Describe and correct the error in finding the median of the data 63,55,49,58,50,59,51

Afina-wow [57]

$\huge\text{Hey there!}$

$\large\text{When you see or hear the word \underline{median} think of its asking you}\\\large\text{\underline{what number is in the MIDDLE?} or it’s asking for the \underline{middle number}}$

$\large\text{Some people can easily find the median by putting your given numbers}\\\large\text{from least (smallest) to greatest (biggest)}}$

$\large\text{49, 50, 51, 55, 58, 59, 63}$

$\large\text{Make sure that you have the SAME amount in each sides of your numbers}$

$\large\text{The median in this given set seems to \underline{55} because it has 3}\\\large\text {numbers on each sides of it.}$

$\boxed{\boxed{\large\text{Answer: \huge \bf 55}}}\huge\checkmark$

Mr. King has 36 pair of shoes. 3/4 of them are gym shoes, how many of his shoes are gym shoes

Alex777 [14]

Answer:

The number of pair of gym shoes does Mr. king has is 27 pairs .

Step-by-step explanation:

Given as :

Total number of pairs of shoes does king has = 36 pairs

The number of gym shoes = $\dfrac{3}{4}$ of the total pairs of shoes

Let The number of pair of gym shoes = n

<u>According to question</u>

The number of gym shoes = $\dfrac{3}{4}$ × the total pairs of shoes

Or, n = $\dfrac{3}{4}$ × 36

i.e n = $\frac{3\times 36}{4}$

Or, n = 3 × 9

∴ n = 27

So, The number of pair of gym shoes = n = 27 pairs

Hence, The number of pair of gym shoes does Mr. king has is 27 pairs . Answer

i need help with this questions asap please. A grocery clerk is making a display of oranges. The numbers of oranges in the layer

ahrayia [7]

Answer:

If there is 1 at the top, then you have 1, then 2, then 3, etc.

total number of oranges equals:

1 + 2 + 3 + ... + 16 + 17 + 18 <-- stop at 18 because this is the number of oranges at the base

You can use the formula:

sum of first n numbers = n*(n + 1)/2

-->

18*19/2 = 9*19 = 171

or you can figure it out (basically derive the above formula):

you have:

1 + 18 = 19

2 + 17 = 19

3 + 16 = 19

...

How many pairs do you have? Well, it's just the number of numbers: 1-18 = 18 numbers (divide by 2) = 9 pairs)

9 pairs of 19 = 9 * 19 = 171

Hope this helps!
