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

Find the inverse function for y=3/4+x
Sonja [21]

The inverse of this function is y = x - \frac{3}{4}


You can find the inverse of any function by switching the x and y values and then solving for the new y value. Once you've done that, what will be left over is the inverse function.


y = \frac{3}{4} + x ----> Swap x and y

x = \frac{3}{4} + x -----> Subtract 3/4 from both sides.

x - \frac{3}{4} = y ----> rearrange to appropriate order

y = x - \frac{3}{4}


And that is your inverse function.

4x^2 - 12x + 5

= 4(6)^2 - 12(6) + 5

= 144 - 72 + 5

= 77
