Answer:
?
Step-by-step explanation:
Corresponding measures have the same ratio.
.. (x -1)/4 = (2x +1)/10
.. 5(x -1) = 2(2x +1) . . . . . . multiply by 20
.. 5x -5 = 4x +2 . . . . . . . . eliminate parentheses
.. x = 7 . . . . . . . . . . . . . . . add 5 -4x
x = 7
Answer:
A) amount of snowfall in a blizzard
Step-by-step explanation:
Both continuous and discrete data are quantitative.
The difference is that
- Continuous data can take any value. You obtain it by measurement.
- Discrete data can take only certain values. You obtain it by counting.
The amount of snowfall in a blizzard is continuous data. It can take any value such as 100.3 cm or 250.5 cm

B) is wrong. The number of students who pass a math quiz is discrete data. You can't have half a student.
C is wrong. The number of languages an individual speaks is discrete data. You can't speak half a language.
D) is wrong. The number or treadmills in a gym is discrete data. You can't have half a treadmill.
