Answer:
We subtract exponents when diving powers with the same base because they eventually get canceled out when written in expanded form.
Step-by-step explanation:
For example, if we expand the given fractions:
10^3/10^1 = 1000/10 = 100 = 10^2
Now, if we subtract the exponents we get the same result.
10^3-1 = 10^2
So, a^m/a^n = a^m-
n is one of the exponent rules which saves time and makes calculation easier.
Not necessarily, the more correct definition is opposite reciprocal slopes.
The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.
In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.
C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X
