    Based on the graph above, in how many of the games played did the soccer team score goals equal to the median number of goals for the 29 games?

    The sum of all values across the observations divided by the overall sample size is the mean of the set of observations.
    The value of the specified number of observations that divides it into two parts is its median. Therefore, based on the proportion of even or odd observations, it is possible to calculate the median of ungrouped data when the data are arranged in descending or ascending order.
    The observational value with the highest frequency is the mode.
    Data mean sum of all observations divided by the total number of observations.

    If y = 3x2 + 6x + 2  is graphed in the xy-plane, which of the following characteristics of the graph is displayed as a constant or coefficient in the equation?

    A linear equation is a two-variable equation with a line as the graph. A collection of points in the coordinate plane that are all solutions to the equation make up the graph of the linear equation. If every variable has a real value, the equation can be graphed by placing enough points on the graph to identify a pattern, then connecting those points to include all of the points.
    Try to include zero as well as both positive and negative numbers when selecting your points. The two locations where the graph crosses the axes can be used if you want to utilize two points to draw your line. The x-intercept and y-intercept of a graph are the points where the axes cross, respectively. The value of x can be determined when y = 0 (x, 0) yields the x-intercept, and similarly, determining the value of y when x = 0 yields the y-intercept (0, y).

    h(x) = −16x2 + 100x + 10
    The quadratic function above models the height above the ground h, in feet, of a projectile x seconds after it had been launched vertically. If y = h(x) is graphed in the xy-plane, which of the following represents the real-life meaning of the positive x-intercept of the graph?

    Quadratic equations typically have two solutions because the solutions are where the parabola intersects the x-axis. The graph will cross twice if the vertex is below the x-axis and the parabola opens up, and twice if the vertex is above the x-axis and the parabola opens down.
    Quadratic equation graphing to create a parabola graph, we must first determine the vertex of the given equation. This is possible by using x = -b/2a and y = f(-b/2a). The graph is plotted when the quadratic equation is given in the form f(x) = a(x-h)2 + k, where (h, k) is the vertex of the parabola.

    Near the end of a US cable news show, the host invited viewers to respond to a poll on the show’s website that asked, “Do you support the new federal policy discussed during the show?” At the end of the show, the host reported that 28% responded “Yes,” and 70% responded “No.” Which of the following best explains why the results are unlikely to represent the sentiments of the population of the United States?

    Those who responded to the pool were not a random sample of the population of the United States. Moreover, because the people were watching a US cable news show, it could not have been very objective. Thus the majority of those watching it shared the same political bias. Therefore, the program's viewers might need to accurately represent the entire American populace.
    Getting highly responsive is not something that has any percentage of yes or no responses because what we're trying to find out is how people feel about it. So having 50-50 people is not a condition that the show needed to allow more time to respond to the information. So we need to know the time taken to respond to the pool and what percentage of people were at a discount.

    The weights, in pounds, for 15 horses in a stable were reported, and the mean, median, range, and standard deviation for the data were found. The horse with the lowest reported weight was found to actually weigh 10 pounds less than its reported weight. What value remains unchanged if the four values are reported using the corrected weight?

    The standard deviation is the degree of scatter or dispersion of the data points to their mean in descriptive statistics.
    It provides information on the distribution of values within the data sample and verifies how widely apart the data points are from the mean.
    A square root of the variance of a sample, statistical population, random variable, data collection, or probability distribution represents its standard deviation.
    How to Calculate Standard Deviation
    1.) Discover the observations' mean and arithmetic mean.
    2.) Find the squared deviations from the mean. (The data value - mean) 2
    3.) Calculate the squared difference average. (Variance = The total squared differences divided by the total number of observations)
    4.) Determine the variance's square root. (Standard deviation = Square root of variance)
