Answer: 95% of adult males have diastolic blood pressure readings that are at least 102 mmHg
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 82 mmHg and the standard deviation is 10 mmHg.
2 standard deviations = 2 × 10 = 20
82 + 20 = 102 mmHg
Therefore, 95% of adult males have diastolic blood pressure readings that are at least 102 mmHg.
Given:
tan x = 3/y
cos x = y/z
Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
= (3/y)*(y/z)
= 3/z
Answer: a) sin x = 3/z
A rational number because any number between two integers is a fraction.
Answer:
C
Step-by-step explanation:
5*5+12*12=13*13
25+144=169
169=169
