Jennifer's January finance charge will be $0.6717 more if it is calculated using the previous balance method.

<h3>what is the difference between the previous balance method and the adjusted balance method?</h3>

Previous balance method: Interest charges are based on the amount owed at the beginning of the previous month's billing cycle.

Adjusted balance method: Bases finance charges on the amount(s) owed at the end of the current billing cycle after credits and payments have been posted.

the total amount on which interest will be applied using the previous balance method = 807.94+41.81+75+18.65 = $943.4

so, interest levied on this= 943.4*10.22*(30/360)*(1/100)= $8.0346

now, the total amount on which interest will be applied using the adjusted balance method = 807.94+41.81+75+18.65-53.88-25 = $864.52

so, interest levied on this = 864.52*10.22*(30/360)*(1/100)= $7.3628

difference between charges by previous balance method and adjusted balance method = 8.0346-7.3628 = $0.6717

therefore, Jennifer's January finance charge will be $0.6717 more if it is calculated using the previous balance method.

There are 5 radar stations and the probability of a single radar station detecting an enemy plane is 0.55. What is the probabili
Lerok [7]
This is a binomial distribution with n = 5, p = 0.55, q = 1 - 0.55 = 0.45, x = 0, 1, 2, 3

P(x) = nCx p^x q^(n - x)
P(x ≤ 3) = 1 - P(x > 3) = 1 - [P(4) + P(5)]
P(4) = 5C4 x (0.55)^4 x (0.45) = 0.2059
P(5) = 5C5 x (0.55)^5 x 1 = 0.0503

P(x ≤ 3) = 1 - (0.2059 + 0.0503) = 1 - 0.2562 = 0.7438

The heights of American men are normally distributed. If a random sample of American men is taken and the confidence interval is
solmaris [256]

Answer:

<h2>69.5</h2>

Step-by-step explanation:

Given the confidence interval of the heights of american heights given as (65.3,73.7);

Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7

Sample mean will be the average of both confidence interval . This is expressed mathematically as \overline x = \frac{L+U}{2}

\overline x = \frac{65.3+73.7}{2}\\\overline x = \frac{139}{2}\\\overline x = 69.5

Hence, the sample mean is 69.5

PLEASE HELP PLEASE

The x-coordinate in the solution of the system of equations  y = -2/3x and 4x - 9y = -40 is -4

<h3><u>Solution:</u></h3>

<em><u>Given that system of equations are:</u></em>

y = \frac{-2}{3}x  ------- eqn 1

4x - 9y=-40 ------ eqn 2

We have to solve the above given system of equations and find the x - coordinate

<em><u>Substitute eqn 1 in eqn 2 and solve for "x"</u></em>

4x - 9(\frac{-2}{3}x) = -40\\\\4x + \frac{18x}{3} = -40\\\\12x + 18x = -120\\\\30x = -120\\\\x = \frac{-120}{30} = -4

x = -4

Thus the x-coordinate in the solution of the system of equations is -4

The area of circular garden is 530.66 feet2. What is the circumference of the garden? (Use 3.14 for .)
adelina 88 [10]

Answer:

The answer to your question is Circumference = 81.64 ft

Step-by-step explanation:

Data

Area of a circle = 530.66 ft²

Circumference = ?

π = 3.14

Process

1.- Calculate the radius of the circle

Area = πr²

-Solve for r²

  r² = Area / π

-Substitution

  r² = 530.66 / 3.14

-Simplification

  r² = 169

-result

  r = 13 ft

2.- Calculate the Circumference      

Circumference = 2πr

-Substitution

Circumference = 2(3.14)(13)

-Result

Circumference = 81.64 ft
