Answer:
r = 9
Step-by-step explanation:
Given that c varies directly as (r + 1) then the equation relating them is
c = k(r + 1) ← k is the constant of variation
To find k use the condition c = 8 when r = 3, then
8 = k(3 + 1) = 4k ( divide both sides by 4 )
2 = k
c = 2(r + 1) ← equation of variation
When c = 20, then
20 = 2(r + 1) ← divide both sides by 2
10 = r + 1 ( subtract 1 from both sides )
9 = r
Answer:
t ≤ 11 (or all values 11 or less)
Step-by-step explanation:
8t - 9 ≤ 79
<em>So, I am assuming you are trying to find the value(s) of "t".</em>
Add 9 to both sides.
8t ≤ 88
Divide 8 by both sides.
t ≤ 11
ANSWER
t ≤ 11
Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.
