2g + 4h = 43

2g + 2h = 30

Step-by-step explanation:

Answer:

pairs of gloves = x

hats = y

2x + 4y = 43

2x + 2y = 30

hats = $6.50

gloves = $8.50

Step-by-step explanation:

use the elimination method to solve this system.

subtract the first equation by the second.

2x + 4y = 43

- 2x + 2y = 30

--------------------

         2y = 13

y = 6.5

plug in the y value to find x

2x + 4 (6.5) = 43

2x + 26 = 43

2x = 17

x = 8.5

Dion's study suffers from selection bias as his sample of individuals on the beach in Miami may not be representative of the entire population's affinity for warm weather.

This is because he is only sampling residents of Miami, Florida, who are on the beach.

This group may not accurately represent the entire population's affinity for warm weather, as it excludes those who may not enjoy the beach or may not have the opportunity to visit the beach.

A more representative sample would include individuals from various locations and backgrounds to better assess the affinity for warm weather across the population.

The probability of picking a card less than 7 from a standard deck of cards is 2/13.

To find the probability (P) of picking a card less than 7, we need to determine the number of favorable outcomes (cards less than 7) and divide it by the total number of possible outcomes.

In this case, the favorable outcomes are the cards with values less than 7, which are 5 and 6. The total number of possible outcomes is the total number of cards in the deck, which depends on the specific deck being used.

Assuming a standard deck of 52 cards, there are four 5s and four 6s, making a total of eight favorable outcomes.

Therefore, P(less than 7) = favorable outcomes / total outcomes = 8 / 52.

Simplifying the fraction, we find that P(less than 7) = 2 / 13.

The required answer is  the strip of sheet metal 13 31 inches long.

To determine how many pieces 15/16 inch long can be cut from a strip of sheet metal 13 31 inches long, follow these steps:
1. Convert the mixed number 13 31 inches to an improper fraction:
  (13 * 32) + 31 = 447 inches

2. Divide the total length of the strip (447 inches) by the length of each piece (15/16 inches):
  447 inches ÷ (15/16 inches) = 447/1 * 16/15 = (447 * 16) / 15
We need to first convert the length of the sheet metal to the same unit as the length of the pieces we want to cut. Since both are in inches, we can proceed with the calculation. To calculate the number of pieces that can be cut, we need to divide the length of the sheet metal by the length of each piece.
3. Perform the multiplication and division:
  (447 * 16) = 7152
  7152 ÷ 15 ≈ 476.8

Since you can't have a fraction of a piece, you can only cut 476 whole pieces of 15/16 inch long from the strip of sheet metal 13 31 inches long.

The two inequalities representing the qualifying times for men and women in the Olympic marathon trials are:

m ≤ 138 (for men)
w ≤ 163 (for women)

To qualify for the Olympic marathon trials, the men's and women's times must be less than or equal to their respective qualifying times. So we'll write two inequalities:

1. For men (m): To qualify, they must run 2 hours and 18 minutes or faster. We'll convert this time to minutes: (2 hours * 60 minutes) + 18 minutes = 138 minutes. The inequality representing the men's qualifying times is:

m ≤ 138

2. For women (w): To qualify, they must run 2 hours and 43 minutes or faster. We'll convert this time to minutes as well: (2 hours * 60 minutes) + 43 minutes = 163 minutes. The inequality representing the women's qualifying times is:

w ≤ 163

The three conditions for a function to be continuous at a point x=a are:

a) The function is defined at x=a.

b) The limit of the function as x approaches a exists.

c) The limit of the function as x approaches a is equal to the value of the function at x=a.

The continuity of a function can be analyzed by observing its graph. However, as the graph is not provided, a specific discussion about its continuity cannot be made without further information. It is necessary to examine the behavior of the function around the point in question and determine if the three conditions for continuity are satisfied.

The function f(x) = { *** is not defined in the question. In order to discuss its continuity, the function needs to be provided or described. Without the specific form of the function, it is impossible to analyze its continuity. Different functions can exhibit different behaviors with respect to continuity, so additional information is required to determine whether or not the function is continuous at a particular point or interval.

The probability that he has exactly 7 hits in his next 7 at bats is  0.0106%.

To find the probability that a baseball player with a batting average of 0.31 gets exactly 7 hits in his next 7 at-bats, we can use the binomial distribution formula:

P(X=k) = (n choose k) * \(p^{k}\) * \((1-p)^{n-k}\)

where:

P(X=k) is the probability of getting k hits in 7 at-bats

n is the number of trials (in this case, 7 at-bats)

k is the number of successes (in this case, 7 hits)

p is the probability of success on a single trial (in this case, the batting average of 0.31)

(n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

Using this formula, we can calculate the probability as follows:

P(X=7) = (7 choose 7) * \(0.31^{7}\) * \((1-0.31)^{7-7}\)

P(X=7) = 1 * \(0.31^{7}\)* \(0.69^{0}\)

P(X=7) = 0.000106288

Therefore, the probability that the baseball player with a batting average of 0.31 gets exactly 7 hits in his next 7 at-bats is approximately 0.000106 or 0.0106%.

Without a diagram provided in the question, it is difficult to determine the angle measurement of m∠CED. However, we can use some general principles of geometry to provide a more general answer.

One principle that may be useful is the Angle Sum Property of Triangles, which states that the sum of the angles in a triangle is always 180 degrees. If we know the measures of two of the angles in a triangle, we can use this property to find the measure of the third angle.

Another principle that may be useful is the Vertical Angle Theorem, which states that vertical angles are always congruent. If we know the measure of one of the vertical angles, we can use this property to find the measure of the other vertical angle.

Alternatively, if a diagram is provided, we can use the given information to determine the measure of m∠CED. In a diagram, m∠CED could refer to an angle formed by two intersecting lines, a triangle, or any other geometric figure.

The angle measure of m∠CED could be labeled directly on the diagram, or we could use other known angles and geometric properties to find its measure.

In general, the process for finding the measure of an angle depends on the given information and the type of figure in question. By using relevant geometric principles and information, we can work towards finding the measure of an angle or any other unknown quantity in a given problem.

A vector is a mathematical object that represents both magnitude and direction.  The x-component of the vector is approximately -8.8774 m.

The x-component of a vector refers to the magnitude of the vector in the horizontal direction.

To find the x-component of a vector, we can use trigonometry.

In this case, we have a vector that is 14.4 m long and points in a 133 degree direction. To find the x-component, we need to find the horizontal projection of the vector.

To do this, we can use the cosine function. The cosine of an angle gives us the ratio of the adjacent side to the hypotenuse in a right triangle. In this case, the adjacent side represents the x-component and the hypotenuse represents the magnitude of the vector.

Using the given information, we can calculate the x-component as follows:

x-component = magnitude of the vector * cosine(angle)

x-component = 14.4 m * cosine(133 degrees)

Now, let's calculate the x-component:

x-component = 14.4 m * (-0.6176)  (rounding to four decimal places)

x-component ≈ -8.8774 m

Therefore, the x-component of the vector is approximately -8.8774 m.

The fourth graph represents the function.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A relation is a function if it has only One y-value for each x-value.

In the given graphs, the graph which represents the functions is the graph in which there is only one y value for the x value.

For each input there should be only one output.

In graph (1), the x value is same but the y values are changing which is not a function.

In graph (2), each x value has two different outputs so it it is not a function.

In fourth graph the x values are different but the y values are same, so it is a function.

Step-by-step explanation:

A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides. The diagonals of a kite are perpendicular to each other.

To prove that quadrilateral ADBC is a kite, the diagonals of the kite have to be perpendicular to each other.

AD ⊥ BC.

Since adjacent sides are equal to each other, hence:

BC = BD, AC = AD

The coordinate of the vertices are A(11, 0), B(11, 26), C(0, 18) and D(22, 18)

\(BC=\sqrt{(0-11)^2+(18-26)^2} =13.6\ unit\\\\AC=\sqrt{(0-11)^2+(18-0)^2} =21.1\ unit\)

BC = BD, AC = AD

Perimeter of kite = BC + BD + AC + AD = 2BC + 2AC = 2(13.6) + 2(21.1) = 69.4 units = 69.4 inches
