The answer is 52.
Answer:
Design 3: An SRS of size 3000 from a population of size 300,000,000
Step-by-step explanation:
To check the SRS designs will give the most precision (smallest standard error) for estimating a population mean, we'll make use of the following formula:
V(y) = S²/n( 1 - n/N)
Where S² is a constant for the three SRS designs
Check the first design
n = 400
N = 4000
So, V(y) = S²/400 (1 - 400/4000)
V(y) = S²/400(1 - 0.1)
V(y) = 0.0025S²(0.9)
V(y) = 0.00225S²
V(y) = 2.25S²E-3
The second design
n = 30
N = 300
So, V(y) = S²/30 (1 - 30/300)
V(y) = S²/30(1 - 0.1)
V(y) = S²/30(0.9)
V(y) = 0.03S²
V(y) = 3S²E-2
The third design
n = 3,000
N = 300,000,000
So, V(y) = S²/3,000 (1 - 3,000/300,000,000)
V(y) = S²/3,000(1 - 0.00001)
V(y) = S²/3,000(0.99999)
V(y) = 0.00033333
V(y) = 3.33S²E-4
Answer:
The standard for of the equation would be 2x + 3y = 3
Step-by-step explanation:
To start, we simply need to solve for the constant.
y + 1 = 2/3(x + 3)
y + 1 = 2/3x + 2
2/3x + y + 1 = 2
2/3x + y = 1
Now we need to multiply all the numbers by the largest denominator. This will make all the numbers integers. In this case, that number would be 3.
2x + 3y = 3

Hi there! So, I believe the answer is 60 because 360 degrees in a circle/6 parts is equal too 60. Friend me!!
