Answer:

\( \boxed{\sf Mass \ (M) \ of \ the \ round \ ball = 10 \ grams} \)

Given:

Volume (V) = 10 millilitres

Density (\( \sf \rho \)) = 1 gram/millilitre

To Find:

Mass (M) of the round ball

Step-by-step explanation:

Formula:

\( \boxed{ \bold{Density \: ( \rho) = \frac{Mass \ (M)}{Volume \ (V)} }}\)

\( \sf \implies Mass \ (M) = Density \ (\rho) \times Volume \ (V)\)

Substituting value of density (\( \sf \rho \)) & volume (V) in the equation:

\( \sf \implies M = 1 \times 10 \\ \\ \sf \implies M = 10 \: grams\)

\( \therefore\)

Mass (M) of the round ball = 10 grams

The zeros of the polynomial function f(x) are 3, -[(2 -i√2) / 3] and  -[(2 + i√2) / 3]

To find the zeros of the polynomial function f(x), we need to find the values of x for which f(x) = 0.

We can start by factoring out a common factor of 3x^2 from the polynomial:

f(x) = 3x^3 - 5x^2 - 10x - 6

f(x) = 3x^2(x - 5/3) - 2(5x + 3)

Now, we can set each factor equal to zero and solve for x:

3x^2(x - 5/3) - 2(5x + 3) = 0

3x^3 - 5x^2 - 10x - 6 = 0

x = 3, -[(2 -i√2) / 3],  -[(2 + i√2) / 3]

The correct answer is D. All of the above. When the spread of scores around the arithmetic mean gets smaller, it means that the data points are closer to the mean.

This has several implications:
A. The coefficient of variation (CV) gets smaller: The coefficient of variation is the ratio of the standard deviation to the mean. When the standard deviation decreases (due to smaller spread of scores), the CV also decreases.
B. The interquartile range (IQR) gets smaller: The IQR represents the range between the first quartile and the third quartile. When the spread of scores decreases, the values at the first and third quartiles are closer together, resulting in a smaller IQR.
C. The standard deviation gets smaller: The standard deviation measures the average distance of data points from the mean. As the spread of scores decreases, the data points are closer to the mean, resulting in a smaller standard deviation.
In summary, when the spread of scores around the arithmetic mean gets smaller, the coefficient of variation, interquartile range, and standard deviation all decrease.

Finding the volume of a cylinder is similar to finding the volume of a prism because both structures have congruent and parallel bases. In both cases, the volume is obtained by multiplying the area of the base (a polygon for a prism and a circle for a cylinder) by the height of the figure.

The volume of a cylinder is determined by multiplying the area of its base, which is a circle, by its height. Similarly, the volume of a prism is found by multiplying the area of its base, which is a polygon, by its height.

In both cylinders and prisms, the bases are congruent, meaning they have the same shape and size. The bases are also parallel, as they lie in parallel planes. This similarity allows for the application of the same formula to calculate their volumes.

By multiplying the area of the base by the height, we are essentially stacking identical cross-sectional areas (the base) along the height of the figure to form a solid shape. This process accounts for the three-dimensional space occupied by the figure and provides an accurate measure of its volume.

Therefore, despite their different cross-sectional shapes, cylinders and prisms share the same approach to finding volume, emphasizing the congruence and parallelism of their bases and the multiplication of base area by height.

When analyzing categorical data, it is often useful to examine the relationship between two variables. Crosstabs, or contingency tables, are commonly used to display the counts of observations in each combination of the two variables. However, these raw counts can be difficult to interpret, especially if the totals for each variable are different.
By transforming the counts into percentages of row or column totals, we can better understand the patterns and relationships in the data. Percentages allow us to compare the proportions of one variable within each category of the other variable, regardless of the total number of observations. This can help us identify any trends or patterns in the data that may not be immediately apparent from the raw counts.

For example, suppose we have a crosstab of gender and favorite color. The raw counts may show that more females than males prefer blue, but it's difficult to know if this difference is meaningful without knowing the total number of males and females in the sample. By transforming the counts to percentages of row totals, we can see that 40% of females prefer blue, while only 30% of males do. This suggests that there may be a relationship between gender and favorite color.

Overall, transforming raw counts into percentages of row or column totals can help us better understand the relationship between two categorical variables, especially when the totals are different.

The value of the intercept of the regression line, b, rounded to one decimal place, is 8.1.

To find the intercept of the regression line, we need to perform linear regression analysis on the given data. The regression line is an equation of the form y = mx + b, where m is the slope and b is the intercept.

We can use a statistical software or a calculator to perform linear regression analysis. Here, we will use Microsoft Excel to find the intercept of the regression line.

First, we will create a scatter plot of the data. Then, we will add a trendline and display the equation of the trendline on the chart.

After performing linear regression analysis on the given data, we get the equation of the regression line as:

y = 1.9444x + 8.1389

Here, the intercept of the regression line is the value of b, which is 8.1389. Rounding it to one decimal place, we get the intercept as 8.1.

The intercept of the regression line is the point where the regression line intersects with the y-axis. In this context, it represents the predicted value of y when x is equal to zero. In other words, it is the starting point of the regression line.

In this example, the intercept of the regression line indicates that an employee with zero years of experience would be expected to have a salary of $8.1 thousand.

The given set {x1, x2, x3, x4, x5} is spanned in R3. To form a basis for R3, it is necessary to remove linearly dependent vectors, which can be done by applying row operations to the augmented matrix of the vectors. The resulting set of linearly independent vectors will be a basis for R3.

To pare down the set {x1, x2, x3, x4, x5} to form a basis for r3, we need to determine which vectors in the set are linearly independent and which are linearly dependent. One way to do this is to form a matrix using the vectors as columns and row reduce it to echelon form. Then, we can easily see which columns correspond to pivot variables and which correspond to free variables.

Assuming that the vectors x1, x2, x3, x4, and x5 are column vectors, we can form the matrix A as follows

A =\(\left[\begin{array}{c}x1\\x2&x3&x4\\x5\end{array}\right]\)

We then row reduce A to echelon form using elementary row operations

R1 = x1

R2 = x2 - k1 x1

R3 = x3 - k2 x1

R4 = x4 - k3 x1

R5 = x5 - k4 x1 - k5 (x2 - k1 x1) - k6 (x3 - k2 x1) - k7 (x4 - k3 x1)

where k1, k2, k3, k4, k5, k6, and k7 are constants chosen to eliminate the appropriate entries in each row.

After row reducing A, we get

\(\left[\begin{array}{ccccc}1&0&0&a1&a2\\0&1&0&b1&b2\\0&0&1&c1&c2\\0&0&0&0&0\\0&0&0&0&0\end{array}\right]\)

where a1, a2, b1, b2, c1, and c2 are constants.

Since there are three pivot columns (corresponding to x1, x2, and x3), the set {x1, x2, x3} is linearly independent and spans R3. Therefore, it forms a basis for R3. The vectors x4 and x5 are linearly dependent on x1, x2, and x3, and can be expressed as linear combinations of those vectors.

\(c_0 = 9, c_1 = 2(9^2), c_2 = 3(9^3), c_3 = 4(9^4)\)and \(c_4 = 5(9^5)\). The radius of convergence R is infinity.

To find the coefficients of the power series representation of the function f(x) = 5/(1 - 9x)², we can expand the function using the geometric series formula. The formula states that for |x| < 1, we have:

1/(1 - 9x) = 1 + 9x + (9x)² + (9x)³ + ...

Now, let's differentiate both sides of the equation with respect to x:

d/dx [1/(1 - 9x)] = d/dx [1 + 9x + (9x)² + (9x)³ + ...]

To differentiate the left side, we can use the power rule:

d/dx [1/(1 - 9x)] = (1 - 9x)⁻²

To differentiate the right side, we differentiate each term individually. Since the derivative of x^n with respect to x is nxⁿ⁻¹, the terms with powers of x become:

d/dx [1 + 9x + (9x)² + (9x)³ + ...] = 0 + 9 + 2(9²)x + 3(9³)x² + ...

Equating the derivatives, we have:

(1 - 9x)⁻² = 9 + 2(9²)x + 3(9³)x² + ...

To obtain the coefficients of the power series representation, we compare the terms on both sides of the equation. Since the expression on the right side is already in the desired form, we can read off the coefficients as follows:

\(c_0 = 9\\c_1 = 2(9^2)\\c_2 = 3(9^3)\\c_3 = 4(9^4)\\c_4 = 5(9^5)\)

Now, let's find the radius of convergence R of the series. The radius of convergence can be determined using the ratio test. The ratio test states that if the limit of |\(c_{n+1} / c_n\)| as n approaches infinity is L, then the series converges if L < 1 and diverges if L > 1.

Applying the ratio test to our series, we have:

|\(c_{n+1} / c_n\)| = |[(n+1)(9ⁿ⁺¹)] / [n(9ⁿ)]| = 9((n+1)/n)

Taking the limit as n approaches infinity, we get:

lim(n->∞) |\(c_{n+1}/ c_n\)| = lim(n->∞) 9((n+1)/n) = 9

Since the limit is 9, which is less than 1, the series converges for all values of x within a radius of convergence R. Therefore, the radius of convergence R is infinity (R = ∞).

Therefore,\(c_0 = 9, c_1 = 2(9^2), c_2 = 3(9^3), c_3 = 4(9^4)\)and \(c_4 = 5(9^5)\). The radius of convergence R is infinity.

Step-by-step explanation:

The total cost of Cole's breakfast, including an 18% tip, was $94.40. If the bill came to $80, and Cole left an 18% tip, then the tip amount would be calculated by multiplying the bill amount by 0.18 (or 18%).

Tip = $80 x 0.18 = $14.40

To calculate the total cost of Cole's breakfast, we need to add the tip amount to the bill amount:

Total cost = $80 + $14.40 = $94.40

Therefore, the total cost of Cole's breakfast, including an 18% tip, was $94.40. It is customary to leave a tip in the United States, and the amount typically ranges from 15-20% of the bill. The tip is a way to show appreciation for good service and is an important part of the restaurant industry's compensation model.

The given linear regression model means that 90% of the variation in long jump distances is explained by the regression line. (Option C)

Linear regression refers to a basic and commonly used form of predictive analysis. It is used to determine the relationship between two quantitative variables. It is used to determine the strength of the relationship between two variables and the value of the dependent variable at a certain value of the independent variable. Regression models describe the relationship between variables by fitting a line to the observed data. Linear regression models use a straight line, while logistic and nonlinear regression models use a curved line. The regression model illustrates how a dependent variable changes as the independent variable(s) change.  The given linear regression model r2= 0.90, where r2 gives the proportion of the variation in the long jump explained by the change in years, the model means that 90% of the variation in long jump distances is explained by the regression line.

The approximate probability that the total score is at least 375 when a fair six-sided die is rolled 100 times is (d) 0.4420.

When a fair six-sided die is rolled, the random variable X represents the outcome. The mean (μX) of X is 3.5, and the standard deviation (σX) is 1.71.

To find the probability that the total score is at least 375 when the die is rolled 100 times, we can use the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approximates a normal distribution.

In this case, the sum of the outcomes of 100 rolls of the die follows a normal distribution with a mean of μX multiplied by the number of rolls (100) and a standard deviation of σX multiplied by the square root of the number of rolls (10). Therefore, the approximate probability can be calculated by finding the probability that the sum is greater than or equal to 375.

Using a normal distribution table or a calculator, we can find that the approximate probability is 0.4420, which corresponds to answer (d). This means that there is a 44.20% chance that the total score will be at least 375 when the die is rolled 100 times.

The coordinates of the vertices after rotation depend on the point around which rotation is done.

Rotation of a shape around the origin (0,0) means that each point in the shape has to be moved around the origin by a certain angle. This is done by using the equation x'=xcosθ-ysinθ and y'=xsinθ+ycosθ, where x and y are the coordinates of the point before rotation and x' and y' are the coordinates of the point after rotation. In this case, the angle of rotation is 90 degrees. When we rotate triangle LMN by 90 degrees around the origin, the coordinates of the vertices become L'(2,2), M'(-4,6) and N'(4,-5).When we rotate the triangle around any of the points of L, M, or N, the coordinates of the vertices will change accordingly. For example, if we rotate the triangle around point L, the coordinates of the vertices become L'(2,-2), M'(-2,4) and N'(-6,0). Similarly, if we rotate the triangle around point M, the coordinates of the vertices become L'(2,-2), M'(6,-4) and N'(0,6). Lastly, if we rotate the triangle around point N, the coordinates of the vertices become L'(2,-2), M'(4,5) and N'(5,4).
