9(2x-1)=3(x+2)+3x
18x-9=3x+6+3x
18x-9=6x+6
18x-6x=6+9
12x=15
x=15/12
x=5/4
5x-13=15+7x
-13=15+2x
-28=2x
-14=x
Answer:
13-13x
Step-by-step explanation:
3*2=6
(6-5x+6) + (9-8x-8)
Combine Like Terms
(12-5x) + (1-8x)
Put x on one side and numbers on the other.
(12+1) + (-5x+ (-8x))
13-13x
Answer:
The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance.
The conclusion we can make is that there is 95% of probability that the mean of the population (professor's average salary) is within $99,881 and $171,172.
Step-by-step explanation:
This is a case in which, from a sample os size n=16, a confidence interval is constructed.
The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance. In this case, the probability that the real mean is within the interval is 95%.
Answer:
(-21,-19)
Standard form
Step-by-step explanation:
We are given the equation of circle
General equation of circle:
Centre: (-g,-f)
Radius: 
Compare the equation to find f, g and c from the equation
Centre: (-21,-19)
Radius (r) 
Standard form of circle:
The centre of circle at the point (-21,-19) and its radius is .
The general form of the equation of a circle that has the same radius as the above circle is standard form.
