-2x-3y <12
For this case what you should do is to graph the following straight line:
-2x-3y = 12
Then, the solution will be the shaded region that satisfies the following inequality:
-2x-3y <12
In the shaded region you will find all the solution points.
Answer:
See attached image
Answer:
1/3
Step-by-step explanation:
A dilation is an enlargement or reduction of an image by a scale factor. The scale factor is the same ratio that cam be found from between the two figures.
The long leg of the original triangle has the length of 6. The small triangle has a long leg of length 2.
The ratio is 2/6 = 1/3.
Answer:
x = 5
Step-by-step explanation:
The length of line segments joining a common point to tangents are always equal.
RS = RQ = 2
PW = PQ = 3
x = PQ + QR = 3 + 2 = 5
Answer:
The minimum sample size is
Step-by-step explanation:
From the question we are told that
The margin of error is
Given that the confidence level is 99% then the level of significance is evaluated as
Next we obtain the critical value of from the normal distribution table
The value is
Now let assume that the sample proportion is
hence
=>
Generally the sample size is mathematically represented as
The quantity increases because people don’t wanna pay more than the equilibrium price
