Step-by-step explanation:
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]
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
