The answer of the given question based on the mutually exclusive event is the probability of event R3 given event Q is 0.37.

Probability is  branch of mathematics that deals with  study of random events or phenomena. It is concerned with quantifying the likelihood of an event or a set of events occurring. Probability is often expressed as a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event.

Using Bayes' theorem, we can find the probability of event R3 given event Q as follows:

P(R3|Q) = P(Q|R3)*P(R3)/P(Q)

so, by using the law of total probability:

P(Q) = P(Q | R1) * P(R1) + P(Q | R2) * P(R2) + P(Q | R3) * P(R3)

Substituting the given values, we get:

P(Q) = (0.5 * 0.05) + (0.6 * 0.3) + (0.2 * 0.65)

= 0.0425 + 0.18 + 0.13

= 0.3525

Now, substituting the given values for P(Q | R3) and P(R3), we get:

P(R3 | Q) = (0.2 * 0.65) / 0.3525

= 0.37

Therefore, the probability of event R3 given event Q is 0.37.

Where the above probability condition exists,

a. The probability value of 0.049 indicates that the sample results could not have easily occurred by chance. Therefore, we can conclude that there is sufficient evidence to suggest that 200 mg of caffeine has an enhancing effect on long-term memory.

b. The probability value of 0.75 indicates that the difference in performance between the two groups could easily be due to chance. Therefore, we cannot conclude that there is a significant difference in performance between the 200 mg and 300 mg groups based on this probability value. However, further research may be needed to investigate this question more thoroughly.

The study found that participants who were given 200mg of caffeine performed better on a memory test 24 hours later compared to the placebo group. With a probability of 0.049, it can be concluded that the difference between the two groups was not due to chance.

Therefore, there is sufficient evidence to suggest that caffeine has an enhancing effect on long-term memory. On the other hand, the group given 300mg of caffeine did not show a significant difference compared to the 200mg group, with a probability of 0.75 that the difference was due to chance.

By solving the equation we know that the correct value of (D) x is 4.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

The four mathematical operations of addition, subtraction, multiplication, and division are also used in simple equations, either singly or in combination.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the value of the variable x is 7.

So, solve for the given equation:

|-4+5x|=16

5x - 4 = 16

Now, by looking at the equation we can tell that the value of x needs to be 4 as follows:

5x - 4 = 16

5(4) - 4 = 16

20 - 4 = 16

16 = 16

Therefore, it is not possible to divide the fields into identical rectangular flower beds of length 6m.

Area is a mathematical concept that refers to the measure of a surface enclosed by a boundary. It is typically expressed in square units such as square meters, square feet, or square centimeters. The area of a flat or 2-dimensional shape can be calculated by multiplying its length by its width, while the area of a 3-dimensional shape such as a cube or a sphere can be calculated using more complex formulas. Area is an important concept in geometry, physics, engineering, and many other fields.

Here,

Let the breadth of each flower bed be b.

For the first field with area 60m², the length of the field is 60/b, so the number of flower beds that can be made in this field is (60/b)/(6) = 10/b.

For the second field with area 84m², the length of the field is 84/b, so the number of flower beds that can be made in this field is (84/b)/(6) = 14/b

For the third field with area 108m², the length of the field is 108/b, so the number of flower beds that can be made in this field is (108/b)/(6) = 18/b.

Since all the fields are to be divided into identical rectangular flower beds, the number of flower beds in each field must be the same. So we have:

10/b = 14/b = 18/b

Multiplying both sides by b, we get:

10 = 14 = 18

This is not possible, so there is no common value of b that satisfies the given conditions.

The area of the shaded region is the sum of the area of the semicircle and the area of the rectangle, giving us an answer of 32.13m².

A semicircle is considered as a two-dimensional shape that is half of a circle. It is formed by drawing a line from the center point of a circle to one of its edges. The line becomes the diameter of the semicircle, and the two sides of the semicircle form an arc.

The shaded area in the diagram is the region which is bounded by the semicircle and the rectangle.

To find the area of this shaded region, we first need to find the area of the semicircle and the area of the rectangle. The area of the semicircle is derived from the formula A = (πr²)/2, where r is the radius of the semicircle. The radius of the semicircle can be found by dividing the length of the rectangle by 2, as the semicircle is half of the rectangle, giving us a radius of 3m.

Therefore, the area of the semicircle is 14.13 m². The area of the rectangle is the length of the rectangle multiplied by its width, which is 6m×3m = 18m².

Finally, the area of the shaded region is the sum of the area of the semicircle and the area of the rectangle, giving us an answer of 32.13m².

Yes, the set of coordinate points (5, 31), (6, 28), (7, 25), (8, 22), and (9, 19) forms a function.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To determine whether the set of coordinate points (5, 31), (6, 28), (7, 25), (8, 22), and (9, 19) forms a function, we need to check whether each x-value is paired with a unique y-value.

We can see that for each x-value in the set, there is only one corresponding y-value.

Therefore, the set of coordinate points does form a function.

We can also verify this by using the vertical line test.

If we draw a vertical line anywhere on the graph of this set of points, the line will intersect the graph at most once, indicating that each x-value is paired with a unique y-value.

Therefore, the coordinate points does form a function.

The pet store donated 5 percent of $7,900 to hospitals.

How to find the percentage of a number?

To find the percentage of a number, we can use the formula:

(percent) = (part / whole) x 100

Where "part" is the portion we want to find the percentage of, and "whole" is the total amount. The result gives us the percentage of the part relative to the whole.

Calculation of the percentage donated to hospitals -

In this problem, we are given that a pet store donated a percentage of every sale to hospitals, and we need to find out what percentage of $7,900 was donated. We are also given that the total donation amount was $395.

To solve this problem, we can use the percentage formula, with the part being the donation amount ($395) and the whole being the total sales ($7,900).

Substituting these values into the formula, we get:

(percent donated) = (395 / 7,900) x 100

Simplifying the fraction, we get:

(percent donated) = 0.05 x 100

Multiplying 0.05 by 100 gives us 5

Therefore, the pet store donated 5% of $7,900 to hospitals.
