The numbers in the equations are -4 and -26

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

Let the numbers be x and y

A system of linear equations is a collection of at least two linear equations. So, we have the following linear equations

y = 5x - 6

x - y = 22

Substitute y = 5x - 6 in x - y = 22

x -5x + 6 = 22

Evaluate the like terms

-4x = 16

Divide both sides by -4

x = -4

Substitute x = -4 in y = 5x - 6

y = 5 * -4 - 6

Evaluate

y = -26

Hence, the numbers are -4 and -26

The term that best represents the intersection of two pages of an open book is point.

A third item made up of everything that is simultaneously contained in all of the other things is called an intersection of two or more objects in mathematics. In Euclidean geometry, for instance, the intersection of two lines in a plane that are not parallel is where they come together. More broadly, the set of elements that are a part of all of the sets is what is meant by the intersection of sets in set theory. The items being considered do not need to be in a shared space, unlike the Euclidean concept.

A point is the most frequent shape for an intersection in plane geometry, while there are other shapes that can be used as well. An intersection is an item of lesser dimension that is incident to each in incidence geometry, which is typically applied to flats.

The numbers given in scientific notation will be arranged from least to greatest as: 7.6×10⁻²⁰, 5.5×10⁻¹¹, 2.4×10², 8.9×10², 9.2×10⁴, 7.6×10²⁰.

Scientific notation of numbers may be defined as the way of representation of bigger numbers into powers of 10. This helps in reducing space as well as it helps in conveniently solving the problem. For example, scientific notation of 92000 may be written as 9.2×10⁴.

Here in the number 7.6×10⁻²⁰ the power of 10 is maximum but with a negative value so it is the least number. Then comes the number 5.5×10⁻¹¹ as its power are also negative but greater than the previous number. Similarly using the above logic, the other numbers will be placed, and the greatest number would be 7.6×10²⁰ as it has the maximum power of 10 that too with a positive sign.

Based on the 1.5 × IQR rule for outliers, there is no evidence to support the student's claim because there is only one outlier at 58 minutes.

An outlier is also referred to as anomalous data and it can be defined as a numerical value that is either unusually too small or large (big) in comparison with the overall pattern of the numerical values contained in a data set.

IQR is an abbreviation for interquartile range and it can be defined as a measure of the middle 50% of data values when they are ordered from lowest to highest.

Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

Based on the given data set, the following interquartile ranges was calculated by using Excel:

Q₃ = 31.5

Q₁ = 20.5

Now, the interquartile range (IQR) is given by:

IQR = Q₃ - Q₁

IQR = 31.5 - 20.5

IQR = 11

Based on the 1.5 × IQR rule for outliers, we have:

1.5 × IQR = 1.5 × 11 = 16.5

Therefore, our fences will be 16.5 points below Q₁ and 16.5 points above Q₃:

Lower fence = 20.5 - 16.5 = 4.5

Upper fence = 4.5 + 31.5 = 36.

In conclusion, we can reasonably infer and logically deduce that there is no evidence to support the student's claim because there is only one outlier at 58 minutes.

The inverse of the given function,f(t) = 100 . 2^(t/4) is 4 * log2(x/100).

What is the inverse of a function?

An inverse of a function f(x), is defined as another function that undoes the operations performed on the function. It is denoted by f^(-1).

Calculation of the inverse of a function

We are given a function,

f(t) = 100 . 2^(t/4)

Let us assume that f^(-1) represents the inverse of a function

Replacing f(t) with y, we get,

y = 100 . 2^(t/4)

Now, replace further t with y and y with x

x = 100 . 2^(y/4)

Rearranging, we have,

2^(y/4) = x / 100

Taking log both sides, we get,

(y/4) log 2 = log (x/100)

y/4 = log2(x/100)

y = 4 * log2(x/100)

Further, replace x with t and y with f^(-1), i.e.

f^(-1) = 4 * log2(t/100)

Hence, the inverse of the given function, f(t) = 100 . 2^(t/4) is 4 * log2(x/100).

The 5 number are 25, 25, 35, 45 and 70 that has the mean of 40 and a median and deviation of 35 and a mode of 25.

Mean:

Mean is the sum of all observations divided by the number of observations.

Median:

Median defines the value of the middlemost observation, obtained after arranging the data in ascending or descending order.

Mode:

The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.

Given,

Mean = 40

Median = 35

Mode = 25

We know that the mean value is  is the sum of all observations divided by the number of observations.

So, Let us consider v,w,x,y,z are the five numbers.

So it can be written as,

[tex]Mean=\frac{v+w+x+y+z}{n}[/tex]

We know that,

Mean = 40 and n = 5.

Then,

[tex]40=\frac{v+w+x+y+z}{5}[/tex]

Therefore,

=> v + w + x + y + z = 40 x 5

=> v + w + x + y + z = 200 --------------------------(1)

Here we know that the Median is 35.

The median in equation (1) is x,

So x = 35

And the mode is 25, we know that definition of mode so let us consider it will occurs at least twice,

So, the values of v = 25 and u = 25

Now apply the values on the equation,

=> 25 + 25 + 35 + y + z = 200

=> 85 + y + z = 200

=> y + z = 200 - 85

=> y + z = 115

So, here we have to take the combinations that gives the value of 115 and the values must be greater than 35.

So, the values are 45 and 70.

Therefore, the five numbers are 25, 25, 35, 45 and 70.

Identity of the square of a sum of two numbers:

Given equation:

We can see one of the numbers is y, and the second one is 15 as twice the product is 30y.

Add 15² = 225 to both sides to complete the square, then solve it:

Answers:

y = ± 221.47, y = -0.24, y = -29.76

Step-by-step explanation:

y^2 + 30y = -7

Move -7 over to the other side

y^2 + 30y +7 = 0

This takes form of a quadratic equation of ax^2 + bx + c = 0, where y = x

Quadratic formula is x = (-b ± (sqrtb^2 - 4ac)/2a and replace everything so it's y = (-30 ± (sqrt30^2 - 4*1*7)/2*1. Once solved, the answer choices are y = ± 221.47, y = -0.24, or -29.76.

The final step to be performed in the mathematical expression, (Σx)2 is square the sum of the scores

Sum of squares is a statistical method for calculating the dispersion of data points in regression analysis. By deviating the least from the data, the sum of squares can be used to identify the function that fits the data the best. The purpose of a regression analysis is to assess how well a data series can be fitted to a function that could provide insight into the process by which the data series was created. In the world of finance, the sum of squares can be used to calculate the variation in asset values.

A statistical measure of departure from the mean is the sum of squares. Variation is another name for it. The squared differences of each data point are added together to calculate it. The sum of squares is calculated by squaring the separation between each data point and the line of best fit, then adding the results. The line of greatest fit will reduce this value to the minimum.

We first find the sum, and then square the sum.

ΣX = 1 + 0 + 2 + 4 = 7

So,  ΣX + 1 = 8

Mean = ( 4+6+14 )/3 = 8

Mean =  ΣX*f /  Σf = (5*2 + 4*1 + 3*3 + 2*2 + 1*2) / (2+1+3+2+2) = 29/10

Subtract 3 points from the score X=3

Changing the lowest score to a lower one will increase the range.
