The total change in yards for the two plays 21 yards lost

Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043. A set of integers, which is represented as Z, includes:

Positive Numbers: A number is positive if it is greater than zero. Example: 1, 2, 3 . . .

Negative Numbers: A number is negative if it is less than zero. Example: -1, -2, -3 . . .

Zero is defined as neither a negative number nor a positive number. It is a whole number.

In first play= 14 yards lost= -14

In next play = 7 yards lost = -7

So,

the total change in yards is = -14 + (-7)

                                              =-14-7

                                              = -21 yards

Answer:

1. (2 - 3i)(2 + 3i) = 4 + 9 = 13

2. (-3 + 4i)(-3 - 4i) = 9 + 16 = 25

3. (-1 - i√2)(-1 + i√2) = 1 + 2 = 3

The product of the complex number and its conjugate for 2- 3i, -3 + 4i, and -1 - √2i is 13, 25, and 3 + 2√2 respectively.

Let us find the product of the complex number and its conjugate for each of the complex numbers:

1. 2- 3i

The conjugate of 2- 3i is 2+3i.The product of 2- 3i and 2+3i is:

(2 - 3i)(2 + 3i)

= 4 + 6i - 6i - 9i²

= 4 + 9= 13

Therefore, the product of 2- 3i and its conjugate is 13

.2. -3 + 4i

The conjugate of -3 + 4i is -3 - 4i.The product of -3 + 4i and -3 - 4i is:

(-3 + 4i)(-3 - 4i) = 9 - 12i + 12i - 16i²

= 9 + 16

= 25

Therefore, the product of -3 + 4i and its conjugate is 25.

3. -1 - √2i

The conjugate of -1 - √2i is -1 + √2i.The product of -1 - √2i and -1 + √2i is:

(-1 - √2i)(-1 + √2i)

= 1 - √2i + √2i - (i² * 2)

= 1 + 2

= 3

Therefore, the product of -1 - √2i and its conjugate is 3.The product of -1 - √2i and its conjugate is 3 + 2√2.

Therefore, The product of the complex number and its conjugate for 2- 3i, -3 + 4i, and -1 - √2i is 13, 25, and 3 + 2√2 respectively.

Considering the definition of an equation and the way to solve it, the equation for the total cost is 5×(x +18) and the price of one ticket is $171.

An equation is an algebraic equality in which there are unknowns that you want to calculate  in addition to certain known data.

The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" the price of one ticket, and knowing that:

the total cost can be expressed as:

Total cost= number of tickets×(price of one ticket +price of travel insurance)

Total cost= 5×(x +18)

If the total cost is $945, you get that:

945= 5×(x +18)

945 ÷5= x + 18

189= x + 18

189 - 18= x

171= x

The system of linear equations are;

a + b = 5.30

a + b = 7

Expressing the information as a system of linear equations:

Consider that apples = a, oranges = b

If $5.30 is charged for one apple and one orange, then we get the equation as

a + b = 5.30 - - - (1)

If $14 is charged for 2 apples and 2 oranges,  then we get the equation as ;

2a + 2b = 14 - - - - (2)

a + b = 7

Since both equations give varying combined cost for an equal amount of fruit, so a unique cost cannot be obtained for each fruit from the systems of equation using a simultaneous equation process.

From (1)

a = 5.30 - b

Put a, b in (2)

2(5.30 - b) + 2b = 14

Therefore , the solution of this given problem is we can solve the non right triangle with the help of law of sines.

The side-angle connection of oblique (non-right) triangles is known as the Law of Sines. It simply asserts that all sides and angles in a particular triangle have the same ratio between the length of a side and the sine of the angle opposite that side.

Here,

Since both c(A) and a(C) are equal to x in this case, the transitive property states that they must also be equal to one another:

csin(A)=asin(C)

In order to acquire the simple-to-remember formulation of the law of sines, we typically divide both sides by ac:

sin(C)/c = sin(A)/a

The other two elevations, derived from angles A and C, might also be used to derive the same relations for the other angle pairings. The sum of these is known as the sine law. It's down below in the green box.

Size of sample needed to determine the percentage of people with give margin of error is equal to 1691.

As given in the question,

Margin of error = 2%

                          = 0.02

Sample proportion 'p' = 0.5

⇒ (1 - p) = 1 - 0.5

             = 0.5

Let 'n' represents the sample size

Z- value at confidence interval 90% = 1.645

Formula used

Margin of error = z-value √ [p( 1-p)/n]

Substitute the value we get,

0.02 = 1.645 √ (0.5)(0.5)/n

Squaring on both the side

0.0004 = 2.706025 ( 0.25/n)

⇒ n = ( 2.706025 × 0.25 )/ 0.0004

⇒ n = 1691.26

⇒ n ≈ 1691

Therefore, size of sample needed with given margin of error is equal to 1691.

To find the number of triangles with vertices of three different colors, we need to consider the combinations of colors we can choose from the given set of points.

We have 8 red points, 4 green points, and 6 blue points. To form a triangle with vertices of three different colors, we need to choose one point from each color group.

First, let's choose one red point. We have 8 options for this.

Next, let's choose one green point. We have 4 options for this.

Finally, let's choose one blue point. We have 6 options for this.

To determine the total number of triangles, we need to multiply the number of options for each color:

Total number of triangles = Number of options for red points × Number of options for green points × Number of options for blue points

                      = 8 × 4 × 6

                      = 192

Therefore, there are 192 triangles with vertices of three different colors.

It's worth noting that the order in which we choose the points does not matter because we are counting the number of distinct triangles. So, we are not considering permutations but rather combinations of colors.

The point (16, -99) is not a perfect fit in the linear model, and the slope-intercept equation for the remaining four data points (-8, 9), (-6, -9), (-2, -18), and (8, -63) is y = (-15/2)x + 3; the y-intercept (3) represents the net approval rating for the president when there is no change in the Dow Jones, and the slope (-15/2) indicates that for every 1-point increase in the Dow Jones, the net approval rating is expected to decrease by 7.5 percentage points.

To determine which point is not a perfect fit in the linear model, we need to compute the slopes for each pair of consecutive data points.

The slope of a linear model represents the rate of change between the two variables.

Using the given data points:

Points: -8, -6, -2, 8, 16

Percentage Points: 9, -9, -18, -63, -99

Let's compute the slopes:

Slope between (-8, 9) and (-6, -9):

slope = (change in percentage points) / (change in points)

slope = (-9 - 9) / (-6 - (-8))

slope = -18 / 2

slope = -9

Slope between (-6, -9) and (-2, -18):

slope = (-18 - (-9)) / (-2 - (-6))

slope = -9 / 4.0

slope = -2.25

Slope between (-2, -18) and (8, -63):

slope = (-63 - (-18)) / (8 - (-2))

slope = -45 / 10

slope = -4.5

Slope between (8, -63) and (16, -99):

slope = (-99 - (-63)) / (16 - 8)

slope = -36 / 8

slope = -4.5

The slopes for the first three pairs of points (-9, -2.25, -4.5) match, indicating a consistent linear relationship.

However, the slope between the last two points is -4.5, not -4.25 like the others.

Therefore, the point (16, -99) is not a perfect fit.

Removing the point (16, -99), we have four remaining data points:

(-8, 9), (-6, -9), (-2, -18), and (8, -63).

To find the slope-intercept equation for the linear model that passes through these four points, we can use the formula:

y = mx + b

Using the slope formula with two of the remaining points:

-9 = m(-6) + b

-18 = m(-2) + b

Solving these two equations simultaneously, we find:

m = -9/4

b = 9/2

So the slope-intercept equation for the linear model is:

y = (-9/4)x + 9/2

The practical meaning of the y-intercept (9/2) is that when the previous day's change in the Dow Jones is 0 points, the net approval rating for the president of the United States is expected to be 9/2 percentage points, or 4.5 percentage points.

The practical meaning of the slope (-9/4) is that for every 1-point increase in the previous day's change in the Dow Jones, the net approval rating for the president of the United States is expected to decrease by 9/4 percentage points, or 2.25 percentage points.

Mill claims that of any two pleasures, one is preferable to the other if and only if it is more desirable or valuable to a person. Mill's understanding of pleasure is not solely based on its intensity, duration, or certainty, but rather on the qualitative experience of pleasure itself.

Mill believes that some pleasures are of a higher quality than others, and that people who have experienced both kinds of pleasure would choose the higher pleasure over the lower one. Mill argues that the preference for higher pleasures is a result of the cultivation of one's mental and emotional capacities. He suggests that the ability to appreciate higher pleasures is developed through education and exposure to cultural and intellectual experiences.

Therefore, Mill's theory of pleasure and preference is based on a broader understanding of human nature and the value of experience, rather than just the quantitative features of pleasure.

The AD curve in an AS-AD diagram is most relevant to Keynes's Law. The correct option is d.

In an AS-AD (Aggregate Supply-Aggregate Demand) diagram, Keynes's Law is most relevant to the AD curve. Keynes's Law, proposed by economist John Maynard Keynes, states that aggregate demand (AD) determines the level of economic activity and that fluctuations in AD can lead to periods of economic expansion or contraction.

The AD curve represents the total demand for goods and services in an economy at different price levels. It shows the relationship between the overall price level and the quantity of real GDP demanded. When the AD curve shifts to the right, it indicates an increase in overall demand, leading to higher levels of output and employment. Conversely, a shift to the left indicates a decrease in overall demand, which may lead to lower output and employment.

Keynes's Law emphasizes the importance of aggregate demand management by the government through fiscal and monetary policies to stabilize the economy and achieve full employment. Thus, the AD curve plays a central role in illustrating the concepts and implications of Keynes's Law in an AS-AD diagram. The correct option is d.

Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)

Substitute the given vector into the expression for vec t.

Recall that: vec t = 4 vec u +6 vec v

vec t = 4(-1,4)+6(3,-2)

vec t = (4(-1), 4(4)) + (6(3), 6(-2))

vec t = (-4, 16) + (18, -12)

vec t = (-4+18, 16+(-12))

vec t = (14, 16-12)

vec t = (14, 4)

Hence an ordered pair to represent vec t in the equation is (14, 4)
