the Pearson product moment correlation measures the linear relationship between two interval- and/or ratio-scaled variables (scale variables) such as those depicted conceptually by scatter diagrams: True.
What is Pearson product moment correlation?A measure of the degree and direction of relationship between two variables assessed on at least an interval scale is the Pearson product-moment correlation coefficient, or Pearson's correlation.
If you want to determine whether there is a linear relationship between two quantitative variables, you may use Pearson's correlation. The expectation of a linear relationship between those variables is the sole part of the study hypothesis.
This approach finds the precise amount or degree of correlation between any two variables and tells if there is or is not any correlation between them.
Thus, the given statement is true.

A metal block has a mass of 5kg, correct to the nearest 50 grams. find the upper bound
Therefore, the solution to given problem is the density of metal block comes out to be 2717.4 kg/[tex]m^{3}[/tex]
What is density?The substance's density is defined as its mass per unit of volume. Although the Latin letter D can also be utilized, the most popular density symbol is. In mathematics, density is calculated as mass divided by volume:
Here,
Given : mass =5kg
volume = 1.84 x [tex]10^{-3}[/tex]
thus, density = mass/volume
we apply density formula , we get
density = 5/ 1.84 x [tex]10^{-3}[/tex]
density =2717.4 kg/[tex]m^{3}[/tex]
Therefore the density of metal block comes out to be 2717.4 kg/[tex]m^{3}[/tex]

Use the factor theorem to determine whether v + 5 is a factor of v 4 + 16v 3 + 8v 2 - 725. No yes.
By factor theorem (v+5) is not a factor of the given polynomial f(v).
What does factor theorem mean?
When thoroughly factoring the polynomials, mathematicians apply the factor theorem. The polynomial's zeros and factors are connected by this theorem.
The factor theorem states that if a is any real number and f(x) is a polynomial of degree n 1 then (x-a) is a factor of f(x) if f(a)=0.
The factor theorem states that
f(x) has a factor (x-k) if and only if f(k) = 0
We are given the following information.
F(v) = v 4 + 16v 3 + 8v 2 - 725
We have to check whether (v+5) is a factor of given polynomial.
( v + 5 ) = ( v - ( - 5 )
f( -5 ) = [tex]( -5 )^{4} + 16( -5)^{3} + 8( -5)^{2} - 725[/tex]

If 250 kilograms of corn are needed to feed 5,000 chickens, how many
chickens can be fed with 140 kilograms of corn?
The number of chickens that can be fed with 140 kg of corn is 2800.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 8 is an equation.
We have,
250 kg corn = 5000 chicken
Multiply 140/250 on both sides.
140 kg of corn = 140/250 x 5000 chicken
140 kg of corn = 2800 chicken
Thus,
2800 chickens can be fed with 140 kg of corn.

2 cos x - sin x=3/(2 cos x+sin x)
The solution of the trigonometric equation is x = 26.57° or 153.43°
What is a trigonometric equation?A trigonometric equation is an equation that contains the trigonometric ratios.
How to solve for x in the trigonometric equation?Given the trigonometric equation 2cos x - sin x = 3/(2cos x + sin x)
We solve for x in the equation. We proceed as follows.
Since 2cos x - sin x = 3/(2cos x + sin x)
Multiplying both sides by (2cos x + sin x), we have that
(2cos x - sin x)(2cos x + sin x) = 3
Now, we know that (a² - b² = (a + b)(a - b)
Applying this where a = 2cosx and b = sinx, we have that
(2cos x - sin x)(2cos x + sin x) = 3
(2cos x)² - (sin x)² = 3
4cos² x - sin² x = 3
Since sin²x = 1 - cos²x, substituting this into the equation, we have that
4cos² x - sin² x = 3
4cos² x - (1 - cos²x) = 3
4cos² x - 1 + cos²x = 3
4cos² x + cos²x = 3 + 1
5cos²x = 4
cos²x = 4/5
Taking square root of both sides, we have that
cosx = ±√(4/5)
cosx = ±2/√5)
cosx = ±2/√5 × √5/√5
cosx = ±2√5/5
Taking inverse cosine of both sides, we have
x = cos⁻¹(±2√5/5)
x = cos⁻¹(±0.8944)
x = cos⁻¹(0.8944) or x = cos⁻¹(-0.8944)
x = 26.57° or (180 - 26.57)°
x = 26.57° or 153.43°
So, the solution is x = 26.57° or 153.43°

We infer that x and y's relationship is a non-linear function as a result. The relationship between x and y is a non-linear function.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Four main categories can be used to classify different sorts of functions.

Because each input value has one and only one output value, the data in the table unmistakably indicate a function. In other words, the x values are not repeated.
Additionally, it is evident from the table numbers and the graph that the function is not linear because the graph is not a straight line. Additionally, the largest power over the x variable(s) in a cubic function is 3. It is not a linear function, therefore.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

alis teacher plotted the numbers 1/2 and 2/3 on the number line. She asked ali to find and plot a rational number between these two numbers in a number line, Can you help Ali in plotting a rational number between them on a number line?
Yes, there are many rational numbers that can be plotted between 1/2 and 2/3 on the number line. Here are a few examples:
1/2 + 1/6 = 5/6: This rational number is greater than 1/2 and less than 2/3.
2/5: This rational number is also greater than 1/2 and less than 2/3.
1/3: This rational number is halfway between 1/2 and 2/3.
To plot a rational number on a number line, you can start by drawing the number line and marking off the positions of 1/2 and 2/3. Then, you can locate the position of the rational number you are trying to plot by dividing the distance between 1/2 and 2/3 into equal segments and finding the position of the rational number within those segments. For example, if you wanted to plot 5/6, you could divide the distance between 1/2 and 2/3 into six equal segments, and then mark the fifth segment as the position of 5/6 on the number line.

You have one penny, one nickel, one dime, and one quarter. How many different amounts of money can you make using
one or more of these coins?
Answer:
15
Step-by-step explanation:
To find the total number of combinations you can make with these four coins, we have to do 2 to the power of the total amount of coins. This because each coin has two choices: to be included in the combination or not. There are 4 total coins, and 2^4 is 16. There are 16 total combinations. But since one of those possibilities are that none of the coins are included, we subtract 1 from the total, and get 15. There are 15 combinations with 1 or more coins, which each give us different amounts.
