Answer:

-54

Step-by-step explanation:

When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities.

According to me , independent is the word which is associated with multiplication when computing probabilities . Because when the events are independent then we multiply the probabilities .

According to the multiplication rule of probability, the probability of occurrence of both the events A and B is equal to the product of the probability of B occurring and the conditional probability that event A occurring given that event B occurs.

The probability of the union of two events is equal to the sum of individual probabilities. The union of two set contains all the elements of previous sets. The union is denoted by ∪. The equation for the students earnings will be expressed as P(A∪B). The occurrence of event A changes the probability of B then the events are dependent. If the probability of two events happening together is zero then the events are mutually exclusive.

Therefore,

When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities.

Hypothesis: If two angles are congruent.

Conclusion: Then they have the same measure.

The hypothesis states that if two angles are congruent, which means they are identical in shape and size, then the conclusion is that they have the same measure. In other words, when two angles are congruent, their measures are equal.

Angles are typically measured in degrees or radians. When we say that two angles are congruent, it implies that the measures of those angles are the same. This can be understood through the transitive property of congruence, which states that if two angles are congruent to a third angle, then they are congruent to each other.

For example, if angle A is congruent to angle B, and angle B is congruent to angle C, then it follows that angle A is congruent to angle C. This implies that the measures of angle A and angle C are equal, as congruent angles have the same measure.

In conclusion, the hypothesis that if two angles are congruent implies that they have the same measure is valid and supported by the principles of congruence and the transitive property.

The relationship between variable F and x is 2x + 12000000/x

Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence.

Let F represent the length of fencing in feet.

Area of fencing = 6000000 ft²

Area of fencing = x * (y + y) = x * 2y

Area of fencing = 2xy

6000000=2xy

xy = 3000000

y = 3000000/x

The perimeter is:

F = x + y + y + x + y + y

F = 2x + 4y

F = 2x + 4(3000000/x)

F = 2x + 12000000/x

Therefore the relationship between variable F and x is 2x + 12000000/x

On solving the provided question, we can say that - Area enclosed by the square and the circle= 400 - 314 = 86 ft sq

Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

Side of the square =20feet

Therefore,

Radius of the inscribed circle= 20/2 = 10 feet

Area of square=20 X 20 = 400 feet sq.

Area of circle=\(\pi * r^{2} \\\pi * 10*10\\3.14*100\\314 ft sq\)

In the given statement, P(A) = 0.7 and P(A') = 0.2. However, these values do not satisfy the requirement that their sum is equal to 1. Therefore, the statement is not consistent and does not make sense.

When an experiment is performed several times under identical circumstances, the proportion (or relative frequency) of times that the event is anticipated to occur is known as the probability of the event.

The statement "P(A) = 0.7 & P(A') = 0.2" does not make sense because the probability of an event and its complement must add up to 1.

The complement of an event A, denoted as A', represents all outcomes that are not in A. In other words, A' includes all the outcomes that are not considered in event A.

Therefore, if P(A) represents the probability of event A occurring, then P(A') represents the probability of event A not occurring.

Since event A and its complement A' cover all possible outcomes, their probabilities must add up to 1. Mathematically, we have:

P(A) + P(A') = 1

In the given statement, P(A) = 0.7 and P(A') = 0.2. However, these values do not satisfy the requirement that their sum is equal to 1. Therefore, the statement is not consistent and does not make sense.

Answer: Black

Step-by-step explanation: There are 12 squares, so just think of a multiple of 12 that is close to 64.

12*5 = 60

So the same pattern can be repeated 5 times, the 60th square would be the last one, so the new pattern starts with 61, which is black.

62 and 63 would be white, so 64 is the 4th square, which is black.

If the pattern is repeated than the color of square 61 is black.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given patterns has 12 square which has 4 black shades.

Answer:

c-a=B

Step-by-step explanation:

if A+B=c then you subtract a from c and you get b

Answer:

C. c - a = b

Step-by-step explanation:

a + b = c

There are many ways to rearrange this equation. This can be done through addition and subtraction.

First, let's handle a. a is positive; therefore, we should subtract it.

a + b = c

b = c - a

Next, let's handle b. b is also positive; therefore, we should subtract it.

a + b = c

a = c - b

Finally, we will handle c. c is once again positive; therefore we should subtract it. However, it is the only variable on the right side, which would leave 0. This is not an option, so we will not look at this.

From our options, we can see that we have produced: b = c - a

This is an option, which has been written as c - a = b.

Therefore, your answer is C. c - a = b

Step-by-step explanation:

To find the area of a triangle, we can use the formula:

Area = (1/2) × base × height

In this case, we have three sides of the triangle given: 5, 3, and 4. To use these to find the area, we need to first determine which side is the base and what the corresponding height is.

We can see that the side with length 5 is opposite the biggest angle, so this is likely the hypotenuse. The other two sides, 3 and 4, must then be the other two legs of a right triangle, with one of them being the base and the other the height.

To determine which is which, we can use the Pythagorean theorem:

c^2 = a^2 + b^2

where c is the hypotenuse and a and b are the other two sides. In this case, we have:

5^2 = 3^2 + 4^2

25 = 9 + 16

So we have confirmed that 3 and 4 are indeed the legs of a right triangle, with 5 as the hypotenuse. We can use the Pythagorean theorem again to find the height:

a^2 + b^2 = c^2

b^2 = c^2 - a^2

b = sqrt(c^2 - a^2)    (taking the positive square root because b is a length)

b = sqrt(5^2 - 3^2)

b = sqrt(16)

b = 4

So the height of the triangle is 4. We can now use the formula to find the area:

Area = (1/2) × base × height

Area = (1/2) × 3 × 4

Area = 6

Therefore, the area of the triangle is 6 square units.
