Answer:
x=62
Step-by-step explanation:
The sum of x ,28, and 90 is 180 since it forms a straight line
x+28+90 = 180
Combine like terms
x+118 =180
Subtract 118 from each side
x+118-118 =180-118
x= 62
Answer:
x
Step-by-step explanation:

A relative frequency histogram is the data display that Helena should use if she wants to know the percentage of the teams that scored higher than her team.
<h3>What is a relative frequency histogram?</h3>
A relative frequency histogram is a frequency histogram that compares each class to the total number of items.
Since she wants a data display, a histogram is required to show the graphs of the scores of the various teams.
However, she needs to combine the histogram with relative frequencies to show the ratio of the frequency of her team's score to the total frequency.
Thus, Helena requires a relative frequency histogram to achieve the data display of percentages of the teams' scores.
