Answer:
The temperature increased until 4:00 p.m. ⇒ true (1st)
The temperature decreased after 6:00 p.m. ⇒ true (3rd)
The temperature increased more quickly between 12:00 p.m. and
4:00 p.m. than before 12:00 p.m ⇒ true (5th)
Explanation:
"I have added screenshot of the complete question as well as the diagram"
- Lets use the graph to answer the question
∵ The time of the graph recorded after mid-night
∵ 4:00 p.m. means 16 using 24-hour system (4 + 12 = 16)
∵ From the graph the temperature increased from 8 till 16
∴ The temperature increased until 4:00 p.m. ⇒ true
∵ Horizontal line in the graph means there is no change in the
temperature from 16 to 18
∵ 16 means 4:00 p.m. and 18 means 6:00 p.m.
∴ The temperature was not recorded between 4:00 p.m. and
6:00 p.m. ⇒ not true
∵ The temperature at 18 (6:00 p.m.) = 8°F
∵ The temperature at 20 (8:00 p.m.) = 4°F
∴ The temperature decreased after 6:00 p.m.
∴ The temperature decreased after 6:00 p.m. ⇒ true
∵ The temperature increased from 8:00 a.m. to 12:00 p.m. by 4°F
∵ The temperature increased from 12:00 p.m. to 4:00 p.m. by 8°F
∴ The temperature increased and then decreased before holding
constant. ⇒ not true
∵ The rate of increased of the temperature from 12:00 p.m. to 4:00
is 8°F/(16-12)hours = 8/4 = 2°F per hour
∵ The rate of increased of the temperature before 12:00 is
4°F/(12-8)hours = 4/4 = 1°F per hour
∴ The temperature increased more quickly between 12:00 p.m.
and 4:00 p.m. than before 12:00 p.m ⇒ true
