What is the mean, and what does it tell you in terms of the problem?

Answers

Answer 1

The mean of the data is 3.85 using the stem-and-leaf plot.

It means the average feet that the heavy ball was thrown is 3.85 feet, which is the typical number.

How to calculate the Mean of a Data?

To find the mean of a data set that is represented by a stem-and-leaf plot, first, list out all the data values that are represented on the stem-and-leaf plot, add all the values, and divide by the number of values that were represented on the stem-and-leaf plot.

Given the stem-and-leaf plot, using the key, the data points represented are:

2.0, 2.1, 2.4, 3.1, 3.2, 3.6, 4.1, 4.3, 4.7, 5.1, 5.1, 6.5

Mean = [2.0 + 2.1 + 2.4 + 3.1 + 3.2 + 3.6 + 4.1 + 4.3 + 4.7 + 5.1 + 5.1 + 6.5]/12

Mean = 46.2/12

Mean = 3.85 feet

The mean of 3.85 feet means that the average distance that the heavy ball was thrown in feet is 3.85.

If the p-value is 0.023 from a hypothesis test is compared to a significance level of 0.05, what conclusion would we make?



Group of answer choices

A) Accept the null hypothesis.

B) Reject the alternative hypothesis.

C) Fail to reject the null hypothesis.

D) Reject the null hypothesis.

Answers

If the p-value is 0.023 from a hypothesis test is compared to a significance level of 0.05, the conclusion which we would make is: A) accept the null hypothesis.

What is a p-value?

A p-value is also referred to as the probability value and it can be defined as a probability which arises when the null hypothesis (H₀) is true of obtaining a sample result that is at least as unlikely as what is originally observed.

In Mathematics, the following rules are applicable to both a p-value and a hypothesis test:

Accept the null hypothesis when the p-value is greater than the significance level (alpha).Reject the null hypothesis when the p-value is less than the significance level (alpha).

In this context, we can logically deduce that the null hypothesis would be accepted because the p-value (0.023) is greater than a significance level of 0.05 and not statistically significant.

Differentiate the function with respect to x.

Answers

Using the Quotient Rule, the differentiate the function with respect to x is [tex]\frac{4x^3}{9x^8+24x^4+16}[/tex] .

In the given question,

We have to differentiate the given function with respect to x.

The given function is [tex]y=\frac{x^4+1}{3x^4+4}[/tex]

We have differentiate with respect to x.

The given function is in fraction format. So solving the given expression we use Quotient Rule

According to Quotient Rule

"A method for recognizing issues where one function is divided by another is the quotient rule."

The formula of Quotient Rule is

[tex]\frac{d}{dx}[\frac{f(x)}{g(x)}]=\frac{g(x)f'(x)-g'(x)f(x)}{(g(x))^2}[/tex]....................(1)

As we see in our function then f(x) = x[tex]^4+[/tex]1 and g(x) = 3x[tex]^4+[/tex]4

Before solving the function we find the value of f'(x), g'(x) and (g(x))[tex]^2.[/tex]

Now solving the f(x) for f'(x) with respect to x.

f(x) = x[tex]^4+[/tex]1

[tex]\frac{d}{dx}f(x)=\frac{d}{dx}(x^4+1)[/tex]

[tex]f'(x)=\frac{d}{dx}x^4+\frac{d}{dx}1[/tex]

We know that the differentiation of [tex]x^n=nx^{n-1}[/tex] and differentiation of constant value is zero.

So [tex]f'(x)=4x^{(4-1)}+0[/tex]

[tex]f'(x)=4x^3[/tex]

Now solving the g(x) for g'(x) with respect to x.

g(x) = 3x[tex]^4+[/tex]4

[tex]\frac{d}{dx}g(x)=\frac{d}{dx}(3x^4+4)[/tex]

[tex]g'(x)=3\frac{d}{dx}x^4+\frac{d}{dx}4[/tex]

We know that the differentiation of [tex]x^n=nx^{n-1}[/tex] and differentiation of constant value is zero.

[tex]g'(x)=3(4x^{(4-1)})+0[/tex]

[tex]g'(x)=3(4x^{3})[/tex]

[tex]g'(x)=12x^{3}[/tex]

Now finding the value of (g(x))[tex]^2.[/tex]

g(x) = 3x[tex]^4+[/tex]4

[tex](g(x))^4=(3x^4+4)^2[/tex]

Now using the formula of [tex](a+b)^2=a^2+2ab+b^2[/tex].

Now solving

[tex](g(x))^4=(3x^4)^2+2\times(3x^4)\times4+(4)^2[/tex]

Simplifying

[tex](g(x))^4=9x^8+24x^4+16[/tex]

Now putting the value of f'(x), g'(x) and (g(x))[tex]^2.[/tex] in the equation (1)

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{(3x^4+4)(4x^3)-(12x^3)(x^4+1)}{9x^8+24x^4+16}[/tex]

Simplifying

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{(3x^4(4x^3)+4(4x^3))-((12x^3)x^4+1(12x^3))}{9x^8+24x^4+16}[/tex]

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{(12x^{(4+3)}+16x^3)-(12x^{(3+4)}+12x^3)}{9x^8+24x^4+16}[/tex]

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{(12x^{7}+16x^3)-(12x^{7}+12x^3)}{9x^8+24x^4+16}[/tex]

Now solving the bracket

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{12x^{7}+16x^3-12x^{7}-12x^3}{9x^8+24x^4+16}[/tex]

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{16x^3-12x^3}{9x^8+24x^4+16}[/tex]

[tex]\frac{d}{dx}[\frac{x^4+1}{3x^4+4}]=\frac{4x^3}{9x^8+24x^4+16}[/tex]

Hence, the differentiate the function with respect to x is [tex]\frac{4x^3}{9x^8+24x^4+16}[/tex] .

What is surface area of cone?

  The region that a cone's surface occupies in three dimensions is known as the surface area of a cone. The whole area a cone's surface covers is known as the cone's surface area. The overall surface area will include the cone's lateral and base surfaces. A three-dimensional solid construction with a circular base is referred to as a cone. A cone can be thought of as a collection of irregularly shaped circular discs that have been stacked on top of one another while maintaining a constant ratio between the radii of the adjacent discs. It is the total of the cone's lateral area and base area.

Here the given ,

=> Height h= 12in

=> Radius r = 5 in

Using surface area of cone formula,

=> Surface area SA = [tex]\pi[/tex]r(r+ [tex]\sqrt{r^2+h^2}[/tex]) square unit.

=> surface area SA = 3.14*5(5+[tex]\sqrt{12^2+5^2}[/tex])

A firecracker is fired straight up into the air out of a window of a building. Its height, in feet, is given by
h - 16t² + 96t + 112, where t is the time, in seconds, the fircracker has been in the air.
At some point in its path it reaches a highest point.

Answers

Step-by-step explanation:

I assume our task is to find that point of time, when it reaches the highest point.

and the function is

h(t) = -16t² + 96t + 112

well, a maximum or minimum of a curve (function) is found as a zero solution of the first derivative of the function.

given the nature of the function, the extreme point has to be a maximum (the firecracker goes up and then down again).

h'(t) = -32t + 96

we are looking for the zero :

0 = -32t + 96

32t = 96

t = 3 seconds

so, after 3 seconds, the firecracker reaches its highest point, which is at

-16×3² + 96×3 + 112 = -16×9 + 96×3 + 112 =

= -144 + 288 + 112 = 256 ft

FYI - we know for x = 0 (the starting point) the height of the starting window was 112 ft.

Answers

The measure of side AC in the triangle is 2.7 m

Calculating measures of sides in similar triangles

From the question, we are to determine the measure of AC

From the given information, we have that ΔADC is similar to ΔCDB

Thus,

We can write that

|DC| / |DB| = |AC| / |CB|

From the diagram,

|DC| = 5.5 m

|DB| = 6.3 m

|AC| = h

|CB| = 3.1 m

Then,

5.5 / 6.3 = h / 3.1

∴ h = (5.5 × 3.1) / 6.3

h = 17.05 / 6.3

h = 2.70635 m

h ≈ 2.7 m

A drawer of shirts contains 3 solid red, 2 striped red, 4 solid blue, and 3 striped green. What is the probability of picking a shirt that is red or striped?

Answers

The probability of picking a shirt that is red or striped is 2/3.

Given, that a drawer of shirts contains 3 solid red, 2 striped red, 4 solid blue, and 3 striped green.

We have to find the probability of picking a shirt that is red or striped,

P(R ∪ S) = P(R) + P(S) - P(R∩S)

where, R be the event that the shirt is red.

and S be the even that the shirt is striped.

P(R) = 5/12 (as, there are 5 red shirts)

P(S) = 5/12 (as, there are 5 striped shirts)

P(R∩S) = 2/12 (as, there are 5 striped red shirts)

P(R ∪ S) = 5/12 + 5/12 - 2/12

P(R ∪ S) = 8/12

P(R ∪ S) = 2/3

The probability of picking a shirt that is red or striped is 2/3.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A town's populace is 43,200. Around 125 individuals move out of the town every month. Every month, 175 individuals on the normal move into town. A close by the town has a populace of 45,900. It has nobody moving in and a normal of 175 individuals moving away consistently.

Let y be the total population and x be the number of months. Then the equations are given as,

y = (175 - 125)x + 43200

y = 50x + 43200           ...1

y = -175x + 45900        ...2

From equations 1 and 2, then we have

50x + 43200 = - 175x + 45900

50x + 175x = 45900 - 43200

225x = 2700

x = 2700 / 225

x = 12

The months will the populations of the towns be​ equal will be 12.

Eve needed to collect the eye color of 50 random people for a high school statistics project. Being shy, she felt more comfortable collecting the data from 20 arbitrary classmates, 12 arbitrary neighbors, and 18 arbitrary members of her bible study group. Upon hearing of her data collection process, her project partner, Adam, stated that all the data was useless. His rationale was that the data was not truly random since Eve knew the people in her sample. Adam believed random data must come from strangers. Do you believe Adam is correct or is Eve's data actually random? Explain your position.

Answers

Eve's data is a random sampling since she picked the participants randomly.

What is a random sampling?

A simple random sample is a subset of a population chosen at random. This sampling strategy gives each person of the population an exact equal chance of being chosen, reducing the likelihood of selection bias.

To be considered a truly random sample, every subject in your target demographic must have an equal chance of being chosen. Conducting a study to estimate the length of time college students workout at your campus each week is an example of breaking this assumption.

In this case, Eve needed to collect the eye color of 50 random people for a high school statistics project and she felt more comfortable collecting the data from 20 arbitrary classmates, 12 arbitrary neighbors, and 18 arbitrary members of her bible study group.
