Answer:
To allow for easy segregation, analysis, detecting patterns and understanding of the data
Step-by-step explanation:
Classes are, in simple terms, grouping of data based on certain unique characteristics.
Frequencies in classes are the amount of times that said characteristic occurs in an amount of event
The reasons the number of classes is set to between 5 and 20 is to allow for easy segregation, analysis, detecting patterns and understanding of the data
Let x be the length of third side.
12 + x > 13
x > 1-------------(1)
13 + x > 12
x > -1 ------------(2)
by combining (1) and (2)
we have x > -1
Total: 10
P = 4/10
P = 2/5
The probability is 2/5
Answer:
y =2 when x = 150
Step-by-step explanation:
Inverse variation is
xy = k
5*60 = k
300 = k
xy = 300
150y = 300
Divide by 150
150y/150 = 300/150
y = 2
