Answer with explanation:
It is given that, there is positive correlation between drinking coconut milk and eating potato chips.
→Correlation coefficient is denoted by r.
→The value of r lies between , -1 and 1 which is represented as , -1 ≤r≤1.
→Correlation that is relation between two variables is said to be strongly positive, if r is equal to 1, and it is said to be strongly weak, if it is equal to -1 , and said to have no association if r=0.
→ The meaning of positive correlation is that value of r, is greater than >0.8 but less than 1.
The two variables which are positively correlated ,can have following relationship.
1. With increase in one other increases.
2.With decrease in one other decreases.
3. Slope will be a linear that is a straight line not passing through origin.
The equation of the hyperbola is : ![\frac{x^{2}}{48^2} - \frac{y^{2}}{14^2} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E%7B2%7D%7D%7B48%5E2%7D%20%20-%20%5Cfrac%7By%5E%7B2%7D%7D%7B14%5E2%7D%20%20%3D%201%20)
The center of a hyperbola is located at the origin that means at (0, 0) and one of the focus is at (-50, 0)
As both center and the focus are lying on the x-axis, so the hyperbola is a horizontal hyperbola and the standard equation of horizontal hyperbola when center is at origin:
The distance from center to focus is 'c' and here focus is at (-50,0)
So, c= 50
Now if the distance from center to the directrix line is 'd', then
![d= \frac{a^{2}}{c}](https://tex.z-dn.net/?f=%20d%3D%20%5Cfrac%7Ba%5E%7B2%7D%7D%7Bc%7D%20%20%20)
Here the directrix line is given as : x= 2304/50
Thus, ![\frac{a^{2}}{c} = \frac{2304}{50}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%5E%7B2%7D%7D%7Bc%7D%20%20%3D%20%5Cfrac%7B2304%7D%7B50%7D%20%20)
⇒ ![\frac{a^{2}}{50} = \frac{2304}{50}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%5E%7B2%7D%7D%7B50%7D%20%20%3D%20%5Cfrac%7B2304%7D%7B50%7D%20%20)
⇒ a² = 2304
⇒ a = √2304 = 48
For hyperbola, b² = c² - a²
⇒ b² = 50² - 48² (By plugging c=50 and a = 48)
⇒ b² = 2500 - 2304
⇒ b² = 196
⇒ b = √196 = 14
So, the equation of the hyperbola is : ![\frac{x^{2}}{48^2} - \frac{y^{2}}{14^2} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E%7B2%7D%7D%7B48%5E2%7D%20%20-%20%5Cfrac%7By%5E%7B2%7D%7D%7B14%5E2%7D%20%20%3D%201%20)

Answer:
4
Step-by-step explanation:
The three angles in a triangle measure 180°. So add the the 2 known angles 70° + 63° = 133. Then subtract it from 180° to get the unknown angle 180 - 133 = 47.
Now that we know the third angle is 47 we find which number that when multiplied by 11 and 3 is added to that number you get 47.
11×4+3 = 47
Therefore l, the answer is 4
