The value of x will be 0 and x = 5. The correct option is A.

The x-intercept is the point at which a line intersects the x-axis, and the y-intercept is the point at which the line intersects the y-axis.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the x-intercept(s) of the function is the quantity of 5x² - 25x.

The value of the x-intercept will be calculated as,

5x² - 25x = 0

5x( x -25) = 0

5x = 0 and x - 5 = 0

x = 0  and x = 5

Therefore, the value of x will be 0 and x = 5. The correct option is A.

Answer:

A. unbiased estimator.

Step-by-step explanation:

In Statistics, an estimator is a statistical value which is used to estimate a parameter. Parameters are the determinants of the probability distribution. Therefore, to determine a normal distribution we would use the parameters, mean and variance of the population.

A function of random variables used to estimate a parameter of a distribution is an unbiased estimator.

An unbiased estimator is one in which the difference between the estimator and the population parameter grows smaller as the sample size grows larger. This simply means that, an unbiased estimator captures the true population value of the parameter on average, this is because the mean of its sampling distribution is the truth.

Also, we know that the bias of an estimator (b) that estimates a parameter (p) is given by; \(E(b) - p\)

Hence, an unbiased estimator is an estimator that has an expected value that is equal to the parameter i.e the value of its bias is equal to zero (0).

Generally, in statistical analysis, sample mean is an unbiased estimator of the population mean while the sample variance is an unbiased estimator of the population variance.

The completely factored form of the polynomial is 7x² (x + 6) (x - 4)

Given,

The polynomial ; 7x⁴ + 14x³ - 168x²

We have to find the complete factored form of this polynomial;

Polynomial;

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable).

Here,

The polynomial is  7x⁴ + 14x³ - 168x²

Now,

Factorize the polynomial using common factors;

That is,

7x⁴ + 14x³ - 168x²

7x² (x² + 2x - 24)

Solve x² + 2x - 24 using quadratic formula;

That is,

\(\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}\) = \(\frac{-2(+-)\sqrt{2^{2} -4*1*-24} }{2*1}\) = \(\frac{-2(+-)\sqrt{4-96} }{2}\) = -2±√-92 / 2

Now,

Solve

-2 + √-92 / 2 = 3.79 ≈ 4

Solve

-2 - √-92 / 2 = -5.79 ≈ -6

Then,

The factors will be (x - 4) and (x + 6)

So,

7x² (x + 6) (x - 4) will be the factored form of the polynomial.

x = 2 is the solution to the equation 5x - 2 = 8.

What is the logarithm?

A logarithm is a power to which a number must be raised in order to get some other number. For example, the base ten logarithms of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.

The change of base formula for logarithms allows us to change the base of a logarithm without changing the value of the logarithm.

The formula is: logb(x) = (logc(x)) / (logc(b))

To solve 5x - 2 = 8 using the change of base formula, we will first bring the equation to one side and get 2 = 5x - 8.

Then we will add 8 to both sides of the equation to get 2 + 8 = 5x, which gives us 10 = 5x.

Finally, we will divide both sides of the equation by 5 to get x = 2.

x = 2

Therefore, x = 2 is the solution to the equation 5x - 2 = 8.

The value of m in the proportion is given as follows m = 3.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The proportion is defined as follows:

3/4 = (1/4)m.

As the values have a proportional relationship, the value of m can be obtained applying cross multiplication, as follows:

3/4 = (1/4)m

cross multiplication;

3/4 x 4 = m

m = 3

Hence m =3 is the value that satisfies the proportion in this problem.

1) AD = 9 in

2) DE = 9.25 in

3) ∠EDC = 36°

4) ∠AEB = 108°

5) 11.5 in

Step-by-step explanation:

1) AD = BC = 9in

2) AC = BD (diagonals are equal)

⇒ BD = 14.25

⇒ BE + DE = 14.25

⇒ 5 + DE = 14.25

DE = 9.25

3) Since AB ║CD,

∠ABE = ∠EDC = 36°

4) ∠ABE = ∠BAE = 36°

Also ∠ABE + ∠BAE + ∠AEB = 180 (traingle ABE)

⇒ 36 + 36 + ∠AEB = 180

∠AEB = 108

5) midsegment = (AB + CD)/2

There is no point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1).

To find the point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1), we can use the concept of orthogonal projection.

First, let's denote the point on the plane as (x, y, z). The vector from this point to (2, 0, 1) can be represented as the vector (2 - x, 0 - y, 1 - z).

Since the point on the plane is on the plane itself, it must satisfy the equation 4x + 5y + z = 12. We can use this equation to find a relationship between x, y, and z.

Substituting the values of x, y, and z into the equation, we have:

4x + 5y + z = 12

4(2 - x) + 5(0 - y) + (1 - z) = 12

Simplifying, we get:

8 - 4x - 5y + 1 - z = 12

9 - 4x - 5y - z = 12

-4x - 5y - z = 3

Now, we have a system of two equations:

4x + 5y + z = 12

-4x - 5y - z = 3

To find the point on the plane nearest to (2, 0, 1), we need to solve this system of equations.

Adding the two equations together, we eliminate the variable z:

(4x + 5y + z) + (-4x - 5y - z) = 12 + 3

Simplifying, we get:

0 = 15

Since 0 = 15 is not true, the system of equations is inconsistent, which means there is no solution.

This implies that there is no point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1).

To compare Bob and Alan's points per game, we can use the following summary statistics:

Mean: This is the average of the data set. It can be calculated by adding up all the values and dividing by the number of values.

Median: This is the middle value of the data set when it is arranged in order.

Range: This is the difference between the largest and smallest value in the data set.

Interquartile range (IQR): This is the range of the middle 50% of the data set, calculated as the difference between the 75th and 25th percentiles.

Mean absolute deviation (MAD): This is the average of the absolute differences between each value and the mean.

To compare the center of each player's data, the best measure of central tendency would be the mean. This is because it takes into account all the values in the data set and gives an overall average. The median can also be used, but it only considers the middle value and may not accurately represent the center if there are outliers in the data set.

To compare the spread of each player's data, the best measure of spread would be the range or IQR. This is because they give an idea of the range of values in the data set and how spread out the data is. The MAD can also be used, but it is a more complex calculation and may not provide as clear of an understanding of the spread of the data.

Based on the representations, summary statistics, and interpretations, it is not possible to determine if either friend is a basketball star without more context. A basketball star could have a high average points per game, a narrow range, and a small spread, but this would depend on the level of competition and the type of game being played. A player who consistently scores a high number of points and performs well under pressure could be considered a basketball star, but this cannot be determined solely based on the data presented.

The equation for a circle centered at the origin is x² + y² = r².

The equation for a circle centered at the origin is given by:

x² + y² = r²

In this equation, (x, y) represents a point on the circle, and r represents the radius of the circle.

Let's break down the equation step by step:

The center of the circle is at the origin, which means the coordinates of the center are (0, 0).

To find the equation of a circle, we start with the general equation for a circle: (x - h)² + (y - k)² = r², where (h, k) represents the coordinates of the center and r represents the radius.

Since the center is at the origin (0, 0), the equation simplifies to x² + y² = r².

The term x² + y² represents the sum of the squares of the x-coordinate and the y-coordinate of any point on the circle.

Therefore, the equation for a circle centered at the origin is x² + y² = r².
