Answer:
Median is 18.
Mean is 22.
Step-by-step explanation:
Median has to be ordered from least to greatest:
1, 9, 17, 18, 25, 41, 43
then the median is the number in the middle, which is 18.
Mean is the sum of all the numbers, divided by 7 (because there are 7 numbers given)
25+18+9+1+43+17+41= 154
154/7 = 22
Answer:
Range = (237100, 292900)
Step-by-step explanation:
Using Chebyshevs Inequality:






Thus, 88.9% of the population is within 3 standard deviation of the mean with the Range = μ ± kσ
where;
μ = 265000
σ = 9300
Range = 265000 ± 3(9300)
Range = 265000 ± 27900
Range = (265000 - 27900, 265000 + 27900)
Range = (237100, 292900)
Fraction adding: Okay, so if you have two fractions with the same denominator like 2/3 and 1/3 then they are easily added. Just add the numerators together and then keep the denominator. Like this: 2/3 + 1/3 = 3/3 or 1 whole. Here is something for fractions with unlike denominators.
