There are several algebraic properties of equality.
<em>The property that shows that both distance are the equal is the symmetric property of equality</em>
Represent the distance between the elephants and the giraffes with x
Represent the distance between the tigers and the zebras with y
The symmetric property of equality states that:
<em>For 2 expressions or numbers; x and y</em>
<em>If x = y, then y = x</em>
<em />
<em />
<em />
In this context, the above property means that:
<em>If the distance between the elephants and the giraffes is the same as the distance between the tigers and the zebras, then both distance are equal</em>
<em />
Hence, the property to use is the symmetric property of equality

Answer:
2.275%
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours
Plugging the values we have;
z-score = (12,300-11,500)/400 = 800/400 = 2
Now, we want to calculate P(z ≤ 2)
This is so because we are calculating within a particular value
To calculate this, we use the z-score table.
Mathematically;
P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275
To percentage = 2.275%
The smallest value is $0.25 (a quarter) because you can use two quarters and a half dollar. Only one of them can't be a half dollar, but the other two can be.
