The completion of the grouped frequency distribution for the test scores of the fifteen students that took the biology test last week is as follows:
Test scores Frequency
79 to 83 5
84 to 88 2
89 to 93 6
94 to 98 2
<h3>What is a frequency distribution?</h3>
A frequency distribution is a pictorial or graphical representation that shows the number of observations of each categorical value (a group of values) that occurs.
By showing the frequency counts for each category, it becomes easier to determine and interpret the presented information based on their relative frequencies.
Frequency charts, tables, or graphs are used to display frequency distributions of data.

You basically plug in the x values with the given function so the y values are -5,-10,-15,-20
Answer: The value of x is 45
Step-by-step explanation:
The equation x/3-6=9 is a linear equation, where x/3 is the same as one-third of x.
Thus it is easily simplified as such:
x/3-6=9
Collect like terms
x/3 = 9 + 6
x/3 = 15
i.e (1/3) of X = 15
To get the value of x, cross multiply
x = 3 x 15
x = 45
Thus, the value of x is 45
