The total number of students is 250 from the solution in the image.
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
radius = √98
center = (5.9,6.7)
equation of the circle = ?
Step 02:
Equation of the circle
(x - a) ² + (y - b) ² = r ²
(a , b) = center
(x - 5.9) ² + (y - 6.7) ² = (√98) ²
(x - 5.9) ² + (y - 6.7) ² = 98
The answer is:
(x - 5.9) ² + (y - 6.7) ² = 98
.20 is the correct answer because 100-99.80
80% of 35 is 28 :) hope this helps!
C, because the independent variable would be the variable that is changing -- in this case, the temperature. The dependent variable changes according to the independent variable, and is called so because it depends on the temperature of the pool.
