Problem 3 The cockpits for certain fighter jets were designed for men between 5'8" and 6'3" tall. In 2007, the U. S. Centers for
Disease Control determined that the average height of a woman in the United States is 63.8 inches with a standard
deviation of 3.8 inches.
What percentage of women are within the optimal height range for fitting in the cockpit of the fighter jet? State your
assumptions and show support work and or pictures of your work from Desmos.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
