Answer: False
Step-by-step explanation:
Consider the number as 'n' (for now)
3n - 9 = 69
3n = 69 + 9
3n = 78
n = 78/3
n = 26
Therefore, The number is 26
Answer:
C) a positive correlation
Step-by-step explanation:
<em>More people ⇒ Longer time</em> is a positive correlation between those variables. However, <em>longer time</em> is not the desired outcome.
Rather, <em>shorter time</em> is the desired outcome. The correlation between <em>more people</em> and <em>shorter time</em> is negative. In order to compute that correlation numerically, one would have to define a function that would give a numerical value for "shorter time" that would model the goodness of outcome as time gets shorter.
Answer:
56 - 2b = a
Step-by-step explanation:
Step 1:
60 + 2a - 4 = 2b + 3a
Step 2:
56 + 2a = 2b + 3a
Step 3:
56 = 2b + a
Answer:
56 - 2b = a
