Answer:
a) 0.00019923%
b) 47.28%
Step-by-step explanation:
a) To find the probability of all sockets in the sample being defective, we can do the following:
The first socket will be in a group where 5 of the 38 sockets are defective, so the probability is 5/38
The second socket will be in a group where 4 of the 37 sockets are defective, as the first one picked is already defective, so the probability is 4/37
Expanding this, we have that the probability of having all 5 sockets defective is: (5/38)*(4/37)*(3/36)*(2/35)*(1/34) = 0.0000019923 = 0.00019923%
b) Following the same logic of (a), the first socket have a chance of 33/38 of not being defective, as we will pick it from a group where 33 of the 38 sockets are not defective. The second socket will have a chance of 32/37, and so on.
The probability will be (33/38)*(32/37)*(31/36)*(30/35)*(29/34) = 0.4728 = 47.28%
The answer to the question is 300 square feet
Answer:
Step-by-step explanation:
Hello, please consider the following.
A. (x minus y)(y minus x)
This is not a difference of squares.
B. (6 minus y)(6 minus y)
This is not a difference of squares.
C. (3 + x z)(negative 3 + x z)
This is a difference of squares.
D. (y squared minus x y)(y squared + x y)
This is a difference of squares.
E. (64 y squared + x squared)(negative x squared + 64 y squared)
This is a difference of squares.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Knowns:
C = mx + b
m = 367
b = 1500
C = 367x + 1500
Cost (c) = 16,600
16600 = 367x + 1500
subtract 1500 from both sides
15,100 = 367x
Divide both sides by 367
x = 41.14
