Answer:
c. observational study
Step-by-step explanation:
<em>Researchers compare the rates of autism for children who did and did not receive the standard measles-mumps-rubella vaccine, to see if the vaccine might be responsible for autism in some children.</em>
This study design in the above scenario is observational study because the researcher are obviously observing whether the vaccine is affecting the children. Note that Observational study is like experiment which attempts to understand the cause and effect relationships on a subject.
point slope form
y-y1 = m(x-x1)
y-6 = 2(x-2)
from the answers shown, should the slope be 5?
then the answer would be
y-6 = 5(x-2)
Choice A

Answer:
C. 4
Step-by-step explanation:
Since this one is already graphed and we can see it clearely we can just count, but you can also do change in y over change in x (aka "rise over run") to find the slope.
So, we count and find it is four up and one over. 4/1 = 4 = c
Hope this helps, have a nice day! :)
Answer:
z = 60
Step-by-step explanation:
z/3 = 20. (Multiply both sides by 3 to isolate ‘z’)
20 • 3 = 60
