Please help... I'm stuck on number 44 and I can't remember how to do it
2 answers:
Ok so basically, you are going to use the distributive property to solve this problem.
First, Use the distributive property.
So basically 3(x + 4) = 9 would be:
3x + 12 = 9 after the distributive property
Then you subtract 12 from both sides
3x = -3
Then you divide 3 by both sides
you will get x = -1
Hope this helps

Answer:
Option D) is true about median
Step-by-step explanation:
We are given the following information in the question:
Median:
- The median is the middle number or the center of the data when the data is sorted in either ascending or descending order.
- The median is not affected by the presence of any outliers since the data is sorted.
Option A) Medians are not affected by the outliers
Option B) Medians can only be calculated when the data is sorted.
Option C) This is a false statement about the medians.
Option D) True
When there are even number of observations, the median is the mean of the two middle numbers.
Answer:
The equilibrium point is (3, 3620)
Step-by-step explanation:
We set the supply and the demand equation equal to each other and solve:
We can solve by factoring:
Setting each factor equal to zero we get:
Only a positive quantity makes sense, so q=3 is the equilibrium quantity.
To get the equilibrium price we just plug 3 in place of q in any of the functions. Let us use the demand function which is easier to handle:
Therefore the equilibrium price is p=3620
In ordered pair form the equilibrium point is (3, 3620)
