Step-by-step explanation:
Let's first get the slope of the curve.
[ slope is the derivative of the equation ]
introduce dy/dx :
make dy/dx the subject:
At point (-1, 2):
but a tangent has the same slope as the curve:
m is the slope
c is the y-intercept
At (-1, 2):
equation:
Answer: 55% are girls,45% are boys, number of girls is 122% of the boys,number of boys is 81.8%
Step-by-step explanation: percentage of girls = number of girls ÷ total population × 100
= (198/360)× 100 = 55%
Number of boys = 360 -198 = 162
Percentage of boys = (162/360) × 100 = 45%
Percentage of girls to boys = (198/162) × 100 = 122%
Percentage of boys to girls = (162/198) × 100 = 81.8%
