Considering the definition of an equation and the way to solve it, the number of points Carlos scored in the last game is 19.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being:

and knowing that in the last game, Fabio had 7 points less than 2 times as many points as Carlos, the equation to determine the number of points Carlos scored in the last game is:

2C - 7= F

Fabio scored 31 points in the game. So you get:

2C - 7= 31

Solving:

2C= 31 + 7

2C= 38

C= 38 ÷ 2

C=19

Finally, the number of points Carlos scored in the last game is 19.

Step-by-step explanation:

The 65-th percentile is  approximately 83.8 ounces.

A number at or below which a particular percentage falls in its frequency distribution, or a score below which a given percentage falls, is known as the k-th percentile in statistics. The 50th percentile, for instance, is the score at or below which 50% of the distribution's scores can be found.

The percentile can be calculated by using the formula

Percentile Value = μ + zσ  where

z is the z-score , μ is the mean and σ is the standard deviation.

Here the percentile that is to be calculated is 65.

So we take the value that is closest to 0.65 from the z-table.

We get the value of the data to be 0.39

Now putting the values in the equation we get:

Percentile Value = μ + zσ  

or, Percentile Value = 83 + (0.39 × 2)

or, Percentile Value = 83.78

or, Percentile Value ≈ 83.8

Hence the 65th percentile value of the function is given by 83.8  .

We need to know about domain and range of a graph to solve this problem. The domain is (-∞,5) and the range is (-∞,2).

The domain of a function is the input values that the function can take. The range is the set of values that can be the possible output of the function. The domain of a graph are the values that are on the x-axis and the range is on the y-axis. The arrow means that the graph goes on till infinity, a solid sphere means that the graph ends at that point and the ending point is included in the function, a hollow sphere means the graph ends at that point and the ending point is not included in the function. In the graph in the question, along x-axis the values on left goes on till negative infinity and on right the domain is open at 5. For range along y-axis, the range on the left side goes on till negative infinity and on the right it is open at 2.

The value of x is 27

In this question, we have been given a line AB and a point O on the line AB.

From figure we can see that, there are linear angles ∠AOM, ∠MON, and ∠NOB

Also, ∠AOM = 36°,

∠MON = 90°, and

∠NOB = 2x

We need to find the value of x.

We know that the sum of linear angles is 180°

⇒ ∠AOM + ∠MON + ∠NOB = 180°

⇒ 36° + 90° + 2x = 180°

⇒ 126° + 2x = 180°

⇒ 2x = 180 - 126°

⇒ 2x = 54°

If three points (2,4), (6,3), (10,2) are correct, the line -4y = x - 18 will appear.

If all the three points are plotted correctly then the line obtained will be -4y = x - 18.

The form of equation of line is the slope intercept form of line. In this form of line, the line is represented with the slope of line and the intercept of the y axis.

By using the equation of the line, all the three correct points can be found out easily,

By assuming any three values of x, we can find the value of y.

1. Let us assume x = 2.

Putting value of x we get,

-4y = 2 - 18

-4y = -16

y = 4.

So, the first point is (2,4).

2. Let us assume x = 6.

Putting value of x we get,

-4y = 6-18

-4y = -12

y = 3.

So, the second point is (6,3).

3. Let us assume x = 10.

Putting value of x we get,

-4y = 10-18

-4y = -8

y = 2.

So, the third point is (10,2).

The length and the widths are 420.031 yards and 0.031 yards if a rectangular parking lot has a length that is 420 yards greater than the width.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

Let L be the length and W be the width of the rectangle.

From the question:

L = 420 + W (based on the data given in the question)

LW  = 13

(420 + W)W = 13

W² + 420W - 13 = 0

After solving the above quadratic equation:

W = 0.031, W = -420.03 (width cannot be negative)

W = 0.031 yards (which is not practical but from a mathematical point of view it can be considered)

L = 420 + 0.031 = 420.031 yards

Thus, the length and the widths are 420.031 yards and 0.031 yards if a rectangular parking lot has a length that is 420 yards greater than the width.

Answer:

x= -9/5

Step-by-step explanation:

I hope this helps!

The answers to all the parts of the question are:

(A)  Before we begin, consider the cartesian plane, where the x-axis represents the cover charge and the y-axis represents the number of guests per night.

According to the previous information, we will find the following coordinates there: (9,165)  (10,150).

Remember that the linear equation's slope-intercept form is y=mx+b, where m is the slope and b is the intercept.

The slope can be calculated using the following formula:

In this case, the first coordinate will be (9,165) and the second will be (10,150).

The order is irrelevant.

Finally, we get the same value for m.

So,

We now have the slope and two points. Find a linear demand equation using this formula and remember that the point-slope form of a line's equation is y - y1 = m(x - x1).

Any of two coordinates can be selected.

In this case, we will select the second one.

We can choose between two coordinates.

In this case, we'll go with the second option.

Solve equation (1) for y:

We defined x as the cover charge (p) and y as the number of guests above (q).

As a result, rewrite equation 1.

Its formula depicts the number of guests per night as a function of the cover charge.

(B) The nightly revenue can be calculated by multiplying the cover charge price by the number of guests.

So we simply multiply the equation 1 by p.

(C) To calculate the nightclub's cost function, multiply the cost of two non-alcoholic drinks by the number of guests (equation 1) and add nightly overheads.

(D) To calculate the profit in terms of the cover charge, subtract the nightly costs (equation 3) from the nightly revenue (equation 2).

We will use the first derivative test (y'(x)=0) to find an extremum point to determine the entrance fee we should charge for maximum profit.

P's first derivative should be computed (p)

P'(p) = -30p + 330 = 0

30p = 330

p = 330/30

p =  $11

For maximum profit, the entrance fee should be p=$11 per guest.

Answer:

t = d/r

Step-by-step explanation:

d = rt

We are solving for t, so you need t alone on the left side.

Switch sides.

rt = d

t is being multiplied by r, so you need to divide the left side by r to get rid of r. You must do the same operation to both sides of an equation, so divide both sides of the equation by r.

rt/r = d/r

rt/r is simply t, so we get:

t = d/r

Part (a)

S1 = 1/2 since we only have one term, i.e. we aren't really summing anything here.

S2 = (1/2) + (1/4) = (2/4) + (1/4) = (2+1)/4 = 3/4

S3 = (1/2) + (1/4) + (1/8) = (4/8) + (2/8) + (1/8) = (4+2+1)/8 = 7/8

Or,

S3 = S2 + 1/8 = (3/4) + (1/8) = (6/8) + (1/8) = (6+1)/8 = 7/8

S4 = S3 + 1/16 = (7/8) + (1/16) = (14/16) + (1/16) = (14+1)/16 = 15/16

S5 = S4 + 1/32 = (15/16) + (1/32) = (30/32) + (1/32) = (30+1)/32 = 31/32

Here's the summary:

=============================================================

Part (b)

Through trial and error, the formula is

Sn = ( (2^n) -1 )/(2^n)

For example, if n = 4, then,

Sn = ( (2^n) -1 )/(2^n)

S4 = ( (2^4) -1 )/(2^4)

S4 = (16 - 1)/(16)

S4 = 15/16

=============================================================

Part (c)

u1 = first term = 1/2

r = common ratio = 1/2

Sn = u1*( 1 - r^n)/(1 - r)

Sn = (1/2)*( 1 - (1/2)^n )/(1 - 1/2)

Sn = (1/2)*( 1 - (1/2)^n )/(1/2)

Sn = 1 - (1/2)^n

Sn = 1 - 1/(2^n)

Sn = (2^n)/(2^n) - 1/(2^n)

Sn = ( (2^n) -1 )/(2^n)

This helps confirm the formula mentioned in part b

=============================================================

Part (d)

As n gets very large, Sn approaches 1

Examples:

Try out larger values of n and the Sn value should get closer to 1.

The reason why this works is because Sn = (x - 1)/x where x = 2^n

The (x-1)/x is equivalent to 1 - (1/x) and the 1/x approaches zero when x gets larger. The x gets larger as 2^n does.

The value of Sn itself will never equal 1 exactly. It simply gets closer and closer.
