a baseball league has nine teams. during the season, each of the nine teams plays exactly three games with each of the other teams. what is the total number of games played?
The total number of game played are 108.
What is baseball?
In the bat-and-ball game of baseball, two teams of nine players each alternate between batting and fielding. When the umpire indicates to the pitcher that the ball is now in play, either verbally or physically, the game is in progress.
9 teams means each team will play 8 other teams 3 times (totaling 24). 24 games times 9 teams is 216.
However, when you count the first 24 games for team 1, you are counting the 3 games played against team 2.
When you add the games for team 2, you can’t also add the games played against team 1, or you’d be doubling the games counted.
This continues for each team. Team 3 can’t count it’s games against teams 1 or 2. Team 4 can’t count it’s games against teams 1, 2, or 3.
Continuing this and adding the total gets you 108.
Also, taking the first total of 216, you can simply divide by 2 and get the same number.
Hence, the total number of game played are 108.

how is the amount of variability between groups quantified? group of answer choices comparing the standard deviations of each group to each other comparing the sample means of each group to each other. comparing the sample means of each group to the grand mean comparing the standard deviations of each group to the grand standard deviation
The amount of variability between groups quantified is group of answer choices comparing the standard deviations of each group to each other comparing the sample means of each group to each other.
A variability measure is a summary statistic that describes the amount of variation in a dataset. Central tendency measures describe typical values, while variability measures define how far away data points tend to be from the center. We talk about variability in the context of value distribution. A small variance indicates that the data points tend to be clustered near the center. A large spread means they tend to move further apart.
Analysts often use averages to summarize the center of a population or process. Averages are good, but people are often more sensitive to fluctuations. The less variability in the distribution, the more consistent the values within the dataset. However, the higher the variability, the more diverse the data points and the more likely extreme values will occur. Therefore, understanding variability helps us to understand the likelihood of anomalous events.
Meteorologists have seen weather forecasts showing extreme heat and drought in some areas and flooding in others. We often feel more uncomfortable in the extreme than in the middle. Understanding this variability about the mean provides important information.

We know that the value in mathematics is nothing but the worth of each digit depending on where it lies in the number.
We calculate the value of number by multiplying the place value and face value of the digit.
The value formula is:
Value = Place Value × Face Value
Place value is the value of the column in which the number is. Each column in a number holds a different place value.
For exa., consider a number 456. Here, the place value of the digit 5 is tens and the place value of 4 is hundreds.

2. a = 1/2, r = -1/3, n = 6:
Sn = (1/2)(1 + (-1/3)⁶) / (1 + (-1/3)) = (1/2)(1 + 1/729) / (4/3) = 728/2187
3. a = 4, r = 3, n = 5:
Sn = (4)(1 + 3⁵) / (1 + 3) = 1792 / 4
4. a = -9, r = -3, n = 4:

A system of a linear equation is said tk be consistent if it had at least one solution ? true false​
A system of a linear equation is said tk be consistent if it had at least one solution is true
In a linear equation, the largest power of the variable is always equal to 1. It's also known as a one-degree equation. Typically, Ax + B = 0 is used to represent a linear equation with one variable. The variables x, A, and B in this case serve as constants and coefficients, respectively. The typical form of a linear equation with two variables is Ax + By = C. Here, x and y are the variables, A and B are the coefficients, and C is the constant. If there is at least one solution, a set of linear equations is considered to be consistent. This means that when all equations in the system are solved, at least one set of values for the variables can be found which satisfy all equations simultaneously. So, the statement is true.

To draw a figure with 1 : 1 scale, draw the the figure in actual size
The scale factor can be defined as the ratio between the original size of the figure and the new size of the figure.
While scale factoring the shape of the object will be same but the size changes
Here the given ratio = 1 : 1
The means the scale factor = 1/1
= 1
When the scale factor is equal to one, the the size of the original object and the size of the new object will be same
Therefore, 1 : 1 scale bar is the drawing with actual size of the object

What does 1/2 of a number mean?
1/2 of a number means one - half of a number.
The irreducible fraction that results from dividing one by two or from dividing any number by its double is known as a half (plural: halves).
Conversely, division by one-half is equivalent to multiplication by two, or "doubling," while multiplying by one-half is equivalent to division by two, or "halving."
In measurements, recipes, equations, etc., one half is frequently used. One part of something that is divided into two equal pieces is said to be divided in half.
For instance, a triangle's S-area is calculated.
S = base / 2 * perpendicular height.

how many integers must you pick in order to be sure that at least two of them have the same remainder when divided by 14?
Because of this, we need to choose 15 integers in such a way that we can ensure that when they are divided by 14, at least two of them will provide the same residual.
In order to be sure that at least two of them have the same remainder when divided by 14.
Generally, If you divide a number by 14, the result is a fraction. There are 14 remainders that might occur, and they are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and, 13.
So if we pick a number and divide it by 14, the remainder can be one of 14 (0 memory 13). So if we select 14 numbers, we have the option to select 14 unique memories ranging from 0 to 13.
Finally, if we choose another integer, we will have the same reminders according to the drawer principle, because there are only 14 reminders and 15 > 14.
Therefore, we should choose the number of 15 so that at least two numbers have the same remainder when divided by 14.
