Which students, if any, have correctly identified a base and its corresponding height? Which ones have not? Explain what is inco
rrect. Explain what is correct.
1 answer:
Answer:
The Explanation is below with correction in the Figure.
Step-by-step explanation:
Height is also call as Altitude.
Height of Triangle always measure in PERPENDICULAR to the Base.
a. )
Raul is correct because Height should always be Perpendicular, and Raul has drawn Height 'h' Perpendicular to the corresponding Base 'b'.
b. )
Mark is incorrect because Height drawn is NOT Perpendicular.
c. )
Kiki is incorrect because the corresponding base is incorrect, Height drawn is correct that is Perpendicular.

Answer:
So the z-scores that separate the unusual IQ scores from those that are usual are Z = -2 and Z = 2.
The IQ scores that separate the unusual IQ scores from those that are usual are 84 and 148.
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 question, we have that:
What are the z scores that separate the unusual IQ scores from those that are usual?
If Z<-2 or Z > 2, the IQ score is unusual.
So the z-scores that separate the unusual IQ scores from those that are usual are Z = -2 and Z = 2.
What are the IQ scores that separate the unusual IQ scores from those that are usual?
Those IQ scores are X when Z = -2 and X when Z = 2. So
Z = -2
Z = 2
The IQ scores that separate the unusual IQ scores from those that are usual are 84 and 148.
