Answer:
A, C and D are continuous
Step-by-step explanation:
A is a set of any number x which 30 < x <=45
B is a set that contains only 3 and 7
C is a set of any number x which 60 <= x < 100
D is a set of any number x which -infinity < x < + infinity
E is a set that contains only even whole numbers
A continuous data set is a quantitative data set representing a scale of measurement that can consist of numbers other than whole number, like decimals and fractions.
Answer:
2. Since it is equilateral, we just set up an equation with using any two sides (since they are all equal)
12x - 22 = 10x - 6
12x - 10x - 22 = -6
2x - 22 = -6
2x = 22 - 6
2x = 16
x = 16/2
x = 8
Each side = 74
3. Same formula for this. Get any two sides and setup the equation.
4x - 25 = x + 14
4x - x - 25 = 14
3x = 25 + 14
3x = 39
x = 39/3
x = 13
Each side = 27
4. This one is also simple. Since DE = EF. We substitute its sides with the equations.
8x - 13 = 5x + 17
8x - 5x - 13 = 17
3x - 13 = 17
3x = 17 + 13
3x = 30
x = 30/3
x = 10
DE and EF = 67
DF = 31
