Answer:

Step-by-step explanation:

87° + x° = 180°

x° = 180° - 87°

x° = 93°

Answer:

x = 93

Step-by-step explanation:

The measure of a straight line is 180°. So,

x + 87 = 180

Subtract 87 from both sides.

x = 93

Alice studies the relationship between climate and heart disease around the world. H(t)H(t)H, left parenthesis, t, right parenth

ddd [48]

Answer:

The domain of the function H(t), is [-5, 30].

The range of the function H(t), is [(10% + average), (average - 20%)]

Step-by-step explanation:

The domain of a function is the complete set of possible values of the independent variable.

For this question, the function is H(t), with the temperature, t, serving as the independent variables and H(t) the evidently dependent variable.

The domain of a function refers to all the possible independent variable values that will give corresponding real dependent variable values.

For this question, Alice's model has the probability for the occurrence of heart disease (in percents relative to the global average) at an area, H(t) varying with the temperature of that area in degree Celsius.

At a temperature of -5°C (the lowest temperature in the model), the probability is 10% above the average.

Then, the probability decreases with increase in temperature, taking a value 20% lower than the average when the temperature is at its highest of 30°C in the model.

So, temperature ranges from -5°C to 30°C and the probability for the occurrence of heart disease ranges from 10% above the average to 20% below the average.

The domain of the function H(t), from the definition given above would therefore be [-5, 30]

And the range of the function H(t), is [(10% + average), (average - 20%)]

Hope this Helps!!!

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean

mrs_skeptik [129]

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.

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 $\mu$ is 98.34 and the standard deviation $\sigma$ is 0.59. So:

Minimum

$Mi = \mu - 3\sigma = 98.34 - 3(0.59) = 96.57$

Maximum

$Ma = \mu + 3\sigma = 98.34 + 3(0.59) = 100.11$
