the longer diagonal of a field in the shape of a quadrilateral is 120 m and the length of the perpendiculars from the opposite vertex upon a longer diagonal is 20 m and 30 m find the area of the field Step by Step Explaination class 8 lesson no 11 mensuration
The area of the field is 900√10 m².
What is the Pythagorean theorem?Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We can apply this theorem only in a right triangle.
Example:
The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.
Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm
We have,
Quadrilateral ABCD.
The longer diagonal connects vertices A and C, and let E and F be the feet of the perpendiculars from vertices B and D to the longer diagonal AC.
From the figure,
BE = 20 m
DF = 30 m
AE = EC = 120/2 = 60 m
Now,
The area of the quadrilateral.
The area of a trapezoid.
= (sum of parallel sides) x (height) / 2
Using the Pythagorean theorem,
AB² = AE² + BE²
60² + 20² = 4000
AB = √(4000)
AB = 20 √10
And,
CD² = CE² + DF²
CD² = 60² + 30²
CD² = 4500
CD = √(4500)
CD = 15 √20
Now,
Area = AB + CD x 1/2 x AC
= 20√10 + 15√20 x 1/2 x 120
= 900√10
Therefore,
The area of the field is 900√10 m².

What are the Nash equilibria in this game?
Both (P1=Shot, P2=Shot) and (P1=No shot, P2=No shot)
Only (P1=Shot, P2=No shot)
Both (P1=Shot, P2=No shot) and (P1=No shot, P2=shot)
the Nash equilibrium is not necessarily the best or most desirable outcome for the players involved. It simply represents a stable state where no player has an incentive to unilaterally deviate from their chosen strategy.
To determine the Nash equilibria in a game, we need to analyze the strategies of each player and identify the combinations of strategies where no player has an incentive to unilaterally deviate.
Given the options:
1. (P1=Shot, P2=Shot)
2. (P1=No shot, P2=No shot)
3. (P1=Shot, P2=No shot)
4. (P1=No shot, P2=Shot)
Let's analyze each combination:
1. (P1=Shot, P2=Shot):
If both players choose to shoot, they both face the risk of being shot and getting injured. Neither player has an incentive to deviate from this strategy, as changing to "No shot" would expose them to the risk of being shot without being able to retaliate. Therefore, (P1=Shot, P2=Shot) is a Nash equilibrium.
2. (P1=No shot, P2=No shot):
If both players choose not to shoot, they avoid the risk of being injured. Again, neither player has an incentive to unilaterally deviate from this strategy, as changing to "Shot" would expose them to the risk of being injured without gaining any advantage. Therefore, (P1=No shot, P2=No shot) is a Nash equilibrium.
3. (P1=Shot, P2=No shot):
If Player 1 chooses to shoot while Player 2 chooses not to shoot, Player 1 has an advantage and can potentially eliminate Player 2 without being injured. In this scenario, Player 2 may have an incentive to deviate from "No shot" and switch to "Shot" to protect themselves. Therefore, (P1=Shot, P2=No shot) is not a Nash equilibrium.
4. (P1=No shot, P2=Shot):
Similarly, if Player 1 chooses not to shoot while Player 2 chooses to shoot, Player 2 has an advantage and can potentially eliminate Player 1 without being injured. In this scenario, Player 1 may have an incentive to deviate from "No shot" and switch to "Shot" to protect themselves. Therefore, (P1=No shot, P2=Shot) is not a Nash equilibrium.
Based on the analysis, the Nash equilibria in this game are:
- (P1=Shot, P2=Shot)
- (P1=No shot, P2=No shot)

The given mathematical expression is evaluated for the input values (2, 4). The result of the expression is calculated using various operations such as addition, multiplication, square root, natural logarithm, minimum, maximum, and function composition.
The expression f(x1, x2) involves several mathematical operations. Let's evaluate each part of the expression step by step:
1. The first term is 421 + 222, which equals 643.
2. The second term is 3x² + 213. Plugging in x1 = 2 and x2 = 4, we get 3(2)² + 213 = 3(4) + 213 = 12 + 213 = 225.
3. The third term is 5x11². Substituting x1 = 2 and x2 = 4, we have 5(2)(11)² = 5(2)(121) = 1210.
4. The fourth term is (√₁+√₂)². Replacing x1 = 2 and x2 = 4, we obtain (√2 + √4)² = (1 + 2)² = 3² = 9.
5. The fifth term is 10ln(₁). Plugging in x1 = 2, we have 10ln(2) = 10 * 0.69314718 ≈ 6.9314718.
6. The sixth term is (x₁+x₂)(x² + x3). Substituting x1 = 2 and x2 = 4, we get (2 + 4)(2² + 4³) = 6(4 + 64) = 6(68) = 408.
7. The seventh term is min(3r1, 10√2). As we don't have the value of r1, we cannot determine the minimum between 3r1 and 10√2.
8. The eighth term is max{5x1,2r2}. Since we don't know the value of r2, we cannot find the maximum between 5x1 and 2r2.
9. Finally, we have MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2), which are not defined or given.
Considering the given expression, the evaluated terms for the input values (2, 4) are as follows:
- 421 + 222 = 643
- 3x² + 213 = 225
- 5x11² = 1210
- (√₁+√₂)² = 9
- 10ln(₁) ≈ 6.9314718
- (x₁+x₂)(x² + x3) = 408
The terms involving min() and max() cannot be calculated without knowing the values of r1 and r2, respectively. Additionally, MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2) are not defined.

Work out the value of 5 to the power of a if it equal 1/125
Answer:
a = -3
Step-by-step explanation:
Step 1: Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:
5^a = 1/125
Step 2: Take the log of both sides
log(5^a) = log(1/125)
Step 3: According to the power rule of logs, we can bring a down and multiply it by log(5):
a * log(5) = log (1/125)
Step 4: Divide both sides by log(5) to solve for a:
(a * log(5) = log(1/125)) / log(5)
a = -3
Optional 5: We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:
5^-3 = 1/125
1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator
1/125 = 1/125
The accompanying table describes results from groups of 10 births from 10 different sets of parents. The random variable x represents the number of girls among 10 children. Use the range rule of thumb to determine whether 1 girl in 10 births is a significantly low number of girls.
Since the range of observed values is 1, which is less than two standard deviations away from 10, the observed value is not significantly different from the expected value and thus the number of girls in 10 births is not significantly low.
What is standard deviation?Standard deviation is a measure of how spread out numbers are in a data set. It is calculated by taking the square root of the variance. Variance is the average of the squared differences from the mean. Standard deviation provides an indication of how much variation there is in the data set, and is often used in statistical analysis.
The range rule of thumb is a statistical method used to determine whether a given phenomenon is significantly different from an expected value. It states that if the range of observed values is greater than two standard deviations of the expected value, then the observed values are significantly different from the expected value.
In this particular case, the expected value is 10 girls in 10 births, and the observed value is 1 girl in 10 births. Since the range of observed values is 1, which is less than two standard deviations away from 10, the observed value is not significantly different from the expected value and thus the number of girls in 10 births is not significantly low.
The range rule of thumb is one way to determine whether observed values are significantly different from expected values, but there are other methods available as well.

quadrant: ______
ordered pair: ______
origin: ______
In a Cartesian coordinate system, there are four quadrants that are used to help identify the location of points. The four quadrants are numbered I, II, III, and IV, and are named based on their location in relation to the origin.
The first quadrant, also known as Quadrant I, is the top right quadrant. It is located above the x-axis and to the right of the y-axis. Points in this quadrant have positive x and y values.
The second quadrant, also known as Quadrant II, is the top left quadrant. It is located above the x-axis and to the left of the y-axis. Points in this quadrant have negative x values and positive y values.
The third quadrant, also known as Quadrant III, is the bottom left quadrant. It is located below the x-axis and to the left of the y-axis. Points in this quadrant have negative x and y values.
The fourth quadrant, also known as Quadrant IV, is the bottom right quadrant. It is located below the x-axis and to the right of the y-axis. Points in this quadrant have positive x values and negative y values.
An ordered pair is a pair of numbers that are used to identify a point on a coordinate plane. For example, (3,4) is an ordered pair that represents the point 3 units to the right of the y-axis and 4 units above the x-axis.
The origin, also known as the point (0,0), is the point where the x-axis and y-axis intersect. It is the starting point from which all other points on the plane are measured.
In summary, In a Cartesian coordinate system, there are four quadrants that are used to help identify the location of points: Quadrant I is the top right quadrant, Quadrant II is the top left quadrant, Quadrant III is the bottom left quadrant, and Quadrant IV is the bottom right quadrant.
An ordered pair is a pair of numbers that are used to identify a point on a coordinate plane. The origin, also known as the point (0,0), is the point where the x-axis and y-axis intersect. It is the starting point from which all other points on the plane are measured.

You are the director of the customer service center in Company Alpha. You find that the mean time between calls to the center is 6 minutes with standard deviation of 4 minutes. The effective response time is 11 minutes with a standard deviation of 20 minutes. (a) Identify the following parameters: ta
tθ
∂a
∂θ
ra:
rθ:
The identified parameters are:
ta = 6 minutes
tθ = 11 minutes
∂a = 4 minutes
∂θ = 20 minutes
ra = 1/6 minutes^(-1)
rθ = 1/11 minutes^(-1)
ta: Mean time between calls to the center
tθ: Effective response time
∂a: Standard deviation of the time between calls to the center
∂θ: Standard deviation of the effective response time
ra: Rate of calls to the center (inverse of ta, i.e., ra = 1/ta)
rθ: Rate of effective response (inverse of tθ, i.e., rθ = 1/tθ)
Given information:
Mean time between calls to the center (ta) = 6 minutes
Standard deviation of time between calls (∂a) = 4 minutes
Effective response time (tθ) = 11 minutes
Standard deviation of effective response time (∂θ) = 20 minutes
Using this information, we can determine the values of the parameters:
ta = 6 minutes
tθ = 11 minutes
∂a = 4 minutes
∂θ = 20 minutes
ra = 1/ta = 1/6 minutes^(-1)
rθ = 1/tθ = 1/11 minutes^(-1)
So, the identified parameters are:
ta = 6 minutes
tθ = 11 minutes
∂a = 4 minutes
∂θ = 20 minutes

Given that the probability of a company having a section in the newspaper is 0.43, and the probability of a company having a website given that the company has a section in the newspaper is 0.84, what is the probability of a company having a website and a section in the newspaper
To find the probability of a company having both a website and a section in the newspaper, we can use the formula for conditional probability.
Let's denote the events as follows:
A: A company has a section in the newspaper
B: A company has a website
We are given the following probabilities:
P(A) = 0.43 (Probability of a company having a section in the newspaper)
P(B|A) = 0.84 (Probability of a company having a website given that it has a section in the newspaper)
The probability of both events A and B occurring can be calculated as:
P(A and B) = P(A) * P(B|A)
Substituting in the values we have:
P(A and B) = 0.43 * 0.84
P(A and B) = 0.3612
Therefore, the probability of a company having both a website and a section in the newspaper is 0.3612 or 36.12%.

Solve the system by substitution . 5x- y =21 x=2y -3
Answer:
(5,4)
Step-by-step explanation:
To solve a system of equations by substitution, you need to solve one of the equations for one variable (either x or y). In this case, we can solve the second equation for x: x=2y-3. Then substitute this expression into the first equation and solve for y: 5(2y-3)-y=21. Solving for y gives us y=4. Substitute this value back into the second equation and solve for x: x=2(4)-3=5. Therefore, the solution is (5,4).

In order for the function to be linear, what must a be and why?
a = 22 because the rate of change is 1.
a = 20 because the rate of change is 3.
a = 22 because the rate of change is –1.
a = 20 because the rate of change is –3.
For the function to be a linear, D. a = 20 because the rate of change is –3.
What is the Rate of Change of a Function?The rate of change = change in y / change in x.
Therefore, for the function to be linear, the rate of change must be the same across the table of values.
Using, (4, 26) and (5, 23):
Rate of change = (26 - 23)/(4 - 5)
Rate of change = (3)/(1) = -3
Using (5, 23) and (6, a), we have:
(23 - a)/(5 - 6) = -3
(23 - a)/(-1) = -3
23 - a = (-3)(-1)
23 - a = 3
-a = 3 - 23
-a = -20

Marc saved 30% of his monthly salary each month. His monthly salary in December was $ 3650. In January, his salary increased by 12%. How much more did he save in January than in December?plz help me.
Marc saved $2,533 in January than in December.
Step by Step calculation.
Given the details below :
Salary In December =$3,650
In January, Increased by 12%
Marc saves 30% of $3,650 in December
New salary can then be calculated as :
= Initial salary * % increase / 100 + Initial salary
= 3,650 * 12 / 100 + 3,650
= 3,650 * 0.12 + 3,650
= 4,088
The difference will now be
= 4,088 - 3650
= $438
Since Marc saves in December 30% of $3,650
= 30% of $3,650
= $1,095
Saves in January
= 1,095 + 438

A probability-dependent event is an event whose occurrence affects the probabilities of others. Suppose you have 3 red balls and 6 green balls in your pocket. Two balls are drawn one after the other from the bag. A dependent event is an event that depends on what happened before. These events are affected by previously occurring results.In other words, two or more intedependent events are called dependent events. A random change in one event can deviate from another.If two events A and B depend on each other, then the probability of A and B occurring is

Range of the third side be, 0 ft < x < 76 ft
b) 16 ft and 17 ft
given first side of the triangle be, 16 ft
and second side of the triangle be, 17 ft
as we know that the third side should be less than the sum of the remaining two sides of any triangle.
So, let the third side be x
x < 16 + 17
x < 33
Therefore, the third side should be less than 33 ft and obviously greater than 0 ft.
Range of the third side be, 0 ft < x < 33 ft
Hence, the range of possible lengths for the third side be
0 ft < x < 76 ft
0 ft < x < 33 ft

I have a secret number (x). Seven more than quadruple my number equals -5. What is
my number?
Answer:
Your number is 0.5, 2/4, or 1/2
Step-by-step explanation:
You need to set up your equation and then solve for x. We know that quadruple your number (x) plus 7 equals -5. Quadruple your number is the same as multiplying by 4. So it would be 4x + 7 = -5. We add seven to both sides and that would leave us with 4x = 2. Then we divide both sides by 4 to get x on it's own. x = 2/4 or 1/2
