The rules of this problem will be as follow:
we have a * b = x
1) If a > 1 and b > 1 ⇒⇒⇒ x > a and x > b
2) If a > 1 and b < 1 ⇒⇒⇒ x < a and x > b
3) If a < 1 and b < 1 ⇒⇒⇒ x < a and x < b
4) If a = 1 and b > 1 ⇒⇒⇒ x > a and x = b
5) If a = 1 and b < 1 ⇒⇒⇒ x < a and x = b
=================================================
2a) (13/4) * (5/8) = x ⇒⇒⇒⇒ rule (2)
∴ x < (13/4) and x > (5/8)
2b) (4/3) * 6 = x ⇒⇒⇒ rule (1)
∴ x > (4/3) and x > 6
2c) (2/5) * (1/7) = x ⇒⇒⇒⇒ rule (3)
∴ x < (2/5) and x < (1/7)
2d) (5/8) * (7/7) = x ⇒⇒⇒ rule (5)
x = (5/8) and x < (7/7)

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
0.17 because you would do $2.04/12=0.17 so that would be the answer want to check it do 0.17*12=2.04 so 0.17 is your answer
Answer:
24 blocks
Step-by-step explanation:
- b = 2(9) + 6
- b = 18 + 6
- b = 24
