Answer:
3780 feet
Step-by-step explanation:
49/7*60*3(be careful that it is 3 minutes,not seconds)
=1260
Now,we have to convert yards into feet.
1260 yards = 3780 feet
Because feet is three times yard.
Hope this answer helps! ;)

<h2>
Answer:</h2>
The probability that a defective component came from shipment II is:

<h2>
Step-by-step explanation:</h2>
Let A denote the event that the defective component was from shipment I
Also, P(A)=2%=0.02
and B denote the event that the defective component was from shipment II.
i.e. P(B)=5%=0.05
Also, P(shipment I is chosen)=1/2=0.5
and P(shipment II is chosen)=1/2=0.5
The probability that a defective component came from shipment II is calculated by Baye's rule as follows:

Hence, the answer is:

For the answer to the question above the probability of exactly x successes is
P(X=x)=b(x;n,p) = (nCx)(p^x)((1-p)^(n-x))
where nCx is number of combinations of n things taken x at a time, and "^" means exponentiation.
n = 10
p = 0.2
P(X=7) = 10C7*(0.2^7)*(0.8^3) = 0.00079
P(X=8) = 10C8*(0.2^8)*(0.8^2) = 0.00007
P(X=9) = 10C9*(0.2^9)*(0.8^1) = 0.00000
P(X=10) = 10C10*(0.2^10)*(0.8^0) = 0.00000
.00079 + .00007 + 0 + 0 = .00086 = .0009 rounded
Answer:
The set of numbers of the form
, q≠0 and q≠ 1 or -1.
Step-by-step explanation:
We have that,
U = the universal set = the set of all rational numbers
S = set of all integers.
It is required to find
.
Now,
is the complement of the set S.
i.e.
= U - S = set if rational numbers - set of integers
i.e.
= the set of rationals which are not integers i.e. the set of points of the form
, q≠0 and q≠ 1 or -1.
