A.
For 12 - 1,
82 - 78 = 4 degrees per hour
For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour
For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour
For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour
The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change
Y>2 is the 1st one. x>-4 is the 3rd one. Write the inequality. 1. 3, 2. 3
Answer:
25.6 km/h
Step-by-step explanation:
Omani:
First, 1.5 hours = 1 hour and 30 minutes
and 66 miles = 105.6 km (66 x 1.6 = 105.6)
105.6 / 1.5 = 70.4 km/h
Omani's speed is 70.4 km/h
Adedi:
1 hour and 15 minutes is 1.25 hours
she drives 56 km in 1.25 hours
So 56 / 1.25 = 44.8 km/h
Adedi's speed is 44.8 km/h
Difference:
70.4 - 44.8 = 25.6 km/h
Omani is faster than Adedi with 25.6 km/h
To find the median, put the numbers in order to least to greatest, which would be 5, 5, 5, 7, 8, 8, 9. the median is the number in the middle, which is seven. the mode is the number that occurs most often in the set, which is 5 in this case (appears three times). 2. 543.24 in expanded form is essentially pulling the number apart into its different values places. in this case, it would be five hundred plus forty plus three plus two tenths plus four hundredths, which is 500 + 40 + 3 + .2 + .4. hope this helps!
I am not sure, but the best answer should be 8 miles per hour
