Which statements are true about the temperatures luis
recorded on the graph? check all that apply.
the temperature increased until 4: 00 p. m.
the temperature was not recorded between 4: 00 p. m.
and 6: 00 p. m.
o the temperature decreased after 6: 00 p. m.
the temperature increased and then decreased before
holding constant.
the temperature increased more quickly between 12: 00
p. m. and 4: 00 p. m. than before 12: 00 p. m.

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)

Step-by-step 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

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
