The distances between each pair of points are as follows:

1. (1, -4.6) and (3, -7): 3.12 (rounded to two decimal places)

2. (-6, -5) and (2, 0): √89 (exact value)

M = (-12, -1) and M = (4, 0): √257 (exact value)

4. (0, -8) and (3, 2): √109 (exact value)

3. (-1, 4) and (1, -1): √29 (exact value)

We may use the distance formula to calculate the separation between each pair of points:

d = √((x₂ - x₁)² + (y₂ - y₁)²),

where the two points' coordinates are represented by (x1, y1) and (x2, y2), respectively.

Let's determine the separation between each pair of points:

1. (1, -4.6) and (3, -7):

d = √((3 - 1)² + (-7 - (-4.6))²)

= √(2² + (-2.4)²)

= √(4 + 5.76)

= √9.76

= 3.12 (rounded to two decimal places)

2. (-6, -5) and (2, 0):

d = √((2 - (-6))² + (0 - (-5))²)

= √(8² + 5²)

= √(64 + 25)

= √89 (exact value)

M = (-12, -1) and M = (4, 0):

d = √((4 - (-12))² + (0 - (-1))²)

= √(16² + 1²)

= √(256 + 1)

= √257 (exact value)

4. (0, -8) and (3, 2):

d = √((3 - 0)² + (2 - (-8))²)

= √(3² + 10²)

= √(9 + 100)

= √109 (exact value)

3. (-1, 4) and (1, -1):

d = √((1 - (-1))² + (-1 - 4)²)

= √(2² + (-5)²)

= √(4 + 25)

= √29 (exact value)

Step-by-step explanation:

pls stop this madness

7 . 3 - 3 . 3

= 21 - 9

= 12

Just substitute you y = 3 into the equation

Answer:

The correct answer is 12.

Step-by-step explanation:

To solve this problem, we must plug in 3 for each occurrence of y in the expression because we are given that y = 3.  In this case, we will get the following:

7y - 3y

7(3) - 3(3)

To evaluate, we must simplify this expression.  Due to the order of operations, we should compute the multiplication first.  7*3 = 21 and 3*3=9, so we can plug in these values into our expression.

21 - 9

Now, we can perform the subtraction.

21-9=12

Therefore, the correct answer is 12.

True, to calculate the average of numeric values in the list, the first step is to get the total of values in the list.

Steps to calculate the Average:

Let’s assume there are 4 numbers having values of 2,8,22,48 respectively.

To find the average we first have to take the total of all values.

2+8+22+48=80.

Our next step will be to divide this total by the number we have in our question i.e., 4.

so, our average will be 80/4= 20.

So, 20 will be our average.

So yes, it is true that to calculate the average of numeric values in the list, the first step is to get the total of all values in the list.

Answer:

Debra needs 14 cups of fertilizer.

Step-by-step explanation:

Step 1:  Find the area of Debra's rectangular vegetable garden:

Before we can determine how many cups of fertilizer she needs, we'll need to know the area of Debra's garden.  This will tell us how many square yards her garden covers.  The formula for the area of a rectangle is given by:

A = lw, where

Thus, we can plug in 9(1)/(3) for l and 12 for w in the rectangle area formula to find A, the area of Debra's garden in square yards:

A = 9(1)/(3) * 12

A = 112

Thus, the area of Debra's garden is 112 square yards.

Step 2:  Create a proportion to find x, the number of cups of fertilizers she needs:

We're told that cups of fertilizer with water are proportional to the square yards of Debra's garden.  Thus, we can create a proportion to find x, the number of cups of fertilizer she needs:

(1)/(8) cups / 1 square yard = x cups / 112 square yards

1/8 = x/112

14 = x

Thus, Debra needs 14 cups of fertilizer since her garden covers 112 square yards.

The correct answer is option D. We can be 95% confident that the sample proportion is captured by the confidence interval.

The margin of error of plus or minus three percentage points at a 95% confidence level means that the true proportion of people who jog regularly in the population is estimated to be between 15% and 21%. We can be 95% confident that the true proportion of people who jog regularly falls within this interval.

Therefore, option B is correct. Option A is incorrect because it implies that the margin of error always holds true for any sample size, which is not the case. Option C is incorrect because it presents a range of values for the population, not for the estimate. Option E is incorrect because it refers to the proportion of samples that would find the same sample proportion, not the range of values within which the true proportion lies.

The number of different values obtained by inserting parentheses into the expression "5-1-1-1-1-1" is 10.

To find out the number of different values that can be obtained by inserting parentheses into the given expression, we can use a counting technique called Catalan numbers.

The expression 5−1−1−1−1−1 has 5 subtraction operations. To insert parentheses, we can choose any two subtraction operations and group the terms between them. Therefore, the number of different ways to insert parentheses is equal to the number of ways to choose 2 positions out of the 5 positions for the subtraction operations.

This can be calculated using the formula for combinations: nCk = n! / (k!(n-k)!), where n is the total number of positions and k is the number of positions to choose.

In this case, n = 5 and k = 2. Plugging in the values, we have:

5C2 = 5! / (2!(5-2)!) = 5! / (2!3!) = (5*4*3*2*1) / ((2*1)(3*2*1)) = 10

Therefore, there are 10 different values that can be obtained by inserting parentheses into the given expression.

The most appropriate units to describe the cost of the sandbox would indeed be dollars.

When describing the cost of an item or service, it is essential to use the unit that represents the currency being used for the transaction. In this case, the total cost of the sand for the school's sandbox is given in dollars. To maintain consistency and clarity, it is best to express the cost in the same unit it was provided.

Using dollars as the unit for the cost allows for clear communication and understanding among individuals involved in the transaction or discussion. Dollars are widely recognized as the standard unit of currency in many countries, including the United States, where the dollar sign ($) is commonly used to denote monetary values.

Using meters, the unit for measuring the dimensions of the sandbox, to describe the cost would be inappropriate and could lead to confusion or misunderstandings. Mixing units can cause ambiguity and hinder effective communication.

Therefore, it is most appropriate to describe the cost of the sand in dollars, aligning with the unit of currency provided and commonly used in financial transactions. This ensures clarity and facilitates accurate comprehension of the cost associated with the sand purchase for the school's sandbox.

The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.

The two most important parts of a vehicle in preventing traction loss are the tires and the traction control system.

Tires: Tires are the primary point of contact between the vehicle and the road surface. The quality and condition of the tires greatly influence traction. Tires with good tread depth and appropriate tread pattern are essential for maintaining grip on the road. Tread depth helps to channel water, snow, or debris away from the tire, preventing hydroplaning or loss of traction. Additionally, tire pressure should be properly maintained to ensure even contact with the road. Choosing tires suitable for the specific driving conditions, such as all-season, winter, or performance tires, is crucial for optimal traction and handling.

Traction Control System: The traction control system is a vehicle safety feature that helps prevent the wheels from slipping or spinning on low-traction surfaces. It uses various sensors to monitor the speed and rotation of the wheels. If the system detects a loss of traction, it will automatically reduce engine power and apply braking force to the wheels that are slipping. By modulating power delivery and braking, the traction control system helps maintain traction and prevent wheel spin, especially in challenging conditions like slippery roads or during quick acceleration.

The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.

Answer:

19

Step-by-step explanation:

200−181 = 19

There are 19 whole numbers between 181 and 200.

From the graph of miles driven and pricing, it can be observed that for 200 miles option A price is $100 and option B price is $70.

So option A cost more than option B.

Determine the difference between $100 and $70 to obtain how much option A cost more than option B.

So option A cost $30 more than option B.

From the graph, it can be observed that lines of option A and option B intersect each other at (50,40). So option A and option B cost same for 50 miles.

Volume of a cylindrical silo is given by,

\(V=\pi r^{2}h\)

Here, \(V=\) Volume of the silo

\(r=\) Radius of the cylindrical silo

\(h=\) Hight of the silo

And height of the silo is defined by the function,

\(h(r)=3.5r\)

Option (1)

To get the volume of \(100\) cubic feet, radius must be \(2\) feet.

Height of the silo can be derived from the function,

\(h(2)=3.5(2)\)

      \(=7\) feet

Therefore, volume of the silo = \(\pi r^{2} h\)

                                                 = \(\pi (2)^2(7)\)

                                                 = \(28\pi\)

                                                 = \(87.96\) feet³

Since, \(87.96<100\) cubic feet

Statement is false.

Option (2)

Since, \(V=\pi r^{2} h\)

And \(h(r)=3.5r\)

Therefore, \(V[h(r)]=\pi r^{2}(3.5r)\)

\(V[h(r)]=3.5\pi r^{3}\)

Domain of the function 'V' will be \(r>0\).

Statement is true.

Option (3)

Output of V is the input of h.

From the function,

\(V[h(r)]=3.5\pi r^{3}\)

Volume (output value) of the silo depends on the output value of \(h(r)\).

Therefore, statement is false.

Option (4)

\(V[h(r)]=3.5\pi r^{3}\)

Volume depends on the radius of the cylinder.

Since, output value of the volume depends on the radius.

Statement is true.

Options (2) and (4) are true.

To access the first element of an array of integers called "numbers," you can use the expression:
numbers[0]`
This expression uses the array name "numbers" and the index "0" to access the first element.

To access the last element of "numbers," assuming it contains 10 elements, use the expression:

`numbers[9]`

Here, we use the index "9" since arrays are zero-indexed, meaning the last element in a 10-element array has an index of 9.
To access the first element of the array called numbers, we would use the expression "numbers[0]."

To access the last element of the array, assuming it contains 10 elements, we would use the expression "numbers [9]" since arrays are zero-indexed in most programming languages.

To access the last element of the array regardless of its length, we can use the expression "numbers [numbers.length-1]," which subtracts 1 from the length of the array to access the last element.
To access the last element, regardless of its length, use the expression:

'numbers [numbers. length - 1]'

This expression uses the "length" property of the array to find the total number of elements and subtracts 1 to get the correct index for the last element.
