Monica received $ 7 amount of money for each pair of sneakers she sold.

We are given that:

Remaining amount with Monica = $ 8

She spent on earing = $ 13

The total amount she had = $ 13 + $ 8

The total amount she had = $ 21

Now, she sold 3 pairs of sneakers and gained $ 21

So, the price of each snicker will be calculated by using division.

So, we get that:

Monica receive for each pair of sneakers = $ 21 / 3 = $ 7

Therefore, Monica received $ 7 amount of money for each pair of sneakers she sold.

The modal class of the given frequency distribution table is found as: 0-10.

The mean found for the frequencies of swimming pool  is 36.5.

The given grouped class interval is-

Time(min):                 0-10    11-20    21-30    31-40

Number of people:   68     42       20          16

Modal class: The modal class is indeed the class interval within such a set of data that has the greatest number of data points, also known as the highest frequency.

Thus, from the given frequencies, the maximum frequency that is 68 occurred for the class of 0-10.

Thus, the modal class is: 0 - 10.

For the calculation of mean;

mean = sum of all frequencies/number of frequencies

mean = (68 + 42 + 20 + 16)4

mean  = 146/4

mean = 36.5

Therefore, the mean of the frequency for the swimming pool is 36.5.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equal sign. The relations are: x+3, 3x², 3ˣ

An equation is a formula that expresses the equality of two expressions, by connecting them with the equal sign.

Finding the relations:

Relationship 1:

The y-values have a common difference of 1, so the relationship is linear with as slope of 1. The only matching choice is (x+3), which matches the values of y1.

Relationship 2:

The y-values have differences that increase with a common difference. They are (3-0) = 3, (12-3) = 9, (27-12) = 15, (48 -27) = 21. The second differences are (9-3) = 6, (15-9) = 6, and so on with all second differences being 6. This tells you that a second-degree polynomial can model this sequence. The only matching choice is 3x² which matches the values of y².

Relationship 3:

The y-values have increasing differences that also have increasing differences. The values have a common ratio of 3, indicating an exponential function will model this sequence. The only matching choice is (3ˣ), which matches the values of y³.

Therefore the relations are: x+3, 3x² and 3ˣ

A graph of the given ordered pair (-5 3 1/2) has been plotted as shown in the image attached below.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

An ordered pair can be defined as a pair of two elements that are typically written in a fixed order within parentheses as (x, y), which represents the x-axis (abscissa) and the y-axis (ordinate) on a coordinate plane.

In conclusion, the point (-5) would be plotted on the x-axis (abscissa) while point (3 1/2) would be plotted on the y-axis (ordinate) of a coordinate plane as shown in the image attached below.

The point slope form of the given slope intercept form is:

y ₋ 9 = ₋1/3 (x ₋ 0)

Given, we have the slope intercept form as :

y = ₋1/3x ₊ 9

To convert the given form into point slope form we first need to determine the slope and the point.

A straight line is represented as a point on the line and its slope in point slope form. That means using the point slope form, one may find the equation of a line passing through the points (x ₁, y ₁) and having a slope of "m".

from the given equation y = ₋1/3x ₊ 9

the above equation is in the form of: y = mx ₊ b

slope (m) = ₋1/3

y intercept (b) = 9

x intercept = 0

Therefore, the points are: (0,9) = (x₁ , y₁)

hence the point slope form is:

y - y₁ = m(x ₋ x₁)

y ₋ 9 = -1/3(x ₋ 0)

hence we get the required point slope form.

The driver that is predict to win the next drag race will be A. Driver A had a mean race time of 3.81 seconds and a standard deviation of 0.21 seconds.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.

Given that we are aware that standard deviations indicate variability in a data collection, the variability is greater the higher the standard deviations.

In this case, A has the higher standard deviation. Therefore, the driver that is predict to win the next drag race will be Driver A had a mean race time of 3.81 seconds and a standard deviation of 0.21 seconds.

The required answers are,

The greatest number of binders Eula can buy is 5.

The greatest number of notebooks Eula can buy is 10.

If 7 notebooks are ordered, one binder may also be bought, costing $2 more for Eula.

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now the given inequality is,

4x + 2y ≤ 20

here x is the number of binders and y is number of notebooks.

Cost of 1 binder = $4

Cost of 1 notebook = $2

Now for maximum number of binders put y = 0 in the given inequality we get,

4x + 2*0 ≤ 20

Solving we get,

4x  ≤ 20

Dividing both the side by 4 we get,

x ≤ 5

Thus, Eula is permitted to acquire 5 binders in the absence of notebook purchases.

Now for maximum number of notebooks,

Putting x = 0 in the given inequality we get,

4*0 + 2y ≤ 20

Solving we get,

2y  ≤ 20

Dividing both the side by 2 we get,

y ≤ 10

Thus, Eula is permitted to purchase 10 notebooks if no binders are purchased.

Now if Eula buys 7 notebooks, putting y = 7 in the given inequality we get,

4x + 2*7 ≤ 20

Solving we get,

4x + 14 ≤ 20

Subtracting both the side by 14 we get,

4x ≤ 6

Dividing both the side by 4 we get,

x ≤ 3/2

⇒ x ≤ 1.5 ≈ 2

Thus, If 7 notebooks are ordered, one binder may also be bought, costing $2 more for Eula.

Hence,If 7 notebooks are ordered, one binder may also be bought, costing $2 more for Eula.

Thus, the required answers are,

The greatest number of binders Eula can buy is 5.

Answer: Bikes were ordered as part of new order order is = 80 bikes

scooters were ordered as part of new order order is = 32 scooters.

Step-by-step explanation:

Given data,

A sporting goods store ordered new bikes and scooters.

For every 3 bikes ordered, 4 scooters were ordered.

Then, The ratio of the bike and scooter is equal to = 3:4

where,

bike ratio is 3

scooter ratio is 4

Then 48 bikes

original order = 64 scooter

                       = 64/4

                       = 16 scooters

However, bike is more popular than scooter.

So,

they changed it into new ratio = 5:2

where,

5 is equals to bikes ratio

and 2 is equal to scooter ratio.

Then,

5(original order) = 5(16)

                           = 80 bikes

2(original order) = 2(16)

                           = 32 scooters.

Therefore,

bikes were ordered as part of new order order is = 80 bikes

scooters were ordered as part of new order order is = 32 scooters.
