Fatima's claim is not supported by the table because, the distribution is skewed right, with a median of 0.4 field goal advantage.

From the table, the median position is calculated as:

\(\mathbf{Median = \frac{1}{5} th}\)

\(\mathbf{Median = 0.2\ nd }\)

The 0.2nd data falls in the 0.4 field goal category.

So, the median element is:

\(\mathbf{Median = 0.4}\)

However, the distribution of the table are concentrated on the left.

x = 118.5°

Step-by-step explanation:

the measure of the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, that is

x = \(\frac{1}{2}\) (27 + 210)° = \(\frac{1}{2}\) × 237° = 118.5°

The value of x in the given circle by secant lines is 118.5 degrees.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

A straight line that intersects a circle in two points is called a secant line

A chord is in a unique secant line and every secant line defines a unique chord.

The measure of the angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle

x=1/2(210+27)

x=1/2(237)

Divide two hundred thirty seven by two

x=118.5

Hence, the value of x in the given circle by secant lines is 118.5 degrees.

Factors considered for potential aquifers: permeability, porosity, recharge. Avoid areas near contamination or high population density.

Examining the geology of a region for potential useable aquifers involves considering various characteristics and factors. Permeability, the ability of rocks or sediments to transmit water, is a key attribute. Highly permeable formations like sandstone or limestone facilitate water movement, making them favorable for aquifer development. Porosity, the amount of empty space within rocks or sediments, indicates the storage capacity of an aquifer. High porosity allows for greater water storage.

Recharge rates, the rate at which water replenishes the aquifer, are also important. Areas with consistent and sufficient rainfall or access to water sources like rivers and lakes tend to have higher recharge rates, making them suitable for aquifer utilization.

However, it is crucial to consider natural and human factors to determine areas to avoid. Proximity to contamination sources, such as industrial activities or landfills, can pose a risk to the water quality of an aquifer. Additionally, regions with high population density often face increased demands for water, which may lead to excessive groundwater extraction, causing depletion and long-term sustainability concerns.

C. F-test statistic for testing the validity of the regression equation.

In multiple regression analysis, the ratio of MSR (Mean Square Regression) to MSE (Mean Square Error) is used to calculate the F-test statistic.

This statistic is used to test the overall validity of the regression equation, determining whether the regression model as a whole is statistically significant in explaining the variation in the dependent variable.

The F-test assesses whether the regression model as a whole provides a significant improvement over the null model (a model with no independent variables).

A large F-statistic indicates that the regression equation is statistically significant, implying that at least one of the independent variables has a significant effect on the dependent variable.

Therefore, option C, the F-test statistic for testing the validity of the regression equation, is the correct answer.

Using the areas of the rectangle and of the square, it is found that 24 unit squares will be used to tile the rectangle.

The area of a square of side l is given by the square of l, that is:

A(l) = l².

In this problem, we have that \(l = \frac{1}{10}\), hence the area is given by:

\(A = \left(\frac{1}{10}\right)^2 = \frac{1}{100} = 0.01\)

The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:

A = lw.

In this problem, we have that the measures are:

\(l = \frac{3}{10}, w = \frac{4}{5}\)

Hence:

\(A = lw = \frac{3}{10} \times \frac{4}{5} = \frac{12}{50} = \frac{24}{100} = 0.24\)

The area of the rectangle is 24 times the area of the square, hence 24 unit squares will be used to tile the rectangle.

where \(\(x\)\) is the sample mean, \(\(\mu\)\) is the population mean under the null hypothesis, s is the sample standard deviation, and \(\(n\)\) is the sample size. Plugging in the values, we get:

\(\[t = \frac{104.2 - 100}{\frac{9}{\sqrt{15}}} = 2.604\]\)

(b) To determine the critical value(s) at the significance level \(\(\alpha = 0.1\)\), we need to find the value(s) that cut off the tails of the t-distribution. Since this is a two-tailed test, we divide the significance level by 2. Looking up the critical value(s) in the t-distribution table or using a statistical calculator, we find that the critical value(s) is approximately \(\(\pm 1.761\)\).

(c) The critical region is the area under the t-distribution curve that corresponds to the critical value(s) obtained in part (b). Since this is a two-tailed test, the critical region consists of the two tails of the distribution.

(d) To determine whether the researcher will reject the null hypothesis, we compare the test statistic from part (a) with the critical value(s) from part (b). If the test statistic falls in the critical region, we reject the null hypothesis; otherwise, we fail to reject the null hypothesis. In this case, the test statistic of 2.604 does not fall in the critical region \((\(\pm 1.761\))\), so the researcher will fail to reject the null hypothesis.

Answer:

y = -0.3x + 105

Step-by-step explanation:

slope-intercept form: y = mx + b

so look at the first two points given (25, 97.5) and (35, 94.5),

you can find its slope m by using m = (change in y) / (change in x)

                                                           = (94.5-97.5) / (35-25)

                                                           = (-3) / (10) = -0.3

now you know y = -0.3x + b, sub the first point (25, 97.5) into the equation of this line, you get 97.5 = (-0.3)*(25) + b => b = 97.5 - (-7.5) = 105

so final answer y = -0.3x + 105

Done :)

The required  linear equation is  y = -0.3x + 105.

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

The Table for different values of x and y is given in the problem.

In order to find the linear equation, at first the slope has to be found as follows,

Select two values of x and y for the given table as (25, 97.5) and (35, 94.5).

For these two points the slope can be found using the expression,

slope = (y₂ - y₁) / (x₂ - x₁)

          = (97.5 - 94.5) /(25 - 35)

          = -3/10

Now, the equation for the slope -3/10 and point (25, 97.5) is,

y - 97.5 = -3/10(x - 25)

=> 10y - 975 = -3x + 75

=> y = -0.3x + 105

Hence, the equation for given table is y = -0.3x + 105.

For the given question,

A fair dice is rolled twice.

Six different results are available with a single roll of the dice (1,2,3,4,5,6)

Therefore, if two dice are rolled, there are a total of 36 possible results, or 6².

Sample space for the sum of even = [(1,1), (1,3), (1,5), (2,2), (2, 4),(2,6), (3, 1), (3,3),(3,5),(4,2),(4,4),(4,6), (5, 1), (5,3),(5,5),(6,2),(6,4),(6,6)]

Total sample space for sum of even = 18

For the probability that the sum of the numbers rolled is even is -

The probability of the value of p(a ∩ bc ) is 1/54

Probability is a mathematical measure of how likely an event is to occur.

Given that p(a ∪ b) = 2/3, which means the probability of either event a or event b happening is 2/3, we can find the probability of a and b happening simultaneously using the formula for conditional probability.

=> p(a ∩ b) = p(a | b) * p(b) = 1/12,

where p(a | b) is the probability of event a happening given that event b has already happened. We can use this information to find p(b) as follows:

=> p(b) = p(a ∩ b) / p(a | b) = 1/12 / p(a | b)

We also know that p(b ∩ ac) = 1/3, which means the probability of both events b and ac happening is 1/3. We can use this information to find p(b) and p(a | b).

=> p(b) = p(b ∩ ac) / p(ac | b) = 1/3 / p(ac | b)

Finally, using the formula for conditional probability, we can find p(a ∩ bc) as follows:

p(a ∩ bc) = p(a | bc) * p(bc) = p(a | b) * p(b | bc) * p(bc) = p(a | b) * p(b) * p(bc | b) * p(bc)

p(a ∩ bc) = 2/3 * 1/12 *1/3 = 1/54
