Okay so Average Rate of Change is what it says;
It's the average of the rate of change
Change can be represented by a - b, for example, if I start 2 miles away from my house and I walk until I'm 3 miles away, I can say 3 - 2 = 1, I walked 1 mile
I'm sure you know what the average is, so let's move on
We're asked to find the average rate of change between minutes 25 and 13
In minute 25, the amount of money is 19.50
In minute 13 the amount of money is 16.50
There is 12 minutes between 25 and 13, and there is a $3 difference between $19.50 and $16.50
So, if it's asking for how many minutes per 1 dollar, then we saw a change of 3 dollars over 12 minutes, divide both numbers by three and we get
1 dollar / 4 minutes
Answer:
27) 12
29) 14
Those are the right answers
Answer:
(22.74 ; 27.26)
Step-by-step explanation:
The confidence interval relation is stated as :
Mean ± Zcritical * σ/sqrt(n)
Mean = 25
σ = 6
The Zcritical at 95% = 1.96
Hence,
25 ± 1.96 * (6/sqrt(27))
25 ± 1.96 * 1.1547005
Lower boundary :
25 - (1.96 * 1.1547005) = 22.73678702
Upper boundary :
25 + (1.96 * 1.1547005) = 27.26321298
(22.74 ; 27.26)

Answer:
well, there are three possible answers. 24 square cm, 18 square cm, and 12 sqaure cm.
Step-by-step explanation:
L*W is base, and base times H, Height, gives you the volume of a three dimensional shape. The base depends on what the height is, so if there was a diagram i would be able to help you more. Its either 6*4 with 3 height, 6*3 with 4 height, or 3*4 with 6 height.
Since the question is so vague, I am not sure if thats what you are asking, so heres another answer: you want the combined total of the rectangle if you were to flatten it out. If so, then you have two 24 square cm sides, two 18 square cm sides, and two 12 cm sides. Add this up and you get the total area.
12*2+18*2+24*2 = 108
