2/5 m - 1/5
Given:250 sheep in a 40-acre pasture.Number of sheep grazing in each acre.
250/40 = 6.25 or 6 sheep per acre
n = 6sample proportion: signified by ρSample 1: 4 → 4/6 = 0.67Sample 2: 1 → 1/6 = 0.17Sample 3: 9 → 9/6 = 1.50
multiply the sample proportion by 1-ρSample 1: 0.67(1-0.67) = 0.67(0.33) = 0.2211Sample 2: 0.17(1-0.17) = 0.17(0.83) = 0.1411Sample 3: 1.50(1-1.5) = 1.5(-0.5) = -0.75
divide the result by n. n = 6Sample 1: 0.2211/6 = 0.03685Sample 2: 0.1411/6 = 0.02352Sample 3: -0.75/6 = -0.125
square root of the quotient to get the standard error.Sample 1: √0.03685 = 0.1919Sample 2: √0.02352 = 0.1534Sample 3: √-0.125 = invalid
z value 95% confidence 1.96.
Sample 1: 1.96 * 0.1919 = 0.3761 or 37.61% margin of errorSample 2: 1.96 * 0.1534 = 0.3007 or 30.07% margin of error
I am pretty sure you would do 396x.25 on a calculator and then do that answer and x's it by 3 and that equals 297

Answer: 10-pound bag for $4.58
Step-by-step explanation:
A store sells potatoes in 5-pound bags for $2.29. To get the amount for a pound bag of potatoe, we divide $2.29 by 5. This will give:
$2.29 / 5 = $0.458
To get the amount equivalent goes thus:
For a 20-pound bag for $8.80, a pound will cost:
$8.80/20 = $0.44
For a 2-pound bag for $1.02, a pound bag will be:
$1.02/2 = $0.51
For a 10-pound bag for $4.58, a pound bag will cost:
$4.58/10 = $0.458
For a 7-pound bag for $3.01, a pound bag will cost:
$3.01/7 = $0.43
From the figures calculated, a 10-pound bag for $4.58 is the same as the amount calculated.
