The probability that a randomly selected professor is female and feels "About Right" is 0.40
The distribution table :
____About right _ Oweight _ Uweight __ Total
Female _ 80 _____ 39 ______ 3 _______ 122
Male ___ 52 _____ 10 ______ 16 _______ 88
Total ___ 132 ____ 49 ______ 19 _______ 200
Oweight = Overweight
Uweight = Underweight
Recall :
Probability = required outcome / Total possible outcomes
Probability that a selected professor is female and feels 'About right' :
Required outcome = number of female professors who feels 'About right' = 80
Total number of professors = 200
Hence,
P(Female and 'About right') = 80/200 = 0.40

Convert the angles to degrees. Remember there are 2pi radians in a circle, and a circle has 360 degrees, so conversion factor is 180degrees/pi. Then you can easily approximate the reference angle. Remember you make the reference angle from the positive x-axis and the reference angle will be the angle between the terminal side and the nearest x-axis (either positive side or negative side of the x-axis).

Answer:
n= 0.682539 but if you want it in fraction form its 43/63
Step-by-step explanation:
The equation of y in terms of x is y =(c/b) - (a/b)x
<h3>What is an Equation ?</h3>
An Equation is a mathematical statement formed when two algebraic expressions are equated with an equal sign.
The equation given in the question is
ax + by = c , b ≠ 0.
Express y in terms of x in the equation
by = c - ax
y = (c/b) - (a/b)x
Therefore the equation of y in terms of x is y =(c/b) - (a/b)x
