Softa [21]
a.mean
Add all the numbers together and then divide by how much numbers there are in total
(10+18+21+55+48+23+24+25+32+43+10 )÷11
=309÷11
=28.1
b.median
Put the numbers in order then find the middle number.
10, 10, 18, 21, 23, 24, 25, 32, 43, 48, 55
the middle number is 24, so the median is 24.
c.mode
Since 10 occurs the most in the data, the mode is 10.

The Answer
10 Weeks
Step-by-step explanation:
180+170 = 350
17x10 = 170
Would take 10 weeks of saving 17 dollars a week to become equal to 350.
Percent formula : is/of = %/100
18 is what percent of 20...
is = 18
of = 20
% = x
sub and solve
18/20 = x/100
cross multiply
(20)(x) = (100)(18)
20x = 1800
x = 1800/20
x = 90 <=== so 18 is 90% of 20
