<u>Answer:</u>
The temperature change per hour was -3 degrees per hour.
<u>Step-by-step explanation:</u>
We know that the temperature fell from
degrees to
degrees in a time period of
hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:

Temperature change per hour = 
Therefore, the temperature change per hour was -3 degrees per hour.
The answer would be -8+-88a
Answer:

Step-by-step explanation:
1) The order of selection matters. Therefore we need to find the number of permutations of 11 members taken 3 at a time. 11P3 = 990 ways.
Answer choice B) is correct.
2)The order of selection matters. Therefore we need to find the number of permutations of 12 members taken 4 at a time. 12P4 = 11,880.
Answer choice C) is correct.
