Answer:
The purpose of statistical inference is to provide information about the population based upon information contained in the sample.
Step-by-step explanation:
population based upon information contained in the sample
Step-by-step explanation:
Statistical inference is the process of using data analytics to deduce proprierties of an underlying probability distribution.
For example, if I want to know the percentage of Buffalo Bills fans that are from Canada. There is no way I can ask this question to every Bills fan(every Bills fan is the population). What I can do, for example, is go to a game and ask some of the fans there, that is, of a sample.
14.99 x 12 = 179.88
179.88 x 2 = 359.76.
She would spend 359.76 in 2 years
X - 3y - 3z = 9
5x - 3y + 3z = -3
--------------------add
6x - 6y = 6
x - 3y - 3z = 9.....multiply by -4
-4x + 2y - 4z = 4..multiply by 3
-------------------
-4x + 12y + 12z = -36 (result of multiplying by -4)
-12x + 6y - 12z = 12 (result of multiplying by 3)
-----------------add
-16x + 18y = - 24
6x - 6y = 6.....multiply by 3
-16x + 18y = -24
---------------------
18x - 18y = 18 (result of multiplying by 3)
-16x + 18y = -24
--------------------add
2x = - 6
x = -6/2
x = -3
6x - 6y = 6
6(-3) - 6y = 6
-18 - 6y = 6
-6y = 6 + 18
-6y = 24
y = -24/6
y = -4
x - 3y - 3z = 9
-3 - 3(-4) - 3z = 9
-3 + 12 - 3z = 9
9 - 3z = 9
-3z = 9 - 9
-3z = 0
z = 0
so ur solution is (-3,-4,0)
Oooooooonnnnnneeeeeeeemmmmmmmmiiiiilllllllliiiiieeee
Answer:
$144
Step-by-step explanation:
Use the simple interest formula, I = prt, where I is the interest money created, p is the starting amount, r is the interest rate as a decimal, and t is the amount of time.
Plug in the original amount, interest amount, and amount of time:
I = prt
I = 450(0.08)(4)
I = 144
So, $144 in simple interest is made in 4 years
