The correct answer as per the video that demonstrates the Monty Hall Problem is option C. 20. That is how many times the men perform each strategy A and B.

Goats can be found behind two curtains and one behind each door.

Anytime a contestant selects a curtain, one of the certain to curtains informs the contestant that a goat was hiding behind all of this.

The contestant must choose one of two curtains, one of which has a car in it and the other of which has a goat on it. Therefore, there is an equal chance of. choosing either a goat or a car.

Similar to that, provided.

Probability A for strategies and tactics is 10%, or 2 out of every 20 trials.

80% of Strategy B's chance is equal to 16 accomplishments spread across 20 directions.

Thus,

16 success = 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success

Taking the common factor,

16 success = 8 (2 success)

Taking percentage on both sides,

80% = 8×10%

80% = 80%

Hence, the result value is as expected.

Jade was 416 meters above the ground when she deployed her canopy.

What is kinematics?

kinematics, specifically the equation of motion for constant velocity, to solve the problem of finding the height above the ground when a person deploys their canopy while descending.

We can use the formula:

height = rate x time

To determine how high Jade was above the ground when she deployed her canopy. Let's denote the height she was at when she deployed her canopy as "h".

From the given information, we know that Jade descended at a constant rate of 40 meters every 5 seconds, so her rate of descent is 40/5 = 8 meters per second.

We also know that it took her exactly 57 seconds to reach the ground. Therefore, the time she spent descending with her canopy deployed is 57 - 5 = 52 seconds.

Using the formula, we can write:

h = 8 x 52

Simplifying this equation gives us:

h = 416

Hence, Jade was 416 meters above the ground when she deployed her canopy.

Answer:

4√3 or 6.9282Km

Step-by-step explanation:

Let the triangle be ABC, right angled at B

Angle A = 60 degrees

Angle C = 30 degrees

BC = 6 km

To find AB,

Tan30°=AB/BC

Now we know that tan30° is 1/√3 so,

1/√3 = AB / 6

6/√3 = AB

6√3/3 =AB

2√3 = AB

Now we have the value of two sides so we can use the Pythagoras Theorem to find the hypotenuse, which is g

AB² + BC² = AC²

(2√3)² + 6² = g²

12 + 36 = g²

48 = g²

Therefore g = √48km or 4√3km or 6.9282Km

Therefore , the solution of the given problem of equation comes out to be y = (-1/5)x + 4 is the required equation.

The equivalent sign (=) is used in arithmetic equations to signify the equality of two propositions. It is shown that it is possible to compare various numerical factors by using mathematical techniques, which have served as manifestations of reality. For instance, the equal sign divides the number 12 even the solution y + 6 = 12 in two distinct portions. How many characters also are present from either end of such a character can be calculated. Conflicting symbol readings are prevalent.

Here,

The given equation of line j is y+5=5(x+5) which can be rewritten in slope-intercept form as y = 5x + 20.

Since line k is perpendicular to line j, the slope of line k will be the negative reciprocal of the slope of line j. The slope of line j is 5, so the slope of line k will be -1/5.

We are also given that line k includes the point (5,3). We can use this point and the slope of line k to find the equation of line k using point-slope form:

y - 3 = (-1/5)(x - 5)

Simplifying and rearranging, we get:

y = (-1/5)x + 4

In 2004, as per the run, the distance to the nearest tenth of a mile is 3.11 miles.

The distance that Kenenisa Bekele of Ethiopia ran in 2004 is equal to 5,000 meters, which is equivalent to 3.11 miles to the nearest tenth of a mile. To calculate this distance, you can use a simple conversion formula.

To convert meters to miles, you need to divide the number of meters by 1609.34.

In this case, we would divide 5,000 meters by 1609.34, which gives us 3.11 miles.

=> 5000/ 1609.34 = 3.11 miles.

The solution to the system is (x,y) = (48,19).

To find the solutions to the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the two expressions for y equal to each other and solve for x:

2/3x−5 = 1/2x+3

Multiplying both sides by 6 (the least common multiple of 3 and 2) to clear the fractions, we get:

4x - 30 = 3x + 18

Simplifying, we get:

x = 48

Now that we know x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:

y = 2/3(48) - 5 = 19

So the solution to the system is (x,y) = (48,19).

Company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants. The solution has been obtained by using linear equation.

What is a linear equation?

The degree of the linear equation is 1. It is very clear that linear equations with exponents greater than one lack variables. The equation for this graph yields a straight line.

Let S be the bags of seedlings, G be for general potting, and H be for hardwood plants.

It is given that each bag of seedling soil needs 2 units of sand, each bag of general soil needs 1 unit of sand, and each bag of hardwood soil needs 2 units of sand. We have 450 units of sand.

So, from this we get

2S + G + 2H = 450      ...(1)

Similarly, for units of loam and peat moss, we get the equations as

S + 2G + 2H = 450      ...(2)

S + G + 2H = 360         ...(3)

Now, on subtracting (3) from (2), we get

G = 110

On substituting this, we get

2S + 2H = 360    ...(4)

S + 2H = 230    ...(5)

S + 2H = 250    ...(6)

Now, we subtract (2) from (1), we get

S = 130

On substituting this in equation (5), we get

130 + 2H = 230

2H = 100

H = 50

Hence, company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants.

Step-by-step explanation:

The value decreases by 23% from,400 to 308 in 1 year. so if this continues then the equation would be y=400(0.77)^x.

The 0.77 comes from decaying 23%, meaning 1-0.23 = 0.77

The two shorter sides are 52 cm in length

The two longer sides are 1.5 times the length of the shorter sides

[tex] \sin(2 \alpha ) = 2 \sin( \alpha ) \cos( \alpha ) [/tex]

To find sin(a),

[tex] \sin( \alpha ) = \sqrt{1 - \cos {}^{2} ( \alpha ) } [/tex]

[tex] \sin( \alpha ) = \sqrt{1 - (0.6) {}^{2} } [/tex]

[tex] \sin( \alpha ) = \sqrt{0.64} [/tex]

Since sin is negative in the interval (270,360)

[tex] \sin( \alpha ) = - 0.8[/tex]

Now we can find sin(2a)

[tex]2( - 0.8)(0.6) = - 0.96[/tex]

2. The identity for cos(2x) is

[tex]2 \cos {}^{2} (x) - 1[/tex]

We know cos x is 0.6 so we get

[tex] \tan(4x) = \frac{2 \tan(2x) }{1 - \tan {}^{2} (2x) } [/tex]

[tex] \tan(2x) = \frac{ \sin( 2x) ) }{ \cos(2x) } = \frac{ - 0.96}{ - 0.28} = 24[/tex]

So we end up getting,

[tex] \tan(4x) = \frac{2(24)}{1 - (24) {}^{2} } [/tex]

Yes, the given for-loop is an infinite loop.

The loop condition j < 1000 is based on the variable j, which is initialized to 0, but j is never incremented or modified inside the loop. Therefore, the condition j < 1000 will always be true, and the loop will continue to execute indefinitely.

Answer: Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.

Step-by-step explanation:

To estimate how many people to expect in the Fiction and Literature section on Sunday, we can assume that the proportion of visitors to each section remains the same as it was on Saturday.

First, we need to calculate the total number of visitors on Saturday:

433 (Youth Wing) + 335 (Social Issues) + 367 (Fiction and Literature) = 1135

Next, we can find the proportion of visitors to the Fiction and Literature section:

367 (Fiction and Literature) / 1135 (total visitors on Saturday) ≈ 0.323

We can use this proportion to estimate the number of visitors to the Fiction and Literature section on Sunday:

0.323 (proportion of visitors to Fiction and Literature) x 600 (total visitors on Sunday) ≈ 194

Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.
