The firs term
A(1)=-6+(1-1)(6)
A(1)=-6+(0)(6)
A(1)=-6
The fourh term
A(n)=-6+(n-1)(6)
A(4)=-6+(4-1)(6)
A(4)=-6+(3)(6)
A(4)=-6+18
A(4)=12
The tenth term
A(10)=-6+(10-1)(6)
A(10)=-6+(9)(6)
A(10)=-6+54
A(10)=48
Answer:
D. -6,12,48
Almost all correct except two. Please check corrected image.
25 and -12 because when you subtract 12 from 25 you will get 13 and when you multiply 25 by -12 you will get -300
I don't know all 12, but I can tell you some.
1. Shade the side of the line that satisfies the inequality.
2. If the inequality sign has an "or equal to" line under it, make the line on the graph connected.
3. If the inequality sign does not have an "or equal to" line under it, make the line on the graph dashed.
4. Isolate y (or the variable that is being used), and keep it on the left side of the inequality.
Answer:
C
Step-by-step explanation:
When to use regression test?
- This is done to find the relationship between 2 variables. One dependent and one independent.
When to use Multiple regression test?
- Extension of regression test. It is used to predict value of 1 variable when it depends on 2-3 other variables. Multivariable, basically.
When to use 1-sided t-test?
- We check for possibility of relationship of something from one side. 1 side effect. With a hypothesis and its alternate.
When to use 2-sided t-test?
- This is same as 1-tailed but it looks for possibility from 2sides. A hypothesis and alternate, whether less or more.
Now, Options A and B are not right since we aren't comparing 2 variables here. People believe second born subjects are more intelligent. We have to perform a test to see whether this is true or not. One sided answer. So, we will use One-sided t-test.
