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
Answer:
Step-by-step explanation:
2.5*3 = 7.5 She run's 2 1/2 miles, which is equivalent to 2.5 miles, and 3 days per week, so you multiply 2.5 by 3
6.5 *2 = 13 She run's 6.5 miles per day for 2 days, again, because 6 1/2 is equivalent to 6.5 miles. Since she ran for 2 days so you multiply 6.5 by 2
13+7.5 = 20.5 miles
as for the answer, you just add the two numbers you got from Julie running
Answer:
In summary, m = -1/6 and b = 5
Step-by-step explanation:
As we move from A(–6, 6) to B(12, 3), x increases by 18 and y decreases by 3. Thus, the slope of Line AB is m = rise / run = -3 / 18, or m = -1/6.
Let's make use of the slope-intercept formula to find the value of b:
y = mx + b becomes 3 = (-1/6)(12) + b, or
3 = -2 + b
Then b must be 5.
In summary, m = -1/6 and b = 5, and the equation of Line AB is y = (-1/6)x + 5.
