By using the concept of reflection, it can be calculated that-

Value of x is 6 and value of y is -7

What is reflection?

Reflection is a mathematical transformation in which a mirror image of an object can be formed with respect to a line called the line of reflection.

The point is (-2, -4)

(-2, 4) is reflected across y-axis

New coordinate after reflection = (2, -4)

By the problem,

(x - 4, y + 3) = (2, -4)

x - 4 = 2

x = 2 + 4

x = 6

y + 3 = -4

y = -4 - 3

y = -7

The ratio of false positives to true positives is 3/49.

So, option B is correct.

A percentage is an expression that converts two ratios into an equal value. For instance, you may write the ratio as 1: 3 if there is 1 man and 3 women, meaning that 40% of the population is female and 14% is male. For any two numbers, the ratio formula is stated as a: b a/b. The percentage formula, on the other hand, is represented as a:b::c:da:b::c:da:b=cd. In mathematics, a ratio shows how many times one number is represented by another. For instance, if there are eight oranges and six lemons in a dish of fruit, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

The percentage of false positives=3%

The percentage of true positives=49%

Ratio=3/49

Therefore, the ratio of false positives to true positives is 3/49.

So, option B is correct.

The area of the image is, 7396 square pixels.

what is area?

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

Let x represent the length and the width of the image.

The area of the image and the border is represented by the expression

(x + 4)^2.  

Total area - area of image = Area of border

(x + 4)^2   -          x^2          =     704

⇒ x^2 + 8x + 16 - x^2 - 704 = 0

                             8x - 688 = 0

                                       8x = 688

                                         x = 86

The image will be 86 pixels by 86 pixels.

The area becomes  86*86 = 7396 square pixels.

Hence, the area of the image is, 7396 square pixels.

For [tex]f(x)=3x-\frac{1}{2}[/tex], comparing it with slope-intercept form yields that the slope is [tex]3[/tex] and the [tex]y[/tex]-intercept is [tex]-1/2[/tex].

For the graphed function, the slope is [tex]\frac{-4-0}{-2-6}=\frac{1}{2}[/tex] and the [tex]y[/tex]-intercept is about [tex]-3[/tex].

For the 5.5% coupon corporate bond, the coupon payment would be $55 per year. For the 6.45% coupon treasury note, the coupon payment would be $64.50 per year.

Calculations using percentages show how much a given number contributes to the total. It is computed by dividing the number by the sum and multiplying by 100. It is denoted by the sign "%." For example, if a basket contains ten apples, three of which are red, the proportion of red apples in the basket is 30% (3/10 x 100). In a wide range of disciplines, including business, statistics, and education, percentage is often utilized. Calculating interest rates, taxes, and other financial activities in the finance industry annually frequently uses percentages. The frequency of events or the likelihood of a certain outcome are both measured using this method in statistics. Calculating grades and evaluating a student's overall performance are both done using this in education.

How to solve?

For the 5.5% coupon corporate bond, the coupon payment would be 5.5% of $1,000 = $55 per year.

For the 6.45% coupon treasury note, the coupon payment would be 6.45% of $1,000 = $64.50 per year.

For the corporate zero-coupon bond maturing in 10 years, there are no coupon payments. The bond will only make a payment of $1,000 at maturity.

Check the picture below.

The following expression represents a 2-scale factor vertical stretch, a transformation of 4 units left, and a transformation of 1 unit down:

g(x) = 2f(x + 4) - 1

A vertical stretch of scale factor K is expressed as follows for the general function f(x):

g(x) = Kf(x).

Horizontal translation:

A horizontal translation of N units for a general function f(x) is written as:

g(x) = f(x + N).

The shift is to the left if N is positive and the shift is to the right if N is negative.

Vertical translation:

A vertical translation of N units for a generic function f(x) is expressed as follows:

g(x) = f(x) + N.

When N is positive, there is an upward movement and N shifts downward if it is negative.

So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:

g(x) = 2f(x)

Then we translate it into 4 units left:

g(x) = 2f(x + 4)

Then we translate 1 unit down:

g(x) = 2f(x + 4) - 1

This is the equation for the transformation.

Answer: A linear equation in the form y = mx + b can be determined by examining the values in the table. To find the value of m, we can use the formula for the slope of a line, which is (y2 - y1) / (x2 - x1). Using the first and last values in the table, we can compute the slope as (7 - 15) / (4 - 0) = -1/4.

Therefore, the equation that represents the table is:

y = (-1/4) * x + b

We can use any of the given points to find the value of b. For example, using the point (1, 13), we can solve the equation to find b:

13 = (-1/4) * 1 + b

b = 14 - 1/4 = 13 3/4

Therefore, the final equation that represents the table is:

y = (-1/4) * x + 13 3/4

Answer:

40° and 110°

Step-by-step explanation:

the sum of the 4 angles in a quadrilateral = 360°

the ratio of 2 angles = 4 : 11 = 4x : 11x ( x is a multiplier )

sum the 4 angles, equate to 360 and solve for x

140 + 70 + 4x + 11x = 360

210 + 15x = 360 ( subtract 210 from both sides )

15x = 150 ( divide both sides by 15 )

x = 10

Then

4x = 4 × 10 = 40°

11x = 11 × 10 = 110°

the measure of the 2 angles is 40° and 110°

On solving the question, by help of Highest common Factor we got that He can only produce 4 bags before there are no more cookies left.

Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.

Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

According to our question-

A shampoo's unit price is its cost per ounce. It is a straightforward division problem that may be solved with a simple calculator or pen and paper.

The first size weighs 14.2 ounces and costs $3.98.

This shampoo's unit price is ($3.98/14.2 oz) = $0.28/oz ( rounded off to nearest cent)

The second size weighs 33.9 ounces and costs $9.98.

The second shampoo's unit price is ($9.98/33.9 oz) = $0.29/oz (also rounded off to nearest cent)

Step-by-step explanation:

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The form of the container the water is contained in affects how much water is contained inside. You must know the length, breadth, and depth of a square or rectangular vessel in order to calculate its volume using the volume equation V=L*W*D, where L stands for length, W for width, and D for depth. The volume equation in this case reads: V= (r²)Dπ, where r stands for the radius, D for depth, and, or pi, is a constant value that is typically rounded to 3.14. To perform the same volume calculation for a circular vessel, you must know the vessel's depth and diameter or radius.

Given, the water park has water which is 8.6*10⁵ gallons.

We know that 10⁵ = 100000

Thus, 8.6*10⁵ = 860000

The new ride would use an additional 9.1*10⁴ gallons.

Again, 10⁴ = 10000

Thus, 9.1*10⁴ = 91000

Total water that would be required now is equal to the sum of the original water volume and the volume required by the new ride

= (860000+91000) gallons

= 951000 gallons

= 9.51*10⁵ gallons

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The area of a shape is the "space encased inside the border or the limit" of the given shape. We compute the region for various shapes utilizing math equations.

Perimeter = 520 feet, area = 12000 feet

We know that,

Perimeter = 2(L + B)

2(L + B) = 520

(L + B) = 260--------(1)

And

Area = L×B = 12000

From equation(1),we get

L(L - 260) = 12000

L^2 - 260L = 12000

L^2 - 260L - 12000 = 0
