Using it's concept, the desired probability is given as follows:
P(decaf or sugar) = 0.41.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. A probability can also be represented as a proportion.
From the table, we have that:
- P(decaf) = 0.05 + 0.08 + 0.09 = 0.22.
Hence:
P(decaf or sugar) = 0.22 + 0.19 = 0.41.

Step-by-step explanation:
a2 = a1×r
a3 = a1×r²
a1×r + a1×r² = 6×a4 = 6×a1×r³
1.
r + r² = 6r³
6r³ - r² - r = 0
r×(6r² - r - 1) = 0
the first solution is obvious : r = 0.
but this is no useful ratio for a geometric sequence.
the other 2 solutions are in
6r² - r - 1 = 0
the general solutions for a quadratic equation are
(-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 6
b = -1
c = -1
so,
(1 ± sqrt(1 - 4×6×-1))/12
r = (1 ± sqrt(25))/12
r = (1 ± 5)/12
r1 = (1+5)/12 = 6/12 = 1/2
r2 = (1-5)/12 = -4/12 = -1/3
2.
we can ignore r2 (negative) and just focus on r1 (1/2).
the second term is 8. that means
a2 = 8 = a1×r = a1×1/2
a1 = 2×a2 = 16
so, we have
a1 = 16
a2 = 8
a3 = a2×1/2 = 8×1/2 = 4
a4 = a3×1/2 = 4×1/2 = 2
a5 = a4×1/2 = 2×1/2 = 1
a6 = a5×1/2 = 1×1/2 = 1/2
a7 = a6×1/2 = 1/2 × 1/2 = 1/4
Answer:
Plus 2 (+2)
Step-by-step explanation:
The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:
3 + 2 = 5
5 + 2 = 7
7 + 2 = 9
etc.

Answer:
We conclude that:
''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:
Step-by-step explanation:
Given the statement
''add 3 and the sum of 9 and v''
Let us break down the statement
so
Adding 3 and the sum of 9 and v will be: 3 + 9 + v
Therefore, we conclude that:
''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:
