The answer should be (x, y) —> (x - 8, y + 10)
4 boxes of chocolates are needed by the group.
If a group of 3 people are together, needing 8 chocolates each. This means that the total number of chocolates needed is 8 × 3 = 24.
Again, we are told that each box contains 6 chocolates. This means that to get the number of boxes needed, we have to divide the total number of chocolates needed by the number of chocolates per box.
Essentially, 24/6 = 4 boxes of chocolates

Answer:
0.0001899
Step-by-step explanation:
Total number to be selected from= 22
The number to be chosen for the event in an ordered sample is 5 from 22 people= 22C5
Where 22 Is the total number of possibilities and 5 is the no of selection
22C5= 22!/(22-5)!5!
= 22!/17!5!
= 22*21*20*19*18*17!/17!*5!
22*21*20*19*18/5*4*3*2*1
=22*7*19*9
=26334
If there is exactly 5 young people in the population, the probability will be 5/22C5
=5/26334
=0.0001899.
Answer:
Hello your question is incomplete attached below is the complete question
answer: RS = ST ( option b )
Step-by-step explanation:
First we consider Δ SCA and Δ TCB
∠ SCA = ∠ TCB , ∠CAS = ∠CBT = 90°
if we assume RS = ST then ΔSRT will be termed an Isosceles triangle with its legs : SR = ST. also vertex S bisects the base of the triangle.
Δ SBR ≅ ΔSBT from here we can deduce that ; BR = BT
From the assumptions what is actually missing to contrast the proof is : RS = ST
