Answer:

[tex]Remainder = 1956[/tex]

[tex]Quotient = 5[/tex]

Step-by-step explanation:

Given

[tex]Dividend = n[/tex]

[tex]Divisor = 10000[/tex]

[tex]Quotient = 1[/tex]

[tex]Remainder = 2011[/tex]

Required

Determine the quotient and remainder when the divisor is 2011

First, we need to determine the value of n.

The relationship between the given parameters is:

[tex]Dividend = Quotient * Divisor + Remainder[/tex]

Substitute values in the above:

[tex]n = 1 * 10000 + 2011[/tex]

[tex]n = 10000 + 2011[/tex]

[tex]n =12011[/tex]

So, we divide 12011 by 2011 and record the quotient and divisor:

[tex]\frac{12011}{2011} =[/tex]

The integer division of 12011 and 2011 is 5.

The remainder is calculated using:

[tex]Dividend = Quotient * Divisor + Remainder[/tex]

Where

[tex]Dividend = 12011[/tex]

[tex]Quotient = 5[/tex]

[tex]Divisor = 2011[/tex]

So, Remainder =:

[tex]Remainder = 12011 - 2011* 5[/tex]

[tex]Remainder = 12011 - 10055[/tex]

[tex]Remainder = 1956[/tex]

Hence:

[tex]\frac{12011}{2011} = 5\ Remainder\ 1956[/tex]

What is the average of a set of numbers?

An average is a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.

Given

September, $28.95;

October, $46.15;

November, $68.46;

December, $109.34;

January, $115.26;

February, $94.19;

March $75.66;

April, $51.97; and

May, $49.16.

Step two:

Total amount= 28.95+46.15+68.46+109.34+115.26+94.19+75.66+51.97+49.16= 639.14

Total number of monts= 9

Average= 639.14/9

Average= $71.01

Step-by-step explanation:

Let the midpoint formula be expressed as;

M(X,Y) = {x2+x1/2, y2+y1/2}

X = x2+x1/2

Y = y2+y1/2

Get x2

-3 = x2 + 1/2

-6 = x2 + 1

x2 = -6-1

x2 = -7

Get y2;

Y = y2+y1/2

8 = y2+6/2

16 = y2+6

Y2 = 16-6

y2 = 10

hence the coordinate of B is (-7, 10). Option A is correct

4x^2-4xy-3\frac{y^2}{2}x^2-5xy-3y^2 is 2

−3x^2 y^2 +8x^2 −18xy−6y^2

Step-by-step explanation:

Yes, the given table shows a proportional relation with constant of proportionality  1/3.

Two variables x and y are in proportional relation if the relation between  then is in the form y = k x, where k is the constant of proportionality.

Or we can say for all pairs ( x, y ) , y/x = k , k is constant then the table containing (x, y) values shows a proportional relationship.

From given table

When x= 5 , y =[tex]1\frac{2}{3}[/tex] =5/3

Then, y/x = (5/3)/5 = 1/3 =k

When x =6 , y =2

Then, y/x = 2/6 = 1/3 =k

When  x =  7 , y = [tex]2\frac{1}{3}[/tex] = 7/3

Then, y/x = (7/3) /7 = 1/3 =k

When x=8 , y =[tex]2\frac{2}{3}[/tex] = 8/3

Then , y/x = (8/3) / 8  = 1/3 =k

Thus for each pair (x, y) given in the table the ratio y/x is same , this ratio is say k = 1/3

Therefore, for the given table y/ x = k or y =k x with k = 1/3 , and the table  shows a proportional relation with constant of proportionality  1/3.

Answer:

7) 75.4 yd

8) 34.56 mi

6) 81.68 cm

Step-by-step explanation:

The formula of circumference is: circumference (C) = 2 * π * r

7) The radius = 12 yd

π = 3.14

We can solve for C:

C = 2πr

C = 2(3.14)(12 yd)

C = 75.4 yd

8) The radius = 5.5 mi

π = 3.14

Solve for C:

C = 2πr

C = 2(3.14)(5.5 mi)

C = 34.56 mi

6) The diameter is 26. The radius is one half of the diameter; so the radius is 13.

We can solve for C:

C = 2πr

C = 2(3.14)(13 cm)

C = 81.68 cm

El orden de forma creciente de los números enteros es:

-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32

Step-by-step explanation:

Ordenar de forma creciente números enteros implica ordenarlos de menor a mayor. Esto es, debes considerar primero el número que posea el menor valor y luego ir ordenándolos a medida que su valor vaya aumentando, para dejar en último lugar al que posea el mayor valor.

Para ordenarlos debes tener en cuenta que:

Entonces, en este caso el orden de forma creciente de los números enteros es:

Answer:

Step-by-step explanation:

The probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).

It is a branch of mathematics that deals with the occurrence of a random event.

There are four possible outcomes when flipping an unfair coin twice, since each coin flip has two possible outcomes (heads or tails).

We can use H to represent heads and T to represent tails.

The possible outcomes are:

HH (both flips are heads)

HT (first flip is heads, second flip is tails)

TH (first flip is tails, second flip is heads)

TT (both flips are tails)

Each of these outcomes has a certain probability associated with it.

Since the probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).

Hence, the probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).
