If a person substitutes 2 ounces of lean meat by cooked lentils, the lentils that the person need to eat is ½ cup as both are protein.
Lean meat and lentils are among the sources of proteins in the food intake. Protein is found throughout the human body such as in muscle, skin, hair, bone, skin, hair, and every other body part or tissue. It manufactures the enzymes that power chemical reactions and the hemoglobin that carries oxygen in your blood. Protein is required by the body to help your body repair and make new cells. The foods that contain high content of proteins include lean meat, eggs, dairy products, lentils, etc. A half cup of cooked lentils provides 9 grams of protein, and 2 ounces of lean meat provides 8 grams of proteins. As the amount of protein provided by both is similar, a person can substitute one with another and maintain their protein intake.

a. To find 40% of 75, Priya calculates. Does her calculation give the correct
value for 40% of 75? Explain or show how you know.
b. If represents a number, does always represent 40% of that number?
Explain your reasoning.
40 percentage of 75 is 30 and 2/5 of 75 is 30. So, Priya calculated in a correct way.
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
That is,
2/5 of 75 is also 30
Therefore,
40 percentage of 75 is 30 and 2/5 of 75 is 30. So, Priya calculated in a correct way

Write Proportion Statement and find the missing sides of the polygon.
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.
What is probability?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.

A parabola can be drawn given a focus of ( 0 , − 2 ) and a directrix of x = − 6 . What can be said about the parabola?
The parabola has a vertex at (-3, -2), has a p-value of 3 and it opens up.
How to determine the vertex form of a parabola?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

What is the measure of an angle if the measure of its supplement is 39 more than twice the measure of its complement?.
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°.

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'
What is the change of variables formula?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 |
