Leni [432]

Firstly, order the two data set from smallest to largest as shown in diagram below

The value of median, Q2 is the 5th value of both set
The value of Q1 and Q3 is the first and third quarter of the set
The range of data set one is 5-2=3 and of set two is 12-1=11
The interquartile range of set one is 5 - 2 = 3
The interquartile range of set two is 5 - 1.5 = 3.5

The box plot is not symmetrical for either data set

If the world’s population is increasing at an annual rate of 1.3%, and there were 5 billion people in the year 1986, then in wha

Sliva [168]

5 billion * ( 1 + 0.013 ) ^x = 10 billion
1.013 ^x = 10 : 5 = 2
$x = log_{1.013}2$
x = 54
1986 + 54 = 2040
In the year 2040 the world`s population will be 10 billion.

Use completely the square to solve for x in the equation (x+7)(x-9)=25

ra1l [238]

You mean "completing the square," don't you? ;)

<span>(x+7)(x-9)=25 can be expanded: x^2 - 9x + 7x - 63 + 25, which becomes

x^2 -2x = 38.

Let's now complete the square:

x^2 - 2x + (1)^2 - (1)^2 = 38, or x^2 - 2x + 1 = 39

Rewrite that as (x-1)^2 = 39

Take the sqrt of both sides: x-1 = plus or minus sqrt(39)

Write the roots: x = 1+sqrt(39) and x = 1 = sqrt(39) (answers)</span>

En el numeral 87.684 la cifra de las decimas es la cifra de las centésimas es la cifra de las milésimas es la parte entera de la

rodikova [14]

Answer:

La cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.

Step-by-step explanation:

Para responder la pregunta, se debe descomponer el número en cuestión:

87.684

8 = Indica la cantidad de decenas del número, es decir, 8 decenas (80).

7 = Indica las unidades dentro de la decena, es decir, 7 unidades más que 80.

.6 = Indica la cantidad de decenas del entero.

.08 = Indica la cantidad de centésimas del entero.

.004 = Indica la cantidad de milésimas del entero.

Así, la cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.
