Step-by-step explanation:
From what I see in the problem, the expression is
To solve, plug in a and k.
3*5^2=75
(3*5)^-1 = 1/15
5^-2 = 1/25
1. The mean is calculated using:
(9.4 + 17 + 7.3 + 7 + 16.1 + 5.4 + 5.9 + 8.5 + 4.2 + 9.2)/ 10
= 9
2. The standard deviation is 4.31
3. The years are 1996, 1997, 1999-200
<span>c) 1996 and 1997

4. The median is 7.9
maybe 2/3 in fraction or .66666666666 in decimal
Answer:
