Find the midpoint of the line segment with the given endpoint of (9,-1) , (0,7)

( , 3 )

to calculate the midpoint use the midpoint formula

midpoint = [ (9 + 0), (- 1 + 7)] = (, 3 )

27/220.  

Step-by-step explanation:

To get £2.50 Pita has to take two pound coins and one 50p coin.

The probability of picking £1 then £1 then 50 p =  3/12 * 2/11* 9/10

= 9/220.

The number of possible arrangements of  2 pounds and 1 50p

= £-£-50, £-50-£ and  50-£-£.

= 3

So the required probability = 3 * 9/220

= 27/220.
