Hello!

To find the interquartile you first have to find the median

20, 25, 30, 40, 40, 48, 50, 62

The median is 40

To find quartile 1 you find the median of the numbers less than 40

20, 25, 30

Quartile 1 - 25

To find quartile 3 you find the median of the numbers higher than 40

48, 50, 62

Quartile 3 - 50

The answers are
Quartile 1 - 25
Quartile 3 - 50

Hope this helps!

A farmer picked 600 portugals and oranges in total to be sold to the market. There are 3 times as many oranges as there are port
max2010maxim [7]

Answer:

450 portugals

Step-by-step explanation:

in this question, we are tasked with calculating the number of portugals which are picked by the farmer

Firstly, let the number of portugals picked be p and the number of oranges picked be r.

Thus;

p + r = 600 ••••••••••(i)

Secondly there are 3 times as many oranges as there are portugals;

That would be;

3 * r = p

3r = p. •••••••••(ii)

substitute ii into i

3r + r = 600

4r = 600

r = 600/4

r = 150

P = 3r

p = 3 * 150 = 450
