Answer:
son = 10 , father = 40
Step-by-step explanation:
Let Five years ago the age of son be x years and age of father be 7x years
Present age of son =x+5
Present age of father =7x+5
5 years later their age will (x+10) and (7x+10)
∴7x+10=3(x+10)
7x−3x=20
4x=20
x=5
So, the present age of son=x+5=5+5=10years
and the present age of father=7x+5=35+5=40years
hope it helps you
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:
A polynomial is factored completely when nothing else in the expression can be factored
Example:
x^2+3x-4 completely factored looks like (x+4)(x-1)
Minimum possible number of guests is zero.
C = 60 + 15(0) = $60
Maximum possible number of guests is 100.
C = 60 + 15(100) = $1,560
That looks like Choice (d).
Step-by-step explanation:
By replacing x with 4, we get
- h(4)=1/4×4⁴-3×4³
- h(4)=1/4×256-3×64
- h(4)=64-192
- h(4)=-128
