Answer:
No solution.
Step-by-step explanation:
−3> 7x−8 > −0.2
Split this into 2 inequalities:
7x - 8 < -3 Add 8 to both side:
7x < 5
x < 5/7.
and:
7x - 8 > -2 Add 8 to both sides:
7x > 6
x > 6/7.
But x cannot be both less than 5.7 and > 6.7, so No solution.
Hey there!
An outlier in a data set is a number that is WAY larger or WAY smaller than the others in the data set, or does not really fit in the specified "range". In the first one, 452 is way greater than everything else, so it would be the outlier.
In the second data set, 5 would be our outlier because it is much smaller than all the other numbers.
In the last data set, the numbers are pretty close together, but we need to find one that isn't inside the small range. 0.201 appears to be the outlier in this case.
Therefore, here are your answers :)
15: 452
16: 5
17: 0.201
I hope this helps!
Answer:
17.3 cigarettes represent the 35th percentile
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What number of cigarettes would represent the 35th percentile?
This is the value of X when Z has a pvalue of 0.35. So it is X when Z = -0.385.
So
17.3 cigarettes represent the 35th percentile
