the only statement that is true is the one in option D.
"Bar graphs are used to represent data that is discrete".
<h3>Which of the statements are true regarding dot plots, bar graphs, and histograms?</h3>
Dot plots, bar graphs, and histograms are used to repersent graphically data sets.
Thus, what these graphs do represent are populations in a data set with a given property.
Remember that data is usually discrete, so we usually use dot plots and bar graphs to represent discrete data.
Histograms show distributions of numerical data (it can be used for continuous or discrete data).
With all that in mind, we conclude that the only statement that is true is the one in option D.
"Bar graphs are used to represent data that is discrete".

Answer:
perimeter = 28.13 cm
Step-by-step explanation:
Calculate the length of a line drawn from A to C.
sin 85 = b/8, b = 7.97
cos 85 = c/8, c = 0.697
AC² =7.97² + (6 + 0.697)² = 63.52 + 44.85 = 108.37
AC = 10.41
Now you have a right triangle ADC with a known hypotenuse and one leg.
Using the Pythagorean theorem:
DC² = 10.41² - 5²
DC² = 108.37 - 25 = 83.37
DC = 9.13 cm
perimeter = 5 + 6 + 8 + 9.13 = 28.13 cm
Increase.
1/4 can be translated to 25%
1/2 can be translated to 50%
25% to 50% is an increase.
Answer: x = 8, y = 2, coordinates (8,2)
Step-by-step explanation:
2x = 4y + 8 (divide by 2 to get value of x)
x = 2y + 4
(now substitute x into the second equation to find value of y)
2y + 4 - 2y = 4
2y - 2y = 4 - 4 (divide by 2 to get value of y)
y - y = 2 - 2
y = 2
Now plug in value of "y" to get value of "x".
x - 2(2) = 4
x - 4 = 4
x = 8
Coordinates (8,2)
