Answer 1

Answer:

[tex]\displaystyle y = -3x + 9[/tex]

Step-by-step explanation:

First, find the rate of change of the line:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}[/tex]

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

[tex]\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}[/tex]

Two lines have the same slope and y-intercept. Describe the graph of the system of equations representing the two lines.

Answers

Answer:

Parallel lines.

Step-by-step explanation:

If the two linear equations have the same slope (and the SAME y-intercept), the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions (intersecting everywhere.)

If two equations have the same slope and the same y-intercept, then they are the same line and an infinite solution .

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

We have three cases in terms of slope and intercept:

The system has precisely one solution if the slopes of the two lines differ (whether the lines have the same intercept or different intercepts).There exists an infinite number of solutions to the system if they share the same slope and intercept, making them the same line.If they are parallel and have different intercepts but the same slope, there is no solution.

So, The identical numerical values used for x and y in the first solution will also work for the second because these lines have an infinite number of solutions.

Using the rule:

[tex]x {}^{n} .x {}^{m} = x {}^{n + m} [/tex]

Similarly:

[tex]x { }^{ \frac{1}{2} } .x {}^{ \frac{ - 1}{6} } .x {}^{ \frac{ - 5}{2} } = x {}^{ \frac{1}{2} - \frac{1}{6} - \frac{5}{2} } [/tex]

We have to achieve a common denominator which is 6 here:

[tex]x {}^{ \frac{3 - 1 - 15}{6} } =x {}^{ \frac{ - 13}{6} } [/tex]

To change our exponent to positive:

[tex]x {}^{ \frac{ - 13}{6} } = \frac{1}{x {}^{ \frac{13}{6}}} = \frac{1}{ \sqrt[6]{x {}^{13} } } = \frac{1}{x \sqrt[6]{x} } [/tex]

A dairy researcher has developed a new technique for culturing cheese that supposedly ages the cheese faster than the traditional methods, without affecting other properties like texture or taste. To implement this new technique, the cheese company would need to initially spend millions of dollars retrofitting their manufacturing plant. But if it does actually reduce the aging time of their cheese, even marginally, it will lead to higher profits for the company over time.In an experiment the researcher uses both methods of culturing cheese to see if the new method significantlyreduces aging time.a.Write an appropriate null and alternative hypothesis for this experiment. (2pt)

Answers

Answer:

Null hypothesis: There is no significant difference in aging time of old methods of culturing cheese and the new method of culturing cheese.

H0:μ1=μ2.

Alternative hypothesis: The new method of culturing cheese reduces aging time as compared to old method of culturing cheese

Ha:μ1>μ2.

Step-by-step explanation:

We are interesting in investigating that whether the the new method of culturing cheese significantly reduces aging time compared to old method of culturing cheese. Null hypothesis always contain equality so, in null hypothesis we make the statement of no difference among both methods of culturing cheese. So, null hypothesis can be written as

Null hypothesis: There is no significant difference in mean aging time of old methods of culturing cheese and the new method of culturing cheese.

Or symbolically it can be written as

H0:μ1=μ2

whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.

Alternative hypothesis includes difference in methods which in this case is the claim about new method of culturing cheese reduces aging time. So, it means that mean aging time of old method will be greater than mean aging time of new method. So, the alternative hypothesis can be written as

Alternative hypothesis: The new method of culturing cheese reduces mean aging time as compared to old method of culturing cheese

Or symbolically it can be written as

Ha:μ1>μ2

whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.

Describe the shape of the given histogram.

Answers

Uniform?
Pretty sure its not a unimodal/left skewed and right skewed as theres no sudden drop and the frequency are all similar

The given histogram is uniform histogram.

Since we know that,

A histogram is a graphical depiction of data distribution in statistics. The histogram is represented by a series of neighboring rectangles, with each bar representing a different type of data.

Statistics is a branch of mathematics that is used in a variety of areas. When numbers are repeated in statistical data, this repetition is known as Frequency, and it may be put down in the form of a table, which is known as a frequency distribution.

A Frequency distribution may be represented graphically using several types of graphs, one of which is a Histogram.

Based on the frequency distribution of the data, the histogram may be categorised into distinct categories. Normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distribution, heart cut distribution, and so on are all examples of distributions. These many sorts of distributions can be represented by the histogram.

A histogram can be of several types:

Histogram that is uniform

Histogram with symmetry

Histogram with two modes

Probability distribution histogram

A uniform distribution demonstrates that the number of classes is too small, with the same amount of components in each class. It might involve a distribution with many peaks.

Since we can see in the given histogram,

The average frequency is 5

And almost all the bars are ending at 5

Hence,

This histogram is uniform histogram.

What is Algebra?

Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.

We have to find an algebraic expression which represents the phrase "seven more than half of a number".

Consider a number x,

half of x = (x/2)

seven more than half = (x/2) + 7

Hence, seven more than half of a number is (x/2) + 7.

A sphere has a radius of 15 inches. What is the volume of the sphere, in cubic inches? (Use 3.14 as an approximation of pi.)

Answers

Based on the calculations, the volume of this sphere is equal to 14,130 cubic inches.

Given the following data:

Radius of sphere = 15 inches.

[tex]\pi =3.14[/tex]

How to calculate the volume of a sphere.

Mathematically, the volume of a sphere is given by this formula:

[tex]V=\frac{4}{3} \pi r^3[/tex]

Where:

V is the volume.r is the radius.

Substituting the given parameters into the formula, we have;

[tex]V=\frac{4}{3} \times 3.14 \times 15^3\\\\V=\frac{4}{3} \times 3.14 \times 3375\\\\V=\frac{42390}{3}[/tex]
