Step-by-step explanation:

If Damien can get to 70% maximum ranking in 56 hours, then we can make this equation:

0.7x(representing 70%)=56 (Amount of time Damien has played)

0.7x=56

Divide 0.7 on both sides we get:

x=80

Damien will have to play 80 hours to get to 100% Rank.

Answer:

d = 114t

Step-by-step explanation:

distance = rate * time

therefore, rate = distance/time

684 ft in 6 sec = 114 ft per sec (this is the 'rate')

so the distance can be calculated by multiplying time in seconds to get distance in feet

d = 114t

To calculate the probability a) P = (4C4 x 3C3)/(12C12) = 1/12. (b) P = (4C1 x 3C3 x 5C5)/(12C12) = 1/12. (c) P= (4C1 x 3C3 x 4C3 x 5C4)/(12C12) = 1/9. (d) P= (4C2 x 3C3 x 5C5)/(12C12) = 1/36.

(a) To calculate the probability that all hip surgeries are completed before another type of surgery, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with four hip surgeries and three knee surgeries (4C4 x 3C3). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/12). (b) To calculate the probability that the schedule begins with a hip surgery, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with one hip surgery, three knee surgeries, and five shoulder surgeries (4C1 x 3C3 x 5C5). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/12). (c) To calculate the probability that the first and last surgeries are hip surgeries, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with one hip surgery at the start, three knee surgeries, three hip surgeries, and four shoulder surgeries (4C1 x 3C3 x 4C3 x 5C4). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/9). (d) To calculate the probability that the first two surgeries are hip surgeries, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with two hip surgeries, three knee surgeries, and five shoulder surgeries (4C2 x 3C3 x 5C5). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/36).

By using the box plots, each statistical value should be completed as follows;

Mean: cannot be determined.

Median: equal for data sets X and Y.

Range: greater for data set X.

Interquartile range: greater for data set Y.

Mathematically, the range of a data set can be calculated by using this formula;

Range of X = Highest number - Lowest number

Range of X = 65 - 20

Range of X = 45.

Range of Y = Highest number - Lowest number

Range of Y = 55 - 20

Range of Y = 35.

Mathematically, interquartile range (IQR) of a data set and it is typically calculated as the difference between the first quartile (Q₁) and third quartile (Q₃):

(iii) Two decimal places is 317.47 meters per minute.

(iv) Three significant figures is 317 meters per minute.

Note: To find the average velocity, divide the distance traveled by the time it took to travel that distance. 1500 meters / 4.67 minutes = 322.2 m/min. But since you want the answer rounded to different degrees, you can round the answer accordingly.

Answer:If at the end of any year a car is worth 5% less than what it was worth at the beginning of the year, we can say that the car's value decreases by a factor of 0.95 (1 - 0.05) every year.

To find the car's value in December 2009, we can use the formula:

Car value at end of year = Car value at beginning of year * (1 - 0.05)^(number of years)

Plugging in the given values, we get:

Car value in December 2009 = 10,000 * (1 - 0.05)^1 = 9,500

So the car's value in December 2009 is 9,500 dollars.

Step-by-step explanation:

Answer:

9500

Step-by-step explanation:

If you didn't understand that one (which I personally found a little complicated) the answer can be found like this.

1. You firstly find the decrease which is 5/100 × 10000 (5/100 can also be written as 5%) and the answer will be 500

2. Then you take the original value and you minus the loss in worth of the car —> 10000-500 = 9500

Using Pythagoras' theorem, we can conclude that we can put a 79.65 inches TV in the TV cabinet.

We have been given that a TV -cabinet is 64 inches long and 52 inches high.

After leaving 2 inches on all sides, our new dimensions would be:

Length = 66 - 2 - 2 = 66 - 4 = 62 inches

Height = 54 - 2 - 2 = 54 - 4 = 50 inches  

Using Pythagoras' theorem, we can find the diagonal of the television

Diagonal² = 62² + 50²

Diagonal² = 3844 + 2500

Diagonal² = 6344

Take square root of both sides:

Diagonal = √6344

Diagonal = 79.65 inches

Hence, we can put a 79.65 inches TV

The correct answer is option is option d) not exact but having an integrating factor x c e.

Integrating factor is defined as the function which is selected in order to solve the given differential equation. It is most commonly used in ordinary linear differential equations of the first order. When the given differential equation is of the form; dy/dx + P(x) y = Q(x)

We have, (x2+y2)dy= -xydx

⇒dxdy= -(x2+y2xy)

Substitute y=vx

⇒ - dxdy=v+xdxdv

⇒v+xdxdv= -(1+v2v)

⇒ xdxdv= -(1+v2v−v)

            = -(−1+v2v3)

⇒v31+v2dv =xdx

Integrating both sides we get, −2v21+logv= logx-logc, where c is constant

⇒−2v21+log(cvx)=0

⇒y=cex2/2y2

Now using y(1)=1⇒c=e−1/2

Also y(x0)=e

⇒e=e−1/2+x02/2e2⇒1=−1/2+x02/2e2

In the given simultaneous linear equation, the value for x is 3 and the value for y is 2.

A system of simultaneous linear equations is any set of two or more linear equations that share the same variables involved. Obtaining values for the unknown variables that simultaneously satisfy all of the equations is required to solve such a system.

In the given question,

x + y = 5.......(i)

x2 - 2y2 = 1.......(ii)

x = 5 - y.........(iii)

Substituting x in equation(ii) = (5 - y)2 - 2y2 = 1

25- 10y + y2 - 2y2 = 1

25 - 1 = y2 + 10y

y2 + 10y2 - 24 = 0

(y + 12)(y - 2) = 0

Then Either y + 12 = 0 or y - 2 = 0

= (-12, 2)

Thus, y = 2

Now, substituting the value of y in equation (i),

x + y = 5

x + 2 = 5

x = 5 - 2

x = 3

Therefore x = 3 and y = 2.

(x + 7)² = -4(y - 10)

The equation of a vertical parabola is given as follows:

(x - h)² = 4p(y - k)

In which:

A parabola can be drawn given a focus of (-7, 9), hence:

Directrix of y = 11, hence:

k - p = 11.

Adding the equations of the y-coordinate of the focus and of the directrix, the value of k is obtained as follows:

Let's call the length of the bottom side of the triangular banner "b". When Alice reaches her arm up above the ground, the height of the banner changes from its original height of "h" to a new height of "h'". The area of the banner can be calculated using the formula:

A = (b * h') / 2

The new height "h'", can be calculated using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).

In this case, the two shorter sides are the original height "h" and the difference between the length of Alice's arm and the original height, which we will call "d". The longest side is the distance between the two anchors, which we will call "a".

So:

h^2 + d^2 = a^2

We can solve for "d" using this equation:

d = sqrt(a^2 - h^2)

And then we can find "h'" using:

h' = h + d

So the area of the banner can be calculated as:

A = (b * (h + sqrt(a^2 - h^2))) / 2

The solution assumes that the banner is a right triangle, with one vertex at the top, one vertex at the bottom, and a straight side along the ground connecting the two bottom vertices.

A sphere, like a ball, is defined as a perfectly spherical geometrical entity in three dimensions.

the general equation of a sphere is (x – a)² + (y – b)² + (z – c)² = r² where (a, b, c) is the centre of the sphere and r is the radius of the sphere.

Given, the centre of the sphere C(−4, 2, 6) and radius of sphere 7 units

Equation of sphere: (x - (-4))² + (y - 2)² + (z - 6)² = 7²

                                   (x + 4)² + (y - 2)² + (z - 6)² = 49

It is given that the sphere is intersecting with yz - plane which means x = 0

so, (0 + 4)² + (y - 2)² + (z - 6)² = 49
