The most accurate way would be the fourth answer, because to estimate 66% of 47 you need to round both as closely as possible. 66% rounds closest to 2/3, and 47 is closest to 48
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.
The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.
<h3>What are the side lengths of the first triangle?</h3>
The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:
- 5 inches + 5 inches + 4 inches + 4 inches
<h3>What are the side lengths of the new triangle?</h3>
5 inches x 4 = 20 inches
4 iches x 4 = 16 inches
<h3>What is the new perimeter?</h3>
20 + 20 + 16 +16= =72 inches
