Answer:

Step-by-step explanation:
Given:
Number of eclairs = 3
Number of humbugs = 
Number of mints = 
Therefore, total number of sweets in the jar is,

Now, probability of selecting a sweet to be humbug is given as:

Therefore, the probability that it is a humbug is
.
Answer:
44
Step-by-step explanation:
k=1: 2*1-4 = -2
k=2: 2*2²-4 = 4
k=3: 2*3²-4 = 14
k=4: 2*4²-4 = 28
-2 + 4 + 14 + 28 = 44
3x-6≤9
3x≤15
x≤5
so the answer is x≤5
Yes it is linear since it's in the standard form Ax+By = C
A = 2
B = -8
C = 16
