Anuta_ua [19.1K]

Half of the numbers on the cube are even, so there's a 1/2 chance that that number is even. 3/5 of the numbers on the cards, however, are odd. The chance that both of these occur is 3/5*1/2=3/10.

An aircraft seam requires 24 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are d

ruslelena [56]

Answer:

(a) 0.007238 or 07238%

(b) 0.003468 or 0.3468%

Step-by-step explanation:

(a) Since all it takes is one defective rivet for a seam to be reworked. The probability of a defective rivet 'p' for 16% of seams needing reworking is:

$1-(1-p)^{24} = 0.16\\1-p = \sqrt[24]{0.84}\\p=0.007238$

The probability that a rivet is defective 0.007238 or 0.7238%.

(b) To ensure that only 8% of seams need reworking, the probability 'p' must be:

$1-(1-p)^{24} = 0.08\\1-p = \sqrt[24]{0.92}\\p=0.003468$

In order to ensure that only 8% of all seams need reworking, the probability of a defective rivet should be 0.003468 or 0.3468%.

Evaluate x^2-x for the value of x satisfying 6 (x - 3) + 3 = 6x - 3 (3 - x)

vladimir2022 [97]

Answer:

Step-by-step explanation:

We can first find x:

6 (x - 3) + 3 = 6x - 3 (3 - x)

6x - 18 + 3 = 6x - 9 + 3x

6x - 15 = 9x - 9

We can then islolate x, getting 3x = -6 and x = -2.

We can then plug in -2 for x and solve x^2 - x:

(-2)^2 - 2 = 4 - 2 = 2
