Step-by-step explanation:
a)
p(d) - probability of a rivet being defective
p(r) - probability of seam needing to be reworked
The probability of the seem needing to be reworked is equal to the probability that ANY of 24 rivets is defective
Thus the probability that none of the 25 rivets is defective is 1-p(r)
p(r) = 16%, thus 1-p(r) = 84%
1-p(r) = (1-p(d))^24
0.84 = (1-p(d))^24
0.84^(1/24) = 1-p(d)
==> 1-p(d) = 0.9927615998
==> p(d) = 1-0.9927
==> p(d) = 0.0073
b) given p(r) = 8%, thus 1-p(r) = 92%
1-p(r) = (1-p(d))^24
0.92 = (1-p(d))^24
0.92^(1/24) = 1-p(d)
==> 1-p(d) = 0.99653179446
==> p(d) = 1-0.9965
==> p(d) = 0.0035

Answer:
The possible values for x are 4 and 0.25.
Step-by-step explanation:
In order to solve for "x" in the equation we first need to sum "x" and "1/x", to do that we must apply LMC as shown below:
x + 1/x = 17/4
(x² + 1)/x = 17/4
4*(x² + 1) = 17*x
4*x² + 4 = 17*x
4*x² + 4 - 17*x = 0
4*x² - 17*x + 4 = 0
x = [-(-17) + sqrt((-17)² - 4*(4)*(4))]/(2*4) = 4
x = [-(-17) - sqrt((-17)² - 4*(4)*(4))]/(2*4) = 0.25
The possible values for x are 4 and 0.25.
