Answer:
a is false
Step-by-step explanation:
a) the interquartile range is not 52
the interquartile range is the 75 percentile subtracted by the 25 percentile
Hence the interquartile range = 49-30

It should be noted that the rotation symmetry that an equilateral triangle has is 3.
<h3>What is rotational
symmetry?</h3>
It should be noted that rotational symmetry simply means when an object is rotated on its own axis.
In this case, it should be noted that the rotation symmetry that an equilateral triangle has is 3.
Also, the number of degrees that you can rotate the shape to carry it onto itself will be 60°, 120°, and 180°.

Answer:
551/10 0.551
Step-by-step explanation:
Answer:
D. 24
Step-by-step explanation:
Angles are the same, so 84 = 3x.
To get x alone, you divide 3 by both sides.
84/3 = 24
24 = x.
Answer:
1.40 litres; order of operations
Step-by-step explanation:
Part A:
First, write it out in the full form.
#1 (.75 litres of blackberry juice + .60 litres of blueberry juice + .25 litres of guava juice) - .20 litres drank = 1.4 litres of juice remaining in the jar
Part B:
Removing the wordy descriptions from the expression, we get the following:
#2 (.75 + .60 +.25) - .20
or, by adding the numbers in the parentheses first:
#3 (1.60) - .20 = 1.40
#4 1.40 litres of juice left in the jar
The order of operations was used in moving from step #2 to step #3, as operations within the parentheses were conducted before subtracting the .20 litres of juice which were drank.
