In this item, we are not given with the figure but knowing that these lines ought to be perpendicular then we will be able to derive the relationship between the slopes of the line.
The slopes of the perpendicular line are the negative reciprocals of one another. If we represent the slopes of the lines as m₁ and m₂, the relationship can be written in the form,
(m₁)(m₂) = -1
We are given with one of the slopes. To determine the value of the second slope then,
m₂ = -1/m₁
m₂ = -1/(2/5)
m₂ = -5/2
<em>ANSWER: m₂ = -5/2</em>
Step-by-step explanation:
First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.
It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.
Answer:
Step-by-step explanation:
True statements
All equallateral triangles are similar. Their sides are all in the same ratio when comparred.
All squares are similar. Same reason as equilateral triangles. All sides to both squares compared are the same.
False Statements
Isosceles triangles can and usually do have different base angles.
rectangles can have all sorts or side lengths. The only requirement is consecutive sides form right angles.
2 rhombuses can have side lengths that are in the same ratio, but the heights are not in the same ratio. That eleminates.
Answer
These are the only true ones: Statements 2 and 5 are true. The rest are not.
