Answer:
4)X=23
5)x=15
Step-by-step explanation:
8x-77=3x+38
+77 -3x
5x=115
X=23
———
5x+3+9x-33=180
14x-30=180
+30
14x=180
X=15
Answer:
The answer is a: Number of items in several classes.
Step-by-step explanation:
Frequency distributions are tables that represent the number of times a specific data, number object etc appears in a sample. So for example if we have this data
2,2,4,4,6,6,6,8,8,10
The frequency distributions is
Number frequency
2 2
4 2
6 3
8 2
10 1
The other options are identical (c and are the same as percentages can be expressed as fractions. Relative percentages or fractions are tables that express the weight that each category has in the entire data. An example for our data would be: (10 are the total number of obs)
Number Fraction/%
2 2/10 or 20%
4 2/10 or 20%
6 3/10 or 30%
8 2/10 or 20%
10 1/10 or 10%
Answer:
x = 64
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
x + 2x + 114 + x - 10 = 360, that is
4x + 104 = 360 ( subtract 104 from both sides )
4x = 256 ( divide both sides by 4 )
x = 64
