if a population function x has mean M(x)=2 and M(x^2)=8 ,find its standard deviation

Answers

The standard deviation of the population function x is 2.

We have,

To find the standard deviation of the population function x, we need the mean M(x) and the mean of the squared values M(x²).

So,

Standard Deviation = √[M(x²) - (M(x))²]

Given that M(x) = 2 and M(x²) = 8, we can substitute these values into the formula:

Standard Deviation = √[8 - (2)²]

Standard Deviation = √[8 - 4]

Standard Deviation = √4

Standard Deviation = 2

Therefore,

The standard deviation of the population function x is 2.

if f(x)=-2x, g(x)=3x-7, and h(x)=2x^2-10, fill in the following chart

Answers

The values of Composite function are:

f(g(-1)) = 20

h[g(4)] = 40

g[f(5)] = -37

f[h(-4)] = -44

g[g(7)] = 35

h[f(1/2)] = -8

We have, f(x) = -2x, g(x) = 3x-7 and h(x)= 2x² -10

f(g(-1)):

First, substitute -1 into g(x): g(-1) = 3(-1) - 7 = -3 - 7 = -10.

Next, substitute the result into f(x): f(-10) = -2(-10) = 20.

Therefore, f(g(-1)) = 20.

h[g(4)]:

First, substitute 4 into g(x): g(4) = 3(4) - 7 = 12 - 7 = 5.

Next, substitute the result into h(x): h(5) = 2(5^2) - 10 = 2(25) - 10 = 50 - 10 = 40.

Therefore, h[g(4)] = 40.

g[f(5)]:

First, substitute 5 into f(x): f(5) = -2(5) = -10.

Next, substitute the result into g(x): g(-10) = 3(-10) - 7 = -30 - 7 = -37.

Therefore, g[f(5)] = -37.

f[h(-4)]:

First, substitute -4 into h(x): h(-4) = 2(-4²) - 10 = 2(16) - 10 = 32 - 10 = 22.

Next, substitute the result into f(x): f(22) = -2(22) = -44.

Therefore, f[h(-4)] = -44.

g[g(7)]:

First, substitute 7 into g(x): g(7) = 3(7) - 7 = 21 - 7 = 14.

Next, substitute the result into g(x) again: g(14) = 3(14) - 7 = 42 - 7 = 35.

Therefore, g[g(7)] = 35.

h[f(1/2)]:

First, substitute 1/2 into f(x): f(1/2) = -2(1/2) = -1.

Next, substitute the result into h(x): h(-1) = 2(-1²) - 10 = 2(1) - 10 = 2 - 10 = -8.

O is the center of the regular decagon below. Find its perimeter. Round to the nearest tenth if necessary.

Answers

Answer:

65 units

Step-by-step explanation:

solution Given:

apothem(a)=10

no of side(n)= 10

First, we need to find the length of one side (s).

We can find the length of one side using the following formula:

[tex]\boxed{\bold{s = 2 * a * tan(\frac{\pi}{n})}}[/tex]

substituting value:

[tex]\bold{s = 2 * 10 * tan(\frac{\pi}{10})=6.498}[/tex]   here π is 180°

Now

Perimeter: n*s

substituting value:

Perimeter = 10*6.498= 64.98 in nearest tenth 65 units

Therefore, the Perimeter of a regular decagon is 65 units.

Answer:

65.0 units

Step-by-step explanation:

A regular decagon is a 10-sided polygon with sides of equal length.

To find its perimeter, we first need to find its side length (s).

As we have been given its apothem, we can use the apothem formula to find an expression for side length (s).

[tex]\boxed{\begin{minipage}{5.5cm}\underline{Apothem of a regular polygon}\\\\$a=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\where:\\\phantom{ww}$\bullet$ $s$ is the side length.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}[/tex]

Given the apothem is 10 units and the number of sides is 10, substitute a = 10 and n = 10 into the formula and solve for s:

[tex]10=\dfrac{s}{2 \tan \left(\dfrac{180^{\circ}}{10}\right)}[/tex]

[tex]10=\dfrac{s}{2 \tan \left(18^{\circ}\right)}[/tex]

[tex]s=20 \tan \left(18^{\circ}\right)[/tex]

The perimeter (P) of a regular polygon is the product of its side length and the number of sides. Therefore, the perimeter of the given regular decagon is:

[tex]P=s \cdot n[/tex]

[tex]P=20 \tan \left(18^{\circ}\right) \cdot 10[/tex]

[tex]P=200 \tan \left(18^{\circ}\right)[/tex]

[tex]P=64.9839392...[/tex]

[tex]P=65.0\; \sf units\;(nearest\;tenth)[/tex]

Therefore, the perimeter of a regular decagon with an apothem of 10 units is 65.0 units, to the nearest tenth.

Effect:

Intersects x-axis at x = -2/5 =0 with a steep curve

The zeros, multiplicity, and effect of the function f(x) = 3x(x - 1)˚ (5x + 2)³, we need to factor the expression.

First, let's identify the zeros by setting the expression equal to zero and solving for x:

3x(x - 1)˚ (5x + 2)³ = 0

Setting each factor equal to zero:

3x = 0 --> Zero: x = 0

x - 1 = 0 --> Zero: x = 1

(5x + 2)³ = 0 --> Zero: x = -2/5

Now, let's determine the multiplicity and effect of each zero:

Zero:

x = 0

To determine the multiplicity, we look at the exponent of the factor (x) in the expression.

The factor x has a multiplicity of 1 since it appears once.

The effect of this zero is that it is a root of the function and causes the graph to intersect the x-axis at x = 0.

Zero:

x = 1

Similar to the previous case, the factor (x - 1) has a multiplicity of 1 since it appears once.

The effect of this zero is that it is a root of the function and causes the graph to intersect the x-axis at x = 1.

Zero:

x = -2/5

The factor (5x + 2) has a multiplicity of 3 because it appears cubed (exponent of 3).

The effect of this zero is that it is a root of the function and causes the graph to intersect the x-axis at x = -2/5 with a steep curve, as it is raised to the power of 3.

Write the equation of a parabola whose directrix is x = -2 and has a focus at (8,-8).

Answers

The equation of the parabola is (x - 3)² = 20(y - k)

Given data ,

To write the equation of a parabola given its directrix and focus, we can use the standard form for a parabola with a vertical axis of symmetry:

(x - h)² = 4p(y - k)

where (h, k) represents the vertex of the parabola, and the distance between the vertex and the focus is equal to the distance between the vertex and the directrix.

In this case, the directrix is x = -2 and the focus is located at (8, -8). Since the directrix is a vertical line, the parabola has a horizontal axis of symmetry.

And , the vertex lies on the axis of symmetry, which is the line equidistant between the directrix and the focus. In this case, the axis of symmetry is the vertical line x = (8 + (-2)) / 2 = 3.

So, the vertex of the parabola is (3, k), where k is yet to be determined

Next, we need to find the value of p, which represents the distance between the vertex and the focus. Since the focus is at (8, -8), and the vertex is at (3, k), the distance between them is given by

p = 8 - 3 = 5

Now, substituting the values into the standard form equation, we have:

(x - 3)² = 4(5)(y - k)

Simplifying further:

(x - 3)² = 20(y - k)

Hence , the equation of the parabola is (x - 3)^2 = 20(y - k), where k is the y-coordinate of the vertex

Use the associative law of multiplication to write an equivalent expression

(12x)y

Answers

Using  the associative law of multiplication we get this two solution of the given expression: (12x)y = (12 * x) * y , (12x)y = 12 * (x * y)

The associative law of multiplication states that when multiplying three or more numbers, the product is the same regardless of the order in which the numbers are grouped. In other words, it doesn't matter which numbers we multiply first, the result will be the same.

Using the associative law of multiplication, we can group the factors in any way we like. Therefore, we can write an equivalent expression to (12x)y by changing the grouping of factors.

One way to group the factors is to group the two numerical coefficients (12 and y) together.

Another way to group the factors is to group the variable x and the coefficient y together.

Both of these expressions are equivalent to (12x)y and they all follow the associative law of multiplication.

What is the slope of a graph of a straight line?

The slope of the graph of a straight line is the ratio of the rise to the run on the line.

The slope of a graph with a slope of 1 has an increase in the y-value of 1 for each increase in the x-value of 1

Slope = 1 = Δy/Δx

When the slope is greater than 1, we get;

Δy/Δx > 1, therefore Δy is larger than 1 when Δx is 1.

Similarly, the slope of a graph with a slope of 2 has an increase in the y-value of 2 for each increase in the x-value of 1

Slope = 2 = Δy/Δx

When the slope is less than 1, we get;

Δy/Δx < 2, therefore Δy is less than 2 when Δx is

The lines in the graph that have a slope greater than 1 but less than 2 are therefore the graphs with the coordinates;

Line 3; (0, 0), (4, 6); Slope = 6/4 = 3/2, therefore; 1 < slope = 3/2 < 2

Part C. Jack also likes to collect buttons. He has 5 bags of button The fewest number of buttons in a bag is 21. The greatest number of buttons in a bag is 29 The mean number of buttons in the bags is 27. There are two modes for the number of buttons in each bag. How many buttons are in each of Jack's five bags? ​

Answers

To find the number of buttons in each of Jack's five bags, we can use the information given to us and solve for the unknowns. Let's start by finding the total number of buttons:

Total number of buttons = Mean number of buttons × Number of bags

Total number of buttons = 27 × 5

Total number of buttons = 135

Since we know the fewest and greatest number of buttons in a bag, we can find the range:

Range = Greatest number of buttons - Fewest number of buttons

Range = 29 - 21

Range = 8

Now, we can set up two equations to find the two modes:

Mode 1 + Mode 2 + 3 × 27 = 135 (sum of all bags)

Mode 2 - Mode 1 = 8 (difference between the two modes)

Solving these equations simultaneously, we get:

Mode 1 = 23

Mode 2 = 31

Therefore, the number of buttons in each of Jack's five bags is:

Bag 1: 21 buttons

Bag 2: 23 buttons

Bag 3: 25 buttons

Bag 4: 27 buttons

Bag 5: 29 buttons

The equation of the circle with center (-4, 4) and passing through (-2, 4) is [tex](x + 4)^2 + (y - 4)^2 = 4.[/tex]

We have,

To determine the equation of a circle, we need the center coordinates and the radius. The center coordinates are given as (-4, 4), and we have a point on the circle as (-2, 4).

The distance between the center (-4, 4) and the point on the circle (-2, 4) represents the radius of the circle.

Using the distance formula.

[tex]radius = √[(x_2 - x_1)^2 + (y_2 - y_1)^2]\\= \sqrt{(-2 - (-4))^2 + (4 - 4)^2}\\= \sqrt{2^2 + 0^2}\\= \sqrt{4}\\= 2[/tex]

Now that we have the center coordinates (-4, 4) and the radius 2, we can write the equation of the circle in standard form:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Substituting the values:

[tex](x - (-4))^2 + (y - 4)^2 = 2^2\\(x + 4)^2 + (y - 4)^2 = 4[/tex]

The triangles are congruent if two sides and the included angle of one triangle are equivalent to the corresponding sides and angle of another triangle.

From A, we can see that ΔFEQ is similar to ΔRSQ because the ration of their sides are similar. That is

What are three consecutive multiples of 3 if 2/3

Answers

The three consecutive multiples of 3 are 15, 18 and 21

To solve this problem

First, let's determine three successive multiples of 3:

The subsequent two would be "x+3" and "x+6" if we call the initial number "x".

Since we are aware that the third number (x+6) is one more than the first two numbers (x + x+3), we can write the following equation:

2/3(x + x+3) = (x+6) + 1

Simplifying this equation, we get:

2/3(2x+3) = x+7

Multiplying both sides by 3, we get:

2(2x+3) = 3(x+7)

Expanding and simplifying, we get:

4x + 6 = 3x + 21

Subtracting 3x and 6 from both sides, we get:

x = 15

Therefore, the three consecutive multiples of 3 are 15, 18 and 21

) Assume that a simple random sample has been selected from a normally distributed population and test the given claim at α = 0.05. State the claim mathematically. Identify the null and alternative hypotheses, test statistic, critical region(s), and the decision regarding the null hypothesis. State the conclusion that addresses the original claim. A local group claims that police issue at least 60 speeding tickets a day in their area. To prove their point, they randomly select two weeks.

We cannot conclude that there are more than 70,000 defined words in the dictionary.

To test the claim that there are more than 70,000 defined words in the dictionary, we can set up the null and alternative hypotheses as follows:

Null Hypothesis (H0): The mean number of defined words on a page is 48.0 or less.

Alternative Hypothesis (H1): The mean number of defined words on a page is greater than 48.0.

So, sample mean

= (59 + 37 + 56 + 67 + 43 + 49 + 46 + 37 + 41 + 85) / 10

= 510 / 10

= 51.0

and, the sample standard deviation (s)

= √[((59 - 51)² + (37 - 51)² + ... + (85 - 51)²) / (10 - 1)]

≈ 16.23

Next, we calculate the test statistic using the formula:

test statistic = (x - μ) / (s / √n)

In this case, μ = 48.0, s ≈ 16.23, and n = 10.

test statistic = (51.0 - 48.0) / (16.23 / √10) ≈ 1.34

With a significance level of 0.05 and 9 degrees of freedom (n - 1 = 10 - 1 = 9), the critical value is 1.833.

Since the test statistic (1.34) is not greater than the critical value (1.833), we do not have enough evidence to reject the null hypothesis.

Therefore, based on the given data, we cannot conclude that there are more than 70,000 defined words in the dictionary.

If a wheelchair access ramp has to have an angle of elevation no more than 4.8 degrees and it has to rise 18 inches above the ground, how long must the ramp be?

Answers

The wheelchair access ramp must be 216.09 inches long.

To find the length of the wheelchair access ramp, we can use trigonometry.

The tangent function relates the angle of elevation to the ratio of the opposite side (height) to the adjacent side (length of the ramp).

Let's denote the length of the ramp as "x".

The height of the ramp is given as 18 inches.

Using the tangent function:

tan(angle of elevation) = height/length of the ramp

tan(4.8 degrees) = 18/x

To solve for x, we can rearrange the equation:

x = 18 / tan(4.8 degrees)

Using a calculator to evaluate the tangent of 4.8 degrees:

x = 18 / 0.08331

x= 216.09

On a coordinate plane, a parabola opens down. It goes through (negative 6, 0), has a vertex at (negative 4, 4), and goes through (negative 2, 0).

Which statement about the function is true?

The function is increasing for all real values of x where
x < –4.
The function is increasing for all real values of x where
–6 < x < –2.
The function is decreasing for all real values of x where
x < –6 and where x > –2.
The function is decreasing for all real values of x where
x < –4.

Answers

The statement about the function is: "The function is decreasing for all real values of x where x < -4." D.

The given information tells us that the graph represents a downward-opening parabola.

The vertex of the parabola is located at (-4, 4) indicates that this point is the highest point on the graph.

As we move to the left of the vertex, the function values decrease, indicating a decreasing trend.

Moreover, the graph passes through the point (-6, 0), which lies to the left of the vertex.

This confirms that the function is decreasing for all real values of x less than -4, including x < -6.

On the other hand, the graph also passes through the point (-2, 0), which lies to the right of the vertex.

This does not impact the conclusion that the function is decreasing for x < -4, as the graph's behavior to the right of the vertex is not relevant to this particular statement.

Based on the given information and the properties of the downward-opening parabola, we can conclude that the function is decreasing for all real values of x where x < -4.

Answer:

its b4 + 7b3 + 4b2 + b5 + 7b4+ 4b3= b5+8b4+11b3+4b2

Answer:

When multiplying, add the exponents, (example) remember if there is "7b" the exponent is one.

Multiply b^2 * b^3 = b^5  (add the exponent 2 + 3 = 5)

Multiply 7b * b^3 = 7b^4 (the exponent of 7b is one, add 1 + 3 for the exponent to become 4)

Multiply 4 * b^3 = 4b^3 (4 doesn't have a variable, the exponent will be 3)

b^2 * b*2 = b^4 (add exponents)

7b * b^2 = 7b^3 (add the exponents 1 + 2)

4 * b^2 = 4b^2

              b^2             +               7b             +        4

In your drawer you have 10 white socks and 14 black socks. You choose one sock from the drawer and then a second sock (without replacement.)
Event A: You choose a black sock.
Event B: You choose a black sock.
Tell whether the events are independent or dependent. Explain your reasoning.

Answers

The events A and B are dependent events.

The probability of event B will be different from the initial probability of selecting a black sock (event A).

Two events are considered independent if the outcome of one event does not affect the probability of the other event.

The outcome of event A (choosing a black sock) directly affects the probability of event B (choosing a black sock again).

To explain further, let's consider the initial scenario:

You have 10 white socks and 14 black socks in your drawer.

The total number of socks is 24.

The first sock, there are two possibilities:

Either it is a black sock or a white sock.

If event A occurs and you select a black sock, the total number of black socks in the drawer decreases to 13, while the total number of socks decreases to 23.

If event B to occur (selecting a black sock again), the probability is now influenced by the fact that you have one less black sock and one less sock in the drawer.

The probability of event B will be different from the initial probability of selecting a black sock (event A).

The outcome of event A affects the probability of event B, the two events are dependent.

The base of the mountain is 6,500 feet above sea level and lineAB measures 230 feet across. Given that the measurements for angleQAP is 20° and angleQBP is 35°, how far above sea level is peak P? Express your answer to the nearest foot.

Answers

The required measure of point P above the sea level is 6717.22 feet.

Given that,

A is known to be 6,500 feet above sea level; AB = 230 feet.

And, The angle at A looking up at P is 20°.

The angle at B looking up at P is 35°.

Since, These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

Here,

Let the horizontal distance between A and Q be x and the vertical distance between P and Q be h.

Now,

tan20 = h / x

034x = h

Now,

tan35 = [230 + h]/x

0.7x = 230 + 0.34x

x = 636.89

Now,

h = 0.34 x 636.89

h = 217.2

Now,

The measure of peak P above sea level = 217.2 + 6500 = 6717.22

Thus, the required measure of point P above the sea level is 6717.22 feet.
