Hello!
The residual for the point (5,1) is
To calculate residuals, we need to calculate the value of the line of best fit in the same x coordinate as the point we want to study to know the Predicted-y-value. To do so, we make the substitution of 5 into the equation:

Now we determine the residual with the following equation:

Have a nice day!
Answer:
i think circumference. good luck :D
Step-by-step explanation:
Step-by-step explanation:
2(5+7)-1=(5+2)+(5+3)
10+14-1=7+8
23=15
23-15=0
8
Wouldn’t be a,or d. I would honestly say B..
To calculate the remaining number of teams, use the sequence formula:
a(n) = a(1)Rⁿ-¹
Where a(n) and a(1) are the nth and first terms. R is the factor. Therefore, 24 teams is valid value.
After 5 rounds :
a(5) = 128*(½)⁴
a(5) = 128/16 = 8
8 teams are remained.
