mrs. white buys a used car for $3,000 she makes monthly payments of $300 until the car is paid for. mr. brown buys a used car fo
Arisa [49]

Answer:

Initial value for Mrs. White is $600 more than Mrs. Brown.

The rate of change is same for both.

Step-by-step explanation:

Cost of car purchased by Mrs. White = $3,000

Rate at which she pays for the car = $300 per month

Cost of car purchased by Mrs. Brown = $2,400

Rate at which she pays for the car = $300 per month

So,

Initial value for Mrs. White was =$3,000

Initial values for Mrs. Brown was =$2,400

difference in initial values  =3000-2400  =$600

∴ Initial value for Mrs. White is $600 more than Mrs. Brown.

Rate of change of payment due for  Mrs. White = $300 per month

Rate of change for payment due for Mrs. Brown = $300 per month

∴ The rate of change is same for both.

Since Mrs White had a higher initial value than Mrs Brown and both having same rates of change, therefore Mrs. White will take a longer time to pay the due.

One option in a roulette game is to bet $12 on red.​ (There are 18 red​ compartments, 18 black​ compartments, and two compartmen
Alona [7]

Answer:

The expected value is -$0,63

Step-by-step explanation:

The expected value of a discrete variable x is given by:

E(x)=x1*p(x1)+x2*p(x2)+...+xn*p(xn)

Where x1, x2, .. xn are the posibles results that the variable x can take and p(x1), p(x2),...,P(xn) are their respective probabilities.

In this case, we have two possible results if we bet $12 on red. This results are:

1. The balls lands on red: in this case we keep the $12 we paid and we awarded 12. That means, we gain $12 and the probability of this case is the division of the number of red compartments by total number of compartments. So:

x1=$12

p(x1)=18/38

2. The balls doesn't land on red: in this case we lose the $12 that we bet and the probability is the division of number of compartments that aren't red by the total number of compartments. So:

x2=-$12

p(x2)=20/38

Then, replacing x1, x2, p(x1) and p(x2) on the equation of the expected value, we get:

E(x)=($12)*(18/38)  +  (-$12)*(20/38)

E(x)=$-0.63

So, the expected value if we bet $12 on red is to lose $0.63

9514 1404 393

Answer:

  0.2807

Step-by-step explanation:

The relationship between the effective annual yield (e) and the nominal annual interest rate (r) compounded n times per year is ...

  e = (1 +r/n)^n -1

  e = (1 +0.25/12)^12 -1 = 0.2807 . . . . . . about 28.07%

Help!? I have to use elimination to solve it btw
anygoal [31]

Answer:

(-4, 5)

Step-by-step explanation:

The problem is a system of equations where you have two variables and can use the method of eliminate (eliminating one of the variables) to solve.  In this case, you will need to multiply one of the fractions by a factor to eliminate a variable.  It seems easiest to multiply the first equation by a factor of -5:

-5(x - 3y) = -24 (distribute) -5x + 15y = 120

Add the equations:

-5x + 15y = 120

<u>+5x + 8y = -5</u>

      23y = 115 (divide by 23)

         y = 5

Solve for 'x':  x - 3(5) = -24 or x - 15 = 24 (add 15) x = -4

Ordered pair: (-4, 5)
