You can tell if lines are perpendicular or not by seeing if meet in a right angle. A right angle is like a square, and the lines would have to be 90 degrees.
One example is when the two lines (horizontal and vertical) meet each other at the ends.
(You MUST make sure that they are directly horizontal and vertical. If not, they will either be acute or obtuse).
I hope this helped!
Probabilities are used to determine the chances of events
The probability that a randomly selected person with multiple jobs is a male or married is 0.782
<h3>How to determine the probability</h3>
The given parameters are:
Sample size, n = 655
Male = 381
Married = 299
Male and Married = 168
The number of those that are male or married is calculated as:
Male or Married = Male + Married - Male and Married
So, we have:
Male or Married = 381 + 299 - 168
Evaluate
Male or Married = 512
The probability is then calculated as:
p = 512/655
Evaluate
p = 0.782
Hence, the probability that a randomly selected person with multiple jobs is a male or married is 0.782

Answer:
26.1miles
Step-by-step explanation:
If three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.
If cities A and B are 14 miles apart, then |AB| = 14miles
Also if cities A and C are 22 miles apart, then |AC| = 22miles.
To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.
|BC|² = |AB|² + |AC|²
|BC|² = 14²+22²
|BC|² = 196+484
|BC|² = 680
|BC| = √680
|BC| = 26.1miles
This means that cities B and C are 26.1miles apart
The answer is C. $48 for 6 days is 48(6), then subtract the amount of money Rufus will spend, which is 5(32.5), so it's 48(6)-5(32.5)
Answer:
20% of the money was saved from January.
Here is the way to find percentage.
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
