Answer:
0.00045 
Step-by-step explanation:
450 
⇒
1 = 0.000001
= 450 = 450 × 0.000001 = 0.00045
Answer:
the slope is -1/4 !
Step-by-step explanation:
remember to use x1 x2 y1 and y2 to fnd your answer
Answer:
slope of n =⅔
Step-by-step explanation:
The product of the slope of two perpendicular lines(m1•m2) must equal -1.
This means that if you have the slope of one line,find it's negative reciprocal to obtain the slope of the other.
Thus,-1/(-3/2)=⅔
Answer:
the sample standard deviation
Step-by-step explanation:
The statistic that would enable Dan to estimate the probability that any single class will last somewhere between 47 and 53 minutes is the sample standard deviation. If we have the mean and the standard deviation and we know that the lenghts of the classes form a normal curve, we can compute probabilities either with the empirical rule or using a table of probabilities from a book. The normal distribution is completely determined with the mean and the standard deviation.
The answer would be 296.80.Hope this helps!
