Answer:
Step-by-step explanation:
there are function that "invert" each other..
subtraction inverts addition...
3+2 = 5 ... 5-2 = 3
division inverts multiplication
5*2 = 10 ... 10/2 = 5
Using that concept, "factoring" is basically the inverse of multiplication
3x^2 + 9x can be factored to 3x(x+3)
if you multiply that out it reverts back to the original equation
so x^2 + 5x + 6 factors to (x+3)(x+2)
if you multiply that out (foil it)
you get x^2 + 5x + 6
Hi there!
Okay, so we are solving for s. This is pretty simple. Just follow the steps below!
-10s = -8 - 9s
Step 1) Simplify both sides of the equation.
-10s = -8 + - 9s
-10s = -9s - 8
Step 2) Add 9s to both sides.
-10s + 9s = -9s - 8 + 9s
-s = -8
Step 3) Divide both sides by -1.
-s/-1 = -8/-1
s = 8
Our final answer is s = 8.
Hope this helps!
Answer:
The lower limit of 95% confidence interval is 99002.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $100,000
Sample mean,
= $111,000
Sample size, n = 36
Alpha, α = 0.05
Population standard deviation, σ = $36,730
First, we design the null and the alternate hypothesis

We have to find the lower limit of the 95% confidence interval.
95% Confidence interval:

Putting the values, we get,


The lower limit of 95% confidence interval is 99002.
