Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
Answer: =2/15
Step-by-step explanation: Hope this help :D
Answer:
There are 89% of healthy adults with body temperatures that are within 3 standard deviations of the mean
The minimum value that is within 3 standard deviations of the mean is 96.57.
The maximum value that is within 3 standard deviations of the mean is 100.11.
Step-by-step explanation:
Chebyshev's theorem states that a minimum of 89% of the values lie within 3 standard deviation of the mean.
So
Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 3 standard deviations of the mean?
There are 89% of healthy adults with body temperatures that are within 3 standard deviations of the mean.
What are the minimum and maximum possible body temperatures that are within 3 standard deviations of the mean?
We have that the mean
is 98.34 and the standard deviation
is 0.59. So:
Minimum

Maximum

100% - 7% - 30% = 63% of people are on the sand
