Answer:
x² + y² = 34
Formula:
- (x - h)² + (y - k)² = r² where (h, k) is the center
<u>Here find the radius using distance formula</u>: → origin : (0, 0)
- √(x2-x1)²+(y2-y1)²
- √(3-0)²+(5-0)²
- √9+25
- √34
<u>Thus the equation of circle</u>:
- (x - 0)² + (y - 0)² = (√34)²
- (x - 0)² + (y - 0)² = 34
- x² + y² = 34
Answer:B
Step-by-step explanation:
Given
Every student secure same average score
Standard deviation is denoted by \sigma
Consistency is criteria of acceptance then Student should be selected the standard deviation is least for student B.
Standard deviation tells how a data varies from mean Position .
More Deviation from mean indicates less consistency .
