Step-by-step explanation:
1) for t = 0, the initial value is -0.45 gal. which is funny. when it is really cold, do people add water to the tank somehow instead of consuming water ?
so I guess, that system is really reliable with values greater than 0.
0.0875t = 0.45
t = 5.142857143...°
so, I guess, 6° is the lowest reasonable value for this function.
2) as for any line function, the slope is the rate of change.
so, 0.0875 gal more per 1 degree more in temperature.
3) t = 90
w = 0.0875×90 - 0.45 = 7.425 gal
Answer:
5th term = 20
6th term = 23
Step-by-step explanation:
nth term = 3n + 5
Find the 5th term
When n = 5
5th term = 3n + 5
= 3(5) + 5
= 15 + 5
= 20
5th term = 20
Find the 6th term
When n = 6
6th term = 3n + 5
= 3(6) + 5
= 18 + 5
= 23
6th term = 23
negatively skewed
Step-by-step explanation:
The long "tail" is on the negative side of the peak. Or simply put, it is skewed to the left.
Hope this helps.
Answer:
7/12
Imagine this:
you had a block set with 12 blocks in it
you built a tower with 5 blocks (5/12)
You have 7 blocks left (7/12)
5/12 + 7/12 = 12/12 = 1
