Answer:
Step-by-step explanation:
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.
X = 40 min
y = 10 min
x = 40/60 h --> x = 4/6 h --> x = 2/3 h
y = 10/60 h --> y = 1/6 h
x + y = 2/3 - 1/6
x+y = 4/6 - 1/6
x+y = 3/6 h = 3*60'/6 = 3*10 = 30 min
The volume of a cube is Side ^3
Find the cubic root of the volume to find the side length:
Side = cubicroot(216) = 6 feet.
The area of a face of a cube is s^2
Area of a face = 6^2 = 36 square feet.
Area of 2 faces = 36 x 2 = 72 square feet
Answer: 72 square feet
