Answer:
A
Step-by-step explanation:
14/20=0.7 or 70% are soft-centred. If we take two candies we have three possibilities associated with probabilities:
Both soft-centred: 0.7²=0.49 or 49%
Both hard-centred: 0.3²=0.09 or 9%
One of each: 2×0.3×0.7=0.42 or 42%. 49+9+42=100%. So these are all the possible outcomes.
The number of the product is 9
5 pounds= 80 ounces
total cost= ($0.44×1)+($0.20×79)=$16.24
Is This Substitution?
Cause if it is, then Y = 3x - 4
Y = 4 + x
= (4, 8)
