Answer:

(B) Statistic

Explanation:

A statistic is defined as a metric derived from (or that describes) a sample. As such, given a certain population (in the case of the question, <em>the population is the total number of new engines developed by the company</em>), a sample can be selected from the population (<em>the sample in the question is the 100 engines that are randomly selected</em>).

Any characteristic that describes the population is known as a parameter, whereas a characteristic that defines the sample is a statistic. In the question given, the average lifetime of 11 years was derived from the sample of 100 engines as is thus a statistic.

You need a 35-year, fixed-rate mortgage to buy a new home for $340,000. Your mortgage bank will lend you the money at an APR of
grin007 [14]

Answer: $338712.36

Explanation:

Given the following :

APR = 6.35% = 0.0635

Monthly payment = $1800

Cost of home = $340,000

Period (t) = 420

Monthly rate = 0.0635 / 12

Amount paid on loan = PV of monthly payment :

PMT(1 - (1 / (1 + r)^t)) / r

1800[(1 - (1 / (1 + 0.0635/12)^420)) / r]

1800[ (1 - (1 /9.1764488)) / r

1800[ 1 - 0.1089746] / (0.0635 / 12)

1800 [168.38275]

= $303088.95

Hence, amount yet to pay :

$340,000 - $303088.95 = $36911.05

Hence, balloon payment :

36911.05( 1 + r)^t

36911.05(1 + 0.0635/12)^420

36911.05(1 + 0.0052916)^420

36911.05(1.0052916)^420

36911.05 × 9.1764488

= $338712.36

If your budget allowed you extra money for this month, would you choose to consume, invest, or save that money? Why? Be specific
ruslelena [56]
Personally, I would choose to save that money. The reason why is you never know - maybe something bad is going to happen and you will need that extra cash. So instead of splurging it on material things, it's better to save it for a rainy day, in my opinion. Investing is not safe, given that you may lose a lot more than you invest.

Explanation:

Giving the following information:

First-quarter budgeted jump rope sales in units 23,000

Inventory at the beginning of the year was 3,600 jump ropes.

Totz Company wants to have 10​% of the next​ quarter's sales in units on hand at the end of each quarter.

Sales budget= sales for the quarter + ending inventory - beginning inventory

1st quarter:

Sales budget= 23,000 + (70,000*0.10) - 3,600= 26,400 units
