Answer:
A scatter plot to the right shows a very strong association.
Step-by-step explanation:
Because a scatter plot to the right shows that both variables are positive and they both increase, so it shows a strong association between those variables.
Answer: 187.7 mph
Step-by-step explanation:
v = 125 mph
t = 1.2 min
v2 = ?
t2 = 0.8 min
We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.
![\frac{125mph}{x} =\frac{1.2min}{0.8min}](https://tex.z-dn.net/?f=%5Cfrac%7B125mph%7D%7Bx%7D%20%3D%5Cfrac%7B1.2min%7D%7B0.8min%7D)
![x = \frac{(125)(1.2)}{0.8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B%28125%29%281.2%29%7D%7B0.8%7D)
![x=187.5mph](https://tex.z-dn.net/?f=x%3D187.5mph)
Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)
Answer:
7. 6x³ - 12x² + 12x + 15
Step-by-step explanation:
(3x-6)(2x² - 4x - 5)
3x • 2x² = 6x³
3x • -4x = -12x²
3x • -5 = -15
-6 • 2x² = -12x²
-6 • -4x = 24x
-6 • -5 = 30
combine terms
6x³ - 12x² - 15 - 12x² + 24x + 30
combine like terms
6x³ - 24x² + 24x + 15
hope this helps :)
