Given that;

Expressions are,

⇒ 6x + v = 4x + w

⇒ ax + 9 = 2x + b

⇒ 7x - w = vx+4

⇒ 6 - wx = vx + 4

⇒ 3(wx - v) = 4(x + v)

We can simplify as;

⇒ 6x + v = 4x + w

⇒ 6x - 4x = w - v

⇒ 2x = w - v

⇒ x = 1/2 (w- v)

⇒ ax + 9 = 2x + b

⇒ ax - 2x = b - 9

⇒ (a - 2)x = b - 9

⇒ x = (b - 9)/(a - 2)

⇒ 7x - w = vx+4

⇒ 7x - vx = 4 + w

⇒ (7 - v) x = 4 + w

⇒ x = (4 + w) / (7 - v)

⇒ 6 - wx = vx + 4

⇒ vx + wx = 6 - 4

⇒ (v + w)x = 2

⇒ x = 2 / (v + w)

⇒ 3(wx - v) = 4(x + v)

⇒ 3wx - 3v = 4x + 4v

⇒ 3wx - 4x = 7v

⇒ (3w - 4)x = 7v

⇒ x = 7v/(3w - 4)

The total number of different sandwiches that can be made is 36.

There are m x n methods to execute both tasks separately if there are m ways to perform one job and n ways to complete another, according to the multiplication principle of counting, a key counting principle in combinatorics. When we need to count the number of outcomes in a scenario where the outcomes are influenced by a number of separate decisions, we utilise this approach. When there are only a limited number of options available for each activity, as there are in the sandwich-making dilemma, it is very helpful. We may calculate the total number of outcomes by multiplying the number of options for each assignment.

For the given number of toppings we can use the counting principle.

3 x 4 x 3 = 36

Hence, the total number of different sandwiches that can be made is 36.

By altering the x and y values, one can algebraically determine a function's inverse.

In mathematics, the word inverse refers to the opposite of another operation. Let us look at some examples to understand the meaning of inverse.  The addition means to find the sum, and subtraction means taking away. So, subtraction is the opposite of addition.

Because they enable the reversal of mathematical operations, inverse procedures are crucial for solving equations (e.g. logarithms, the inverses of exponential functions, are used to solve exponential equations).

y= (x= 2)² - 4 → x = (y+2)²-4

x+ 4 = (y+2)²

≠√x=4 =y+2

≠√x=4-2=y

f-1 (x)=≠√x+4-2

y= √12+4-2

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Answer:

a. Variables:

Let's define the variables for the problem:

t: time in minutes (the variable we are solving for)

h1: altitude of the descending airplane in feet

h2: altitude of the ascending airplane in feet

b. System of Equations:

Based on the given information, we can create a system of equations:

Equation 1: h1 = 59,400 - 3,000t (altitude of descending airplane)

Equation 2: h2 = 0 + 2,400t (altitude of ascending airplane)

c. Solving the System using Graphing:

To solve the system using graphing, we need to plot the two equations on a graph and find the point of intersection. Here's the graph:

[Graph]

From the graph, we can see that the two lines intersect at a point. The x-coordinate of the point of intersection represents the time (t), and the y-coordinate represents the altitude (h) where the two airplanes are at the same altitude.

d. Solving the System using Substitution or Elimination:

To check our graphing work, we can solve the system using either substitution or elimination. Let's use substitution:

From Equation 1: h1 = 59,400 - 3,000t

Substitute h1 into Equation 2:

59,400 - 3,000t = 2,400t

Add 3,000t to both sides:

59,400 = 5,400t

Divide both sides by 5,400:

t = 11

Now, substitute the value of t back into either Equation 1 or Equation 2 to find the altitude (h) at that time:

h1 = 59,400 - 3,000 * 11

h1 = 59,400 - 33,000

h1 = 26,400 feet

Therefore, the two airplanes will be at the same altitude of 26,400 feet after approximately 11 minutes.

Explanation of Methods:

Graphing: Graphing the equations provides a visual representation of the problem and helps identify the point of intersection. However, it may not provide an exact value, and the precision depends on the accuracy of the graph.

Substitution or Elimination: These algebraic methods allow for precise calculations and the exact determination of the time and altitude at which the airplanes meet. They require more steps and calculations but offer a more accurate solution.

In the context of the problem, the solution means that after approximately 11 minutes, both airplanes will be at the altitude of 26,400 feet. At this moment, the descending airplane will have descended to the same altitude as the ascending airplane is ascending, resulting in the two airplanes being at the same height above the ground.

The decision rule is  

Reject the null hypothesis

Step-by-step explanation:

From the question we are told that

   The first sample mean is  \(\= x_1 = 75.1\)

    The first sample standard deviation is  \(s_1 = 4.5\)

    The first sample size \(n_1 = 11\)

    The second sample mean is  \(\= x_2 = 66.2\)

    The second sample standard deviation is  \(s_2 = 5.1\)

     The second sample size is  \(n_2 = 9\)

     The significance level is  \(\alpha = 0.01\)

The null hypothesis is  \(H_o : \mu_1 = \mu_2\)

The alternative hypothesis is  \(H_a : \mu_1 \ne \mu_2\)

Generally the pooled standard deviation is mathematically represented as

      \(s = \sqrt{ \frac{(n_ 1 - 1) s_1^2 + (n_2 - 1) s_2^2}{n_1 + n_2 -2 } }\)

=>  \(s = \sqrt{ \frac{(11 - 1) 4.5^2 + (9 - 1) 5.1^2}{11 + 9 -2 } }\)

=>  \(s = 4.78\)

Generally the degree of freedom for the is mathematically represented as

       \(df = [ \frac{[\frac{s_1^2 }{n_1} + \frac{s_2^2}{ n_2} ]^2}{[\frac{[\frac{s_1^2}{n_1} ]^2}{n_1 - 1 } ] + [\frac{[\frac{s_2^2}{n_2} ]^2}{n_2 -1} ]} ]\)

=>   \(df = [ \frac{[\frac{4.5^2 }{11} + \frac{5.1^2}{9}  ]^2}{[\frac{[\frac{4.5^2}{11} ]^2}{ 11 - 1 } ] + [\frac{[\frac{5.1^2}{9} ]^2}{9 -1}  ]} ]\)

=>   \(df = 16 \)

Generally the test statistics is mathematically represented as

      \(t = \frac{\= x_1 - \= x_2}{ \sqrt{\frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2} } }\)

=> \(t = \frac{ 75.1 - 66.2 }{ \sqrt{\frac{ 4.5^2 }{ 11} + \frac{5.1^2}{ 9} } }\)

=> \(t = 4.092\)

Generally the student distribution table the probability of  \(t = 4.092\) to the right at a degree of freedom of  \(df = 16 \)  is  

     \(P( T > 4.092 ) = 0.00042536\)

Generally the p-value is mathematically represented as

      \(p-value = 2 * P(T > 4.092)\)

=>    \(p-value = 2 * 0.00042536\)

=>    \(p-value = 0.001\)

From the value obtained we see that  \(p-value < \alpha\) hence we

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

The solution to the nonlinear system of equations is (x, y) = (-3, -2) and (x, y) = (1, 6). These points represent the coordinates where the two equations intersect and satisfy both equations simultaneously.

To solve the nonlinear system of equations:

Equation 1: \(y = -x^2 + 7\)

Equation 2: y = 2x + 4

We can equate the right sides of both equations since they both represent y.

\(-x^2 + 7 = 2x + 4\)

To simplify the equation, we can rearrange it to be in the standard quadratic form:

\(x^2 + 2x - 3 = 0\)

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:

(x + 3)(x - 1) = 0

From this equation, we get two possible solutions:

x + 3 = 0 => x = -3

x - 1 = 0 => x = 1

Now, we substitute these x-values back into either equation to find the corresponding y-values.

For x = -3:

y = 2(-3) + 4

y = -6 + 4

y = -2

For x = 1:

y = 2(1) + 4

y = 2 + 4

The equation that models the relationship between the number of guests, x, and the total charge, y is A. y = 450 + 125x. The base charge for a single guest is $450, and for each additional guest, the charge increases by $125. So, we add 125 times the number of additional guests to the base charge of $450.

The point in Figure 2 that corresponds to point L in Figure 1 is the midpoint of line segment NP.

When two figures are congruent, it means that they have the same shape and size. This implies that corresponding points in the two figures have the same position and distance from each other.

In Figure 1, the points I, J, L, K, N, P, and Q are labeled. To find the point in Figure 2 that corresponds to point L, we need to look for a point that has the same relative position and distance as point L in Figure 1.

From Figure 1, we can see that point L is the midpoint of the line segment JK. Therefore, to find the corresponding point in Figure 2, we need to look for a point that is the midpoint of the line segment that corresponds to JK. In Figure 2, the line segment that corresponds to JK is NP, and the midpoint of NP corresponds to the point that is equivalent to point L. Therefore, the point that corresponds to point L in Figure 2 is the midpoint of line segment NP.

It is important to note that identifying corresponding points in congruent figures is a fundamental concept in geometry and is often used to solve problems involving congruence and similarity.
