Answer:

The probability that a randomly selected American Airlines flight does not arrive on time is 0.197.

Step-by-step explanation:

The probability of the complement of an event <em>E</em> is the probability of it not happening.

That is,

P(E^{c})=1-P(E)

It is provided that the probability of American Airlines flights arriving on time  (<em>X</em>) is,

P(X) = 0.803

Then the event of American Airlines flights not arriving on time is the complement of the event <em>X</em>.

Compute the probability of the complement of event <em>X</em> as follows:

P(X^{c})=1-P(X)=1-0.803=0.197

Thus, the probability that a randomly selected American Airlines flight does not arrive on time is 0.197.

HELP!! Identify the transformation from ABC to A'B'C'.
elena55 [62]

Answer:

<em>Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.</em>

<em>Choice 1.</em>

Step-by-step explanation:

<u>Reflection over the x-axis</u>

Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).

The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.

X has a normal distribution with the given mean and standard deviation. Find the indicated probability. (Round your answer to fo
lapo4ka [179]

Answer:

0.6247

Step-by-step explanation:

The formula for calculating a Z-score is Z = (X - μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

From the question,

μ = 51, σ = 10. We are to find P(36 ≤ X ≤ 56)

Step 1

Find the Probability of X ≤ 36

μ = 51, σ = 10

Z = (X - μ)/σ

Z = 36 - 51/ 10

Z = -15/10

Z = -1.5

We find the Probability of Z = -1.5 from Z-Table

P(X <36) = P(X = 36) = P(Z = -1.5)

= 0.066807

Step 2

Find the Probability of X ≤ 56

μ = 51, σ = 10

Z = (X - μ)/σ

Z = 56 - 51/ 10

Z = 5/10

Z = 0.5

We find the Probability of Z = 0.5 from Z-Table:

P(X < 56) = P(X = 56) = P(Z = 0.5)= 0.69146

Step 3

Find P(36 ≤ X ≤ 56)

P(36 ≤ X ≤ 56) = P(X ≤ 56) - P(X ≤ 36)

= P( Z = 0.5) - P(Z = -1.5)

= 0.69146 - 0.066807

= 0.624653

Approximately to 4 decimal places , P(36 ≤ X ≤ 56) = 0.6247
