What would the equation be if my coordinates were, (-4,3) (2,6) ?

A population has a mean μ=135 and a standard deviation Ï=28.

The mean of the sampling distribution of sample means is equal to the population mean, that is 135.

The standard deviation of the sampling distribution of sample means can be calculated by using the formula

SE = Ï /\(\sqrt{n}\)

Where Ï is the population standard deviation and n is the sample size.

By putting the given values we get

SE = 28 / \(\sqrt{57}\) = 3.7

Hence, the mean of the sampling distribution of sample means is 135, and the standard deviation is 3.7.

Based on the provided information of speed, A) Beth gets to San Francisco first. B) The first to arrive has to wait for 20 minutes for the second to arrive.

A) To find out who gets to San Francisco first, we need to calculate the time it takes for each of them to travel the distance of 400 miles.

For Brian, we use the formula time = distance / speed:

time = 400 miles / 50 mph = 8 hours

So Brian will arrive in San Francisco at 4:00 p.m. (8:00 a.m. + 8 hours).

For Beth, we use the same formula:

time = 400 miles / 60 mph = 6.67 hours

So Beth will arrive in San Francisco at 3:40 p.m. (9:00 a.m. + 6.67 hours).

Therefore, Beth gets to San Francisco first.

B) To find out how long the first to arrive has to wait for the second, we subtract the arrival time of the first from the arrival time of the second:

wait time = 4:00 p.m. - 3:40 p.m. = 0.33 hours = 20 minutes

So the first to arrive has to wait for 20 minutes for the second to arrive.

Note: The question is incomplete. The complete question probably is: Brian leaves Los Angeles at 8:00 a.m. to drive to San Francisco, 400 miles away. He travels at a steady speed of 50 mph. Beth leaves Los Angeles at 9:00 a.m. and drives at a steady speed of 60 mph. A) Who gets to San Francisco first? B) How long does the first to arrive have to wait for the second?

The coordinate matrix of x in Rn relative to the basis b' is [5, 6]. To find the coordinate matrix of x in Rn relative to the basis b', we need to express x as a linear combination of the basis vectors in b'.

Given the basis b' = {(9, 0), (0, 4)} and the vector x = (45, 24), we want to find the scalars c1 and c2 such that:

x = c1*(9, 0) + c2*(0, 4)

By solving this equation, we can determine the values of c1 and c2, which represent the coordinates of x in the basis b'.

Expanding the equation, we have:

(45, 24) = (9c1, 0) + (0, 4c2)

Equating the corresponding components, we get two equations:

45 = 9c1   (equation 1)

24 = 4c2    (equation 2)

Solving equation 1, we find c1 = 5.

Solving equation 2, we find c2 = 6.

Therefore, the coordinate matrix of x in Rn relative to the basis b' is [5, 6].

In other words, the vector x can be expressed as a linear combination of the basis vectors in b' with coefficients 5 and 6, respectively.

The total surface area of a cube is given by the formula 6s^2, where s is the length of each side of the cube. In this case, the total surface area is given as 60 square centimeters. Therefore, we can set up the equation:

6s^2 = 60.

Dividing both sides by 6, we get:

s^2 = 10.

Taking the square root of both sides, we have:

s = √10.

The volume of a cube is given by the formula s^3. Substituting the value of s, we get:

Volume = (√10)^3 = 10√10.

Hence, the volume of the cube is 10√10 cubic centimeters, which is the final answer.

Step-by-step explanation:

If the two angles are equal to each other, then lines u and v are parallel.

So set those 2 angles equal to each other, solve for x.

25x = 127-2

25x = 125

x = 5

So if x = 5, then lines u and v are parallel.

What is Set ?

In mathematics, a set is a collection of distinct objects, called elements, that are grouped together based on some common characteristic or property. Sets are denoted using braces { } and listing the elements inside the braces, separated by commas. For example, the set of even numbers less than 10 can be denoted as {2, 4, 6, 8}.

Sets can be finite, meaning they have a fixed number of elements, or infinite, meaning they have an infinite number of elements. Sets can also be empty, meaning they have no elements.

Two sets are considered equal if they have the same elements. For example, the sets {1, 2, 3} and {3, 2, 1} are equal, even though they list the elements in a different order.

Sets can be manipulated using set operations, such as union, intersection, and complement. The union of two sets A and B, denoted by A ∪ B, is the set that contains all the elements that are in A, in B, or in both. The intersection of two sets A and B, denoted by A ∩ B, is the set that contains all the elements that are in both A and B. The complement of a set A, denoted by A', is the set that contains all the elements that are not in A.

To solve this problem, we need to use the principle of inclusion-exclusion, which allows us to count the number of kids who participate in at least one of the sports.

Let A be the set of kids who sign up for basketball, B be the set of kids who sign up for softball, and C be the set of kids who sign up for swimming. Then we can use the following formula to count the number of kids who participate in at least one of the sports:

|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|

where |X| represents the number of elements in the set X.

Substituting the given values, we get:

|A ∪ B ∪ C| = 14046 + 16596 + 17354 - 7923 - 6790 - 10001 + 4119

Simplifying the equation gives:

|A ∪ B ∪ C| = 32501

The equation that describes the relationship between the time a zebra runs at a speed and the distance it covers is y = 2/3(x).

A linear equation is an algebraic equation of the form y=mx+b. where m is the slope and b is the y-intercept.

Assuming that the relationship between the time a zebra runs at a speed and the distance it covers is a linear one, we can use the formula for the equation of a straight line:

y = mx + b

where y is the distance covered, x is the time the zebra runs at a speed, m is the slope (i.e., the speed of the zebra), and b is the y-intercept (i.e., the distance covered when the zebra is not running).

From the table two points can be formed as (x, y) that are, (3, 2) and (6, 4)

Using these two points, we can find the slope of the line:

m = (y₂ - y₁)/(x₂ - x₁)

 = (4 - 2)/(6 - 3)

 = 2/3

Now as we have the slope m we can use it in point slope form, i.e.

y - y₁ = m(x - x₁)

Using the point (3, 2),

y - 2 = 2/3(x - 3)

y - 2 = 2/3(x) - 2

y  = 2/3(x) - 2 + 2

y  = 2/3(x)

Hence, the equation that describes the relationship between the time a zebra runs at maximum speed and the distance it covers is:

y  = 2/3(x)

Answer:

g. 92*

h. 88*

m. 89*

k. 91*

Step-by-step explanation:

To find h and m: All of the angles on a straight line added up equals 180*. So if there are two angles, the sum of them must equal 180* (angle A + angle B = 180*)

So in this case we have angle h + 92* = 180* using algebra, we subtract 92 from both sides and we get angle h = 88*

If you want to check, add 92 + 88 = 180.

Also angle m + 91* = 180*. Same thing as above, subtract 91 from both sides and we get angle m = 89*

If you want to check, add 91 + 89 = 180.

When you have two straight lines intersecting (crossing), the opposing angles at that crossing are going to be equal. So in this case angle g is opposite from the anbgle that we know is 92*, so angle g is also 92*. Same thing for angle k, we know the angle opposite angle k is 91*, so we know that angle k is also 91*.

The question is wrong because as the given angle is 90, the hypotenuse(11cm) should be greater than 16cm

Answer:

(sorry im not good at english) because there is no right triagle in which the length of the side of the right angle is greater than the length of the hypotenuse.

The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²

The standard equation of a circle is given by:

Where (h, k) is the center of the circle and r is the radius.

Given that diameter = 15 miles, hence radius = 15/2  = 7.5. Also, center = (80, 26)

The equation of circle is:

(x - 80)² + (y - 26)² = 7.5²

The marginal cost will most likely increase to $2.00

Marginal cost is the change in the production costs that would be required to make one extra unit of production.

The marginal costs will continue to rise, increasing the total cost, while the marginal revenue remains the same, decreasing the profit.

For example, if a company produces a cup for $5, and 10 cups would be $50, therefore, the marginal cost is the extra cost it would take to manufacture an additional cup.
