Answer:

1891

Step-by-step explanation:

night 1: 4000 seats- 2950 seats= 1050 empty.

night 2: 4000 seats- 3159 seats= 841 empty.

1050+841= 1891 empty seats for the two nights.

Hope this helps! ;)

Answer:

total seats for two night= 4000*2=8000

seat occupied= 3159+2950= 6109

Total empty seat= 8000-6109=1891

Step-by-step explanation:

Remember to follow PEMDAS. Simplify the expression.

PEMDAS =

Parenthesis

First, distribute -5 to all terms within the parenthesis:

-5(y) = -5y

-5(1) = -5

Next, combine like terms:

-5y + 6y - 5

(-5y + 6y) - 5

1y - 5

1y - 5 is your answer.

Answer: D. The data are discrete because the data can only take on specific values.

Step-by-step explanation:

Discrete data refers to data that has a specific value in a specific period and so can be counted as opposed to continuous data that cannot be counted as it goes on to infinity. An example of continuous data would be the height of students in a class. This is continuous because a person's height could be 1.02325845...... metres.

The number of car accidents on a particular stretch of highway can be counted and the data can only take on a specific value thereby making it discrete data.

In this exercise we have to use the knowledge of distance to understand which the best alternative corresponds to car accidents, in this way we find that:

Letter D. The data are discrete because the data can only take on specific values.

Discrete information in visible form refers to data that bear a distinguishing value fashionable a distinguishing period accordingly can be check in order as opposite to continuous information in visible form that cannot be deem as it continue to infinity.

An instance of constant data hopeful the height of person actively learning fashionable a class. This is constant cause a person's crest could be 1.02325845 metres.

The number of vehicle driven on streets accidents in contact a particular stretch of heavily traveled maybe have importance and the data can only oppose a particular financial worth by that making it discrete information in visible form.

Answer:

Step-by-step explanation:

A complex number is a number that has both real and imaginary part. An example of a complex number is z = x+iy where x is the real part and y is the imaginary part.

If z = x+iy, the conjugate of z₁ will be x-iy

adding the complex number to its conjugate will give;

P = z+z₁

P = x+iy +(x-iy)

open the parenthesis

P = x+iy+x-iy

collect like terms

P = x+x+iy-iy

P = 2x

We can see that the resulting value does not contain the imaginary number i, hence the result is a real number.

Hence the result of adding a complex number to its conjugate is a REAL NUMBER

Taking the difference;

P =  = z-z₁

P = x+iy -(x-iy)

open the parenthesis

P = x+iy-x+iy

collect like terms

P = x-x+iy+iy

P = 0+2iy

P = 2iy

We can see that the resulting value contains the imaginary number i, hence the of taking their difference is a complex number.

Hence the result of subtracting a complex number from its conjugate is an IMAGINARY NUMBER

Answer:

89

Step-by-step explanation:

Given that

2 O, 2 T and 1 M

Now based on this, the following ways are there  

1

Three ways i.e. {M,T,O}

2

XX or XY

XX in 2C1 = two ways i.e. {OO or TT}

XY in 3C2 × 2! = six ways

3

XXY or XYZ

XXY in 2C1 × 2C1 × 3! ÷ 2! = twelve ways

XYZ in 3C3 × 3! = six ways

4

XXYY or XXYZ

XXYY = 4! ÷ (2! × 2!) = six ways

XXYZ in 2C1 ×  4! ÷ 2! = twenty four ways

5

= 5! ÷ (2! ×2!)

= 120 ÷ 4

= 30

Therefore, the total is

= 3 + (2 +6)+ (12 +6) + (6 +24) + 30

= 89

There are 30 different letter permutations.

The word is given as:
MOTTO

From the given word, we have the following parameters:

The number of different (d) letter permutation is then calculated as:

[tex]d = \frac{n!}{T!O!}[/tex]

This gives

[tex]d = \frac{5!}{2!2!}[/tex]

Evaluate each factorial

[tex]d = \frac{120}{2 \times 2}[/tex]

Evaluate the product of 2 and 2

[tex]d = \frac{120}{4}[/tex]

Divide 120 by 4

[tex]d = 30[/tex]

Hence, there are 30 different letter permutations.

Answer:

Interval                Slope  of secant lines

 [1,2]                            113.000

 [1, 1.5]                          75.000

 [1, 1.1 ]                           51.960

  [1, 1.01]                       47.482

 [1, 1.001]                       47.048

Step-by-step explanation:

From the question we are told that

   The  function is  [tex]f(x) =  16x^3 -x[/tex]

Now considering the intervals

  For  [1, 2]

The  slopes of secant lines is mathematically represented as

     [tex]\frac{ f(2) - f(1)}{2-1}  =  \frac{16(2)^3 - 2 - [16(1)^3 -1] }{2-1 }  =  113.000[/tex]

  For  [1, 1.5]

The  slopes of secant lines is mathematically represented as

     [tex]\frac{ f(1.5) - f(1)}{1.5-1}  =  \frac{16(1.5)^3 - 1.5 - [16(1)^3 -1] }{1.5-1 }  = 75.000[/tex]

  For  [1, 1.1]

The  slopes of secant lines is mathematically represented as

     [tex]\frac{ f(1.1) - f(1)}{1.1-1}  =  \frac{16(1.1)^3 - 1.1 - [16(1)^3 -1] }{1.1-1 }  = 51.960[/tex]

   For  [1, 1.01]

The  slopes of secant lines is mathematically represented as

     [tex]\frac{ f(1.01) - f(1)}{1.01-1}  =  \frac{16(1.01)^3 - 1.01 - [16(1)^3 -1] }{1.01-1 }  =47.482[/tex]

   For  [1, 1.001]

The  slopes of secant lines is mathematically represented as

     [tex]\frac{ f(1.001) - f(1)}{1.001-1}  =  \frac{16(1.01)^3 - 1.001 - [16(1)^3 -1] }{1.001-1 }  =47.048[/tex]

Answer:

85 + 86 = 171

Step-by-step explanation:

Just divide 171 by 2 = 85.5, so it pretty clear the rest is just logic.

Decomposers in a food web are organisms that break down dead or decaying organisms and turn them into simpler, inorganic materials, making nutrients available for primary producers. A rotten fruit is not completely wasted because it will go back into the dirt for a producer to use, and the food chain continues.
