Should be one of the squared answers as x try plugging it back into the original equation
Answer:
Standard deviation = 8.27 percent
Step-by-step explanation:
Average = (Σx)/N
The average is the sum of variables divided by the number of variables.
x = each variable
N = number of variables = 5
Let the unknown percent be y
6 = (8 - 3 + 12 + 17 + y)/5
y = 30 - 34 = - 4
The standard deviation is the square root of variance. And variance is an average of the squared deviations from the mean.
Mathematically,
Standard deviation = σ = √[Σ(x - xbar)²/N]
x = each variable
xbar = mean = 6 percent
N = number of variables
σ = √[{(8 - 6)² + (-3 - 6)² + (12 - 6)² + (17 - 6)² + (-4 - 6)²}]/(5)]
σ = √[[(2)² + (-9)² + (6)² + (11)² + (-10)²]/(5)]
σ = √[(4 + 81 + 36 + 121 + 100)/(5)] = √(342/5) = 8.27 percent.
Peter dog ate 2.4 kilograms of dog food in 8 days
<u>Solution:</u>
Given that peters dog eats 0.3 kilograms of dog food each day
To find: amount of dog food eaten by peter dog in 8 days
From given question,
one day = 0.3 kilograms of food
Let "x" be the amount of dog food eaten by peter dog in 8 days
<em><u>Then for 8 days:</u></em>
amount of dog food eaten in 8 days = amount of dog food eaten in 1 day x 8

On multiplying we get,
x = 2.4
Thus peter dog ate 2.4 kilograms of dog food in 8 days
