Using the credit card from question 13,(you have a credit card that has a balance of $3,589.90 and a credit limit of $5,000.) if you have a good credit rating, how much must you pay at the end of the month to get the balance to the acceptable debt ratio percentage
You must pay $2,089.90 at the end of the month to bring the balance to the acceptable debt ratio percentage.
How to determine the amount to payFrom the question, we have the following parameters that can be used in our computation:
Balance = $3589.90
Credit limit = $5000
To determine the acceptable debt ratio percentage, we make use of 30% minimum credit utilization rate.
So, the acceptable balance on the credit card is:
Balance = $5,000 * 30% = $1,500.
Since the current balance is $3,589.90, we have
Payment = $3,589.90 - $1,500
Payment = $2089.9
So, you must pay $2,089.90

suppose that you randomly draw one card from a standard deck of 52 cards. after writing down which card was drawn, you replace the card, and draw another card. you repeat this process until you have drawn 15 cards in all. what is the probability of drawing at least 7 clubs?
The probability of drawing at least 7 clubs in 15 draws from a standard deck of 52 cards is approximately 0.496.
The number of ways to draw 7 or more clubs in 15 draws can be found by using the cumulative distribution function for the binomial distribution. This distribution models the number of successful outcomes (clubs) in n independent trials (card draws), each with the same probability of success (drawing a club). The cumulative distribution function gives the probability of getting a certain number of successful outcomes or fewer.

solve the following systems of linear equations using substitution
6x - y = -7 and 5x + y = -4
Answer:
(-1,1)
Step-by-step explanation:
1. Rearrange either equation to isolate one of the variables. Lets use 6x - y = -7 :
6x - y = -7
-y = -7 - 6x
y = 7+6x
2. Now use this definition of x in the second equation:
5x + y = -4
5x + (7+6x) = -4
11x = -11
x = -1
3. Now use x = -1 in either equation to find y:
6x - y = -7
6 (-1) - y = -7
-y = -1
y = 1
The solution is (-1,1)

Suppose you know that ∠S and ∠Y are complementary and that m∠S = 2(m∠Y) − 30°. Find m∠Y.
Answer:
Step-by-step explanation:
Since ∠S and ∠Y are complementary, we have:
∠S + ∠Y = 90°
We also know that:
m∠S = 2(m∠Y) − 30°
Substituting the second equation into the first equation, we get:
2(m∠Y) − 30° + ∠Y = 90°
Combining like terms:
3(m∠Y) = 120°
Dividing both sides by 3:
m∠Y = 40°
Therefore, m∠Y is 40 degrees.

suppose that the length of a certain rectangle is two centimeters more than three times its width. if the area of the rectangle is 33 square centimeters, find its length and width.
The rectangle measures 6 centimetres in width and 18 centimetres in length.
The rectangle's length is two millimetres longer than its width. As a result, the length (L) is equal to 3(W) + 2, where W is the rectangle's width. Additionally, we are aware that the rectangle (A) has a 33 square centimetre area. In order to find W, we can apply the formula A = L x W. 33 = 3W2 + 2W because it is (3(W) + 2) x W. The quadratic equation can be used to find W, which equals 6. This indicates that the rectangle has a width of 6 centimetres and a length of 3(6)+2=18 cm.

Is (x − 2) a factor of f(x) = x3 − 2x2 + 2x + 3? Use either the remainder theorem or the factor theorem to explain your reasoning.
Answer:
(x - 2) is not a factor of f(x)
Step-by-step explanation:
We can use the Remainder Theorem to check if (x - 2) is a factor of f(x) = x^3 - 2x^2 + 2x + 3.
The Remainder Theorem states that if we evaluate a polynomial at a specific value and the result is zero, then that value must be a root of the polynomial and therefore the polynomial can be divided by the corresponding linear factor.
So, if we plug in x = 2 into f(x), we get:
f(2) = 2^3 - 2 * 2^2 + 2 * 2 + 3
= 8 - 8 + 4 + 3
= 7
Since f(2) is not equal to zero, it follows that (x - 2) is not a factor of f(x).
Alternatively, we could use the Factor Theorem, which states that a polynomial is divisible by (x - a) if and only if f(a) = 0. Since f(2) is not equal to zero, (x - 2) is not a factor of f(x).

What expression represents the value of y?
Answer:
Second choice:
[tex]\mbox{\large y = \sqrt{wz}}[/tex]
Step-by-step explanation:
Consider the right triangle ABC
By the Pythagorean theorem,
AB² = BC² + AC²
BC = x, AC = (w + x) and AB = v
Plug in above values
(w + z)² = v² + x² (1)
In right triangle BCD,
BC² = BD² + CD²
Plugging in values we get
x² = w² + y² (2)
In right triangle ABD
AB² = BD² + AD²
v² = y² + z² (3)
Plug in values of x² from eq (2) and v² from eq 3 into equation (1) to get
(w + z)² = y² + z² +w² + y²
Left side (w + z)² = w² + 2wz + z²
==> w² + 2wz + z² = y² + z² +w² + y²
w² and z² cancel out since they are on both sides of the equation with same sign
=> 2wz = y²+y²
2wz = 2y²
Divide by 2:
wz = y²
Switch sides:
y² = wz

The mean (expected value) of X is 3.48, and the standard deviation of X is 1.27.
Basketball Game Win StatsMean (Expected Value) of X:The mean or expected value of X, representing the number of games the team might win, can be calculated using the formula:
E(X) = n * p
where:
n = number of games (6)
p = probability of winning each game (0.58)
So, E(X) = 6 * 0.58 = 3.48
Standard Deviation of X:The standard deviation of X, representing the spread of the distribution, can be calculated using the formula:
SD(X) = √(n * p * (1 - p))
where:
n = number of games (6)
p = probability of winning each game (0.58)
So, SD(X) = √(6 * 0.58 * (1 - 0.58)) = 1.27

The solution of c(r) in 3D spherical coordinates behaves differently because in 3D, there are radial and angular dimensions.
What do you mean 3D coordinates?3D coordinates refers to the system of three-dimensional spatial representation of an object, where each point in 3D space is represented by a set of three values, also known as coordinates. These coordinates are typically written in the form (x, y, z), where x, y, and z represent the values along the three axes of a three-dimensional coordinate system.
3D coordinates are commonly used in computer graphics, engineering, and mathematics to describe the positions and orientations of objects in 3D space. In computer graphics, for example, objects are often represented using 3D coordinates to specify their position, orientation, and size in the virtual world. In engineering and mathematics, 3D coordinates are used to describe the positions of points in three-dimensional space and to perform transformations, such as rotations and translations, on these points.
The 3D coordinate system is a fundamental tool for visualizing, analyzing, and manipulating objects in three-dimensional space, and it provides a powerful way to describe complex 3D shapes, geometric relationships, and physical interactions.
The solution of c(r) in 3D spherical coordinates behaves differently than the solution of c(x) in 1D coordinates because in 3D, there are radial and angular dimensions to consider, which can affect the overall behavior of the solution.

Find CD.

2.) 5.3
3.) 5.5
4.) 6.3
Answer:
CD = 6.3
Step-by-step explanation:
triangles CFG and CDE are similar, so their side lengths are proportional
this means CD/CF = CE/CG
since we don't know CF, we need to first solve for CF in order to find CD
luckily, we know CD = CF + FD, and FD is given:
CD/CF = CE/CG -> (CF + FD) / (CF) = CE/CG
multiply both sides by CF to get CF + FD = CE * CF / CG
move the terms with CF to one side, and the constants to the other side:
CF - CF(CE/CG) = -FD
solve for CF:
CF(1-(CE/CG)) = -FD, CF = FD / ((CE/CG) - 1) = (1.8)/(((2.4+6)/(6)) - 1) = 4.5
Since CD = CF+FD, CD = 4.5 + 1.8 = 6.3
