Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)
Answer:
y-intercept: (0,6)
slope = -2
equation: y = -2x + 6
Step-by-step explanation:
1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.
2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula 
and solve:
So, the slope is -2.
3) With the found information, use the slope-intercept formula 
to write the line's equation. Substitute values for the 
and 
.
represents the slope, so substitute -2 in its place. represents the y-intercept, so substitute 6 in its place. This gives the following equation:
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.
Answer:
465
Step-by-step explanation:
Let's move the terms with n to one side:
12n < 3n + 28 => 12n - 3n < 28
9n < 28 => n < 28/9
n < 3.1111
The only answer which satisfies this inequality is A.
