Provide your answer below:

Answer:

Step-by-step explanation:

We can use the Central Limit Theorem to approximate the distribution of the sample mean. Since the sample size is large (n=61), the sample mean will be approximately normally distributed with mean μ = 2.6 feet and standard deviation σ/√n = 0.4/√61 = 0.0517 feet.

To find the probability that the sample mean is less than 2.2 feet, we standardize the sample mean as follows:

z = (x - μ) / (σ/√n) = (2.2 - 2.6) / (0.4/√61) = -3.692

We look up the probability corresponding to z = -3.692 in the standard normal distribution table or use a calculator to find the area under the standard normal curve to the left of z:

P(z < -3.692) ≈ 0.0001 (rounded to 4 decimal places)

Therefore, the probability that the mean of the sample taken is less than 2.2 feet is approximately 0.0001.

Using the given information, Thursday game generates $2240.00 and Saturday game generates $2413.00.

How much money did Thursday game generate? $2240.00

How much money did Saturday game generate? $2413.00

From the question, we are to determine how much money was taken in at each game.

From the given information, the two games together earn $4653.00 for the team.

Thursday game generates $173.00 less than Saturday's game

Let T represent Thursday game and S represent Saturday game.

Then,

We can write the equations

T + S = $4653.00       --------- (1)

S - T = $173.00           --------- (2)

From the second equation, we can write that

S = $173.00 + T          --------- (3)

Substitute into the first equation

T + S = $4653.00

T + $173.00 + T = $4653.00

2T = $4653.00 - $173.00

2T = $4480

T = $4480/2

T = $2240.00

Substitute into the third equation

S = $173.00 + T

S = $173.00 + $2240.00

S = $2413.00

Hence, Thursday game generates $2240.00 and Saturday game generates $2413.00

The mean is 0.477514 (rounded to 6 decimal places).

The standard deviation is 0.288919 (rounded to 6 decimal places).

To calculate the mean and standard deviation, we will use the following formulas:

Mean = (sum of all values) / (number of values)

Standard deviation = sqrt[(sum of (value - mean)^2) / (number of values)]

Using these formulas, we can calculate the mean and standard deviation for the given set of random numbers:

Mean = (0.937776 + 0.270012 + 0.243785 + 0.590701 + 0.824982 + 0.131805 + 0.879337 + 0.741998 + 0.254683 + 0.080259 + 0.419321 + 0.928220 + 0.958430 + 0.980182 + 0.263900 + 0.063119 + 0.762096 + 0.485612 + 0.662900 + 0.362242 + 0.724796 + 0.307736 + 0.305021 + 0.417052 + 0.054337 + 0.323357 + 0.069662 + 0.843387 + 0.353107 + 0.074262 + 0.735596 + 0.175095 + 0.390508 + 0.668932 + 0.029861 + 0.205228 + 0.387740 + 0.962169 + 0.646565 + 0.423914 + 0.754782 + 0.156719 + 0.773113 + 0.546335 + 0.323573 + 0.649740 + 0.214082 + 0.382383 + 0.383982 + 0.030539) / 50 = 0.477514

Answer:

The mean of the sample distribution of the sample mean is the same as the population mean, which is 40 dollars. The standard deviation of the sample distribution of the sample mean (also called the standard error) is given by:

standard error = standard deviation / sqrt(sample size) = 8 / sqrt(49) = 8 / 7

To find the probability that the sample mean would be less than 37.4 dollars, we need to standardize the sample mean using the standard error and then look up the probability from a standard normal distribution table. The z-score for a sample mean of 37.4 dollars is:

z = (37.4 - 40) / (8 / 7) = -1.225

Looking up this z-score in a standard normal distribution table, we find that the probability of getting a sample mean less than 37.4 dollars is 0.1103 (rounded to four decimal places). Therefore, the probability that the sample mean would be less than 37.4 dollars is 0.1103.

This project would cost $27,000 (option B) to the contractor for a building size of 900ft.

Given = 240 ft take 72 hours:

240 ft / 72 hours = 900 ft / x hours

Cross-multiplying, we get:

240 ft x x hours = 72 hours x 900 ft

x = (72 hours x 900 ft) / 240 ft

x = 270 hours

So, for a 900 ft project, it would take 270 hours of work.

The cost of the project can be found by multiplying the number of hours by the labor cost per hour:

Cost = hours x labor cost per hour

Cost = 270 hours x $100 per hour

After answering the presented question, we can conclude that Ty Cobb's performance had already peaked by 1918, and his future potential was questionable.

A mathematical equation is a formula that links two statements and uses the equals sign (=) to indicate equality. In algebra, an equation is a statement that demonstrates the equality of two mathematical expressions. The equal sign divides the variables 3x + 5 and 14 in the equation 3x + 5 = 14, for instance. The relationship between the two phrases that appear on opposing sides of a letter is explained by a mathematical formula. Frequently, the symbol and the single variable are identical. as 2x - 4 equals 2, for example.

Ty Cobb had a batting average of.382 and a slugging percentage of.521, while Babe Ruth had a batting average of.300 and a slugging percentage of.555 in 1918. It is tough to make a firm determination on whether to trade Ruth for Cobb based only on this information.

Nonetheless, given the two players' total performance and potential, it would be unwise to deal Babe Ruth for Ty Cobb. Babe Ruth was recognized for his tremendous hitting and pitching ability and would go on to become one of baseball's best players of all time, but Ty Cobb's performance had already peaked by 1918, and his future potential was questionable.

The electric company would need a wire that is approximately 4.58 meters long to reach the top of the 5-meter electric pole from a point on the ground 2 meters from the base of the pole.

What is Meter?

The meter was originally defined as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris, but this definition was later replaced by the current definition based on the speed of light.

To determine the length of the wire required to reach the top of a 5-meter electric pole from a point on the ground 2 meters from the base of the pole, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the pole, the ground, and the wire form a right triangle, where the pole is the hypotenuse, the distance from the base of the pole to the point on the ground is one of the legs, and the length of the wire needed to reach the top of the pole is the other leg.

Therefore, we can use the Pythagorean theorem to solve for the length of the wire as follows:

wire length = sqrt([tex]pole height^{2}[/tex] - [tex]distance from base^{2}[/tex])

= sqrt([tex]5^{2}[/tex] - [tex]2^{2}[/tex])

= sqrt(25 - 4)

Using one of circle theorems, the value of x in the given circle is 2

From the question, we are to determine the value of x in the given diagram

In the diagram, we have a circle that shows an arc measure of 186°.

From one of circle theorems, we have that

The angle subtended by an arc at the center of the circle is twice the angle subtended at the circumference.

From this, we can write that

186° = 2(36x + 21)

Solve the equation for x

186° = 2(36x + 21)

Divide both side by 2

186/2 = 2(36x + 21) / 2

93 = (36x + 21)

93 = 36x + 21

Subtract 21 from both sides

93 - 21 = 36x

72 = 36x

Divide both sides by 36

72 / 36 = 36x / 36

Using mathematical operations involving unit conversions, the greatest number of 16-inch pieces of wood the carpenter can cut from 8 boards is 54.

The four basic mathematical operations are multiplication, division, subtraction, and addition.

In this situation, the units are converted from feet to inches using multiplication, before the greatest number of pieces are determined using division.

The quantity of boards the carpenter wants to cut = 8 boards

The length of each board = 9 feet

The total quantity of the boards in feet = 72 feet (8 x 9)

12 inches = 1 foot

72 feet = 864 inches (72 x 12)

The length of each piece of wood = 16 inches

The greatest number of 16-inch pieces of wood = 54 pieces (864 ÷ 16)

We have shown that if two lines are parallel, then they have the same slope.

A shape is translated when it is moved up, down, left or right without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions.

We can prove that parallel lines have the same slope by using the fact that the distance between corresponding points of a figure and its translated image is the same at every point.

Suppose we have two parallel lines, line A and line B, with slopes m₁ and m₂, respectively. Let P be any point on line A, and let Q be the corresponding point on line B such that P and Q are equidistant from the line of intersection of A and B.

Now let us translate line A to a new line A', such that P is mapped to Q. Since the distance between corresponding points of A and A' is the same at every point, we know that the distance between P and the line of intersection of A and B is equal to the distance between Q and the line of intersection of A' and B.

Since A' and B are still parallel, the distance between Q and the line of intersection of A' and B is equal to the distance between any point on line B and the line of intersection of A' and B.

Therefore, the distance between P and the line of intersection of A and B is equal to the distance between any point on line B and the line of intersection of A' and B. This means that the slope of line B, m₂, must be equal to the slope of line A', which is also equal to m₁.

Hence, we have shown that if two lines are parallel, then they have the same slope.

The value of 'x' for given problem is 81 degrees.

The intersection of two lines produces vertical angles, which are pairs of angles. Consistently having the same measure, they are congruent. A pair of vertical angles is a pair of non-adjacent, opposing angles that have the same vertex but different sides.

In given Problem, we have two vertical angles:

one measures (x + 3) degrees and

other measures 84 degrees.

As a result of the congruence of vertical angles, we may construct an equation to get the value of x. 84 degrees and (x + 3) degrees are both vertical angles, hence they must be equal to one another:

To find the horizontal distance the football travels, we need to find the maximum value of the quadratic function y = -16x^2 + 85x, which occurs at the vertex of the parabola.

The x-coordinate of the vertex is given by -b/2a, where a = -16 and b = 85:

x = -b/2a = -85/(2*(-16)) = 2.66

So the football travels a horizontal distance of approximately 2.66 feet when kicked.

To check that this is the maximum distance, we can find the value of y at x = 2.66:

y = -16(2.66)^2 + 85(2.66) = 113.56

So the maximum height reached by the football is approximately 113.56 feet.

Therefore, Dario kicks the football a horizontal distance of approximately 2.66 feet.
