financing activities: It tracks transactions that have an impact on long-term debt and equity balance of shareholders. Share issue is a cash inflow while redemption and dividend are cash outflows.

So, the classification and the amount of cash flows is shown below:

a. Issue common stock for cash, $44,000 = $44,000 = Financing activities

b. Purchase building and land with cash, $29,000 = ($29,000) = Investing activities

c. Provide services to customers on account, $6,400 = Not applicable as this transaction does not involve any cash.

d. Pay utilities on building, $700 = ($700) = Operating activities

e. Collect $4,400 on account from customers = $4,400 = Operating activities

f. Pay employee salaries, $8,400. = ($8,400) = Operating activities

g. Pay dividends to stockholders, $3,400.  = ($3,400) = Financing activities

So, the cash flow would be

= $44,000 - $29,000 - $700 + $4,400 - $8,400 - $3,400

= $6,900

Answer:

Hart Corp.'s note should be reported at $10,000

Maxx Inc.'s note should be reported at $7,883

Explanation:

Interest bearing notes that represent current accounts (due within one year) should be reported at face value. Hart Corp.'s note is due in nine months, so it should be reported at = $10,000

Maxx Inc.'s note must be recorded at present value because it is due in 5 years.

FV = $10,000 x 1.03⁵ = $11,592.74

now we must determine its present value using an 8% discount rate:

PV = $11,592.74 x 0.680 = $7,883

West Corp. issued 20-year bonds two years ago at a coupon rate of 8.3 percent. The bonds make semiannual payments. If these bond
lora16 [44]

Answer:

Yield to Maturity (YTM) is 7.94 %.                      

Explanation:

Yield to Maturity (YTM) refers to internal rate of return that bond holder will earn if he purchased the bond today at the current market price and held it till maturity of the bond.

Yield to Maturity of the the bond = [Coupon payment+ (Future value of bond - Present value of bond / no. of Periods)] / [(Future value of bond + Present value of bond)/2] ---- (a)

Bond maturity period = 20 years

Coupon rate = 8.3 %

Par Value = 1000

No. of periods = 2 x 20 = 40 (semi- annual)

Coupon payment = 8.3 % x 1000 = 83 = 83/2 = 41.5 (Semi-annual)

Present value of bond = 104 percent of Par value = 104

Future value of bond = 1000

YTM = ?

Putting the values in equation (a),

Semi annual YTM = [41.5 + (1000-1040 / 40)] / [(1000 + 1040)/2]

Semi annual YTM = [41.5 + (-40/40) ] / [(1040)/2]

Semi annual YTM= [41.5 - 1] / 1020

Semi annualv YTM =  40.5 / 1020 = 0.0397

Hence, Annual yield to maturity = 0.0397 x 2 = 0.0794 or 7.94 %.
