Let's calculate the z scores for 42 and 58:
42 - 50
z = ------------- = -1
8
58-50
z = --------------- = 1
8
so the question becomes: what percent of the data should fall within 1 std. dev. of the mean? Referring to the empirical formula: 68% (answer)
To solve this problem, you must plugin the value g(x) into f(x). This gives you (x-3)^2. When you solve that, it gives you x^2 - 6x + 9.
Consider velocity due east as along the positive x-axis.
Therefore.
The velocity of the bug is, v = + 0.25 m/s
The easterly breeze has velocity, u = - 0.25 m/s
The resultant velocity of the bug is
v + u = 0.25 + (-0.25) = 0.25 - 0.25 = 0.00
Answer: A. 0.00 m/s
Usually the general convention for positive rotations tends to be clockwise whereas the opposite would be counterclockwise.
Answer: The angles are 80 and 100.
Step-by-step explanation:
Total angles for a supplementary angle is 180°.
Since the angles are in 5:4
5/9 × 180= 100
4/9 × 180= 80
