Answer:
d
Step-by-step explanation:
Represent as
w=wally
a=ashan
so wally has 2 more marbles than ashan
w=2+a
together they have 88
w+a=88
since w=2+a, subsitute (2+a) for w in the w+a=88 equation
2+a+a=88
add like terms
2+2a=88
subtract 2 from both sides
2a=86
divide by 2
a=43
ashan has 43 marbles
No, you can't. Here's two different data sets with a mean of 123:
{3, 33, 333}
{122, 123, 124}
The range of the first set is 330, and the range of the second set is 2. These are very different ranges, so you can't assume that the ranges of the two data sets are about the same.
