FORMULA:
ANSWER:
Plugging the respective value by assuming principle is P,
- 100 = P × 5 × 2/100
- 100 × 100 = 10P
- 10000 = 10P
- 10000/10 = P
- 1000 = P
Hence, Her principle is $1000.

Hope I helped BTW these are 100% correct good luckk:-)
Answer:B. Her mean, median and mode are equal.
Step-by-step explanation:
Mean = (sum of the outcomes)/(total number of outcomes)
Total number of rounds played is 7
The scores for the 7 rounds played are - 6, - 4, - 1 , +3 , - 2, -1, +4
Sum of the scores = - 6 - 4 - 1 + 3 - 2 -1 + 4 = -7
Mean = - 7/7 = - 1
The mode is the most occurring score. Looking at the scores, - 1 occurred twice, so the mode is - 1
The median is the middle score. We would determine it by rearranging the scores in increasing or decreasing order. It becomes
- 6, - 4, - 2, -1, -1, +3, +4
The median is -1
The true statement is
B. Her mean, median and mode are equal.

Answer:
The answer to your question is Center = (-1, 2) Radius = 2
Step-by-step explanation:
Data
x² + y² + 2x - 4y + 1 = 0
Process
1.- Group like terms
(x² + 2x ) + (y² - 4y ) = -1
2.- Complete Perfect square trinomials
(x² + 2x + 1²) + (y² - 4y + 2²) = -1 + 1² + 2²
3.- Simplify
(x + 1)² + (y - 2)² = 4
4.- Get the center and the radius
Standard equation (x - h)² + (y - k)² = r²
Center = (h, k)
Center = (-1, 2)
Radius = 2
