The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.

Step-by-step explanation:
Its b because blue plus white is 16, so blue and white combined have the same as black
Hope this helps :D
Answer:
<u>Part (a)</u>
see attached for sample space
<u>Part (b) </u>
Total number of possible outcomes = 12
<u>Part (c)</u>
Her activity does not depend on which bus she takes, as we have been told that once she is on the bus, she randomly selects the activity. Therefore, the activity selection is independent from the bus selection.
The sample space confirms this as it shows that the probability of the selecting each activity is equally likely for each of the 4 buses.

B just took it :)
