The probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778.

To calculate the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice, we need to find the number of ways the dice can be rolled to get a sum less than or equal to 6 and divide it by the total number of possible outcomes.

There are 6 x 6 = 36 possible outcomes when rolling a pair of dice, since there are 6 possible outcomes for each die. To get a sum less than or equal to 6, the only possible outcomes are:

1+1 = 2

1+2 = 3

1+3 = 4

1+4 = 5

2+1 = 3

2+2 = 4

2+3 = 5

3+1 = 4

3+2 = 5

4+1 = 5

There are 10 possible outcomes that result in a sum less than or equal to 6. Therefore, the probability of rolling a sum less than or equal to 6 is:

P(sum less than or equal to 6) = number of favorable outcomes / total number of possible outcomes

P(sum less than or equal to 6) = 10 / 36

Simplifying this fraction, we get:

P(sum less than or equal to 6) = 5 / 18

Therefore, the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778 when rounded to four decimal places.

The probability of exactly 5 patients having kidney-related problems is approximately 0.253 or 25.3%.

The probability of a given number of patients having kidney-related problems can be found using the binomial distribution. The binomial distribution models the number of successful outcomes in a fixed number of independent trials, where each trial has the same probability of success.

In this case, each hospital admission is a trial, and the probability of success (having a kidney-related problem) is 0.3 (30%). The number of trials is 10, and we want to find the probability of exactly 5 patients having kidney-related problems.

We can use the formula for the probability mass function of the binomial distribution to find this:

[tex]P(X = k) = (n choose k) * p^k * (1-p)^(n-k)[/tex]

where:

n = 10 (number of trials)

k = 5 (number of successful outcomes)

p = 0.3 (probability of success)

Using the formula, we have:

[tex]P(X = 5) = (10 choose 5) * 0.3^5 * (1-0.3)^(10-5)= 252 * 0.3^5 * 0.7^5[/tex]

= approximately 0.253

So, the probability of exactly 5 patients having kidney-related problems is approximately 0.253 or 25.3%.

The vertex of the parabola is (2, 16). This means that the average of couches sold in Germany was the greatest in the year 2013, which is 2 years after 2011.

The equation y = -0.25(x - 2)² + 16 models the average of couches sold in Germany, where x is the number of years since 2011 and y is the number of couches sold. We can find the year when the average of couches sold in Germany was the greatest by finding the maximum value of the equation.

To find the maximum value, we can first rewrite the equation in vertex form: y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

y = -0.25(x - 2)² + 16

y = -0.25(x² - 4x + 4) + 16

y = -0.25x² + x + 15

To find the vertex of the parabola, we can use the formula h = -b/2a and k = f(h), where f(h) is the value of y at the vertex.

h = -b/2a = -1/(2*(-0.25)) = 2

k = f(h) = -0.25(2)² + 2 + 15 = 16

Therefore, the vertex of the parabola is (2, 16). This means that the average of couches sold in Germany was the greatest in the year 2013, which is 2 years after 2011.

The required equation represents the inverse function b(a), which takes the trapezoid's area is B(a) = a/6 - 9.

A trapezoid is a quadrilateral having two parallel bases and one set of other sides called as legs.

We have been given that the trapezoid's base is nine and its height is twelve.

As an outcome, 'b' is the base's parallel side.

The function that represents the trapezoid's area is given by:

A(b) = [12(b + 9)]/2

Let's consider A(b) = a

Then, a =  [12(b + 9)]/2

Now solving for b, we get

2a = 12(b + 9)

a = 6(b + 9)/2

a = 6b + 54

6b = a - 54

b = (a - 54)/6

b = a/6 - 9

Assuming that the length of the side parallel to the base 'b' = B(a), the equation will be:

B(a) = a/6 - 9

Thus, the correct answer would be option A. B(a) = a/6 - 9.

The scatter diagram for the data with college GPA as the independent variable is illustrated as follows.

In this case, we have a dataset that includes the GPA and salary of graduates ten years after graduation. We can use GPA as the independent variable (or x-axis) and salary as the dependent variable (or y-axis). We can then plot each data point on the graph, where the x-coordinate represents the GPA and the y-coordinate represents the salary.

To create the scatter plot, we first need to organize the data into pairs of GPA and salary values. For example, the first pair is (2.22, 72,000), where 2.22 is the GPA and 72,000 is the salary. We can then plot this point on the graph by locating 2.22 on the x-axis and 72,000 on the y-axis.

We repeat this process for each data point, and then connect the points with a line or a curve. The resulting scatter plot shows us the overall pattern of the relationship between GPA and salary. If there is a positive relationship between the two variables, we would expect to see the points cluster around a line that slopes upwards from left to right.

Overall, the scatter plot provides a useful visual tool for exploring the relationship between college GPA and salary. While it suggests that there is a positive relationship between the two variables, it also reminds us that there are many other factors that contribute to earnings.

50 must have been his starting number of cherries.

Seb had 50 cherries at the start. This can be determined by solving the equation 10x + 5 = 40, where x is the number of days he ate 10 cherries and gave 5 away. When you solve the equation, you get x = 5, meaning he did this 5 times. Since 10x is 50, and 5 is added to that, the total is 50. Therefore, Seb had 50 cherries at the start.

To solve the equation, you first need to subtract 5 from both sides to get 10x = 35. Then, divide both sides by 10 to get x = 3.5. Since Seb could not have eaten 3.5 days worth of cherries, it means that he did the 10 and 5 activity 4 times, giving him 40 cherries before giving away the last 5. So 40 + 5 = 45 and 10x = 50, so 50 must have been his starting number of cherries.

What is Function ?

Function can be defined in which it relates an input to output.

The point of symmetry on f-¹(x) is (4,6).

False. The point (4,6) is not on the graph of f-¹(x), so it cannot be the point of symmetry. We can verify that the function is not symmetric with respect to any vertical or horizontal line.

The domain of f-¹(x) is (-∞,4).

True. The cube root function is defined for all real numbers, so the expression inside the cube root must be nonnegative. Therefore, (z - 4) / 5 ≥ 0, which implies that z ≥ 4. This means that the domain of f-¹(x) is (-∞,4].

The graphs of f¹(x) and f(x) are reflections across the x-axis.

False. The graphs of f¹(x) and f(x) are not reflections across the x-axis. We can plot the functions to see that they have different shapes and are not symmetric with respect to the x-axis.

The range of f¹(x) is (-∞,∞).

True. The cube root function is defined for all real numbers, so f-¹(z) can take any real value. This means that the range of f¹(x) is (-∞,∞).

The total length, in inches, of the four cut boards is 130 inches.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given that, the length of each of the cut pieces of the board are 7½ inches, 10½ inches, 9 inches, and 5½ inches.

We have to find the total length of the board.

Total length of the board is found by adding each length.

Total length = 7½ + 10½ + 9 + 5½

Mixed fraction can be converted to improper fraction by cross multiplication.

7½ = (7 * 2 + 1) / 2, 10½ = (10 * 2 + 1) / 2 and 5½ = (5 * 2 + 1) / 2

Total length = 15/2 + 21/2 + 9 + 11/2

                    = (15/2 + 21/2 + 11/2) + 9

                     = 47/2 + 9

                     = 65/2

Again improper fraction can be converted to mixed fraction.

Total length of a board = 32 1/2 inches

But there are 4 boards.

Total length of the 4 boards = 4 × 65/2 = 130 inches

Hence the total length is 130 inches.

Step-by-step explanation:

[tex] \frac{y - y1}{x - x1} = m[/tex]

Therefore the gradient ( m ) is not given

from the question point =(-9,-3) and (-12,-4).

Gradient (m) =

[tex] \frac{y2 - y1}{x2 - x1} \\ = \frac{ - 4 - ( - 3)}{ - 12 - ( - 9)} \\ = \frac{ - 4 + 3}{ - 12 + 9} \\ = \frac{ - 1}{ - 3} \\ = \frac{1}{3} [/tex]

therefore m = 1/3.

The equation

[tex] = \frac{y - y1}{x - x1} = m \\ \frac{y - ( - 3)}{x - ( - 9)} = \frac{1}{3} \\ \frac{y + 3}{x + 9} = \frac{1}{3} \\ 3(y + 3) = 1(x + 9) \\ 3y + 9 = x + 9 \\ 3y = x + 9 - 9 \\ 3y = x + 0 \\ 3y - x = 0[/tex]

therefore the equation of the line = 3y-x=0
