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.

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.

Answer: 15 3/4 cups

In order to figure out how much peanut butter they have used we must multiply our amount by the number used.

4 1/2 times 3 1/2 can also be written as 4.5 and 3.5, respectively.

So our equation would be 4.5 x 3.5

4.5 x 3.5 is 15.75  

The number .75 can be written as the fraction 3/4, since 75 is 3/4th of 100.

This means the cafeteria used 15 3/4 cups of peanut butter.

I hope this helped & Good Luck <3 !!!

To calculate the amount of peanut butter used, multiply the number of jars (3 1/2) by the quantity in each jar (4 1/2 cups). This equals 15 3/4 cups of peanut butter.

To find out how many cups of peanut butter the cafeteria has used, we need to multiply the number of jars used by the number of cups in each jar. We know that there are 4 1/2 cups in one jar of peanut butter and the cafeteria has used 3 1/2 jars. So, we multiply 4 1/2 by 3 1/2 to get the total number of cups used.

This can be done by converting the mixed fractions to improper fractions: 4 1/2 becomes 9/2 and 3 1/2 becomes 7/2. Multiplying these gives 63/4, which converts back to the mixed number 15 3/4.

So, the cafeteria has used 15 3/4 cups of peanut butter.

The area of the triangle is given as follows:

9.3 units².

The area of a triangle is obtained multiplying the triangle's base by the triangle's height and dividing by 2, that is:

A = bh/2.

Considering segment (-5,3) to (-5,6) as the base, the base length is given as follows:

b = 6 - 3 = 3.

The midpoint of the base segment is given as follows:

(-5,4.5).

The height is given by the distance between the third vertex and the midpoint, hence:

h = sqrt[(-5 - 1)² + (4.5-3)²]

h = 6.2.

The value of m if the ratio of their heights is equal to 1:m is 4/3.

Ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that;

Area of A=144cm²

Area of B=256cm²

Ratio of heights= 1:m

Now,

The ratio of the areas of two similar solids is equal to the square of the ratio of their corresponding heights. So, we have:

(area of A) / (area of B) = (height of A)^2 / (height of B)^2

Substituting the given values, we get:

144 / 256 = 1^2 / m^2

9 / 16 = 1 / m^2

Multiplying both sides by m^2, we get:

9m^2 / 16 = 1

Multiplying both sides by 16/9, we get:

m^2 = 16/9

Taking the square root of both sides (and noting that m must be positive since it is a length), we get:

m = 4/3

Step-by-step explanation:

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 oven will heat up by 18 degrees in 1 minute at this rate.

What is expressions ?

Expressions can be simplified, evaluated, or manipulated using mathematical rules and operations. They are used in a variety of mathematical contexts, such as algebra, geometry, calculus, and more.

We can start by finding the rate of temperature increase per minute. Since the temperature rose 3 degrees in 1/6 of a minute, we can multiply both sides by 6 to find the rate per minute:

3 degrees ÷ (1/6 minute) = 18 degrees per minute

So the oven heats up at a rate of 18 degrees per minute. To find how much the oven will heat up in 1 minute, we simply multiply the rate by the time:

18 degrees per minute × 1 minute = 18 degrees

Therefore, the oven will heat up by 18 degrees in 1 minute at this rate.

The net price using the net price factor, complement method is $2958.75.

The complementary of the product of the market discount rates is represented by the net price factor, which is a decimal number. It is used to determine an item's final price after various trade discounts have been applied. By multiplying the complementary of the discount rates collectively and deducting the result from 1, we may determine the net price factor.

We use the complement method to calculate the net price using the net price factor.

For the given trade discount rates we have:

The complement of 35% is 65%

The complement of 30% is 70%

The complement of 5% is 95%

Multiply the values:

65% × 70% × 95% = 0.65 × 0.70 × 0.95 = 0.40825

The net price is obtained by:

1 - 0.40825 = 0.59175

Multiply the net price by the list price:

0.59175 × 5000 = $2958.75

With speed=10 m/s, the rope will hit ground after 3.36 seconds.

Speed is a measure of how fast an object is moving, usually measured in units of distance per unit time, such as meters per second (m/s) or kilometers per hour (km/h). It is a scalar quantity, meaning it only has magnitude and no direction.

Mathematically, speed is defined as the distance an object travels per unit time. The formula for calculating speed is:

Speed = Distance / Time

where Distance is the distance traveled by the object, and Time is the time taken to cover that distance.

here, we have,

Now,

To find when the rope will hit the ground, we can use the kinematic equation:

y = vi * t + (1/2) * a * t²

where:

y = 50 m (the height of the cliff)

vi = 10 m/s (the initial velocity of the rope)

a = 9.8 m/s² (the acceleration due to gravity, acting downward)

t = time it takes for the rope to hit the ground

We can solve for t by setting y=50 and solving for t:

50 = 10t + (1/2) * 9.8 * t²

50 = t(10 + 4.9t)

t = 50/14.9=3.36 s

Therefore, the rope will hit the ground after 3.36 seconds.

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.

f(x)=(3x+2) and g(x)=3x-5

Answer:

16.48%

Step-by-step explanation:

6 democrates

3 republicans

5 independents

Total number: 6+3+5=14

Probability of selecting an independent:

#of independents/ Total number

5/14= 0.3571

Probability of selecting a democrat:

# of democrats/ Total number-1

6/13= 0.4615

Probability of independent then democrat:

0.3571x0.4615=0.1648

0.1648x100= 16.48%
