is y=1/3x+5 proportional or non proportional

Therefore, the transformation of the double integral can be expressed as follows: ∫∫g(x', y') (x' + 1)(y' - 1) dx' dy' = ∫∫g(x', y') (x' + 1)(y' - 1) |J| dA'

the alteration of variables A mathematical trick known as a formula is used to switch the variables in an integral from one set of variables to another. The integral is frequently simplified or made easier to solve by doing this. Given a function f(x) and two sets of variables x and y, the integral of f(x) with respect to x may be represented as the integral of a transformed function g(y) with respect to y, where g(y) is connected to f(x) by a functional connection between x and y. For instance, the integral of f(x) with respect to x can be expressed as the integral of f(sqrt(y)) with respect to y if x and y are connected by the equation y = x2.

How to solve?

x' = x - 1

y' = y + 1

∫∫g(x, y) xy dA = ∫∫g(x', y') (x' + 1)(y' - 1) dx' dy'

∫∫f(x, y) dA = ∫∫f(x', y') |J| dA'

|J| = | ∂x'/∂x ∂x'/∂y |

| ∂y'/∂x ∂y'/∂y |

|J| = | 1 0 |

| 1 1 |

Therefore, the transformed double integral can be expressed as follows:

∫∫g(x', y') (x' + 1)(y' - 1) dx' dy' = ∫∫g(x', y') (x' + 1)(y' - 1) |J| dA'

The measure of the angle is 39°.

Complementary angles are angles whose sum is equivalent to 90°. On the other hand, supplementary angles are angles whose sum is equivalent to 180°.

Let x be the measure of the angle.

90° - x = complement angle of x

180° - x = supplement angle of x

If the measure of its supplement is 39 more than twice the measure of its complement, then

180° - x = 39 + 2(90° - x)

Simplify and solve for x.

180° - x = 39 + 2(90° - x)

180° - x = 39 + 180° - 2x

x = 39°

Hence, the measure of the angle is 39°.

The parabola has a vertex at (-3, -2), has a p-value of 3 and it opens up.

Mathematically, the vertex form of a parabola is represented by this mathematical expression:

y = a(x - h)² + k

Where:

h and k represents the vertex of the equation.

In Mathematics, the focus for either a right or left parabola is modeled by this mathematical expression (h + p, k) while its directrix is modeled by this mathematical expression x = h - p;

h + p = 0   ⇒ h = -p

h - p = -6

Solving the set of linear equations simultaneously, we have:

-p - p = -6

-2p = -6

p = 6/2

p = 3

For the value of h, we have:

h = -3.

Additionally, the vertex form of this parabola is given by:

y = a(x - h)² + k

The lengths of the sides AN, PM, and MO of the given polygons are 26, 40, and 96, respectively.

We are given two triangles. The vertices of the first triangle are A, N, and T. The vertices of the second triangle are P, O, and M. Both the triangles are right-angled. The triangles are similar to each other. The lengths of the sides AT and TN are 10 and 24, respectively. We will use the Pythagorean theorem to find the length of side AN.

AN = √[(10)² + (24)²] = √(100 + 576] = √676 = 26

Now, as we know the triangles are similar, the lengths of the corresponding sides must be in the same proportion. The ratio is calculated as given below.

r = PO/AN = 104/26 = 4

The length of the side PM is equal to r*AT = 4*10 = 40. The length of the side MO is equal to r*TN = 4*24 = 96.

0.0668 is the probability that 16 randomly selected packages will have a sample mean weight in excess of 16.075 ounces.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. For instance, the theoretical chance of getting a head when tossing a coin is 12. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Given,

To find 40% of 75, Priya calculates 2/5 of 75

We have to find the value of 40% of 75.

Percentage;

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The sign "%" is used to denote it.

Now,

Lets find;

40% of 75

40/100 × 75 = 40/4 × 3 = 10 × 3 = 30

That is,

40% of 75 is 30.

Now,

2/5 of 75

2/5 × 75 = 2 × 15 = 30

Amina has a bag of 6 black balls and 4 green balls. Hamad has a bag of 3 black balls and 5 green balls. If one ball is drawn from each bag, the probability that one is black and one is green is 0.525.
