Answer:
a
b
Step-by-step explanation:
Let the random X variable representing the 6 companies that give 4 weeks of vacation after 15 years of employment:
-let p=0.5 be the probability of vacation. Since the companies are independent, X assumes a binomial random variable:
#Probability that the number of companies that give vacation is anywhere from 2 to 5:
We use equation 1;
Hence the probability that between 2 and 5 companies give vacation is 0.875
b. The probability that fewer than 3 companies give vacation is calculated as:
From equation one we get:
Hence the probability that less than three companies give vacation is 0.3432

Make the two fractions have common denominators. 9 and 12 both fit into 36, so multiply
the top and bottom of
by 4 and
by 3.

⇒
Now that both fractions have common denominators, you can subtract them easily. Subtract the numerators (8 - 21) and keep the denominators the same.

Answer:
$15 827
Step-by-step explanation:
The formula for the amount A of depreciation of an asset by an annual percentage rate is
A = V(1 - r)ⁿ
where
n = number of years
r = annual percentage rate
V = value
Data:
n = 13 yr
r = 9 %
V = $22 400
Calculations:
A = 22 400(1 - 0.09)¹³ =22 400(0.91)¹³ = 22 400 × 0.293 45 = $ 6573
So, the car lost $6573 in value because of depreciation.
Current value = 22 400 - 6573 = $15 827
