Hz (Hertz) is a unit of frequency, which measures the number of events or occurrences of a certain phenomenon per second. In this case, the tape timer creates 28 dots per second, which means that the frequency of dot creation is 28 Hz.
To find the time interval between 3 successive dots, we need to calculate the time it takes for the tape timer to create 3 dots. This can be done by dividing the total time by the number of dots created.
Since the tape timer creates 28 dots per second, the time interval between 3 dots can be calculated as follows:
Time interval = 1 second / 28 dots = 1/28 seconds
So, the time interval between 3 successive dots created by the tape timer is 1/28 seconds, which is the amount of time that elapses between the creation of each dot.

The event that "a or b but not both" P{(A∩B) ∪ (A ∩B)}
= P(A∩B) + P(A∩B) - P(A∩B∩A ∩B)
In this question, we will use the addition rule of the probability to calculate the required probability. The probability is a positive quantity from zero to one inclusively. The negative probability of an event does not exist
This is for independent events
P(A U B): This is A or B or both:
P(A n B): This is A and B.
P(A U B) = P(A) + P(B) - P(A n B)
P( A n B) = P(A) x P(B)
Hence:
A or B but not both:
P(A U B) = P(A) + P(B) - P(A n B) - P(A n B) = P(A) + P(B) - 2 x P(A n B)
can also be written in terms of the conditional probability P(A|B)
So we can write

The measure of angles for questions 19) and 20) are x = 32° and x = 115° respectively using the triangle sum and exterior angle theorem.
How to evaluate for the angles x for the trianglesquestion 19 has 2 isosceles triangles and the measure of x can be derived by equating one of the base angles of the smaller triangle to the sum of its 2 opposite angles as follows;
let y be one of the base angles of the smaller triangle so that;
2y = 180 - 56 {sum of interior angles of a triangle}
2y = 124
y = 62
hence;
62 = x + x {exterior angle of a triangle equals the sum of its two opposite angles}
2x = 62
x = 31°
For question 20, we first find the two opposite angles of x as follows;
180 -(62 + 50) = 68
180 - (53 + 80) = 47
x = 68 + 47
x = 115°
Therefore, the measure of angles for questions 19) and 20) are x = 32° and x = 115° respectively using the triangle sum and exterior angle theorem.

-2 1/3x = -1 3/4
I need it rn
Answer:2
Step-by-step explanation: To solve the equation -2 1/3x = -1 3/4, we need to isolate the variable x on one side and simplify the equation.
First, we need to convert both sides to have the same denominator. We can choose the least common multiple of 3 and 4, which is 12.
-2 1/3x = -1 3/4
-2 1/3 * 4/4 * x = -1 3/4 * 3/3
-8/3 x = -5 1/3
Next, we isolate x by dividing both sides by -8/3:
(-8/3) x / (-8/3) = -5 1/3 / (-8/3)
x = (5 1/3) / (8/3)
x = (5 1/3) * (3/8)
Finally, we simplify the fraction to get the final solution:
x = (5 1/3) * (3/8)
x = (5 * 3 + 1 * 3) / 8
x = 16 / 8
x = 2
Therefore, the solution to the equation -2 1/3x = -1 3/4 is x = 2.

The probability of winning chess tournament is 0.375.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Let A₁ be the event of playing an opponent of type i.
A₁ = playing the half of the opponent pool where the probability of winning
P (winning∣A₁) = 0.3
A₂ = playing the half of the opponent pool type 2, where the probability of winning P(winning∣A₂) = 0.4
A₃ = playing the half of the opponent pool type 3, where the probability of winning P(winning∣A₃) =0.5
By total probability theorem, we get,
P(winning)=P(A₁) P(winning∣A₁) +P(A₂) P(winning∣A₂) +P(A₃) P(winning∣A₃)
P(winning)=50%×0.3+25%×0.4+25%×0.5

The probability of winning the game depends on the type of opponent. If the opponent is of type 1, the probability of winning is 0.3; type 2, 0.4; and type 3, 0.5.
The probability of winning the game depends on the type of opponent. There are three types of opponents: type 1, type 2, and type 3. Against type 1 opponents, the probability of winning is 0.3. Against type 2 opponents, the probability of winning is 0.4. Against type 3 opponents, the probability of winning is 0.5. As the opponent is chosen randomly, the probability of winning is the average of all three probabilities. This means that the probability of winning the game is 0.4. To calculate this, we first add the probabilities of winning against each type of opponent: 0.3 + 0.4 + 0.5 = 1.2. We then divide this result by the number of opponent types (3): 1.2/3 = 0.4.

Find the area and the perimeter of a rectangle with the ide length of 4 1/5 in and 4 2/7 in
The Perimeter is 16.97 inch, and the Area is 18 square inch units.
Given, Length, l = 4 1/5 inch = 21/5 inch
Breadth, b = 4 2/7 inch = 30/7 inch
The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter. The rectangle's perimeter can be expressed as the product of its length and width times two. As a linear measurement, the perimeter can be expressed in metres, centimetres, inches, feet, etc.
Perimeter of the rectangle = 2 (l + b) = 2 (21/5 + 30/7)

The Perimeter is 16.97 inches, and the Area is 18 square inch units.
Given, Length, l = 4 1/5 inch = 21/5 inch
Breadth, b = 4 2/7 inch = 30/7 inch
The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter. The rectangle's perimeter can be expressed as the product of its length and width times two. As a linear measurement, the perimeter can be expressed in meters, centimeters, inches, feet, etc.
Perimeter of the rectangle = 2 (l + b) = 2 (21/5 + 30/7)
= (147 + 150)(2/35)
= 297 x 2/35 = 16.97 inch

The equation for the discounted price should be:
A' = $25*(1 - 20%/100%) = $20
How to find the discounted price?If we have an initial value A, and we decrease it by X (a percentage) then:
The discounted amount is:
D = A*(X/100%)
The new value is:
A' = A*(1 - X/100%)
So, if the initial value is $25 and there is a discount of the 20%, the new value of the item will be:
A' = $25*(1 - 20%/100%)
A' = $25*(1 -0.2)
A' = $25*0.8 = $20
That is the correctly discounted price.
