The amount that the bank loaned out at 7.9% is $1,574.00
How do represent the amounts lent at different rates?
On the assumption that x amount was loaned at 7.9% and that the remaining amount, (8,200-x) was loan out at 7.4%, we can determine the interest charged on each loan as the loan multiplied by the interest rate
interest on 7.9% loan=7.9%*x=0.079x
interest on 7.4% loan=7.4%*(8200-x)
interest on 7.4% loan=606.80-0.074x
total interest=0.079x+606.80-0.074x
total interest=0.005x+606.80
total interest on loans=614.67
614.67=0.005x+606.80
614.67-606.80=0.005x
7.87=0.005x
x=7.87/0.005
x=amount loaned at 7.9%=$1,574.00

A toy car was kicked toward the target. the horizontal component of velocity was 8 m/s and the vertical component was 6m/s. calculate the magnitude of the resultant velocity of the soccer ball.
The magnitude of the resultant velocity of the soccer ball is 10 m/s .
Let the horizontal component of velocity be [tex]V_{x}[/tex] and the vertical component of velocity be [tex]V_{y}[/tex].
The magnitude of the resultant velocity will be represented by V.
So, we can write
The horizontal component of velocity = [tex]V_{x}[/tex] = 8 m/s
The vertical component of velocity = [tex]V_{y}[/tex] = 6 m/s
The relation between horizontal component, vertical component and resultant velocity is,
[tex]V^{2} = V_{x} ^{2} + V_{y} ^{2}[/tex]
On substituting value of horizontal component and vertical component, we get
[tex]V^{2}[/tex] = [tex](8)^{2} + (6)^{2}[/tex]
[tex]V^{2}[/tex] = 64 + 36
[tex]V^{2}[/tex] = 100
V = [tex]\sqrt{100}[/tex]
V = 10 m/s
The magnitude of the resultant velocity of the soccer ball is 10 m/s .

How can you use surveys, experiments and observational studies to make inferences about a population?
Surveys, Experiments, and Observational studies are some common methods of data collection in statistical studies that involve people.
A survey is a means to gather information about a group of individuals by asking some of them to respond to questions. A survey may require participants to fill out forms, respond to online questionnaires, take part in in-person interviews, or respond to questions over the phone.
In an experiment, as opposed to an observational study, different treatments are purposefully applied to several groups, and the groups are then compared to see whether there are any differences in a certain variable of interest termed a response. Researchers can determine whether various treatments have distinct effects by using a well-designed experiment.
In an observational study, a researcher utilizes data from observations to learn about a group of people. Aside from assessing their replies, the people being watched are particularly not hampered.

According to the question the equation that we have been given is
-3x + 2y = 2
We need to graph the linear equation. For this we will first put different values of x in the above equation and then find the values of y which will be the coordinates of the graph.
First put x = 0
-3(0) + 2y = 2
2y = 2
y = 1
hence the first coordinate is (0,1)
Similarly put, x = 1
-3(1) + 2y = 2
2y = 5
y = 5/2

Your friend has $100 when he goes to the fair. he spends $10 to enter the fair and $20 on food. rides at the fair cost $2 per ride. which function can be used to determine how much money he has left over after x rides? f(x) = −2x 70 f(x) = 2x 70 f(x) = −2x − 70 f(x) = −30x $100
The function which can be used to determine the amount of money he has left over after x rides is f(x)=-2x+70.
This function is linear. A linear variable function can be written in the form of y=f(x)=a+bx, where a and b are integers and x, is the variable. This function has one independent variable and one dependent variable. In the above given function y=f(x)=a+bx; y is the dependent variable and x is the independent variable.
Here since x number of rides are taken and the cost per ride is x so the total cost of x rides is given as 2x.
Since there is a total of $100 and an amount of ($10+$20=$30) is spent on entry and food respectively.
Therefore, total amount left after all the expenses can be expressed as:
f(x)=100-(30+2x)
f(x)=70-2x
f(x)=-2x+70
Therefore, function which can be used to determine the amount of money he has left over after x rides is f(x)=-2x+70.

Mariam read 4 books in 5 months. What was her rate of reading, in books per month? Give your answer as a whole number or a FRACTION in simplest form.
Answer:
¼ per month or 2 books in 2½ months
Mariam read 4 books in 5 months, resulting in a rate of reading of 4/5 books per month.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
Given that,
Mariam read 4 books
She read the books in 5 months
We need to find her rate of reading, in books per month
To find the rate of reading,
Divide the number of books read by the number of months it took to read them.
In this case, Mariam read 4 books in 5 months.
So, the rate of reading would be 4 books divided by 5 months.
Simplifying this fraction, we have 4/5,
Hence, Mariam's rate of reading is 4/5 books per month.

The distance between the two points in the simplest radical form is √61
Distance between two pointsFrom the question, we are to determine the distance between the two marked points
The marked points are (-8, 6) and (-3, 0)
The distance, d, between two points can be calculated by using the formula,
d = √((x₂ - x₁)² + (y₂ - y₁)²)
x₁ = -8
x₂ = -3
y₁ = 6
y₂ = 0
Thus,
The distance, d, between the points is
d = √((-3 - -8)² + (0 - 6)²)
d = √((-3 + 8)² + ( -6)²)
d = √((5)² + 36)
d = √(25 + 36)
d = √61

What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the segment lengths are given as follows:
|AC| = 1.|AB| = x.|BC| = 1 - x.The following proportion is true for the segment:
|AC|/|AB| = |AB|/|BC|
Hence:
1/x = x/1 - x.
x² = 1 - x
x² + x - 1 = 0.
Which is a quadratic equation with solution x = 0.618.

Given point B on segment AC, you want the "golden proportion" ratio AC/AB, such that AC/AB = AB/BC. A diagram is shown with A=0, B=x, C=1.
RedefineWe can solve for the golden proportion directly by redefining points on the line segment as ...
A = 0B = 1C = rThen we have AB = 1, AC = r, BC = r-1 and the proportion of interest is ...
AC/AB = AB/BC
r/1 = 1/(r -1)
SolutionCross-multiplying gives ...
r² -r = 1
Completing the square, we have ...
r² -r + 1/4 = 5/4
(r -1/2)² = 5/4
Taking the square root gives ...
r - 1/2 = 1/2√5
r = 1/2 + 1/2√5 = (1 +√5)/2 ≈ 1.618034
The golden ratio is (1+√5)/2 ≈ 1.618034.

465 is the cost of the cash price will she pay overall for the car.
What is cost ?
The entire cost of all fixed and variable expenses for a particular stage in the value chain is the total cost of a business function. In other words, it is the overall cost incurred during the various stages a product goes through to reach the consumer.Your cost function might resemble this, for example, if your variable costs for labor are fixed regardless of quantity while your variable costs for supplies vary depending on the amount of each item. Total costs are calculated as fixed costs plus labor costs plus (unit count * material variable costs).25 % of cash price 4500 × 25% = 1125
12 monthly 320 × 12 = 3840

Review on r. gao and a. j. kleywegt. distributionally robust stochastic optimization with wasserstein distance -
A paradigm for decision-making under certainty called distributionally resistant stochastic optimization (DRSO) seeks solutions that function well for a specified set of probability distributions. There have been many different methods offered for describing a set of distributions. The decision is significant since it has an impact on the outcomes, and the relative effectiveness of various options depends on the traits of the issues. In this study, we take into account issues where various random variables show some degree of reliance, but the precise values of the parameters describing the dependence are unknown.We also get the DRSO problem in a dual reformulation. The formulation also has the advantage of avoiding a problem related to the one-sided moment constraints in moment-based DRSO issues, which is a desirable result.Learn more about DRSO
