The answer is below.

Explanation:

The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

a) Given that n = 100, μ = 2000, σ = 18

For x < 1995 millimeters:

$z=\frac{x-\mu}{\sigma/\sqrt{n} }=\frac{1995-2000}{18/\sqrt{100} } =-2.78$

From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027

b) P(z > z*) = 10% = 0.1

P(z < z*) = 1 - 0.1 = 0.9

z* = 1.28

$z*=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\1.28=\frac{x-2000}{18/\sqrt{100} }\\\\x-2000 =-2.304\\\\x=2002.3\ ml\\\\$

From the normal distribution table, P(z < z

A bond with 15 detachable warrants has just been offered for sale at $1,000.00 . The bond matures in 25 years and pays a semi-an

ad-work [718]

Answer:

$15.64

Explanation:

first we must determine the market value of the bond without the warrants:

PV of face value = $1,000 / (1 + 3.5%)⁵⁰ = $179.05

PV of coupon payments = $25 x 23.45562 (PV annuity factor, 3.5%, 50 periods) = $586.39

market value = $765.44

the market value of the 15 warrants = $1,000 - $765.44 = $234.56

market value per warrant = $234.56 / 15 = $15.64

podryga [215]

Answer:

$137,200; $103,600

Explanation:

In 2015:

Free cash flow:

= Net cash flow from operating activity - Capital expenditure

= $294,000 - (70% × $224,000)

= $294,000 - $156,800

= $137,200

In 2016:

Free cash flow:

= Net cash flow from operating activity - Capital expenditure

= $280,000 - (70% × $252,000)

= $280,000 - $176,400

= $103,600
