Answer:

Probability that at least 40 can taste difference between two oils:

P(x ≥ 40) = p( x - µ / ∂ ≥ 39.5 – 30 / √29.1)

              = p( z > 1.76)

               = 1 – 0.9608

               = 0.0392

Step-by-step explanation:

Solution:

Given:

Random sample = n = 1000

Probability of people identify the taste = p = 0.03

Probability that people do not identify the taste is 0.97.

Since np = 1000 x 0.03 = 30

And

nq = n(1 – p) = 970

Verify the condition:

np ≥ 10

1000 x 0.03 ≥ 10

30 ≥ 10

And nq ≥ 10

1000 x 0.97 ≥ 10

970 ≥ 10

Hence conditions are satisfied, it is valid to apply normal approximation to binomial distribution.

µ = 30 and ∂ = √29.1

Probability that at least 40 can taste difference between two oils:

P(x ≥ 40) = p( x - µ / ∂ ≥ 39.5 – 30 / √29.1)

              = p( z > 1.76)

               = 1 – 0.9608

               = 0.0392

Select the correct answer.<br> Which graph shows a function and its inverse?
labwork [276]

Answer:

See below

Step-by-step explanation:

If a function is bijective and 1-to-1, then it will have an inverse function. Consequentially, they will be symmetrical about the line y=x, which is a diagonal line passing through the origin at a 45 degree angle.

None of the graphs look correct though, but it also seems that some options are cut out, so make sure to choose the correct graph given the characteristics I've previously described.
