What is the mean and median of the data 4,8,11,6,4,5,9,10,10,4

Answer:

24

Step-by-step explanation:

We can simplify this equality by squaring both sides.

[tex](\sqrt{x})^2 < 5^2[/tex]

[tex]x < 25[/tex]

We know that the greatest integer less than 25 is 24. Therefore, this is the greatest integer solution to the inequality.

The population will exceed 7569 at moments beyond 7.4 years hence from 8 years (to the nearest years)​

Exponential function is a function of the form f(x) = a e^(kt)

Considering the given problem,

the initial value = a

the base factor = k

the exponents in time = t

Information given in the problem are

solving for the time wen the population will exceed 7569

7569 = 1600 x e(0.21 * t)

7569 / 1600 = e(0.21 * t)

take ㏑ of both sides

㏑ (7569 / 1600) = ㏑ e(0.21 * t)

㏑ (7569 / 1600) = 0.21t

t = ㏑ (7569 / 1600) / 0.21

t = 7.40

The normal to the parabola[tex]z = x^2 + y^2[/tex] at the point (3, 3, 18) intersects the parabola again at the point (-1/3, -1/3, 20).

To find the normal to the paraboloid[tex]z = x^2 + y^2[/tex] at points (3, 3, 18), we first need to find the slope of the surface at that point. The gradient vector is given by

[tex]∇f(x,y,z) = < 2x, 2y, -1 >[/tex]

So the gradient vector at points (3, 3, 18) is

∇f(3, 3, 18) = <6, 6, -1>

This gradient vector is orthogonal to the plane tangent to the surface at the point (3, 3, 18). So the surface normal at this point is parallel to the gradient vector and can be expressed as

x = 3 + 6t

y = 3 + 6t

z = 18 - t

To discover where this line converges the parabola once more, we ought to substitute the x, y, and z equations into the parabola's condition. 

[tex]z = x^2 + y^2[/tex]

So it looks like this:

[tex]18 - t = (3 + 6t)^2 + (3 + 6t)^2[/tex]

[tex]18 - t = 18t^2 + 36t + 18[/tex]

[tex]0 = 18t^2 + 37t[/tex]

t=0 or t=-37/18

The value t = 0 corresponds to the starting point (3, 3, 18), so we are interested in the second value t = -37/18. Substituting this value into the normal equation gives:

x = 3 + 6(-37/18) = -1/3

y = 3 + 6(-37/18) = -1/3

z=18-(-37/18)=360/18=20

therefore, the normal to the parabola [tex]z = x^2 + y^2[/tex] at the point (3, 3, 18) intersects the parabola again at the point (-1/3, -1/3, 20).

Let us assume a linear regression model where the number of defects per countertop is projected based on the number of hours of training an employee has received. The 99% prediction interval for the number of defects per countertop can be evaluated applying the formula
y' ± t(α/2,n-2) × s[y"]
here
y' = predicted value of y,
t(α/2,n-2) = t-critical value for a given level of confidence (in this case 99%)

A. Commutative Property of Multiplication

Answer:

Yes, 86.76 is a rational number. A rational number is any number that can be expressed as a ratio of two integers (where the denominator is not zero).

86.76 can be expressed as the ratio of two integers: 8676/100, which can be simplified to 2169/25. Since 2169 and 25 are both integers, and the denominator is not zero, 86.76 is a rational number.

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

A rational number is any number that can be expressed as the ratio of two integers (i.e., a fraction where the numerator and denominator are both integers).

In this case, we can express 86.76 repeating as the fraction:

8676/100 = 8676 ÷ 100

Simplifying this fraction, we get:

8676/100 = 8676 ÷ 4 ÷ 25 = 2169/25

Since 2169 and 25 are both integers, we have expressed 86.76 repeating as a ratio of two integers, and therefore it is a rational number.

The ability of an event to occur is known as probability. The occurrence of random events is the subject of this branch of mathematics. The value is expressed as a number between 0 and 1. Probability has been introduced in mathematics to predict how likely events are to occur.

Here in the question,

2 coins are flipped at the same time.

The possible outcomes are as follows:

H H

H T

T H

T T

So, there are 4 outcomes of this event.

Now,

Probability that there are 0 heads in the event:

One event there is 0 heads = T T

Probability = 1/4

= 0.25

Now, events with one head are:

H T and T H

So,

Probability = 2/4

= 0.5

In the final event, we have 2 heads in one event = H H

This is an exercise in solving problems involving quadratic functions, which is an important topic in mathematics and is used in many fields, including physics, engineering, and economics. In general, one seeks to find the critical points of a quadratic function, such as the vertex or the roots, to understand the behavior of the function in different situations.

To find the vertex of a quadratic function, we use the canonical form of the quadratic equation, which is f(x) = a(x - h)^2 + k, where (h, k) are the coordinates of the vertex. It is also possible to find the vertex using the formula -b/2a, which is derived from the general form of the quadratic equation.

In addition to finding the vertex, it is also common to find the roots of a quadratic function, which are the values of x where the function vanishes. This can be done using the general formula of the quadratic equation or by completing the square.

f(x) = 2(x + 8)² - 2

First we write the quadratic function in standard form.

Using (a + b)² = a² + 2ab + b², expand the expression.

   f(x) = 2(x² + 16x + 64) - 2

We distribute the 2 to the terms that are between the parentheses.

  f(x) = 2x² + 32x + 128 - 2 ⇒ subtract 2

  f(x) = 2x² + 32x + 126

Now we identify the coefficients a and b of the quadratic function.

a = 2, b = 32

We find the x-coordinate of the vertex by substituting a = 2 and b = 2 into x = - (b)/(2a).

     x = - (32)/(2 × 2) = - 32/4 = -8

     x = -8

Find the y-coordinate of the vertex by evaluating the function for x = -8.

   f(x) = 2(x + 8)² - 2, x = -8

  We substitute x = -8 in the equation.

    f(-8) = 2(-8 + 8)² - 2

The sum of two opposite numbers is equal to 0. The Inverse Property of Addition states that the sum of two opposite numbers is equal to 0.

f(-8) = 2 x 0² - 2

0 raised any positive power is equal to 0. We remember that a power represents a repeated multiplication of the base.

Therefore, the power 0² means that 0 is multiplied by itself 2 times, resulting in 0.

f(-8) = 2 × 0 - 2

Any expression multiplied by 0 equals 0.

f(-8) = 0 - 2

Removing the 0 does not change the value, so we remove it from the expression.

  f(-8) = -2

The vertex of the graph of the quadratic function is at (-8, -2).

  (-8,-2)

The vertex of the quadratic function f(x) = 28(x + 8)² - 2 is (-8,-2), the last option being correct.

The null hypothesis would be that the mean tenure for CEO's is 8 years, while the alternative hypothesis would be that the mean tenure for CEO's is less than 8 years. This would be formulated as: Null hypothesis: μ = 8 years
Alternative hypothesis: μ < 8 years

The sample mean of 5.8 years is lower than the claimed mean of 8 years, suggesting that the shareholders' claim may not be valid. To test the validity of their claim, a hypothesis test can be conducted using the sample data and assuming a normal distribution of CEO tenure in the population.

To challenge the validity of the claim made by the shareholders, you can formulate a hypothesis test using the following steps:

Step 1: State the null hypothesis (H0) and alternative hypothesis (H1)
- Null hypothesis (H0): The population mean tenure for a CEO is at least 8 years (μ ≥ 8)
- Alternative hypothesis (H1): The population mean tenure for a CEO is less than 8 years (μ < 8)

Step 2: Collect and summarize the sample data
- Sample size (n): 52 companies
- Sample mean (x): 5.8 years
- Sample standard deviation (s): 5.4 years

Step 3: Since the population standard deviation is unknown and the sample size is large (n > 30), we can assume the sampling distribution is normally distributed and use a t-test to perform the hypothesis test.

Note that we cannot directly test the validity of the shareholders' claim based on the sample data alone. The hypothesis test will help determine whether there is enough evidence to reject the null hypothesis and support the alternative hypothesis, which would then challenge the claim made by the shareholders.
