Mean = Numbers added up and divided by the amount of numbers.
Mean = 45 + 90 + 18 + 53 + 13 + 38 + 22 + 59 + 49
Mean = 387 ÷ 9
Mean = 43
Median = The middle number when arranged in order
Median = 13, 18, 22, 38, 45, 49, 53, 59, 90
Median = 45
Mode = The number that occurs most often
Mode = There is no mode because each number occurs the same amount of times
Range = Biggest number takeaway smallest number
Range = 90 - 13
Range = 77
Answer:
r = -1 or r = 5/3
Step-by-step explanation:
(2k - 1)/(k + 1) = (3k + 1)/(2k - 1)
(2k - 1)^2 = (k + 1)(3k + 1)
4k^2 - 4k + 1 = 3k^2 + 4k + 1
k^2 - 8k = 0
k(k - 8) = 0
k = 0 or k = 8
For k = 0,
(2k - 1)/(k + 1) = -1/1 = 1
For k = 8,
(2k - 1)/(k + 1) = 15/9 = 5/3
Answer:
64
Step-by-step explanation:
Using the rule of logarithms
x = n , then
x = 
, thus
x = 3
x = 4³ = 64
