Have an average weight of 16 ounces and a standard deviation of 0.2 ounces. the weights of the sugar bags are normally distribut
Oliga [24]
Standardised z score = (16.075 - 16) / 0.2  =  0.375

which gives a probability of 0.1462  for  selecting a package of weight 16.075

the probability of weight being excess of 16.075 = 0.5 - 0.1462 =  03538

Probability of picking 16 in excess of 16-075 = 0.3538^16 =  6.0273 * 10^-8

A box on a 20 degree incline is shown with vectors radiating from a point in the center of the box. The first vector points up a
Finger [1]

The images to solve this problem is in the attachment.

Answer: F_{fs} = 671.0 N; F_{N} = 300 N

Step-by-step explanation: From the image in the attachment and knowing that the box is in equilibrium, i.e., the "sum" of all the forces is 0, it is possible to conclude that:

F_{fs}  = F_{gx} and F_{N} = F_{gy}

Using trigonometry, shown in the second attachment, the values for each force are:

  • Force of Static Friction

sin 20° = \frac{F_{gx} }{F_{g} }

F_{gx} = F_{g}. sin(20)

F_{gx} = 735.0.913

F_{gx} = 671.0

  • Normal Force

cos 20° = \frac{F_{gy} }{F_{g} }

F_{gy} = F_{g}. cos (20)

F_{gy} = 735.0.408

F_{gy} = 300

The force of static friction is 671N and normal force is 300N
