Answer:
25.25%
Explanation:
Mean diameter (μ) = 0.35 inches
Standard deviation (σ) = 0.03 inches
For any given diameter, X, the z-score is given by:
For X= 0.37 inches:
A z-score of 0.6667 is equivalent to the 74.75-th percentile of a normal distribution.
Therefore, the percentage of bolts that will have a diameter greater than 0.37 inches is:

Answer: 3 seconds
Explanation: since 3 is 4 away from 7, 3 times 1.5 is 4.5 which is the closest you can get to 7 without being below 7
Lets do the sum of the forces about the elbow joint.
Fm = Force of Muscle; Fe = Force Elbow; Fb = Force Ball
Sum Force about Joint = (-2.5)Fm + 12.5Fe + 30Fb = 0
(-2.5)Fm + 12.5(2.8) + 30(6.9) = 0
Fm = 96.8kg
Fm = 96.8 * 9.8 = 948.6N
Do you understand why the -2.5 is negative?
<span>
Because I put the origin at the joint. So when you go left it is negative and when you go right it is positive. </span>
