The event with a sample space of S = {A, B} is (d) choosing a tile from a pair of tiles, one with the letter A and one with the letter B.

From the question, we have the following parameters that can be used in our computation:

Sample space of S = {A, B}

In probability, the sample space is the set of all possible outcomes of a random event.

In the case of choosing a tile from a pair of tiles, one with the letter A and one with the letter B, there are only two possible outcomes: A or B.

Therefore, the sample space S is {A, B}.

In contrast, for the other events listed:

In each of these events, there are more than two possible outcomes, so the sample space is a set with more than two elements.

Answer:

The annual interest you would earn on each bond depends on the bond's coupon rate, which can be calculated by dividing the bond's current yield (Column 2) by 100. For Bond A and C, the coupon rate would be 7.5%, and for Bond X and Y, it would be 8.4%. The annual interest you would earn on each bond would be the coupon rate multiplied by the bond's face value (Column 1). For Bond A and C, the annual interest would be 7.5% * $15 = $1.125, and for Bond X and Y, it would be 8.4% * $15 = $1.26.

If Jane took 30 min to drive her boat upstream to water-ski at her favorite spot. her boat speed in still water is;3 km/h.

Let's x represent the  Jane's boat speed in still water

Upstream, her speed was x - 2 km/h.

Downstream, her speed was x + 2 km/h.

Let's d represent the distance between the start and end point

Let the  time it takes to cover d at a speed of x - 2 km/h=  30 min.

Let the  time it takes to cover d at a speed of x + 2 km/h=  10 min.

So we have:

d / (x - 2) = 30 min and

d / (x + 2) = 10 min.

Multiplying both sides of each equation

d * x - 2d = 30 * (x - 2)

d * x + 2d = 10 * (x + 2).

Adding the two equations and solve for x

2d * x = 40 * x + 20

20 * x = 40 * x + 20

20 * x = 60 * x

x= 3 km/h

Therefore Jane's boat speed in still water is 3 km/h.

It took Bailey 45 days to paint the house and Andrew 11.25 days to paint the house.

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, Andrew can paint the neighbor's house 4 times as fast as Bailey. Andrew and Bailey worked together, it took them 5 days.

Let the time it took Bailey to paint the house be x days, and the time it took Andrew to paint the same house be y. Then,

Establishing the system of equation,

1/x + 1/y = 1/9. . . (1)

x = 4y. . . (2)

Putting (2) into (1) gives,

1/4y + 1/y = 1/9

5/4y = 1/9

4y = 5 x 9 = 45

y = 11.25

The equation of the line that runs through the point (0,-1) and (1,2) in slope-intercept form is y = 3x - 1.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

From the diagram, the line runs through the point (0,-1) and (1,2).

First, we determine the slope of the line

Slope m = change in y / change in x

Slope m = (2 - (-1)) / (1 - 0)

Slope m = (2 + 1) / (1 - 0)

Slope m = 3/1

Slope m = 3

Next, plug the slope m = 3 and point (0,-1) into the point slope formula.

y - y₁ = m( x - x₁ )

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

y + 1 = 3x - 0

y + 1 = 3x

Subtract 1 from both sides

y + 1 - 1 = 3x -1

y = 3x - 1

Therefore, the equation of the line is y = 3x - 1.

Answer:

Step-by-step explanation:

From the properties of similarity, the value of x is 24.

Euclidean geometry states that two objects are comparable if they have the same shape or the same shape as each other's mirror image. More specifically, by uniformly scaling (enlarging or decreasing), maybe with additional translation, rotation, and reflection, one can be created from the other. This indicates that one object may be properly aligned with the other object by rescaling, moving, and reflecting it. When two things are comparable to one another, one is consistent with the outcome of a specific uniform scaling of the other.

By comparing corresponding sides of the shapes, we get that

6/9 = 14/21 = 2/3

So that,

16/x =2/3

multiply both sides by 3/2 we get,

(16/x)*(3/2) = 1

multiply both sides by x we get,

16*3/2 = x

⇒ x = 48/2

⇒ x = 24

The rate of change of the height is approximately -1.67 meters per minute.

The volume of a cone can be written as V = (1/3)πr²h.

Differentiating with respect to time t, we get

dV/dt = (1/3)π (2rh dr/dt + r² dh/dt)

Given that the radius is decreasing at a constant rate of 1 meter per minute and the volume is decreasing at a rate of 61 cubic meters per minute, we can substitute these values into the equation to find dh/dt:

61 = (1/3)π (2rh + r² dh/dt)

dh/dt = (61 - (2rh)) / (r² * (1/3)π)

Substituting in the given values of r = 2 meters and h = 41 cubic meters, we get:

dh/dt = (61 - (2 * 2 * 41)) / (2² * (1/3)π)

dh/dt = (61 - 164) / (4 * (1/3)π)

dh/dt = -103 / (4 * (1/3)π)

Approximating π to 3.14, we get

dh/dt = -103 / (4 * (1/3) * 3.14)

dh/dt ≈ -1.67

So the rate of change of the height is approximately -1.67 meters per minute.

d) 6(2x + 4)² = (2x + 4) + 2  and,

e) 6x⁴ = -x² + 5.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must contain at least one term of the second degree.

Given equations to find the  equations that are quadratic in form,

Standard form refers to the quadratic function f(x) = a(x - h)² + k, where a is not equal to zero. The graph opens either upward or downward depending on the value of a. The vertex is the point, while the line of symmetry is the vertical line x = h.

Step-by-step explanation:

Answer:Let's call the two numbers x and y. We know that:

xy = 72

x + y = -38

We can use the first equation to solve for one of the variables in terms of the other:

x = 72/y

Then, we can substitute this expression into the second equation:

72/y + y = -38

y^2 + 72 = 38y

y^2 - 38y + 72 = 0

This is a quadratic equation that can be solved using the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -38, c = 72.

Plugging in these values, we get:

y = (38 ± √(38^2 - 4(1)(72))) / 2(1)

y = (38 ± √(1444)) / 2

y = (38 ± 38) / 2

So, we have two solutions for y:

y = 38 / 2 = 19

y = -38 / 2 = -19

With either of these values for y, we can use the first equation to solve for x:

x = 72/y = 72/19 = 3.8

or

x = 72/-19 = -3.8

So, the two numbers whose product is 72 and whose sum is -38 are x = 3.8 and y = 19, or x = -3.8 and y = -19.

Step-by-step explanation:

Let's call the two numbers x and y. We know that:

xy = 72

x + y = -38

We can use the first equation to solve for one of the variables in terms of the other:

x = 72/y

Then, we can substitute this expression into the second equation:

72/y + y = -38

y^2 + 72 = 38y

y^2 - 38y + 72 = 0

This is a quadratic equation that can be solved using the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -38, c = 72.

Plugging in these values, we get:

y = (38 ± √(38^2 - 4(1)(72))) / 2(1)

y = (38 ± √(1444)) / 2

y = (38 ± 38) / 2

So, we have two solutions for y:

y = 38 / 2 = 19

y = -38 / 2 = -19

With either of these values for y, we can use the first equation to solve for x:

x = 72/y = 72/19 = 3.8

or
