How do you graph a slope of 3?

Answers

The graph of a slope of 3 is a  straight line.

What is a slope?It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass. Any two distinct places along the line can be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the "vertical change" to the "horizontal change" in each case. The difference between the line's y and x coordinate changes is known as the slope of the line.Here, let us graph a line with slope = 3

        Let us assume the co-ordinates

              [tex](x _1, y_1) = (2,1)\\(x _2, y_2) = (5,10)\\\\\text{We know} ,\\\\m =\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\m = \frac{10-1}{5-2} \\[/tex]

              m = 9/ 3

What is the median of the following 3 4 5 3 6 7 2?

Answers

To find the median of a set of numbers, you first need to put the numbers in order from smallest to largest. Once the numbers are ordered, the median is the middle number in the list.

In this case, the ordered list of numbers is: 2, 3, 3, 4, 5, 6, 7.

The median of this list is 4.

The mathematical median is what?

Sorting all the data points and selecting the central one are required to determine the middle number (or if there are two middle numbers, taking the mean of those two numbers). Example: The number 4 is in the middle when the numbers are grouped (1, 4, 7), making it the median of the numbers (4, 1 and 7).

How can you determine a median?

By summing up the center values and dividing them by two, you may obtain the mean and, from there, the median.

The correct solution of the given function is g'(t)=20 for some t in the interval. The correct option is (B).

Definition of function- Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in sciences.

Given that g(10)= 220, g(0)=20

Explanation: A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

For a given function, y = F(x), if the value of y is increasing on increasing the value of x, then the function is known as an increasing function and if the value of y is decreasing on increasing the value of x, then the function is known as a decreasing function.

So putting values in condition of differentiation for increasing function we get:

=[tex]\frac{g(10)-g(0)}{10-0}[/tex]=[tex]\frac{220-20}{10}[/tex]=[tex]\frac{200}{10}[/tex]=20

The correct solution for given function is g'(t) = 20 for some t in the interval.

Why is the AAA similarity test not necessary?

Answers

Knowing merely angle-angle-angle (AAA) does not work, because it can result in triangles that are similar but not congruent.

A set of triangles must have equal sides and angles in order for them to be congruent. The sides of the triangles may or may not be equal in the case of a triangle with all of the corresponding angles equal, or the AAA condition. Only if the two triangles are similar would the congruence be true for two triangles with identical respective angles.

For their class project, a group of statistics students decide to survey the student body to assess opinions about the proposed new student center. Their sample of 200 contained 50 first-year students, 50 sophomores, 50 juniors, and 50 seniors.

Answers

The sample size of 200 can be represented by the equation n1 + n2 + n3 + n4, where n1, n2, n3, and n4 represent the number of first-year, sophomore, junior, and senior students surveyed, respectively.

The sample of 200 students surveyed by the statistics students was composed of 50 first-year students, 50 sophomores, 50 juniors, and 50 seniors. This could be represented by the following formula:

Sample Size = 50 First-Years + 50 Sophomores + 50 Juniors + 50 Seniors

In order to break down this sample size into a mathematical formula, the students can use the following equation:

Sample Size (SS) = n1 + n2 + n3 + n4

Where n1, n2, n3, and n4 represent the number of first-year, sophomore, junior, and senior students surveyed, respectively.

Therefore, using the original sample size, the equation would be:

SS = 50 First-Years + 50 Sophomores + 50 Juniors + 50 Seniors

SS = n1 + n2 + n3 + n4

SS = 50 + 50 + 50 + 50

SS = 200

This shows that the sample size of 200 can be represented by the equation n1 + n2 + n3 + n4, where n1, n2, n3, and n4 represent the number of first-year, sophomore, junior, and senior students surveyed, respectively.

Which description of the graph of the linear inequality y ≥ 7x 4 is correct?

Answers

The answer to the above question will be as follows:

The correct option is option c.) The graph will be a solid line with a y-intercept of seven and a slope of negative four. The graph will be shaded above the line.

We solve the question in the following way,

Given inequality is y≥7x- 4

Let us first consider the linear equality of the equation as

y= 7x- 4

When we consider this with the general slope form of a straight line given by: y=mx+c, we get

m=7 and c= -4

Now, we know that for the ‘greater than or smaller than equal to’ sign, the graph is mapped using a solid line and is shaded away from the origin of the graph (0,0).

Thus for this graph, we will use a solid line to represent the line y=7x- 4 and shade the graph above the line. Therefore option (c.) is correct.

Answers

Answer:

  (c)  two right triangles, each with both legs 40 inches long

Step-by-step explanation:

You want to know which pair of triangles are congruent, given their descriptions.

Congruent triangles

There are basically 4 theorems that allow you to claim congruence of triangles:

  AAS, ASA, SAS, SSS

A fifth one applies to right triangles only: HL.

These tell you that you need to have three matching parts: 3 sides, 2 sides and the angle between (except right triangle), or 1 side and 2 angles.

Choices

An isosceles triangle with only one or two sides defined is not sufficient.

A right triangle with only the hypotenuse defined is not sufficient.

A right triangle with two legs and the (right) angle between them has a sufficient number of matching parts to be able to claim congruence to another triangle similarly defined.

The prime factors of 28 is 2 and 7.

Rewrite 28 as the product prime factors:

28 = 7 × 2 × 2.

The prime factors of 8 is 2.

Rewrite 8 as the product prime factors:

8 = 2 × 2 × 2.

Replace 28 = 7 × 2 × 2 and 8 = 2 × 2 × 2 in the given expression:

28x − 8

What is the solution to the system of linear equations?

Step-by-step explanation:

The equations must be derived from the graph:

First, find the slope of f(x):

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] let [tex](x_1,y_1)=(-3,3)[/tex] and [tex](x_2,y_2)=(3,1)[/tex]

[tex]m=\frac{(1)-(3)}{(3)-(-3)}\\m=\frac{-2}{6}\\m=-\frac{1}{3}[/tex]

Then use [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-3=-\frac{1}{3}[x-(-3)]\\y-3=-\frac{1}{3}x-1\\y=-\frac{1}{3}x+2\\f(x)=-\frac{1}{3}x+2[/tex]

For g(x), let:

[tex](x_1,y_1)=(-3,0)\\(x_2,y_2)=(0,2)[/tex]

[tex]m=\frac{(2)-(0)}{(0)-(-3)}\\m=\frac{2}{3}[/tex]

[tex]y-0=\frac{2}{3}[x-(-3)]\\y=\frac{2}{3}x+2\\g(x)=\frac{2}{3}x+2[/tex]

Now, to solve for x, allow the two expressions written in terms of x equal each other.

[tex]-\frac{1}{3}x+2=\frac{2}{3}x+2\\(-\frac{1}{3}x+2)+\frac{1}{3}x=(\frac{2}{3}x+2)+\frac{1}{3}x\\2=x+2\\(2)-2=(x+2)-2\\x=0[/tex]

To solve for y, substitute 0 for x in f(x):

[tex]y=-\frac{1}{3}x+2\\y=-\frac{1}{3}(0)+2\\y=0+2\\y=2[/tex]

So, the solution to this system of equations would be the ordered pair (0,2).  This solution is seen on the graph as the intersection of the two lines.

What can you say about the number of dresses each one of them will have after Rohan's birthday? Which Euclid's axiom is used to answer this question?​

Answers

Answer:

Step-by-step explanation:

Rohan is a generous person who cares deeply for his maid and her two children. On Rohan's birthday, he plans to give both of them the same number of dresses. This situation can be solved using Euclid’s axiom that states “things which are equal to the same thing are also equal to one another”. Therefore, after Rohan's birthday each child will have an equal number of dresses as they were given an identical amount from him.

This kind gesture by Rohan demonstrates his commitment towards taking care of those around him and providing fairness in all situations possible - it serves as a reminder that we should always strive for equality among people regardless of their backgrounds or social statuses in life! By following this axiom, everyone can benefit from having access to resources no matter what their circumstances may be; thus creating a more equitable society overall.

The act done by Rohana is praiseworthy and must serve as an example for others too so they understand how important it is treat everyone equally regardless if they belong to different castes or classes in our society! We should take measures like these on regular basis so that true justice prevails everywhere without any discrimination whatsoever- this would make sure everybody has access basic necessities such us clothes just like Rohana provided his maid's kids with new sets on his own birthday!

[tex]S_n=(a+(n-1)d)+(a+(n-2)d)+(a+(n-3)d)+...+(a+2d)+(a+d)+a[/tex]

Add the two expressions for Sₙ:

[tex]2S_n=(2a+(n-1)d)+(2a+(n-1)d)+(2a+(n-1)d)+...+(2a+(n-1)d)[/tex]

Therefore, the term (2a + (n – 1)d) has been repeated n times:

[tex]2S_n=n(2a+(n-1)d)[/tex]

Divide both sides by 2:

[tex]S_n=\dfrac{1}{2}n(2a+(n-1)d)[/tex]

[tex]S_n=\dfrac{1}{2}n(a+a+(n-1)d)[/tex]

Replace  a with  a₁  (first term) and a + (n – 1)d  with  aₙ (last term):

[tex]S_n=\dfrac{1}{2}n(a_1+a_n)[/tex]

To find the sum of the series 1 + 2 + 3 + ... + 500, substitute the following values into the formula:

a₁ = 1aₙ = 500n = 500

Therefore:

[tex]\implies S_{500}=\dfrac{1}{2}(500)(1+500)[/tex]

[tex]\implies S_{500}=250(501)[/tex]

[tex]\implies S_{500}=125250[/tex]

what is the inequality:the sign below the troll for driving on alligator alley. Passenger cars troll:2.50. write an inequality to represent the number of times someone can drive on alligator alley with $15.

Answers

Answer:

2.5n ≤ 15

Step-by-step explanation:

Let n = number of times

Each toll is $2.50, so the toll for n trips is n times $2.50, or 2.5n.

The total amount of money available is $15, so 2.5n must be less than or equal to 15.

Inequality:

2.5n ≤ 15

(In case you're asked next, here is the solution of the inequality:

Divide both sides by 2.5.

2.5n/2.5 ≤ 15/2.5

n ≤ 6

A person can drive up to 6 times with $6.)

What is the median of 10?

Answers

The required median of the first ten natural numbers is 5.5.

The median is the number in the middle of a list of numbers in ascending order, from lowest to highest.

The median is the middlemost element if the total number of elements in the list is odd, and the median is the average of the middlemost two values if the total number of elements in the list is even.

The list of the first 10 natural numbers is: 1,2,3,4,5,6,7,8,9,10

Here is the total number of elements in the list is even.

And the two middlemost elements are 5 and 6.

The required median is: 5+6 /2 = 11/2 = 5.5

Hence, the required median of the first ten natural numbers is 5.5.

Assuming a 10% rate of orders that are incorrect. The accuracy rate seems to be satisfactory.

Definition of accuracy-The accuracy formula provides accuracy as a difference of error rate from 100%. To find accuracy we first need to calculate the error rate. And the error rate is the percentage value of the difference of the observed and the actual value, divided by the actual value.

Given: A study of the accuracy of fast food drive-through orders, one restaurant had 37 orders that were not accurate among 333 orders observed. Significance level-0.05

Explanation: Assuming a 10% rate of orders that are incorrect. The accuracy rate seems to be satisfactory.

Let a be the population proportion of the orders that were not accurate.

Then according to the claim we have,

[tex]H_{o} :[/tex]  [tex]p[/tex] = [tex]0.10[/tex]

[tex]H{a} :p[/tex] ≠ [tex]0.10[/tex]

Since the alternative hypothesis is two-tailed so the hypothesis test is a  two-tailed test.

For example,

n = 333

The proportion of the orders that were not accurate =  [tex]p{'}[/tex][tex]=\frac{37}{333}[/tex] ≈[tex]0.112[/tex]

Test statistics for population proportion:-

Assuming a 10% rate of orders that are incorrect. The accuracy rate seems to be satisfactory.

Let a be the population proportion of the orders that were not accurate.

Then according to the claim we have,

[tex]H_{o} :p=0.10[/tex]

[tex]H_{a} :p[/tex] ≠ [tex]0.10[/tex]

Since the alternative hypothesis is two-tailed so the hypothesis test is a  two-tailed test.

For example,

n = 333

The proportion of the orders that were not accurate =  [tex]p^{'} =\frac{37}{333}[/tex] ≈ [tex]0.112[/tex]

Test statistics for population proportion:-

[tex]z=\frac{p-p'}\sqrt{p(1-p)/\sqrt{n}[/tex][tex]=\frac{0.112-0.10}\sqrt{0.10(0.90)}/ {333}[/tex] ≈ [tex]0.75[/tex]

By using the standard normal distribution table,

The p-value : [tex]2(z > 0.75)=2.55[/tex]

Since the p-value is greater than the significance level (0.05), so we do not reject the null hypothesis.

Hence, we conclude that the accuracy rate appears to be​ acceptable and satisfactory.
