Answer:

equation: 41+4x=45.80

answer: x=1.20

Step-by-step explanation:

The equation is $45.80 = $41 + ($4 × x) which can be used to determine the number of gigabytes of data Nathaniel can use while staying within his budget. And Nathaniel can use up to 1.2 gigabytes of data while staying within his budget of $45.80 per month.

Let's denote the number of gigabytes of data Nathaniel can use as x.

Then the equation representing his cell phone bill can be set up as:

Total cost = Flat cost + (Cost per gigabyte × Number of gigabytes)

$45.80 = $41 + ($4 × x)

Now, we can solve for x:

$4 × x = $45.80 - $41

$4 × x = $4.80

x = $4.80 / $4

x = 1.2

So, Nathaniel can use up to 1.2 gigabytes of data while staying within his budget of $45.80 per month.

The total cost of pizza and drinks, is an illustration of a linear function.

The model that represents the situation is: \(\mathbf{10 + 3d = 19}\)

The given parameters are:

\(\mathbf{Total =19}\)

\(\mathbf{1\ pizza =10}\)

\(\mathbf{1\ drink =d}\)

The cost of 3 drinks will be 3d

The total cost would then be:

\(\mathbf{Total = 10 + 3d}\)

Substitute 19 for Total

\(\mathbf{10 + 3d = 19}\)

Rewrite the above equation as:

\(\mathbf{3d + 10 = 19}\)

Hence, the model that represents the situation is: \(\mathbf{10 + 3d = 19}\)

Angle A and B are shown to be the same which means the 2 sides are the same. Using the 2 sides solve for x.

2x -24 = x-2

Add 24 to both sides

2x = x + 22

Subtract x from both sides:

X = 22

Bc = x , so BC = 22

If a case-control study were conducted to investigate the relationship between an exposure and a rare disease like neck cancer, the most likely relative measure that would be estimated is the odds ratio.

This is because the prevalence of neck cancer in the general population is low, which means that the incidence rate is also low. As a result, it is difficult to calculate the relative risk directly in a case-control study. Instead, the odds ratio is used as a measure of association between the exposure and the disease outcome.

The odds ratio is calculated by comparing the odds of exposure in cases to the odds of exposure in controls. The odds ratio can provide an estimate of the strength and direction of the association between the exposure and the disease outcome in the population being studied.

This represents the direction and degree of rotation utilised to make the image, which is 90 degrees anticlockwise.

When an item or form is rotated about a fixed point, generally the origin or a specified point in the plane, the amount of rotation that takes place is referred to as the degree of rotation. Angles are measured in degrees, where one full rotation equals 360 degrees. The amount of angle shift, expressed in degrees, that occurs when an item or shape is rotated is known as the degree of rotation. A shape has been turned a quarter of a full rotation anticlockwise, for instance, if it is rotated 90 degrees in that direction. Similar to this, a form has completed one-half of a full rotation if it is rotated 180 degrees.

given

The graph suggests that the image was rotated 90 degrees anticlockwise and in the other manner to make.

Compare the figure's initial placement (the grey triangle) to its final placement to see this (the red triangle).

One of the vertices on the grey triangle is pointing upward, and the other two are pointing to the right and left.

The red triangle's up-pointing vertex remains after the transformation, but the other two vertices now point down and up-left, respectively.

This represents the direction and degree of rotation utilised to make the image, which is 90 degrees anticlockwise.

If you make a Type I error in this case, you will incorrectly reject the null hypothesis and conclude that the water is safe to drink. As a result, you may end up drinking contaminated water, which could lead to illness or other health problems.

In hypothesis testing, a Type I error occurs when you reject the null hypothesis even though it is true. In the given scenario, the null hypothesis is that the water in the stream is not safe to drink, and the alternative hypothesis is that it is safe.

If you make a Type I error, you would incorrectly conclude that the water is safe to drink, even though it may be contaminated with harmful bacteria or chemicals.

The consequences of drinking contaminated water can be severe, ranging from mild stomach upset to more serious health problems like diarrhea, vomiting, and even death.

Therefore, it is crucial to conduct thorough testing and analysis of the water to ensure its safety before consuming it.

Answer:

A. 18x - 3y = 6

Step-by-step explanation:

By taking 3 common from the terms 18x and 3y we get,

3 (6x-3y) = 6

or, 6x - y = 6/3

or, 6x - y = 2

And,

The equation becomes,

y = 6x - 2

The equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

By taking 3 commons from the terms 18x and 3y we get,

3 (6x-3y) = 6

6x - y = 6/3

6x - y = 2

The equation becomes,

y = 6x - 2

Therefore, the equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

What is conditional statement?

A conditional statement is a type of logical statement that has two parts: a hypothesis and a conclusion. The hypothesis is the "if" part of the statement, and the conclusion is the "then" part. The conditional statement asserts that if the hypothesis is true, then the conclusion must also be true.

The given statement is True.

This is an example of a proof by conditional statement. To prove a conditional statement of the form "If A, then B," you assume A and use deductive reasoning to show that B logically follows. In this case, you assume the antecedent (c ⊃ (i ≡ z)) and attempt to prove the consequent (f) within the scope of that assumption. If you are successful, then you have shown that the conditional statement is true.

Mean = 1.8 in

Step-by-step explanation:

The Median is the middle value when all data values are placed in order of size.

Ordered data values:  0, 0, 0, 1, 1, 1, 2, 3, 4, 6

As there is an even number of data values, the middle value is the mean of the middle two data values.  Therefore, the Median = 1 in

The Mean is the sum of all data values divided by the total number of data values.

\(\implies \textsf{Mean}=\dfrac{0+0+0+1+1+1+2+3+4+6}{10}=1.8\)

Therefore, the Mean = 1.8 in

The Median is a better measure of central tendency when the data includes outliers (data values that are far away from the majority), as it is not affected by those outliers.  As there does not appear to be any outliers in this data set, the mean can be used to best describe the center of the data.

Therefore, the Mean = 1.8 in

The two equivalent ratios of 15 / 60 are 30/120 and  45 / 180.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

The given fraction or ratio is 15 / 60. The equivalent ratio to the 15 / 60 will be written as:-

15 / 60 = 15 x 2 / 60 x 2

15 / 60 = 30 / 120

Multiply the numerator and the denominator by the same number.

15 / 60 = 15 x 3 / 60 x 3

15 / 60 = 45 / 180

Therefore, the two equivalent ratios of 15 / 60 are 30/120 and  45 / 180.
