Which ones better? How much more r u saving?

Answer:

C

Step-by-step explanation:

First, let us clarify what (11, 0) represent

(x, y) ---> (11, 0)

The values are as followed:

x = 11

y = 0

If the problem states that x is the number of days after the promotion started, then it will be 11 days.

When we assert that it has been 11 days, we rule answers A and D.

If the problem states that y is the number of free coffee samples that remain after 11 days (because x is included in this statement), then it will be 0 samples.

Therefore, the answer will be C. After 11 days of the promotion, there will be 0 samples that are left.

The steps of finding mean and standard deviation of a simple random sample are given below.

What is standard deviation and mean?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

There are various mean types in mathematics, particularly in statistics. Each mean serves to summarize a specific set of data, frequently to help determine the overall significance of a specific data set.

The steps of finding mean and standard deviation of a simple random sample are:

Divide the population standard deviation (σX) by the square root of the sample size (n) to get the standard deviation of the sample mean (σX):  = σ/n.

How to determine sample means

Add up the examples' components. You must first count the number of sample items in each data set and then add up all of the sample items. ...

Sum divided by the quantity of samples.

The outcome is the mean.

3*(4x - 3) = 63                         Divide both sides by 3

4x - 3 = 63/3

4x - 3 = 21                                Add 3 to both sides

4x = 21 + 3

4x = 24                                    Divide by 4 on both sides

4x/4 = 24/4

x = 6

Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)

The dimension of the fountain will be 20ft x 20ft x 2.5ft. Let the width of the fountain be x ft. The length of the fountain will be x ft as well. The height of the fountain will be 2.5 ft.

Therefore, the volume of the fountain will be:V = (length) × (width) × (height)

V = (x) × (x) × (2.5)

V = 2.5x²

Now, let us calculate the area of the sidewalk. The area of the sidewalk is a rectangular region with the dimensions (length + 2) × (width + 2). This is because there are two additional feet on both sides of the length and width of the fountain. Therefore, we can represent the area of the sidewalk as follows: A = (length + 2) × (width + 2)

A = (x + 2) × (x + 2)

A = (x + 2)²

Now, since the total area of the fountain and sidewalk is 700ft², we can write an equation as follows: 2.5x² + (x + 2)² = 700 Expanding and solving the quadratic equation

we get,x² + 4x - 348 = 0

(x + 19)(x - 15) = 0

Since the width of the fountain cannot be negative, we will only consider the positive root, x = 15 feet.

Therefore, the dimensions of the fountain will be 20ft x 20ft x 2.5ft.

The price of a rake would be $10 if the price of a shovel is $30, according to the given relationship.

A situation can be used to quantify the connection between the costs of a rake, denoted by "r," and digging tools, denoted by "s." According to the information that was provided, the price of a rake is one third (3/3) higher than the price of a shovel.

This genuinely plans that in case the expense of a digging device is "s," the expense of a rake would be 33% of "s," which can be made as (1/3) * s. Thusly, the condition that tends to the association between the expense of a rake and the expense of a digging device is:

The cost of a rake is simply equivalent to one third of the cost of a shovel, according to this equation. Using this equation, we can determine how much a rake costs if we know how much a shovel costs. For example, expecting that a digging tool costs $30, the cost of a rake would be:

Because r = (1/3) * s = (1/3) * $30 = $10, the given relationship says that a rake would cost $10 if a shovel cost $30.

A subset of a population selected to represent the population is a sample.

A sample is a subset of a population that is selected to represent the larger population as a whole. It is important to select a representative sample so that the results of the analysis are accurate and reliable.

A population can be defined as a group of individuals, objects, or subjects that share common observable characteristics or traits. A population is a group of things that share something in common, and it can be any size.

A sample is a smaller group of individuals, objects, or subjects that are taken from the population to perform research or statistical analysis. Samples are typically used in research to estimate what is happening in the population as a whole.

A subset is a subset of a larger group.

In other words, it is a smaller set that is part of a larger set. A subset can contain any number of elements or members, and it can be of any size.

A sequence of transformation that would move ΔABC onto ΔDEF is: D. a dilation by a scale factor of 1/2, centered at the origin, followed by a 90° clockwise rotation about the origin.

In Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

In this scenario an exercise, we would dilate the coordinates of the pre-image by applying a scale factor of 1/2 that is centered at the origin as follows:

Ordered pair B (-4, 2) → Ordered pair B' (-4 × 1/2, 2 × 1/2) = Ordered pair B' (-2, 1).

In Mathematics and Geometry, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction;

(x, y)                               →            (y, -x)

We can say that the cartesian product is not commutative for r and s because r × s ≠ s × r.

What is meant by cartesian product?

The set of all ordered pairs of the sets is the cartesian product of two or more sets. Set theory is where it is used the most frequently. A pair of items that are an ordered pair have one element assigned first and the other element assigned second. The set of all ordered pairs (a, b) with the first element from C and the second element from D is the cartesian product C × D,  if C and D are two non-empty sets. We denote the cartesian product between two sets using the same multiplication sign as we do for the other product operations, which is ×.

Given:

r = {1,2,3}

s = {3,4}

We first find the cartesian product r×s

In this, the resulting ordered pair will have x values from r.

The cartesian product = {(1,3) , (1,4) , (2,3), (2,4), (3,3), (3,4)}

Now we find the cartesian product  s×r

The cartesian product = {(3,1) , (3,2) , (3,3), (4,1), (4,2), (4,3)}

We can see that both r×s and s×r do not have the same ordered pairs.

Therefore we can say that the cartesian product is not commutative for r and s because r × s ≠ s × r.

Answer:

Length = 12cm

Step-by-step explanation:

The dimensions of the recatngle is:

- width → x

and

- length → x+7

The area of a rectangle follows the formula: length*width

Meaning: x * (x + 7) = 60

Expand that: x^2 + 7x = 60

Rearragne the equation and factorise it

(x-5)(x+12) = 0

The width cannot be a negative value, so the answer must be 5.

Remember that x was the width and the length is the width add the 7.

So the length is 12 cm.

Option D. The triangle inequality theorem is verified by by showing that a triangle cannot be formed when the sum of the lengths of two sides is less than the length of the third side.

From the given picture we can see the length of the sides. These are 7, 4 and 15.

The length of the two sides cannot join due to the fact that they are less than 15.

4 + 7 < 15
