First, we must find what percent of 7,000 is 160.
To do this, let's do 160/7,000
160/7000 simplified is 4/75.
So, 4 out of every 75 CDs will be defective. If we want to find the probability of them all being affective, we must first do 71/75, because we subtracted the amount of defective CDs from the numerator.
Next week must multiply 71/75*71/75*71/75*71/75*71/75 to get the probability of 5 randomly selected ones being affective.
I got 1804229351/2373046875
If you divide this, you get 0.76030076354, so there is about a 76 percent chance of having all 5 randomly pulled be affective.
.Hope this helped! Comment if you have any questions!!!

Step-by-step explanation:
CD = AB
the inner angle at C = 25° = the outer angle at A.
so, the inner angle at A = 90 - 25 = 65°
now we use the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
with a, b, c being the triangle sides, and A, B, C the angles opposite of the correlated sides.
so, in our case
555/sin(65) = AB/sin(25) = CD/sin(25)
CD = 555×sin(25)/sin(65) = 258.8007503...
≈ 258.8 m
Substituting 4 in place of Y would make the equation 8x-2(4)=48. The value of X is 7.
