Answer:
3
Step-by-step explanation:
A coefficient is a numerical factor that contains a variable.
In this case, 3 is a numerical factor and contains a variable (y).
Hence,
3 is the coefficient of the expression.
Answer:
negative association
Step-by-step explanation:
This diagram is a scatter plot which represents a set of data. Data on a scatter plot can fit one of three descriptions: positive (increasing), negative (decreasing) or no association (points do not form any kind of line). Given this data and the line of best fit, or the line that pass through the majority of the points, it is a decreasing line. Since the line goes downhill, it is a negative association.
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.
If the hypotenuse is 58cm, and one of the others legs is 42cm the answer would be 40cm
Explanation:
Here you have to use the formula
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%2B%20%7Bb%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D)
Then you have to pose the formula in terms of one of the legs, so:
![{a}^{2} = {c}^{2} - {b}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D%20-%20%7Bb%7D%5E%7B2%7D%20)
![a = \sqrt{ {c}^{2} - {b}^{2}}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B%20%7Bc%7D%5E%7B2%7D%20-%20%7Bb%7D%5E%7B2%7D%7D)
So when you change the letter for numbers you have that:
![a = \sqrt{ {58}^{2} - {42}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B%20%7B58%7D%5E%7B2%7D%20-%20%7B42%7D%5E%7B2%7D%20%7D)
a=40
No. Let's say we use 10 and 0.38. 1 X 10 is 10, so if anything is lower than 1, it will be lower than 10. Therefore, 0.38 X 10 is 3.8. This is less than the whole number, 10. Hope this is clear enough.
