Answer:
The answer is a: Number of items in several classes.
Step-by-step explanation:
Frequency distributions are tables that represent the number of times a specific data, number object etc appears in a sample. So for example if we have this data
2,2,4,4,6,6,6,8,8,10
The frequency distributions is
Number frequency
2 2
4 2
6 3
8 2
10 1
The other options are identical (c and are the same as percentages can be expressed as fractions. Relative percentages or fractions are tables that express the weight that each category has in the entire data. An example for our data would be: (10 are the total number of obs)
Number Fraction/%
2 2/10 or 20%
4 2/10 or 20%
6 3/10 or 30%
8 2/10 or 20%
10 1/10 or 10%
(22 - 3) / (4 +1) = 19/5
slope = 19/5
Two lines are perpendicular when the product between the slopes of the lines is equal to -1, then, if we have the following lines:
they will be perpendicular if,
According to the exercise, the first line is:
the slope for this line is -4.
Write the equation that makes two lines perpendicular,
solve for m2,
Answer:
The slope of the line perpendicular to y=-4x+7 is 1/4.
