Zielflug [23.3K]

Answer:

$85,734

Step-by-step explanation:

We have been given that Karel sells goods to customers in exchange for a $100,000 non-interest-bearing note due in 2 years. The interest rate on this type of loan is 8%. We are asked to find the present value of the note.

PV=FV\frac{1}{(1+r)^n}, where,

PV = Present Value,

FV = Future Value,

r = Interest rate in decimal form,

n = Time

Let us convert given interest rate into decimal form as:

8\%=\frac{8}{100}=0.08

PV=100,000*\frac{1}{(1+0.08)^2}

PV=\frac{100,000}{(1.08)^2}

PV=\frac{100,000}{1.1664}

PV=85733.882030

PV\approx 85,734

Therefore, the present value of the note is $85,734.

The line passes through points (0,0) and (7,4)

Gradient = (y2-y1)/(x2-x1) = (4-0)/(7-0) = 4/7

Bob's password consists of a non-negative single-digit number followed by a letter and another non-negative single-digit number
maw [93]

9/20 is the probability that Bob's password consists of an odd single-digit number followed by a letter and a positive single-digit number

It is given that bob's password consists of a non-negative single-digit number followed by a letter and another non-negative single-digit number (which could be the same as the first one).

P (odd single digit number )  =  ( 5 odd single digits / 10 non-negative single digits)  = (5/10)  = 1/2

P (positive single digit number ) =  (9 positive single digits / 10 non-negative single digits)  = 9/10

The total probability is   (1/2) (9/10)  =  9/20
