Answer:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
Step-by-step explanation:
Answer:
a (-5,-2)
b (-3,-5)
c (3,-5)
d (5,-7)
e (5,-2)
Step-by-step explanation:
Use Pythagorean theorem
a^2 + b^2 = c^2
You know b = 7, c = 16
Plug in the values
a^2 + 7^2 = 16^2
a^2 + 49 = 256
a^2 = 207
a = 14.38749
Round to nearest tenth
Solution: a = 14.4 in.
