3v-9v is -6v
-6v=30 Divide each side by -6
v=-5
To check: substitute -5 back into the equation wherever you see v
3(-5)-9(-5)=30
-15+45=30
30=30
Answer: C. a parameter.
Step-by-step explanation:
- In statistics, a parameter is a measure ( such as population mean , population proportion... ) generated from the entire population .
- A statistics is also a measure( such as sample mean , sample standard deviation , sample proportion,..) but generated from the sample taken from population.
Given : The Department of Motor Vehicles reports that 32% of all vehicles registered in a state are made by a Japanese or a European automaker.
Here, Department as considered the entire population of vehicles registered in a state are made by a Japanese or a European automaker to find the proportion.
Thus , 32% = Population proportion of vehicles registered in a state are made by a Japanese or a European automaker
So , The number 32% is best described as <u>a parameter</u>.
Hence, the correct answer is C. a parameter.
Answer: -0.5
Step-by-step explanation:
We can see that at x=0 that Y=2, when x=2, y=1, so we do the x1 - x2 = -2 and y1-y2 = 1
Then we do 1 / -2 = -0.5
The average rate of change is -0.5
Answer:
false
Step-by-step explanation:
If the inequality symbol, is an x or equal to symbol, the dot will be closed.
Pick the number and put it at the center and then label the rest on the number line.
If the variable is on the left side of the inequality, you can use whichever way the "arrow" (the inequality symbol) is pointing to shade.
If it is w ≥ 0, then you would graph on the number line 0 and make the dot filled in, and graph in the direction going right (>)
