Answer:
import pandas as pd
vec = pd.Series([7.12,24,4,18,12,9])
vec.plot(kind = 'hist')
Step-by-step explanation:
You can use python for that.
By doing
import pandas as pd
vec = pd.Series([7.12,24,4,18,12,9])
vec.plot(kind = 'hist')
And this is the result you get
You would just decide both sides by 2.
-x = -9/3 ⇨ -3
Since both numbers are negative, the product becomes a positive.
x=3
Hope this helped!

First, replace

and

. Then you have

If we take

, then immediately we see a differential in the numerator in the form of

. So the integral becomes

and evaluates to

making (A) the correct answer.
Answer:
The answer to your question is: 54°F
Step-by-step explanation:
Data
Ti = 78°F
Initial hour = 2:00
Temperature drops 4°F every hour
Temperature at 8:00 = ?
Process
2:00
3:00 78-4 = 74°F
4:00 74-4 = 70°F
5:00 70-4 = 66°F
6:00 66-4 = 62°F
7:00 62-4 = 58°F
8:00 58-4 = 54°F
