Rewriting the two equations:
[Supply]
[Demand]
Equilibrium price is when
Supply = Demand
⇒ Simplifying the equation by dividing each term by 5
The simplified equation is in quadratic form.
There are three main methods for solving a quadratic equation: factorizing, completing the square, or quadratic formula.
Using the formula, we need the value of a, b, and c which is the constant of the quadratic equation.
, and 
We have a = 1, b = -2, and c = -3716
Substituting these values into the formula we have
Since 'q' represents a quantity, we can't have negative values, so we choose the value of 'q' to be 61.97 ≈ 62 (rounded to the nearest whole number)
Answer: Equilibrium quantity = 62

Answer:
P(X<118.81)=0.0803
Step-by-step explanation:
Assuming the distribution for the mean life is approximately normal, with mean 120 months and variance 64 months^2, we can calculate the parameters for a sampling distribution with sample size = 89 computers.
The sampling distribution mean will be equal to the mean for a single computer:
The standard deviation will be adjusted by the sample size as:
With these parameters, we can calculate the z-score for X=118.81.
Then, the probability that the mean of a sample of 89 computers is less than 118.81 months is:
Answer:
g=64.8 meters
Step-by-step explanation:
=
69.6×24.3= 26.1×g
1,691.28=26.1g
64.8=g
g=64.8
Hope this helps! :)
Oh, I got the order of the ratios wrong, I'm sorry.
I just corrected it.
