Answer:
corresponding angles
Step-by-step explanation:
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.

Answer:
Proportionality constant = 
Step-by-step explanation:
From the graph attached,
Data set representing the relation between seeing lightning and the hearing thunder is,
{(15, 3), (25, 5), (35, 7), (45, 9)}
Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)
d = kt
Here k = proportionality constant
k = 
From the data set one point is (15, 3).
k = 
k = miles per second
Therefore, proportionality constant is miles per second.
Answer:
- <u>Option</u><u> </u><u><em>A</em></u><em>. If percentages are used, the sum should be a 100%. If proportions are used, the sum should be 1.</em>
Explanation:
The <em>relative frequency</em> can be measured as a ratio (proportion) or as a percentage.
As a ratio, the relative frequency is the number of times that the desired outcome is observed (either theoretically or experimentally) divided by the total number of possible outcomes (theoretically) or observed (experimentally).
As a<em> percentage</em>, the relative frequency is the ratio multiplied by 100.
This shows it mathematically:
- relative frequency of event 1 = frequency of event 1 / number of events
- relative frequency of event 2 = frequency of event 2/number of events
- relative frequency of event n = freqquency of event n/number of events
- Total relative frequency = sum of of relative frequencies
= sum of all (n) frequencies / number of events =
= number of events / number of events = 1
As a percentage, total relative frequency = 1 × 100 = 100
