Write an equation of the line below.

x=2,-13

Hope this helps

The total number of copies sold to date is approximately 369,767.

An equation can be described mathematically as a statement that supports the equality of two expressions joined by the equals sign "=". For instance, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. "=" is the sign that connects these two expressions.

Let's assume the total number of copies sold to date as x.

We know that the number of copies sold in the first month is 31,800, which is 8.6% of the total number of copies sold to date.

So we can set up an equation as follows:

31,800 = 0.086x

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides by 0.086:

x = 31,800 / 0.086

x = 369,767.44

Therefore, the total number of copies sold to date is approximately 369,767.

Answer: a) The probability of matching the first five selected numbers to the later five numbers drawn is given by the formula:

P = (C(69,5) / C(69,5)) * (C(5,5) / C(26,1))

where C(n,r) is the number of combinations of n items taken r at a time. The first term in the product represents the number of ways to choose the first five numbers from the pool of 69, and the second term represents the probability of choosing the correct number from the second set of 26 numbers.

Simplifying the expression, we get:

P = (1) * (1/26) = 1/26

Therefore, the probability of matching the first five selected numbers to the later five numbers drawn is 1/26.

b) The probability of matching the sixth selected number to the later number drawn from the second set is given by:

P = C(1,1) / C(26,1) = 1/26

Therefore, the probability of matching the sixth selected number to the later number drawn is 1/26.

c) The probability of winning the jackpot is the product of the probabilities of matching the first five selected numbers to the later five numbers drawn and matching the sixth selected number to the later number drawn. Using the results from parts (a) and (b), we get:

P = (1/26) * (1/26) = 1/676

Therefore, the probability of winning the jackpot is 1 in 676.

Answer: For each hour spent driving, the distance increases by 59.3

miles.

Step-by-step explanation:

Your welcome!

Answer:

C)  For each hour spent driving, the distance increases by 59.3 miles.

Step-by-step explanation:

In the function f(x) = 59.3x + 58.3, the coefficient of x is 59.3.

This coefficient represents the rate of change or slope of the linear relationship between distance traveled (in miles) and time (in hours).

Specifically, it represents the speed of the car in miles per hour (mph).

This means that for each hour spent driving (each unit increase in time), the car travels an additional 59.3 miles, so its distance increases by 59.3 miles each hour. Hence, the car is traveling at a speed of 59.3 mph.

The value of the set for the given value of set complement is n(X ∩ Y) = 92.

In set theory, a set's complement The set of all U elements that are not in A is known as A. In other words, all the components that are in U but not in A are in A'. A' is the set of odd numbers, for instance, if U is the set of integers and A is the set of even integers. In many mathematical and computational applications, the complement of a set is a crucial idea in set theory.

Given that, n(U) = 100, n(X) = 51, n(Y) = 63 and n(XUY)' = 8.

Using the formula of union of two sets we have:

n(XUY)' = n(U) - n(X ∩ Y)

Substituting the values we have:

8 = 100 - n(X ∩ Y)

n(X ∩ Y) = 100 - 8

n(X ∩ Y) = 92

Hence, the value of the set for the given value of set complement is n(X ∩ Y) = 92.

g¹(x) = (x - 3)/2

c.)

g¹(x) = 2*f-1(x+3).

d. ) we obtain the graph of g¹(x) = 2f-1(x+3). and  g(x) = 2f(x) + 3.

(b) The inverse function of f(x) = 2*x is f-1(x) = x/2.

We found the  inverse function of g(x) = 2f(x) + 3 = 2(x) + 3, by isolating f(x):

g(x) = 2*f(x) + 3

(g(x) - 3)/2 = f(x)

f-1(x) = (x - 3)/2

(d)   we work on this graph f-1(x) and g¹(x),  by graphing f(x) = 2x and y = x/2 on the same set of axes.

shift the graph of f(x) to the right by 3 units to obtain the graph of f-1(x+3), and stretch it vertically by a factor of 2 to obtain the graph of g¹(x) = 2f-1(x+3).

The resulting graph should have a horizontal asymptote at y = 3 and pass through the points (0, -1.5) and (6, 4.5).

To produce g(x) from f(x), we will use  a vertical stretch by a factor of 2, which results in 2f(x). Then, we shift the graph 3 units upward, which results in g(x) = 2f(x) + 3.

Answer: The area of Ryan's chessboard is given as 64x^6y^8 square units.

We know that the area of a square is given by A = s^2, where A is the area and s is the side length.

To find the side length of the square, we can use the formula for the side length of a square in terms of its area, which is s = √A.

Substituting A = 64x^6y^8, we get:

s = √(64x^6y^8)

Using the properties of square roots, we can simplify this expression as follows:

s = √(2^6 * (x^2)^3 * (y^2)^4)

s = √(2^6) * √((x^2)^3) * √((y^2)^4)

s = 2^3 * x^3 * y^4

Therefore, the expression for the side length of Ryan's chessboard is 2^3 * x^3 * y^4.

The measure of BC is 110°

Semicircle is defined as a half circle formed by cutting the circle into two halves. It is formed when a line passes through the center and touches the two ends of the circle. This line is called the diameter of the circle.

line AB is the diameter of the circle and thus, AB gives a semi circle.

This means that, since angle Ina semi circle is 180°, the sum of AC and BC is 180°

therefore, 2x-30+x = 180°

3x = 180+30

3x = 210

divide both sides by 3

x = 210/3 = 70°

therefore BC = 2x-30

The vertex of the graph of this equation y = x² - x - 2 is equal to -2.25.

In this exercise, you are required to determine the vertex form of a quadratic function h(x) that is written in standard form. Mathematically, the vertex form of a quadratic equation is given by this formula:

y = a(x - h)² + k

Where:

For the given quadratic function y = x² - x - 2 in question 9, the axis of symmetry can be calculated as follows:

Axis of symmetry, Xmax = -b/2a

a) The sum of the measures of the interior angles of the regular nonagon is given by S₉ = 1260°

b) The measure of each interior angle of the regular nonagon is a = 140°

c) The measure of each exterior angle of the regular nonagon​ is b = 40°

Given data ,

Sum of the measures of the interior angles of a regular nonagon:

The Polygon Interior Angle Sum Theorem states that the sum of the measures of the interior angles of a polygon with n sides is given by the formula:

Sum of interior angles = (n - 2) * 180°

For a nonagon, which has 9 sides, we can plug in n = 9 into the formula:

Sum of interior angles = (9 - 2) * 180

Sum of interior angles = 7 * 180

Sum of interior angles = 1260°

So, the sum of the measures of the interior angles of a regular nonagon is 1260°

Measure of each interior angle of a regular nonagon:

Since a regular nonagon has 9 sides, we can divide the sum of the interior angles (which we calculated as 1260 degrees) by the number of sides to find the measure of each interior angle:

Measure of each interior angle = Sum of interior angles / Number of sides

Measure of each interior angle = 1260 / 9

Measure of each interior angle = 140°

So, the measure of each interior angle of a regular nonagon is 140°

Measure of each exterior angle of a regular nonagon:

The Polygon Exterior Angle Sum Theorem states that the sum of the measures of the exterior angles of a polygon with n sides is always 360°

Since a regular nonagon has 9 sides, we can divide 360 degrees by the number of sides to find the measure of each exterior angle:

Measure of each exterior angle = 360 / Number of sides

Measure of each exterior angle = 360 / 9

Measure of each exterior angle = 40°

Hence , the measure of each exterior angle of a regular nonagon is 40°

Answer: D

Step-by-step explanation:

The given expression is 2w3 + 7w2 - 4w.

The power of the expression is the highest exponent of the variable w, which is 3. However, this is not one of the options given.

A factor of the expression is a term or expression that divides the given expression completely. -4w is not a factor of the given expression.

The coefficient of a term is the numerical factor that is multiplied by the variable. The coefficient of the first term 2w3 is 2, and the coefficient of the second term 7w2 is 7. The coefficient of the last term -4w is -4. Therefore, the statement "The coefficient of the expression is w" is false.

The given expression has three terms: 2w3, 7w2, and -4w. Therefore, the statement "The expression has 3 terms" is true.

Both the inequalities are true when we substitute x = -1 and y = 0, so (-1, 0) satisfies the system of inequalities.

An inequality expresses a relationship between two values, indicating whether one is greater than, less than, or greater than or equal to or less than or equal to the other.

To check whether the point (-1, 0) is a solution of the system of inequalities:

-7x + 3y > -1

5x - 9y > -6

We need to substitute x = -1 and y = 0 into both inequalities and check whether the resulting expressions are true or false:

-7(-1) + 3(0) > -1

==> 7 > -1 (true)

5(-1) - 9(0) > -6

==> -5 > -6 (true)

Mary's estimate of the population proportion would be more precise than Diego's.

Part A: The sample proportion (p) for Diego's data can be found by dividing the number of students who watch television shows on a computer (65) by the total number of students in the sample (100).

p = 65/100 = 0.65

Part B: To determine if the sample is large enough to calculate a confidence interval, we can use the rule of thumb that both np and n(1-p) should be greater than or equal to 10.

np = 100 * 0.65 = 65

n(1-p) = 100 * (1 - 0.65) = 100 * 0.35 = 35

Since both values are greater than or equal to 10, Diego's sample is large enough to calculate a confidence interval for the population proportion.

Part C: The standard error (SE) can be found using the formula:

SE = sqrt[p(1-p)/n]

SE = sqrt[0.65(1-0.65)/100]

SE = sqrt[0.65 * 0.35 / 100]

SE = sqrt[0.2275/100]

SE = sqrt[0.002275]

SE ≈ 0.048 (rounded to the nearest hundredth)

Part D: Using the empirical rule (68-95-99.7 rule), we can calculate the confidence intervals for Diego's sample proportion:

68% confidence interval = p ± 1 * SE = 0.65 ± 1 * 0.048 = (0.65 - 0.048, 0.65 + 0.048) = (0.602, 0.698)

95% confidence interval = p ± 2 * SE = 0.65 ± 2 * 0.048 = (0.65 - 0.096, 0.65 + 0.096) = (0.554, 0.746)

99.7% confidence interval = p ± 3 * SE = 0.65 ± 3 * 0.048 = (0.65 - 0.144, 0.65 + 0.144) = (0.506, 0.794)

Part E: Since Mary took a larger sample (200 students) compared to Diego (100 students), we would expect her 95% confidence interval to be narrower than Diego's. A larger sample size usually leads to a smaller standard error, which in turn results in a narrower confidence interval.

This means that Mary's estimate of the population proportion would be more precise than Diego's.
