X = 42
x/3 - 4 = 10
+ 4 +4
x/3 = 14
•3 •3
x = 42

Answer:
Range: (844.9,1333.7)
A brain volume of 1348.3 cm cubed can be considered significantly high.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 1083.9 cm cubed
Standard Deviation, σ = 122.2 cm cubed
Range rule thumb:
- This rule state that the the range of data is four times the standard deviation of the data.
Upper Limit:
Lower limit:
Since, 1348.3 does not lie in the range (844.9,1333.7), a brain volume of 1348.3 cm cubed can be considered significantly high.
During one hour of television there are two shows on. That would be the ratio 1:2. We need to find 3:?. Since 1×3 is 3, we multiply the second number by 3 as well. 2×3 is 6. So the ratio would be 3:6.
