Answer:
Step-by-step explanation:
27 degrees
Answer:
-10,10
Step-by-step explanation:
The given quadratic equation is
The discriminant of this equation is given by;
where a=k, b=20, c=k
For rational solutions, the discriminant must be zero.
Simplify to get:
This implies that:
Take square root to get:
Answer:
6 hours.
Step-by-step explanation:
A day is 24 hours. So in this case, 3 quarters of a day will be 18 hours, half a day is 12 hours, and a quarter of a day will be 6 hours.
This would not be binomial; the probabilities are not independent, since the balls are drawn without replacement.
The true statement is d, d may cause f.
Explanation:
Strong correlation doesn't always mean causation. For example, there is correlation between time and distance. Time doesn't cause the distance. If time added, the distance is much longer. From the example above, correlation doesn't always mean causation. But for any other example, like, heat has strong correlation with ice melts. The heat is the cause for ice to melt, This correlation might be causation.
