Carlos took 8 minutes to complete 5 3/4 laps all around school track.

Now, to answer the question

5 3/4 laps = 23/4 laps

= (23/4)/8

Simplifying the equation;

=23/4 × 1/8

=23/32

Therefore, Carlos will take 23/32 laps per minute to running on school track.

Using simple interest, Alice need to invest 25000 now in order to get 12 000 saved in 4 years' time at 12% simple interest.

The daily interest rate, the principle, and the number of days between payments are multiplied to determine simple interest. Consumers who pay their loans off on time or ahead of schedule each month benefit from simple interest. Simple interest loans are frequently used for auto loans and short-term personal loans.

Given,

simple interest = 12000

rate of interest = 12%

time  = 4 years

Simple interest = P × R × T / 100

12000 = P × 12 × 4 / 100

P = 25000

The numerical length of RS is 16.

Given, Point R is on line segment QS.

A line segment in geometry has two different points on it that define its boundaries. A stretch of a line that connects two locations is frequently referred to as a line segment. A line has no ends and can continue indefinitely in either direction, which is how it differs from a line segment.

QR = 4 , QS = 4x and RS  = 5x ₋ 9

we know that,  QS ₊ RS = QR

⇒ RS = QR ₋ QS

⇒ 5x ₋ 9 = 4x ₋ 4

unknown items move to the left of the equal sign and known items move to the right of the equal sign.

5x ₋ 4x = 9 ₋ 4

x = 5

therefore, RS = 5x ₋ 9

= 5(5) ₋ 9

= 25 ₋ 9

= 16

hence we get the length of RS as 16.

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 blue graph is a translation of 2 units to the left and 1 unit up of the parent function, thus, the equation is:

g(x) =  |x + 2| + 1

We know that the red graph is an absolute value function, so we have:

f(x) = |x|

And we want to find the equation of the blue absolute value function, which is a translation of the above one.

Notice that the vertex of the blue one is at (-2, 1), so we have a translation of 2 units to the left and one unit up, it is just written as:

y = |x + 2| + 1

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.

A stem-and-leaf plot is a table that is used to represent a dataset. A stem-and-leaf plot is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf.

The stem is the first number in the digit while the leaf is the last number. For example in the number 25, 2 would be the stem and 5 would be the leaf. A stem-and-leaf plot usually arranges the dataset in ascending order.

An advantage of a stem-and-leaf plot is that it contains all the data in the dataset. A disadvantage of the stem-and-leaf plot is that it can only be used for a small dataset.

The notion of inventory includes both raw materials utilized in production and finished commodities offered for sale. Inventory is one of a company's most significant assets because it is one of the primary sources of revenue generation and, as a result, a source of profits again for the company's shareholders. Inventory is divided into three categories: finished goods, work-in-progress, plus raw materials. It is classified as a current asset on a corporation's balance sheet.

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 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 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.

It is true that the two graphs of g(x) = sin (x + 2π) and f(x) = sin x are identical.

The sine function is a periodic function, which means that the value of the sine function repeats itself after a regular interval. This regular interval is called the period. The period for a sine function is 2π radians. This means that the value of the sine function will be same for any two points separated by 2π radians.

If x = 0, then sin (x) = sin (0) = 0 and sin (x + 2π) = sin (0 + 2π) = sin (2π) = 0

If x = π/2, then sin (x) = sin (π/2) = 1 and sin (x + 2π) = sin (π/2 + 2π) = sin (5π/2) = 1

Thus, it can be seen that the graph of sin (x + 2π) replicates the graph of sin (x) exactly after one period of the sine function.

Thus, we conclude that it is true that the two graphs of g(x) and f(x) are identical.
