Debt payments relate to gross income in terms of the debt-to-income (DTI) ratio by total debt payments are divided by total. gross income.
How do debt payments relate to gross income?
The debt-to-income (DTI) ratio is a financial measurement used by lenders to assess a borrower's ability to manage debt payments. It is calculated by dividing the borrower's total debt payments by their total gross income. The resulting ratio is expressed as a percentage and indicates the portion of the borrower's income that goes towards paying their debt obligations.
For example, if a borrower has total debt payments of $1,000 per month and a gross income of $4,000 per month, their DTI ratio would be 25% ($1,000 divided by $4,000). A lower DTI ratio indicates that a borrower has more disposable income available after paying their debts and is generally viewed as a positive factor by lenders when considering a borrower for a loan or credit.
So, correct option is total debt payments are divided by total gross income.

When playing baseball, Chad misses on 60% of the pitches he receives. Describe
how to use random digits to simulate the probability that he will get a hit on more
than 2 of every 10 pitches he receives.
This proportion represents the estimated probability that Chad will get a hit on more than 2 of every 10 pitches he receives.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
To simulate the probability that Chad will get a hit on more than 2 of every 10 pitches he receives using random digits, follow these steps:
1. Divide the pitches into groups of 10. For each group of 10 pitches, record the number of hits that Chad gets.
2. Generate a random digit between 0 and 9 for each pitch in the group. If the digit is 0, 1, 2, or 3, consider it a hit. If the digit is 4, 5, 6, 7, 8, or 9, consider it a miss. Repeat this process for each group of 10 pitches.
3. Count the number of groups of 10 pitches in which Chad gets more than 2 hits.
4. Repeat steps 2 and 3 a large number of times (for example, 1000 times) to get an estimate of the probability that Chad will get a hit on more than 2 of every 10 pitches he receives.
5. Calculate the proportion of times in which Chad gets more than 2 hits in a group of 10 pitches.
Therefore, this proportion represents the estimated probability that Chad will get a hit on more than 2 of every 10 pitches he receives.

Answer:
Step-by-step explanation:
The triangles are similar so the ratio of their corresponding sides will be the same. That is, TV/RV is equal to TS/RQ. This gives us the equation 12/x+6=16/x+1. Cross multiplying, this becomes 12x+12=16x+96. Simplifying, we get x=21. Therefore, RV=12+x-6=x+6=21+6=27.
Answer:
TV/RV=TS/RQ, 12/x+6=16/x+1, 12x+12=16x+96, x=21. Therefore, RV=12+x-6=x+6=21+6=27.

The measure of angle T in the given quadrilateral is 92.5 degrees.
What is quadrilateral inscribed in circle?A quadrilateral is said to be inscribed in a circle if all four of its vertices are located on the circumference of the circle. In other terms, the quadrilateral is "enclosed" by the circle. The opposing angles of a quadrilateral are supplementary (add up to 180 degrees) and the product of the measurements of the two diagonals equals the sum of the products of the measures of the pairs of opposite sides when a quadrilateral is inscribed in a circle, both of which are important features. Inscribed quadrilateral geometry difficulties can be resolved by using these characteristics.
The sum of the angles in a quadrilateral is 360 degrees.
angle R + angle S + angle T + angle U = 360 degrees
79 degrees + 96 degrees + x + angle U = 360 degrees
Angle T and angle U are opposite angles in quadrilateral RSTU, therefore congruent.
175 degrees + 2x = 360 degrees
2x = 185 degrees
x = 92.5 degrees
Hence, the measure of angle T is 92.5 degrees.

a company receives an average of .64 purchase orders per minute. assuming a poisson distribution for the number of purchase orders per minute, what is the standard deviation for this distribution?
The standard deviation for the given Poisson distribution is 0.8.
A Poisson distribution is used to model the number of events occurring in a fixed time interval when the events occur independently and at a constant rate. The mean and variance of a Poisson distribution are equal, and both are given by λ, the rate parameter.
Here, the given information is that the company receives an average of 0.64 purchase orders per minute. Therefore, λ = 0.64.
The formula for the variance of a Poisson distribution is σ² = λ, where σ is the standard deviation. Thus, substituting λ = 0.64 in this formula, we get σ² = 0.64. Taking the square root of both sides, we get σ = √0.64 = 0.8.
Therefore, the correct answer is 0.8.

the circular movement of an object in the coordinate plane
Answer:
rotation to the right in the coordinate plane
The BEST definition for clockwise rotation on the coordinate plane is "rotation to the right in the coordinate plane." option B is correct.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
"Rotation to the right in the coordinate plane" is the BEST definition for clockwise rotation on the coordinate plane. In the coordinate plane, a rotation that turns a point or object to the right of the origin is referred to as being clockwise.
It follows that if a straight line were to stretch from the origin to the point or item, it would spin as it traveled in a clockwise direction. In comparison, a rotation in the other direction would cause the line to spin to the left.
Although notation can be used to depict the magnitude and direction of rotation in the coordinate plane, this does not always mean that the rotation is clockwise.
Therefore, Rotation to the right in the coordinate plane is the BEST definition for clockwise rotation on the coordinate plane.

Angle x and y are complementary. Angle x is supplementary to a 128° angle. What are the measures of angle x and angle y.
Answer:
Step-by-step explanation:
Short answer? x is 52 degrees and y is 38 degrees.
But how did I get it you probably did not ask?
Let's run it back to the definitions of complementary and supplementary angles.
Complementary angles: 2 angles that add to get you a CLEAN 90 degrees
Supplementary angles: 2 angles that add to get you a CLEAN 180 degrees
So if x is supplementary to 128 degrees, it has to be 52 degrees to fit the definition. So yeah 180-128= 52 degrees
Now for x to be complementary to y, y has to 38 degrees. 90-52=38 degrees.

Derive the formula for the Pythagorean theorem in 3 dimensions. Math help ASAP
The formula for the Pythagorean theorem in 3 dimensions is [tex]d^2 = a^2 + b^2 + c^2.[/tex]
What is Pythagorean theorem?
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be extended to 3 dimensions using the same principle.
In the case of a cube with base a, width b, and height c, we can imagine a right triangle that is formed by one of the diagonals of the cube and one of the faces. Let d be the length of this diagonal.
By the Pythagorean theorem in 3 dimensions, we have:
[tex]d^2 = a^2 + b^2 + c^2[/tex]
To see why this is the case, imagine that we have a right triangle in three dimensions, with sides of length a, b, and c.
The hypotenuse of this triangle is the diagonal of a rectangular box with sides of length a, b, and c. By the Pythagorean theorem, the square of the length of the diagonal is equal to the sum of the squares of the lengths of the other two sides, which gives us the formula above.
Therefore, the formula for the Pythagorean theorem in 3 dimensions is [tex]d^2 = a^2 + b^2 + c^2.[/tex]

b) the maximum height of the rocket is 1378 feet at t=7sec.

d)14.13 seconds will take it to hit the ground
Define quadratic formulaThe quadratic formula is a formula that gives the solutions (or roots) of a quadratic equation of the form ax^2 + bx + c = 0, where a, b, and c are coefficients, and x is the variable:
x = (-b ± √(b² - 4ac)) / (2a)
a) The function that describes the height of the rocket in terms of time t can be expressed as:
h(t) = -16t² + 224t + 98
where h(t) represents the height of the rocket (in feet) at time t (in seconds).
The -16t² term represents the effect of gravity, which causes the rocket's height to decrease over time. The 224t term represents the initial velocity of the rocket, which causes its height to increase over time. The constant term 98 represents the initial height of the rocket (at t = 0).
b) To determine the time at which the rocket reaches its maximum height, we need to find the vertex of the parabolic function h(t). The x-coordinate of the vertex is given by:
t = -b / (2a)
where a = -16 (the coefficient of t²) and b = 224 (the coefficient of t). Substituting these values, we get:
t = -224 / (2×(-16)) = 7
Therefore, the rocket reaches its maximum height at t = 7 seconds.
To find the maximum height, we can substitute t = 7 into the function h(t) and simplify:
h(7) = -16(7)²+ 224(7) + 98 = 1378
Therefore, the maximum height of the rocket is 1378 feet.
c) To find the time interval during which the rocket is more than 702 feet above ground level, we need to solve the inequality:
h(t) > 702
Substituting the expression for h(t), we get:
-16t² + 224t + 98 > 702
Simplifying and rearranging terms, we get:
16t² - 224t - 604 < 0
Using the quadratic formula, we can solve for the roots of the equation:
t = [224 ± √(224²- 4(16)(-604))] / (2(16))
t ≈ 1.95 or t ≈ 18.55
Therefore, the rocket will be more than 702 feet above ground level during the time interval [1.95, 18.55].
d) To find the time at which the rocket hits the ground, we need to find the root(s) of the function h(t) where h(t) = 0. This occurs when the rocket returns to ground level (i.e., h(t) = 0) after reaching its maximum height.
Substituting the expression for h(t), we get:
-16t²+ 224t + 98 = 0
Using the quadratic formula, we can solve for the roots of the equation:
t = [224 ± √(224² - 4(-16)(98))] / (2(-16))
t ≈ 14.13 or t ≈ -0.38
the rocket hits the ground after approximately 14.13 seconds.
