Answer:
AB and EF are the ones parallel to HG
Step-by-step explanation:
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.

10x10 = 100 the entire square
but there is a 5x5 square that is not shaded so 100- 25 is 75 . The answer is 75 square feet
Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is 
the sum of the chords' intercepted arcs.
m∠BPD = (M∠BD + M∠CA)
= (70 + 170)
= (240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°
Answer:
-2
Step-by-step explanation:
sec 180 + sin 270 - tan 180 + cot 270
= -1 + (-1) - 0 + 0
= -1 + (-1)
= -2
