Answer:
First term = -41.
Common difference = -15.
Step-by-step explanation:
nth term: an = a1 + (n - 1)d where a = first term and d = the common difference.
-671 = a1 + (43 - 1)d
-806 = a1 +(52 - 1)d
-671 = a1 + 42d
-806 = a1 + 51d
Subtracting ( to eliminate a1):
-671 - (-806) = 42d - 51d
-9d = 135
d = -15
Substitute for d in the first equation:
-671 = a1 + 42*-15
-671 = a1 - 630
a1 = -671 + 630 = -41.
Answer:
120:80 I think this is the answer
Step-by-step explanation:
$880, $896, $914, $925, and $963
median = $914
mean = (896+925+880+963+914)/5 = 4578/5 = $915.6
$915.6 - $914 = $1.6
so mean is greater than median $1.6
answer is B. second choice
<span>The mean is $1.60 greater.</span>
