100,000 is basically the same thing as 100k
Answer:
y= -8/11 x=-63/11
Step-by-step explanation:
Rewrite equation
Step: Solve6x+y=−10for y
Step: Substitute−6x−10 for y in 4x−3y=14
Step: Substitute −8
/11 for x in y=−6x−10
y= −62
/11 --- (Simplify both sides of the equation)
___________________________________________
y= -8/11
x=-63/11
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:
C. 200 minutes, $260
Step-by-step explanation:
The equations would look like this
Lynn = y = 1.10x + 40
Heather = y = 1.15x + 30
Now just plug in.
Lynn
260 = 1.10(200) + 40
260 = 220 + 40
260 = 260
Heather
260 = 1.15(200) + 30
260 = 230 + 30
260 = 260
Hope this helps ya! Keep smiling!
