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:

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

Kailee paid $14.84 for stamps. The number of .49-cents stamps was four less then three times the number of 21-cent stamps. How m

Akimi4 [234]

Answer:

Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.

Step-by-step explanation:

Given:

Total Money paid for stamps = $14.84

Let the number of 49-cents stamps be x.

Also Let the number of 21-cents stamps be y.

Now Total Money paid is equal to sum of number of 49-cents stamps and number of 21-cents stamps.

100 cents = 1$

So 49 cents = $0.49

and 21 cents = $0.21

Hence equation be framed as;

$0.49x+0.21y =14.84 \ \ \ \ equation \ 1$

Also Given:

number of .49-cents stamps was four less then three times the number of 21-cent stamps.

hence we can say that;

$x=3y-4\ \ \ \ equation \ 2$

Now Substituting the value of equation 2 in equation 1 we get;

$0.49(3y-4)+0.21y=14.84\\1.47y- 1.96+0.21y=14.84\\1.68y=14.84+1.96\\1.68y = 16.8\\y=\frac{16.8}{1.68}=10$

Now substituting the value of y in equation 2 we get;

$x=3y-4\\x=3\times10-4\\x=30-4\\x=26\\$

Hence Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
