You align then by place value.
If we divide 360 by the number of sides, 16, we will get the measure of one of the 16 central angles. 360/16 = 22.5. The vertex angle of one of the triangles that makes up this 16-gon is 22.5. That means that each of the base angles measure 78.75. If we put 2 of these triangles next to each other, 2 sides touching, the bases of both those triangles meet to form an interior angle. Two base angles of 78.75 together form the interior angle: 78.75+78.75 = 157.5. An interior angle measures 157.5. The exterior angle then has to measure 180-157.5 which is 22.5, same as the vertex angle of 1 of the triangles that make up this 16-gon.
Answer:
15.87% of blue whales eat more than 5,850 pounds of fish
Step-by-step explanation:
Mean = 5000
Standard Deviation = 850
We need to find P(x>5850) = ?
We can find using z-score
z = x - mean/ standard deviation
z = 5850 - 5000/850
z = 850/850
z = 1
Now, P(x>5850) = P(z>1)
Finding value of P(z>1) by looking at the z-score table
P(z>1) = 0.8413
The normal distribution gives area to the left , so subtracting it from 1 to gain the answer
1-0.8413 = 0.1587
Now, to find percentage multiply it with 100
0.1587 * 100 = 15.87 %
15.87% of blue whales eat more than 5,850 pounds of fish
