Answer:
The point
is not a solution of the system of inequalities
Step-by-step explanation:
we have
-----> inequality A
-----> inequality B
we know that
If a ordered pair is a solution of the system of inequalities
then
the ordered pair must be satisfy the inequalities of the system
Verify
For ![x=0, y=0](https://tex.z-dn.net/?f=x%3D0%2C%20y%3D0)
substitute the value of x and the value of y in the inequalkity A and in the inequality B
Inequality A
![0\leq 0^{2} -4](https://tex.z-dn.net/?f=0%5Cleq%200%5E%7B2%7D%20-4)
-------> is not true
therefore
The point
is not a solution of the system of inequalities
The minimum percentage of recently sold homes with prices between $197,650 and $242,350 is 88.9%.
<h3>What is Mean ?</h3>
Mean is the ratio of the sum of all the data points to the number of data points.
It is given that
mean of $220,000 with a standard deviation of $7450.
The range is given , let the range is represented by x - --y
It is given that x = 197650 and y = 242350
Let the number of homes sold is k
To determine the value of k
upper level = (y-mean)/standard deviation = (242350-220000)/7450 = 3
lower level = (mean-x)/standard deviation = (220000-197650)/7450 = 3
probability = 1-(1/k²)
k= 3
= 1 - (1/3^2)
= 1 - 1/9
= 0.889 or 88.9%
So, the minimum percentage of recently sold homes with prices between $197,650 and $242,350 is 88.9%.

1,2,4,5,10,20 are all factors of 20. (To be extra sure you can ask google too).
Answer:
To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.
