Answer:
2
Step-by-step explanation:
Its the only graph that matches.
Answer:
area is easy because its always the Length times the Width of something so after you get the area you times it by the base which is the bottom part of the cylinder
Step-by-step explanation:
so you would just get the length and the Width and multiply them and... theres your answer!
Answer:
For this case we want to test if life expectancy in country 1 is more than 10 years lower than in country 2, (alternatibe hypothesis), so then the system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
Or equivalently:
Null hypothesis: 
Alternative hypothesis:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem

Alternative hypothesis:
Answer:-12, -10, -3.5, 6, 11
Step-by-step explanation:
You should put 4 as x, -3 as y and a as slope to make an equation :

then you can find the slope and the correct equation of the line :
the slope is :

so the equation of the line will be

D is true
hope this helps
