There is 16 ounces in a pound, so you would have to divide 40 by 16 getting 2 1/2.
Step-by-step explanation:
CI = p ± z √(pq/n)
For 90% confidence, z = 1.645.
CI = 0.55 ± 1.645√(0.55 × 0.45 / 64)
(x+6)(x+2)=60
expand
x^2+6x+2x+12=60
x^2+8x+12=60
minus 60 both sides
x^2+8x-48=0
factor
what multiplies to -48 and adds to 8
-4 and 12
(x-4)(x+12)=0
set each to zero
x-4=0
x=4
x+12=0
x=-12
x=4 or -12
solutions are x=-12 and 4
Answer:

in the real world -
any trajectory of any item that is thrown on earth can be represented as a quadratic equation.
I do not know what you mean by the mathematical process.
