Answer:
<em>Statistical inference</em>
Step-by-step explanation:
The confidence interval is used to give a range of values for a target population while applying the law of probability. Inferential statistics makes use of data obtained from a given population to predict and make a conclusion on a study.
Statistical inference is the process of applying the tools for inferential statistics to analyze data gotten from a given fraction of the population. This process is based on probability and random sampling.
<em>When a confidence interval is used to conclude a population study, it is certainly based on probability. Therefore the correct option is statistical inference. </em>
It would be 48/64 this is done by finding how many times 4 fits in 64 (64/4) then multiplying 3 by that answer
Answer:
The maximum amount of time is 48.2 minutes
Step-by-step explanation:
We can use the equation for a line
y = mx+b
the inital value is 75 gallons ( that is b)
the slope is 2.5 gallons (that is m)
We know that we want to fill it to 195.5 gallons ( that would be y)
195.5 = 2.5x +75
We are going to solve for x (that is the number of minutes)
Subtract 75 from each side
195.5-75 = 2.5x +75-75
120.5 = 2.5x
Divide by 2.5 on each side
120.5/2.5 = 2.5x/2.5
48.2 =x
The maximum amount of time is 48.2 minutes
Given the vector 
.
Now taking the vertices of parallelogram asA 
.
As we know to find the edges of parallelogram ABCD,we proceed as follows
= Position vector of B - Position vector of A
= Position vector of C - Position vector of B
=
= Position vector of D - Position vector of C
= 
= Position vector of A - Position vector of D
=
So, 
are edges of parallelogram.
