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.

At point 1, Tia began filling the bathtub at a constant rate until the water in the bathtub reached point 2
She then turned off (point 2) the water for a while and some of the water drained out of the bathtub. That, the water level dropped from point 2 to point 3
Tia turned the water back on(point 3) at the same rate as before until the bathtub was full (point 4). As you can see there is an increase from point 3 to point 4.

How do you find the domain and range of a graph equation and table?
The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph indicates the available expected output, or range of graph.
In the given question, we have to explain how we can find the domain and range of a graph equation and table.
The domain and range are typically listed in a table's left and right columns, respectively. In a relation or function, the domain can alternatively be thought of as the input values (x), and the range as the output values (y).
Graphs can be used as another tool for determining the domain and range of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values.

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.

A parabola is a curve whose equation has a point on it that is equally spaced from both a fixed point and a fixed line. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix).

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.

How can the triangles be proven similar by the SSS?
Answer:If the corresponding sides are known then they can be calculated.
Step-by-step explanation:If the measures of corresponding sides are known, then their proportionality can be calculated.
Directions: Use the formula Sn =a (1 - rn ) ÷ (1 – r) to find the sum Sn for each of the geometric series, given the value for a, r, and n.
1. a = -1, r = -2, n = 8
2. a = ½, r = -1/3, n = 6
3. a = 4, r = 3, n = 5
4. a = -9, r = -3, n =4
5. a = 6, r = 3, n =4
6. a = 4, r = ¼, n = 4
7. a = 3, r = -2, n = 7
8. a = -2, r = 3, n = 5
The required sum Sn for each of the given geometric series is illustrated in the solution.
The sum of a geometric series is given by the formula Sn = a(1 - r^n) / (1 - r), where a is the first term of the series, r is the common ratio, and n is the number of terms in the series.
As per the given question, the required solution would be as:
1. a = -1, r = -2, n = 8:
Sn = (-1)(1 + 2⁸) / (1 + 2) = -1023 / 3
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:
Sn = (-9)(1 + (-3)⁴) / (1 + (-3)) = -729 / 2
5. a = 6, r = 3, n = 4:
Sn = (6)(1 + 3⁴) / (1 + 3) = 3456 / 4
6. a = 4, r = 1/4, n = 4:
Sn = (4)(1 + (1/4)⁴) / (1 + (1/4)) = 256 / 5
7. a = 3, r = -2, n = 7:
Sn = (3)(1 + (-2)⁷) / (1 + (-2)) = -769 / 3
8. a = -2, r = 3, n = 5:
Sn = (-2)(1 + 3⁵) / (1 + 3) = -1792 / 4

The slope of the line through − 7 − 2 and − 6 7 is 9. A line's steepness can be determined by looking at its slope.
Where y and x denote the first and second values, respectively, and y and x2 denote the third and fourth values, respectively, and m is the slope
I by itself would result in m in our scenario.
m= y2 - y/x2 - x
Since x and y are random positions, I will state that the first point, X, is at (-7, -2) and the second point, Y, is at (-6, 7). Therefore, we will enter the values below in their place:

The machine discharge more than 7.0 oz or does the difference represent chance variation is 0.0274
What is meant by variation?
In math, variance refers any difference between the individuals in a species or groups of organisms of any species.
Here we have given that a coin-operated soft drink machine was designed to discharge, on average, 7 oz of beverage per cup. in a test of the machine, 10 cupful's of beverage were drawn from the machine and measured. the average and SD of the ten measurements were 7.1 oz and 0.12 oz, respectively. assume that the histogram of beverage discharge from this machine roughly follows a normal curve.
And we need to find machine discharge more than 7.0 oz or does the difference represent chance variation.
By using the Applet, to find the exact p-value we first need to find P(Z≥2.63) where Z is a t9 random variable.
=> P(Z≥2.63)=0.0137
=> 2×P(Z≥2.63)=0.0274
