We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
Answer:
42
Step-by-step explanation:
The measure of angle K is 48, the measure of angle m is 90. From there you have 138 degrees. A triangle is 180 degrees. You subtract 138 from 180.
We are asked to determine the number of elements in the set containing whole numbers between 3 and 15. In this case, the numbers included in the set are 4,5,6,7,8,9,10,11,12,13,and 14. Upon counting, there are 11 elements all in all. Hence the answer to this problem is A. 11
Answer:
8$ per hour
Step-by-step explanation:
This is a fraction equal to
68 $ ÷ 8.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8.5
68 $ ÷ 8.5
= ------------
8.5 hours ÷ 8.5
= 8 $
--------
1 hour
= 8 $
-------
hour
= 8 $ per hour
