The best-hitting team can be calculated by finding the mean of each team's hitting percentages. To do this, add the ten numbers for each team and divide by 10.

Team 1: (0.345 + 0.254 + 0.278 + 0.331 + 0.267 + 0.465 + 0.189 + 0.312 + 0.365 + 0.287) / 10 = 0.3125

Team 2: (0.243 + 0.378 + 0.312 + 0.298 + 0.287 + 0.387 + 0.301 + 0.412 + 0.254 + 0.342) / 10 = 0.3267

Team 2 has the highest mean, so it is the best-hitting team.

In this example, it was determined that Team 2 was the best-hitting team by finding the mean of each team's hitting percentages. The mean of Team 1's hitting percentages was 0.3125, and the mean of Team 2's hitting percentages was 0.3267. Since Team 2 had the highest mean, it was determined to be the best-hitting team.

The best-hitting team can be calculated by finding the mean of each team's hitting percentages. To do this, add the ten numbers for each team and divide by 10.

The equations are 100x + 80y = 25600 and 50x + 160y = 18200.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Let x be the cost of a quail and y be the cost of a rabbit bought by the business lady.

Given that a business lady bought 100 quails and 80 rabbits for sh 25600.

100x + 80y = 25600

If she bought twice as many rabbits, number of rabbits = 80 × 2 = 160.

If she bought half as many quails, number of quails = 100/2 = 50

The equation is then,

50x + 160y = 25600 - 7400

50x + 160y = 18200

Hence the equations formed here at two situations are 100x + 80y = 25600 and 50x + 160y = 18200.

Although the original European immigrants were Swedes and Dutch, William Penn, a Quaker, gave the state of Pennsylvania its name in honor of his father by combining the name Penn with the Latin word Sylvania, which means "woodlands," to create "Penn's woodlands." Pennsylvania, also known as the "Keystone State," is one of the original 13 colonies (it entered the Union in 1787). The state is now dominated by two large cities: Pittsburgh, a bustling inland river port, and Philadelphia, the city of the Liberty Bell, Constitution Hall, and a vibrant metropolitan area.

Event A: "at least one die is a 3" is not mutually exclusive with Event B: "at least one die is a 6" or Event C: "the sum is 11"

Event A and Event B are mutually exclusive because when one of the die is a 6, the other die cannot be a 3 and vice versa.

Event A and Event C are not mutually exclusive because there are some outcomes where at least one die is a 3 and the sum is 11. For example (3,8), (4,7) and (6,5) are all outcomes where at least one die is 3 and the sum is 11.

Event B and Event C are not mutually exclusive because there are outcomes where at least one die is a 6 and the sum is 11. For example (5,6) and (6,5) are both outcomes where at least one die is a 6 and the sum is 11.

The probability of rolling an even number on an unfair die is 0.65, which means that if you roll the die multiple times, the proportion of times that you roll an even number will be close to 0.65.

So, the probability of rolling an even number is closest to option c) 0.65

A die is a cube with numbers on each face that are used in games or gambling. A fair die is a die that is equally likely to land on any of its faces, meaning that each face has a probability of 1/6 of being the face that lands up. An unfair die is a die that does not have an equal probability of landing on each face. It means that the probability of landing on each face is not the same.

In the given scenario, it is said that the probability of rolling an even number on an unfair die is 0.65. This means that if you roll the die multiple times, the proportion of times that you roll an even number will be close to 0.65. It means that the die is not fair, and it is more likely to roll an even number.

What is the Linear equation?

An algebraic equation with only a constant and a first-order (linear) term is said to be linear if it has the formula y = mx + b, where m is the slope and b is the y-intercept. The above is occasionally referred to as a "linear equation with two variables," where y and x are the variables.

y = mx + c

where m denotes the slope.

The y-intercept is represented by the constant c. (Where x is zero)

In our instance, y-intercept equals 60.

The line's equation will therefore be:

y = mx + 60

y = mx + 60

There are given the line's coordinates (4, 90). These considerations will thus satisfy the equation.

90 = 4*m + 60

4.m = 30 m = 7.5 m = 7.5 y = 7.5x + 60 y = 7.5 * 6 + 60 y = 45 + 60 y = 105 is

y = 7.5x + 60.

If Adam's study for 6 hours then his score would be

y = 7.5x + 60.

y = 7.5(6) + 60

y = 105

Hence,

The dealerships will each have sold 23 cars in 1 day.

The first step is to form a linear equation that represents the number of cars that are sold by the dealerships. A linear equation is an equation that has a single variable that is raised to the power of one.

The form of a linear equation that represents the total cars sold by the dealership is:

Total cars sold = cars already sold + (number of cars sold per day x number of days)

Total cars sold by Clarksville Cars= 15 + (8 x d)

= 15 + 8d

Total cars sold by Robinson's Autos = 13 + (10 x d)

= 13 + 10d

When the two dealerships are tied, the two above functions would be equal:

13 + 10d= 15 + 8d

In order to determine the value of d, take the following steps:

Combine and add similar terms:

10d - 8d = 15 - 13

2d = 2

Divide both sides of the equation by 2

d = 2 / 2

47 square centimeters is equal to 303.225 square inches.

Measure the length and width of an object, such as a rectangle, and multiply the results to get the number in square centimeters. In the event that the length and width are 15 cm and 10 cm, respectively, the formula is 15 cm*10 cm, which equals 150 cm2.

Any number that is multiplied by itself is transformed into a square. A different word for this is a number squared. The symbol for "squared" is 22 since 2 x 2 equals 4.

In mathematics, the squared sign (2), an arithmetic operator, stands in for multiplying an integer by itself. The "square" of an integer is the sum of that number and itself. Therefore, 10,000 square meters are represented by one square centimeter.

Angular speed is the time rate at which an object rotates, or revolves, about an axis, or at which the angular displacement between two bodies changes. In the figure, this displacement is represented by the angle θ between a line on one body and a line on the other.

The relationship between angular and linear speed is v = wr

where w= angular speed

v = linear speed

and r is the radius

1 inch = 1.578×10^-5

r = 32/2 = 16 inches = 16×1.578×10^-5

Ridge regression is a type of linear regression used to reduce the effects of multi-collinearity. It is used with 1000 labeled examples to minimize the sum of the squared errors of the model.

Ridge regression is a type of linear regression used to reduce the effects of multi-collinearity. It adds a penalty term to the cost function that penalizes large coefficients, thus reducing their magnitude. The penalty term is a regularization term that is added to the cost function to minimize overfitting. To use ridge regression, one must select a value for the regularization parameter. This parameter determines how much the model weights the penalty term, and is usually determined through cross-validation. With 1000 labeled examples, ridge regression can be used to minimize the sum of the squared errors of the model. The model is then trained on the data, and predictions can be made. Ridge regression is a powerful tool for reducing the effects of multi-collinearity, and can be used to accurately model relationships between variables.

A person can see a distance of approximately 32.9 miles on a clear day from a height of 1461 feet above the given planet.

d = 2 √(hR)

We can use the formula d = 2 √(hR) to calculate the distance d to the horizon that a person can see on a clear day from a 1461 feet above the given planet.

First, we need to convert the height of 1461 feet to miles. We can use the conversion factor of 1 mile = 5280 feet. Therefore, the height h = 1461/5280 ≈ 0.2772 miles.

Next, we need to find the radius of the planet. The radius of the planet is given as 3900 miles.

Finally, we can substitute h = 0.2772 miles and R = 3900 miles into the formula d = 2 √(hR).

d = 2 √(0.2772*3900) = 2 √(1083.08) ≈ 32.9 miles
