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

Answer:
x=5.35
Step-by-step explanation:
2x - 1.7 = 9
2x - 1.7 + 1.7 = 9 + 1.7
2x = 10.7
2x/2 = 10.7/2
x=5.35

Answer:
5cm
Step-by-step explanation:
Given data
Length= 3cm
Width= 4cm
Applying Pythagoras theorem
z^2= x^2+y^2
z^2= 3^2+ 4^2
z^2= 9+16
z^2= 25
square root both sides
z= √25
z= 5cm
Hence the diagonal is 5cm
