Given that -3(a-b)<0, which is greater a or b

The graph below is a graph of a function in the form of f(x) = eˣ,

where ‘e’ is the mathematical constant known as Euler's number and is approximately equal to 2.718.

An exponential function has an output that increases rapidly with increasing inputs.

This function is an exponential function, which means that the output increases at an exponential rate as the input increases.

The graph shows that the output, which is represented by the y-axis, increases rapidly as the input, which is represented by the x-axis, increases.

This is a characteristic of an exponential function, which is why this graph is a representation of the function f(x) = eˣ.

The other three functions, f(x) = e.x, f(x) = log x and f(x) = ln x, do not represent the graph as they are not exponential functions.

The value of the computer after 5 years is $189.84 and [tex]v = 800 * (3/4)^t[/tex] , where v is the value of the computer t years after it is purchased.

1. The computer costs $800 initially and loses 1/4 or 25% of its value every year. We can represent this decrease in value using the following formula:

[tex]v = 800 * (1 - 1/4)^t[/tex]

where v is the value of the computer t years after it is purchased. Simplifying this equation, we get:

[tex]v = 800 * (3/4)^t[/tex]

2. To find the value of the computer when t is 5, we can substitute t = 5 into the equation we derived in step 1:

[tex]v = 800 * (3/4)^5[/tex]

[tex]v = 800 * 0.2373[/tex]

[tex]v = 189.84[/tex]

This means that the value of the computer after 5 years is $189.84. This value is less than the initial cost of the computer, which was $800. It indicates that the computer has significantly depreciated in value over time, losing approximately 76% of its initial value.

The value of t according to the given conditions equals 4.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

The t-value can be calculated by dividing the mean difference by the standard error of the mean difference.

The formula for calculating t is:

t = (mean difference) / (standard deviation / sqrt(n))

Given that the mean difference equals 1.2, the standard deviation of the difference equals 1.5, and n equals 25.

Therefore the t-value can be calculated as follows:

t = (1.2) / (1.5 / sqrt(25)) = (1.2) / (1.5 / 5)= (1.2) / (0.3)= 4

Therefore, t equals 4.

Step-by-step explanation:

The hyperbola's standard equation is thus:[tex]((x - 5)^2) / 4 - ((y + 2)^2) / 1 = 1[/tex]as by the distance down the conjugate axis.

Variables, numbers, and mathematical operations like addition, subtraction, multiplication, and division are frequently included. Equations are used in many disciplines, including physics, engineering, economics, and finance, to describe connections between quantities and to solve problems. For instance, the formula "2x + 5 = 11" states that the number 11 is equal to the sum of the two variables x and 5. We can determine that x equals 3 by finding a solution for x. On the basis of mathematical relationships, equations enable us to locate unknown values and create predictions.

given

The hyperbola shown above has a center at and a horizontal transverse axis (5, -2). Its vertices are at (3, -2) and (8, -2), while its foci are at (2, -2) and (8, -2). (7, -2).

The typical equation for a hyperbola with a center at (h, k) and a horizontal transverse axis is:

((x - h)2) / a2 - ((y - k)2) / b2) equals one.

where an is the distance along the transverse axis from the center to a vertex, and b is the distance along the conjugate axis from the center to a point on the hyperbola.

In this instance, an equals 2, since the distance along the transverse axis between the center and a vertex is 2.

B = 1 because the distance down the conjugate axis from the hyperbola's center to any point is 1.

The hyperbola's standard equation is thus:[tex]((x - 5)^2) / 4 - ((y + 2)^2) / 1 = 1[/tex]as by the distance down the conjugate axis.

The correct answer is: √(6² + 2²), and tan⁻¹(2/6) represents the magnitude and direction angle of the vector.

What is Pythagoras' Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The magnitude of a vector is the length of the vector. For a vector that passes from the origin to the point (6,2),

the magnitude can be calculated using the Pythagorean theorem, which states that for a right triangle with legs of length a and b and hypotenuse of length c,

c² = a² + b².

In this case, the vector is the hypotenuse of a right triangle with legs of length 6 and 2, so the magnitude is:

magnitude = √(6² + 2²) = √(40) = 2*√(10)

The direction angle of a vector is the angle that the vector makes with the positive x-axis, measured counterclockwise. The direction angle can be calculated using the inverse tangent function, which is the inverse of the tangent function. In this case, the direction angle is:

direction angle = tan⁻¹(2/6) = tan⁻¹(1/3)

Therefore, the correct answer is: √(6² + 2²), and tan⁻¹(2/6) represents the magnitude and direction angle of the vector.

The answer of the given question based on the right angle triangle is , the height of the light pole to the nearest tenth of a foot is 9.3 feet.

A right-angled triangle, also known as a right triangle, is a triangle that has one angle equal to 90 degrees. The side opposite right angle is called hypotenuse, and other two sides is called legs. The leg opposite to a particular acute angle is known as the opposite side, and the leg adjacent to it is known as the adjacent side.

The Pythagorean theorem is a fundamental theorem that applies to all right-angled triangles. It states that square of hypotenuse of right-angled triangle is equal to sum of squares of its two legs

To determine the height of the light pole, we can use similar triangles.

Let's call height of light pole be  "x". Then we have:

(height of stop sign) / (length of stop sign's shadow) = (height of light pole)/(length of light pole's shadow)

Substituting the given values, we have:

8/12 = x/14

Simplifying this equation, we get:

x = (8/12) * 14 = 9.33 feet

Therefore, the height of the light pole to the nearest tenth of a foot is 9.3 feet.

To solve this system of equations graphically, we need to plot the lines represented by each equation on a coordinate plane and find their intersection point (if it exists).

First, let's rearrange the first equation to solve for y:

[tex]y = (2/3)x + 4[/tex]

Now, we can plot this line by finding two points on it. For example, when x = 0, y = 4, and when x = 3, y = 6. We can then connect these points with a straight line.

[tex]y < 4x[/tex]. This is an inequality, so we'll shade the region below the line y = 4x. To plot the line itself, we can again find two points on it. When x = 0, y = 0, and when x = 1, y = 4. Connecting these points.

we need to shade the region below this line, since y is less than 4x. This region includes all points on the coordinate plane that satisfy y < 4x. We can shade it by drawing a dotted line along the line y = 4x and shading the region below.

the product of the equation is positive 6(3×2)

then we find the factors of 6 which give us the product 6 and the sum of-5

the factors are-3 and -2

we then substitute negative 5 with these factors

it then be 3x^2-3x-2x+2=0

then we group factorise

we will have 3x(x-1)-2(x-1)=0

we find the common factors of the 2 groups

we will then have (x-1)(3x-2)=0

The probability of getting two heads and one tail in any order is 3/8.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. For example, the probability of flipping a coin and it landing heads up is 0.5, because there are two equally likely outcomes (heads or tails) and one of them is heads.

Probabilities can also be expressed as percentages or fractions. For instance, a probability of 0.25 can be expressed as a percentage of 25%, or as a fraction of 1/4.

According to the question:
The sample space for flipping three coins is:
HHH

HHT

HTH

THH

HTT

THT

TTH

TTT

where H represents heads and T represents tails.

Out of these eight outcomes, there are three outcomes in which two heads and one tail come up in any order: HHT, HTH, and THH. Therefore, the probability of getting two heads and one tail in any order is 3/8, or 0.375, which can also be written as a fraction.

To see why this is the case, you can also use a tree diagram to represent the sample space:
     H              T

   /   \          /   \

  H     T        H     T

 / \   / \      / \   / \

H   T H   T    H   T H   T

Each branch represents the outcome of one coin flip, and the branches lead to the possible outcomes of flipping three coins. The outcomes with two heads and one tail are HHT, HTH, and THH, which occur in three out of the eight possible outcomes, as previously stated. Therefore, the probability of getting two heads and one tail in any order is 3/8.

Answer:

4y = x + 7.

Step-by-step explanation:

The slope of a line perpendicular to a line of slope m = -1/m

So the slope of the required line = -1/ (-4) = 1/4.

y - y1 = m(x - x1)

y - 2 = 1/4(x - 1)

y = 1/4(x - 1) + 2

y =  1/4x - 1/4 + 2

y = 1/4x + 7/4

For the first student with a score of 1910, the z-score is: 1.34 ,For the second student with a score of 1220, the z-score is: 0.81 , For the third student with a score of 2160, the z-score is:2.14 , For the fourth student with a score of 1370, the z-score is: -0.34 and , out of the four students, only the one with the test score of 2160 is considered an unusual score based on the z-score.

To find the z-score for a given data point, we use the formula:

z = (x - μ) / σ

where x is the data point, μ is the mean, and σ is the standard deviation.

For the first student with a score of 1910, the z-score is:

z = (1910 - 1479) / 317 = 1.34

For the second student with a score of 1220, the z-score is:

z = (1220 - 1479) / 317 = -0.81

For the third student with a score of 2160, the z-score is:

z = (2160 - 1479) / 317 = 2.14

For the fourth student with a score of 1370, the z-score is:

z = (1370 - 1479) / 317 = -0.34

Now, we need to determine whether any of these z-scores are unusual. One way to do this is to use the rule of thumb for normal distributions, which states that about 68% of the data falls within one standard deviation of the mean, about 95% of the data falls within two standard deviations of the mean, and about 99.7% of the data falls within three standard deviations of the mean.

Using this rule, we can say that a z-score greater than 2 or less than -2 is unusual, since it corresponds to data that falls more than two standard deviations from the mean.

From the z-scores we calculated, only the third student with a z-score of 2.14 falls outside of this range and can be considered an unusual score.

Therefore, out of the four students, only the one with the test score of 2160 is considered an unusual score based on the z-score.

A 2-column table with 4 rows.

- Column 1 is labeled cups with entries 1, 2, 4, 8.

- Column 2 is labeled tablespoons with entries 16, 32, 64, 128.

In this table, the first row tells us that there is 1 cup which is equivalent to 16 tablespoons. The second row shows that 2 cups is equal to 32 tablespoons. The third row indicates that 4 cups is equal to 64 tablespoons. And finally, the fourth row states that 8 cups is equal to 128 tablespoons.

This table follows the relationship where for every 1 cup, there are 16 tablespoons. So, to find the number of tablespoons for a given number of cups, you can use this table as a reference.

For example, if you have 3 cups, you can find the number of tablespoons by looking at the table. Since there is no row for 3 cups in the given table, you can approximate it by knowing that 2 cups is equal to 32 tablespoons, and 4 cups is equal to 64 tablespoons. Therefore, 3 cups would be somewhere between 32 and 64 tablespoons.

From the following option given, the correct option is option (3) - detect assignable cause variations versus normal random variations in the process.

The objective of statistical process control (SPC) is to monitor and control a process to ensure that it operates within its specifications and meets the desired quality level. One of the main goals of SPC is to distinguish between normal random variation in the process and variation that is caused by assignable or special causes.

By identifying and eliminating the assignable causes of variation, the process can be improved and the quality of the output can be maintained or improved over time. Therefore, the primary objective of SPC is to detect assignable cause variations versus normal random variations in the process.

Options 1, 2, and 4 are related to quality control and monitoring, but they do not capture the essence of what SPC is trying to achieve. SPC is focused on monitoring and improving the process, rather than simply accepting or rejecting batches of raw materials or finished goods or identifying variable versus attribute measures.
