Answer:
A. None
General Formulas and Concepts:
<u>Algebra I</u>
- Perpendicular Lines/Intersecting Lines have 1 solution.
- 2 identical Lines have infinitely many solutions.
- Parallel Lines have no solution.
Step-by-step explanation:
According to the graph, we see that we have 2 parallel lines. Therefore, there will be no solution.
Answer:
b=5m+r/m
Step-by-step explanation:
Let's solve for b.
r=(b−5)(m)
Step 1: Flip the equation.
bm−5m=r
Step 2: Add 5m to both sides.
bm−5m+5m=r+5m
bm=5m+r
Step 3: Divide both sides by m.
bm/m=5m+r/m
b=5m+r/m
Answer:
b=5m+r/m
I don't know if i'm right or what because I haven't learned binomial in like almost 4 years. (3x+y)?
Answer:
Step-by-step explanation:
The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are
a. A reduction in the bias of the estimate.
b. A reduction in the variability of the estimate.
The width of confidence interval is determined by the margin of error
Margin of error = z × s/√n
A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.
