Answer:
2.4 i am pretty sure
Step-by-step explanation:
you just have to work backwards
<span>f(x<0)=-f(x>0)=-x^2+5x+12
When x>0, x^2-5x-12=12, x=8, y=12
Therefore, f(x)=12 goes through point (8,12).</span>
Answer:
1. The population of interest is all city goverments in the U.S.
5. The parameter of interest is the proportion of the city goverments in the U.S. that provide electricity to their residents.
Step-by-step explanation:
Hello!
Missing questions:
Which of the following is true? Select all that apply.
- The population of interest is all city governments in the U.S.
- The population of interest is the 192 cities.
- The population of interest is all city governments that provide utilities to their residents.
- The population of interest is 6.25%
- The parameter of interest is the proportion of the city governments in the U.S. that provide electricity to their residents.
- The parameter of interest is 6.25%
- The population of interest is the 20 counties.
- The parameter of interest is the list of all counties in the U.S.
The objective of this essay is to test utilities provided by city governments, for this a sample of 20 counties was taken then contacted each city of them counting how many of them provided utilities to their residents, finding out that 12 out of 192 cities (6.25%) provided electricity to their residents.
The study variable is:
X: Number of city governments that provide utilities (electricity) to their residents, in a sample of 192.
The population of the study is the city governments in the U.S.
And the parameter of interest is the population proportion of city governments in the U.S. that provide electricity to their residents.
I hope it helps!
Well the difference is -43 so I'm pretty sure it's gonna be A
The angle adjacent to angle 6 is the one we need to find first. To do this, add the measures of the intercepted arcs and divide by 2. 60 + 50 = 110, and half of that is 55. That means that both adjacent angles to the angle 6 are 55 (vertical angles are congruent). The measure of all the angles added together is 360 and angle 6 is vertical to the other "sideways" angle, so they are congruent as well. 360 - 55 - 55 = 250. Split that up between angle 6 and its vertical angle to get that each of those measure 125. Angle 6 measures 125, choice b from above.
