Based on the time it took the patient to recover and the mean and standard deviation, the z-score is 1.5.
<h3>What is the z-score?</h3>
The z-score for this patient who takes 7 days to recover can be found as:
= (Time taken to recover - Mean) / Standard deviation
Solving for the z-score gives:
= (7 - 5.2) / 1.2
= 1.8 / 1.2
= 1.5
The first part of the question is:
The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 1.2 days.

the correct answer is B
"ice cream at -3 degrees C is cooler than ice cream at 1 degree C"
-3 is smaller than 1
-3 < 1
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.
Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trig ratio:
tan(23) = d/1143
d = 485.2 feet
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
