Answer:
1/3
Step-by-step explanation:
(1/3)^2x(1/3)^-1
so, we can write this as:
1/3 x 1/3 x 3/1
if calculated by cutting, the answer is 1/3
There is also an easier way to do this,
(1/3)^2 x (1/3)^-1
as the bases are same, the powers will be added.
2+(-1)
2-1
=1
so,
(1/3)^1 or 1/3
Answer:
Histogram.
Step-by-step explanation:
Such a Graph is called Histogram.
A histogram can be defined as a visual representation of data in form of bars of different heights. In histogram, each and every bar groups numbers into ranges. The greater the height of the bar, the larger the data falls into its range. It basically represents shape and spread of continuous data sample.
s= 18
and,
t= 48
These values makes it correct.
Answer: His class has approximately 150 textbooks in total
Explanation: Because it is given that each student carries about 5 textbooks, with 30 students in the class, the equation would be 5 • 30 = 150. Some students may have more, while others may have less, so the average is given as 5 in order to simplify the equation.
