<h3>What is a Frequency?</h3>
Frequency is the number of times a data point or a set of points within an interval appears often in a data set.
The corresponding frequency to each of the interval given for the data would be as follows:
50 - 54: 2
55 - 59: 6
60 - 64: 7
65 - 69: 3
70 - 74: 2

Answer:
D. Dividing both sides of the equal sign by a negative number.
Step-by-step explanation:
The inequality symbol is reversed when an operation is performed that changes ordering. The most usual cases are multiplication or division by a negative number.
For example:
-2 < 1
2 > -1 . . . . multiply or divide both sides by -1
__
These operations are not the only ones that change ordering. Care must be taken when applying functions. f(x) = 1/x and f(x) = cos(x) are functions that potentially change ordering, for instance.
_____
We note that the question asks about inequalities, and the discussion above is about inequalities. However, the answer choices all refer to an equal sign. (?!) We assume the expected response is ...
D. Dividing both sides of the equal sign by a negative number.
Y=3/1x+3
because slope = 3/1
y intercept = 3
use y=mx+b
Answer:
Slope (m) = infinity
Step-by-step explanation:
Given points:
⇒ (9, 2) and (9, 27)
In order to find the <em>slope</em> of these points, we must use the <em>slope</em> formula.
So the formula is ⇒ y₂ - y₁ / x₂ - x₁
<em>Plug</em> in the<em> given </em>points:
⇒ 27 - 2 / 9 - 9
Solve both the top and bottom (<em>numerator and denominator</em>):
⇒ 25 / 0
Divide:
⇒<em> Undefined. </em>
(<em>Anything</em><em> </em>divided by <em>zero</em> is undefined).
3/4 + 3/4 = (3 + 3)/4 = 6/4 = 3/2
