An aircraft seam requires 22 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are d
SpyIntel [72]

Answer:

Part A:

p=0.0095

Part B:

p=0.0043

Step-by-step explanation:

Part A:

The number of rivets=22 rivets

Probability that no rivet is defective= (1-p)^22

The probability that at least one rivet is defective=1-(1-p)^22

For 19% of all seams need reworking, probability that a rivet is defective is given by:

1-(1-p)^{22}=0.19

(1-p)^{22}=0.81\\p=1-\sqrt[22]{0.81} \\p=0.0095

Part B:

For 9% of all seams need reworking, probability of a defective rivet is:

1-(1-p)^{22}=0.09\\p=1-\sqrt[22]{0.91} \\p=0.0043

If the can of dogfood holds 8 ounces and the bag of dogfood holds 30 times the volume , how many pounds of dogfood does the bag
Maru [420]

Answer:

15 pound in a bag

Step-by-step explanation:

one can= 8 oz

one bag= 30 times the amount in a can

               8 oz x 30 =  240 oz in a bag

Question asked how many pound is in one bag of dog food:

We know that 16 oz = 1 pound

                       240 oz = x pound

To find x pound we divide 240 oz by 16 oz-->

240 oz/ 16 oz = 15 pound
