What is the median? 0.8 1.0 2.7 2.8 3.1 13.3
Answer:
2.75
Step-by-step explanation:
The median is just the middle number in the number set. So, you put the numbers in order (which they already are), and find the middle number. If there are two numbers in the middle (which only happens if there is an even amount of numbers), then you add both of them and divide by 2 (which we must do in this problem).
0.8, 1.0, 2.7, 2.8, 3.1, 13.3
(2.7 + 2.8)/2
(5.5)/2 = 2.75
So, the median is 2.75.
Hopefully this helped, good luck!
Step-by-step explanation:
Arranging the numbers in an ascending order:
0.8 1.0 2.7 2.8 3.1 13.3
Median = (3rd value + 4th value) / 2
[tex] = \frac{2.7 + 2.8}{2} \\ = \frac{5.5}{2} \\ = 2.75[/tex]

Answer:
448.25(2dp)
Step-by-step explanation:
1. Find the are of the entire rectangle:
length x breadth = 38 x 28 = 1064mm^2
2. Find the area of one semicircle
([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2
3. Multiply the area by 2
307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]
4. Subtract the area of the 2 semicircles from the area rectangle
1064-615.75 = 448.25 (2dp)

Determina el perimetro de las figuras geometricas que forman la rayuela
Perimetro: L=50 cm
Expresión:
Sustitucion:
P=_______/
La figura es un cuadrado y cada lado mide 50 cm
Answer:
2000cm
Step-by-step explanation:
Rayuela es un juego jugado por niños que se compone de 10 cuadrados.
Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm
La fórmula para el perímetro de un cuadrado es 4a
Donde a = longitud del lado
El perímetro de 1 cuadrado =
4 × 50 cm
= 200cm
El perímetro de los cuadrados totales en la rayuela.
1 cuadrado = 200 cm
10 cuadrados = x
Multiplicar cruzada
x = 10 × 200 cm
x = 2000 cm
Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.

What is 2 1/2 x 5 as a fraction and how
Answer:
12.5
Step-by-step explanation:
2 1/2 or 2.5 (in decimal form) times 5 equals 12.5
By multiplication of numbers, The solution of the expression 2 1/2 × 5 in form of a fraction is,
⇒ 2 1/2 × 5 = 25 / 2
What is mean by Multiplication?The multiplication of numbers means to add or sum a number to itself a particular number of times. And, The Multiplication can be viewed as a process of repeated addition.
We have to given that;
The expression of the multiplication is,
⇒ 2 1/2 × 5
Now, We can multiply the numbers as;
Here, The expression of the multiplication is,
⇒ 2 1/2 × 5
Change into improper form;
⇒ 5/2 × 5
⇒ 5 x 5 / 2
After multiply the numbers as;
⇒ 25 / 2
Therefore, By multiplication of numbers, The solution of the expression 2 1/2 × 5 in form of a fraction is written as,
⇒ 2 1/2 × 5 = 25 / 2
