Answer:
<u>radius = √13</u>
Step-by-step explanation:
Forming the equation :
<u>(x - h)² + (y - k)² = r²</u>
- (x, y) = point on circle
- (h, k) = center of circle
- r = radius
Solving :
- (-2 + 4)² + (3 - 6)² = r²
- r² = 4 + 9
- <u>radius = √13</u>
Answer:
Step-by-step explanation:
Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11
left tail p-value = 0.9826
so 98.26% are lower.
The compatible is
190 - 90 =
