I believe that it's no,<span> it is not a valid inference because her classmates do not make up a random sample of the students in the school. But I can't be sure, I really haven't done much on inferences, especially in math. I know for sure that her inference is incorrect though. Hope this helps, even a bit!</span>
Answer:
-40a⁴b⁸
Step-by-step explanation:
(8ab⁶)(-5a3b²)
(8ab⁶)(-5a³b²)
=(8×-5)(a×a³)(b⁶×
=-40(a⁴)(b⁸)
=-40a⁴b⁸
The <em>correct answer</em> is:
A) It is an independent event. The outcome of the second spin is unaffected by the outcome of the first spin.
Explanation:
Simple events are events in which one experiment happens at a time and there is only one single outcome. Since we are spinning the spinner twice, this is not a simple event.
Dependent events are events in which the outcome of one affects the other. This is not the case here.
Independent events are events in which the outcome of one event does not affect the probability of the next event. The result of the first spin will not influence the result of the second spin, so these are independent events.
Answer: C. y = 0.75x - 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Slope = -9 - (- 3) / -8 - 0 = -9 + 3/ -8 - 0 = -6/-8 = 0.75
Y-intercept = -3
y = 0.75x + (- 3)
y = 0.75x - 3
Hope that helped!
2. C=500x+100,000 is the answer
