Answer:
the answer is in the explanation
Step-by-step explanation:
For example, two pivot system
1 0 2 X
0 1 3 Y = 0
0 0 0 Z
X + 2z = 0
x = -2z
y + 3z = 0
y = -3z
free variables
z = z
x -2
y = -3
z = 1
(x, y, z) = (-2, -3, 1)
so the option D is correct
since A has 2 pivots
there is 1 free variable
so ax = 0
so say the number he's thinking of is n, write n down, then he multiplies it by 5 which is 5n then he subtracts 60 from 5n, which is 5n-60, the question states that the answer "5n-60" is equal to the number he started with which is n, so you setup 5n-60=n and solve for n.
Options :
A.
33.5%
B.
20,000 and 33.5%
C.
500 and 20,000
D.

Answer:
A.) 33.5%
Step-by-step explanation:
A statistic value is simply a numerical statistical estimate or value which is obtained from the sample data or value.

Proportion of supermarket customers who do not buy store-brand products.
20,000 = population size ;
500 = sample. Size
33.5% =. Statistic
