In this case...
the Largest (20) - smallest (0) = Range
Answer:
6.25 minutes or 375 seconds
Step-by-step explanation:
We can solve the following problem through the Proportion method.
Here,
we may take the time taken by the machine as x
Notice that the pattern is "previous term plus 2". This is an arithmetic sequence where the difference (d) equals +2
= a₁ + d(n - 1) ; where a₁ is the first term, d is the difference, and n is the term.
f(n) = 1 + 2(n - 1)
f(n) = 1 + 2n - 2
f(n) = 2n - 1
********************************
f(10) = 2(10) - 1
f(10) = 20 - 1
f(10) = 19
Answer:
see below
Step-by-step explanation:
8 can be factored from each of the terms of the sum. (It's the distributive property.)
8·0 + 8·1 + 8·2 + ... + 8·26 + 8·27
= 8·(0 +1 +2 + ... +26 +27)
