Answer: Convenience sample.
Step-by-step explanation:
Convenience sample is also known as grab or accident or opportunity samples. It is a example of non probability sample that involves selecting of subjects because of the proximity, convenience and accessibility a researcher as to them. This type of samples are not reliable for data gathering when it involves a very large sample space, let's say a global audience.
Answer:
I am not too sure but I think the answer would be 6
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Since P(A)=0.7 and P(A and B)=0.28, then P(B) must be 0.4 because 0.7*0.4=0.28.
Since P(A and B) is a combined probability, P(A) and P(B) are independent.
Answer:
Nina's Garden has an area of 1.3 meters
Step-by-step explanation:
All we have to do is multiply.
4 1/3 * 3/10 = 1.3
So, the answer is 1.3
Hope this helps! :)
This looks like a system of equations:
We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.
c - 3d = 11
+3d +3d
c = 11 +3d
Now we can substitute.
-2(11+3d) + 3d = -16
solve
-22 + -6d + 3d = -16
-22 + -3d = -16
+22 +22
-3d = 6
/-3 /-3
d = -2
So we have found d. We can solve for c.
c - 3(-2) = 11
c + 6 = 11
-6 -6
c = 5
Now we know both D and C. d=-2 and c=5
