Answer:
Dot plot, because a small number of scores are reported individually.
Step-by-step explanation:
Histogram is usually used when a group of data to be represented is usually large and given in ranges or intervals.
However, for a data set, such as the scores of the group of 12 students who participated in a dance competition are reported individually, and not as ranges or intervals, a dot plot would best for representing this small number of scores.
See attachment below to see how we can easily represent the given scores of the students on a dot plot. Each dot represents a score value for each student.
Step-by-step explanation:
I think it's 48 square units
Answer: x = 12 ft
Step-by-step explanation:
let the erect part of the pole be x
the slanted part of the pole will be 25-x
the ground distance = 5
they form a right triangle
apply Pythagoras theorem
5^2+x^2=(25-x)^2
25+x^2=x^2 - 50x + 625
50x=625-25
50x=600
x=600/50
x=12 feet
Answer:
(0, 7.5)
Step-by-step explanation:
Compare the equation to the standard-form equation of a circle:
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . center at (h, k); radius r
You will notice that ...
h = 0
k = 7.5
The center is (h, k) = (0, 7.5).
