Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
The answer to your problem is
x=5/2
y=5
x=-4
y=2
8xy-7xy-3xy-3y²-2y²+8y²+5x²+12x²
then simplify by combining like terms -2xy+3y²+17x²
Answer:
Option C is correct
Volume of coffee in the thermos is, 150.8 cubic inches
Step-by-step explanation:
Volume of the cylinder is given by:
Where
V is the volume of the cylinder
r is the radius
h is the height of the cylinder respectively
As per the statement:
A thermos in the shape of a cylinder is filled with coffee.
the height of the cylinder is 12 inches and its radius is 2 inches
⇒ h = 12 inches and r = 2 inches.
Substitute the given values and use 
in [1]
then;
Simplify:
V ≈150.8 inches.
Therefore, the volume of coffee in the thermos is, 150.8 cubic inches
First, we need to know the amount of the total chocolates, which is :
13 + 16 + 11 = 40
White Milk
The probability that she randomly picks either white chocolate or milk is
= (16 + 11)/40
= 27/40
Hope this helps
