Which of the following normal curves corresponds to

Upper P left parenthesis Upper X greater than 39 right parenthesis

​?

A.

39

50

A normal curve has a horizontal axis with two labeled coordinates, 39 and 50. The curve's peak is near the top of the graph at horizontal coordinate 50. Two vertical line segments run from the horizontal axis to the curve at horizontal coordinates 39 and 50. The area under the curve to the left of the left vertical line segment is shaded.

B.

39

50

A normal curve has a horizontal axis with two labeled coordinates, 39 and 50. The curve's peak is near the top of the graph at horizontal coordinate 50. Two vertical line segments run from the horizontal axis to the curve at horizontal coordinates 39 and 50. The area under the curve between the vertical line segments is shaded.

C.

39

50

A normal curve has a horizontal axis with two labeled coordinates, 39 and 50. The curve's peak is near the top of the graph at horizontal coordinate 50. Two vertical line segments run from the horizontal axis to the curve at horizontal coordinates 39 and 50. The area under the curve to the right of the left vertical line segment is shaded.

Your answer is correct.

Upper P left parenthesis Upper X greater than 39 right parenthesis
