Find the present value PV of the given investment. (Round your answer to the nearest cent.) An investment earns 2% per year and

vazorg [7]

Let P = the PV (principal value).

n = 12, the monthly compounding interval
r = 2 = 0.02, the rate
nt = 20 months

The value if $20,000 after 20 months, therefore
P(1 + r/n)²⁰ = 20000
1.0339P = 20000
P = $19,344.86

Answer: PV = $19,344.86

Determine if the equations are intersecting, parallel, or coincident.

aleksandrvk [35]

Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
-ay=-bx+2 
ax+by=3 

Divide each term in the equation by -1a. 
y=(bx-2)/(a) 
ax+by=3 

Divide each term in the numerator by the denominator. 
y=(bx)/(a)-(2)/(a) 
ax+by=3 

The equation is not linear, so the slope does not exist. 
No slope can be found. 
ax+by=3 

Since ax does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ax from both sides. 
No slope can be found. 
by=-ax+3 

Remove the common factors that were cancelled out. 
No slope can be found. 
y=-(ax)/(b)+(3)/(b) 

Divide each term in the equation by b. 
No slope can be found. 
y=(-ax+3)/(b) 

Divide each term in the numerator by the denominator. 
No slope can be found. 
y=-(ax)/(b)+(3)/(b) 

The equation is not linear, so the slope does not exist. 
No slope can be found. 
No slope can be found. 

Compare the slopes (m) of the two equations. 
m1=, m2= 

The equations are parallel because the slopes of the two lines are equal.

A game spinner has eight equal sections: three sections numbered 1, one section numbered 2, and four sections numbered 3. The sp

baherus [9]

Answer:

The required probability is $\frac{1}{8}$ or 0.125

Step-by-step explanation:

Consider the provided information.

The spinner is spin twice and we want the sum should be 5.

We can get 5 if first spin gives us 2 and second spin gives 3.

Or we can get 5 if first spin gives us 3 and second spin gives 2.

There are 8 section out off which Three sections numbered 1, one section numbered 2, and four sections numbered 3.

The probability of getting 2 is $\frac{1}{8}$

The probability of getting 3 is $\frac{4}{8}$

Now, the probability that the sum of the two spins will be five is:

$\frac{1}{8}\times \frac{4}{8}+\frac{4}{8}\times \frac{1}{8} =\frac{4}{64}+\frac{4}{64}=\frac{1}{8}$

Hence, the required probability is $\frac{1}{8}$ or 0.125
