For this case, the first thing we must do is define variables.
We have then:
h: number of hours
t: temperature
We now write the equation that represents the problem.
We have then:
t (h) = -2h + 32
We note that for h = 0
t (0) = -2 (0) + 32
t (0) = 32
Answer:
An equation that represents the temperature, t, at your h is:
t (h) = -2h + 32
-2/2 = -1/1 = -1
Therefore, the absolute value of -2/2 is -1.
The frequency table that shows the relative frequency of people older than 40 and don't visit the dentist is:
D. Visit Dentist Yearly Don’t Visit Dentist Yearly
Below 40 0.27 0.73
Above 40 0.57 0.43
<h3>What is the relative frequency required?</h3>
The relative frequency of those older than 40 and don't go annually to a dentist can be found as:
= Number of over 40 who don't go to dentist / Total of those over 40 surveyed
Solving gives:
= 13 / (17 + 13)
= 13 / 30
= 0.43
