Using the equation we know that the flowerbed is 2250 feet away from the hive.

A mathematical assertion that has an "equal to" symbol between two expressions with equal values is known as an equation.

As in 3x + 5 Equals 15, for instance.

So, let's say the flowerbed is feet away from the hive.

The bee travels directly from its hive at a speed of 20 feet per second to a flowerbed before returning at a speed of 12 feet per second.

Time = distance/speed

Therefore, the bee needed x/20 seconds to get to the flowerbed and x/12 seconds to fly back to the hive.

The bee spends a total of 20 minutes, or 2060 seconds, or 1200 seconds away from the hive. I

t spends 15 minutes, or 1560 seconds, at the flowerbed.

Consequently, the equation will be:

x/20 + x/12 + 900 = 1200

3x + 5x/60 = 300

8x = 60 * 300

8x = 18000

x =  18000/8

x = 22550

Therefore, using the equation we know that the flowerbed is 2250 feet away from the hive.

The approximation of the area of the region R is 182.8125

Given:

y = x^3

from [2,5] using 6 subdivisions

deltax = (5 - 2)/6 = 3/6 = 0.5

hence the subdivisions are:

[2, 2.5]; [2.5, 3]; [3, 3.5]; [3.5, 4]; [4, 3.5]; [4.5, 5]

hence the right endpoints are:

x1 = 2.5; x2 = 3; x3 = 3.5; x4 =4; x5 = 4.5; x6 = 5

now the area is given by:

A = deltax*[2.5^3 + 3^3 + 3.5^3 + 4^3+ 4.5^3 + 5^3]

A = 0.5*365.625

A = 182.8125

The area using the Right Endpoint approximation is 182.8125.

A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.

Here, we

Let

x = the number of adult tickets sold

y = the number of senior tickets sold

483 people paid admission => a total of 483 tickets were sold and

x + y = 483

the total receipts were $7548

24x + 12y = 7548

by solving the system of equations

x + y = 483....(1)

24x + 12y = 7548....(2)

From equation (1), we get

x = 483-y....(3)

Now, we put the value of x in equation (2) and we get

24(483 - y) +12y = 7548

11592 - 24y + 12y = 7548

12y = 4044

y = 337

Now, we put the value of y in equation (1) and we get

x = 483 - 337

x = 146

Here we have to find the a6the term of the geometric sequence.

Data given:

The series = 512/243, -128/81, 32/27.....

The formula to find the nth term of the geometric sequence:

[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]

where [tex]a_{n}[/tex] = nth term of the sequence

a = first term of the sequence

r = common ratio

common ratio(r) = -128/ 81 ÷ 512/ 243

The theorems used are:

First blank: side-angle-side theorem

Second blank: CPCTC

Third blank: 200 feet

Fourth blank: 1,700 feet.

Wen two triangles have a pair of included congruent angles and two pairs of corresponding congruent sides, then both triangles are congruent to each other by the side-angle-side theorem.

Furthermore, if two triangles are known to be congruent to each other, the CPCTC states that "corresponding parts of corresponding triangles are congruent". This means all angles and all sides that corresponds to each other are congruent.

Therefore:

Using the side-angle-side theorem it can be shown that the two triangles are congruent to each other.

Then using CPCTC , the length of the road from the intersection to the first turn would be 200 feet.

The total length of the tour would be = 2(200 + 300 + 350)

Using, SAS it can be shown that the two triangles formed are congruent. Then using ,-CPCTC the length of the road from the intersection to the first turn can be found to be 200 feet. Thus, the total length of the tour is 1,700 feet.

The SAS Triangle Theorem indicates that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

By the use of the corresponding parts of congruent triangles are congruent (CPCTC) rule, we can state that the missing side is 200 feet. If that is the case, then the total distance traveled can be obtained by adding all the lengths of triangles:

=200 + 200 + 300 + 350 + 350 + 300

What is a rectangle?

A rectangle is a quadrilateral with all four interior angles 90°.

Given that the area of the rectangular field is 800 m².

Let the length and the width of the rectangle be x and y.

Then, the area of the rectangle is:

A= xy

Or, xy = 800

x = 800/y     (1)

The perimeter of the triangle is:

2x +2y

Since the triangle is divided into three equal parts by fence, the total length of the fence is equal to the sum of the perimeter of the triangle and two times the length or width of the triangle.

Therefore, the total length of the fence is:

L = 2x + 2y + 2x

L = 4x +2y

Substitute x = 800/y into the above equation:

L = 4(800/y) + 2y

L = 3200/y +2y         (2)

Differentiate the equation with respect to y:

L' = -3200/y² +2

Substitute L'= 0 into the above equation:

0 = -3200/y² + 2

y² = 3200/2

y² = 1600

y = 400

Substitute y = 400 into equation (2):

L = 3200/400 + 2(400)

L = 8 + 800

L = 808

Hence, the shortest total length of the fence is 808 m.

The area of the rectangle in centimeter square is 2013 cm².

The area of a rectangle is the product of its length and width.

If the values of area and one of the sides of a rectangle is given the other one can be found by forming a suitable equation.

The length and width of the given rectangle can be written in cm as follows,

The length is given as 24 × 2.54 = 60.96 cm

And, the width is 13 × 2.54 = 33.02 cm

Now, the area of the rectangle can be obtained by taking the product of length and width as follows,

Area = 60.96 × 33.02

        = 2012.89

Which can be approximated as 2013 cm².

If X is a normally distributed random variable and X ~ N(μ, σ), then the z-score is:                              z = x−μ/ σ

The z-score indicates the number of standard deviations that the value x is above (right) or below (left) the mean μ. Values ​​of x greater than the mean have positive z values, and values ​​of x less than the mean have negative z values. The z-score of x is zero if x is equal to the mean.

The standard normal distribution is the normal distribution of standardized values ​​called z-scores. Z-scores are measured in units of standard deviation. For example, if the normal distribution has a mean of 5 and a standard deviation of 2, then the value 11 is 3 standard deviations above (or to the right of) the mean. Here's the calculation:

                      x = μ + (z)(σ)  

                         = 5 + (3)(2)

                         = 11

The standard normal distribution has zero mean and one standard deviation. The transformation

                                    z= x − μ/σ

gives the distribution Z ~ N(0, 1). The value x comes from a normal distribution with mean μ and standard deviation σ.

The next two videos explain what it means to have a "normal" distributed data set.

If X is a random variable and follows a normal distribution with mean µ and standard deviation σ, the rule of thumb states within 1 standard deviation of the mean.

About 95% of the x-values ​​lie between –2σ and +2σ of the mean µ (within two standard deviations of the mean).

About 99.7% of the x-values ​​lie between –3σ and +3σ of the mean μ (within 3 standard deviations of the mean) .

Almost all x-values ​​are within 3 standard deviations of the mean.

1) +1σ and -1σ have z-scores of +1 and -1 respectively.

2) +2σ and -2σ have Z-scores of +2 and -2 respectively.

3) +3σ and -3σ have Z-scores of +3 and -3 respectively.

The rule of thumb is also known as the 68-95-99.7 rule.

The exact value used to calculate the median; further decreasing the minimum value or increasing the maximum value will not change the median value. Therefore, the median does not use all the information in the data and is therefore shown to be less efficient than the mean or average, which uses all the values ​​in the data.

We can eliminate a variable by adding the two equations, doing that we will find the solution (4, 1.5)

Here we have the following system of equations:

-3x - 8y = -24

3x - 5y = 4.5

To eliminate a variable, we can simply add the two equations and the variable x will be eliminated, let's do that:

(-3x - 8y) + (3x - 5y) = -24 + 4.5

Grouping like terms we get:

(-3x + 3x) + (-8y - 5y) = -19.5

0 - 13y = -19.5

Now we can solve this for y:

y = -19.5/-13 = 19.5/13 = 1.5

To get the value of x, we need to replace the value of y in one of the equations:

-3x - 8*(1.5) = -24

-3x = -24 + 8*1.5

-3x = -12

x = -12/-3 = 4
