The answer is A. The sample space of an experiment or random trial is the set of all possible outcomes and results of that experiment, which means that they will be unique outcomes.
Consider the complete question is "A store has two different sizes of ice cream on sale this week. The smaller container costs $3.87 for 48 ounces. The larger container costs $6.42 for 128 ounces. which ice cream costs less per ounce?"
Given:
The smaller container costs $3.87 for 48 ounces.
The larger container costs $6.42 for 128 ounces.
To find:
Which ice cream costs less per ounce?
Solution:
We know that

Using this formula, we get
Per ounce cost of small container 


Per ounce cost of larger container 


Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
