Answer:
inequality form: x<14
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
answer:
6
step-by-step explanation:
- for this you would find the volume and then divide by 1/2
v = l x w x h
v = (1)(2)(3/2)
v = 3
3 ÷ 1/2 = 6
- therefore, it will take 6 half cubes to fill up the container
Answer:
well
Step-by-step explanation:
3 times 15 is 45
then 3 times negative x is -3x
so 45 - 3x = 2x
3 x moved to the other side turns positive
so you have
5x = 45
45÷5
x = 9
Answer:
5 classes.
Step-by-step explanation:
You can use the
rule to determine the number of classes for a frequency distribution.
The
rule says that
where
is the number of classes
is the number of the data points
We know that the number of data points is
= 20.
Next, we start searching for
so that we can get a number 2 to the
that is larger that the number of data points.

This suggests that you should use 5 classes.
