Step-by-step explanation:
Answer:
x = -31/6 or -5.16
Step-by-step explanation:
3(2x-3) + 49 -2 = 0
Distribute 3 through the parenthesis
3 (2x-3) + 49 - 2 = 0
6x - 9 + 42 - 2 = 0
Calculate the sum or difference
6x - 9 + 42 - 2 = 0
6x + 31 = 0
Move constant to the right side and change its sign
6x + 31 = 0
6x = -31
Divide both sides of the equation by 6
6x = -31
x = -31/6 or -5.16
Answer:
The exact number is $4.461, so you can find the closest amount from the provided options.
Answer:
H₀: μ ≤ μ H₁: μ > μ
Step-by-step explanation:
Hello!
If battery 1 lasts longer than battery 2, and all the batteries of population 1 and population 2 are built using the same method, then you could say that the population mean of the lifespans of batteries 1 are longer than the lifespan of batteries 2. Symbolically: μ₁ > μ₂
This would be your alternative hypothesis.
The null hypothesis is:
H₀: μ₁ ≤ μ₂
Then the correct answer is number 5
Looked for exercise's Options
H₀: μ ≥ μ H₁: μ < μ
H₀: μ ≤ -μ H₁: μ > -μ
H₀: μ ≥ -μ H₁: μ < -μ
H₀: μ = μ H₁: μ ≠ μ
H₀: μ ≤ μ H₁: μ > μ
Q1. p=a-i
Q2. l= 1/2p-w
Q3. t=d/s
I think that these are correct
