A. -3/7 because parallel lines always have the same slope
Answer:
Correlation is a measure of linear relationship.
Step-by-step explanation:
We are given that a correlation of 0.793 was found between the items answered and the mean score in a test.
- Correlation helps us to to know how to variables are related to each other.
- It is a statistical technique that help us to know type of relation between two variable. It may be a direct relation or a inverse relation.
- In other word, correlation is basically a measure of linear relationship between two variables.
- The correlation ranges from -1 to 1. A correlation between 0.7 and 1 is considered to be a strong correlation.
- A correlation of 0.793 means that there is a strong linear relationship between the two variables.
- Yes, there is a linear relationship between the number of questions answered and the mean score of test.
- So, it can be said as the number of questions answered increases, the mean score increases as well.
Answer:
The third choice: g(x) = (x + 3)²
Step-by-step explanation:
When translating left, you add the units shifted to x, so instead of x, we have (x + 3)
There both not in the middle and the first one is after the decimal and the second one is before and also they are both next to the decimal
