Group of students = 18/18 (100%)
Boys = 9/18 (50%)
Boys with brown eyes = 4/18 (idk :p)
It's 4/18 because:
Brown eyed boys make out the 4/9 of the boys, and boys make out the half of the whole class. So the easiest way was to double 9 and get x/18. (Sorry for my bad English..)
Turn the percent into a decimal . Ex: 80% = .80 as a decimal. Then divide.
Now find equation of the graph. It passes through the point (2,3), and intersects y-axis at -2.
Answer:
y = -2
Step-by-step explanation:
To find the equation of the tangent we apply implicit differentiation, and then we take apart dy/dx
The equation is
implicit differentiation give us
But we know that
Hence, for the point (0,-2) and by replacing for dy/dx
Hence m=0, that is, the tangent line to the point is a horizontal line that cross the y axis for y=-2. The equation is:
y=(0)x+b = -2
