a) The following exponential model would fit the given dataset : 
b) To cool down to 110 degrees, it would take approximately 7.3 minutes based on the above model.
4/32 = x/100
answer: x = 12.5
The proper name of the quadrilateral is called Parallelograms
Answer:
30cm
Step-by-step explanation:
Area is πr²
So,
πr²=225π
r=√225
r=15cm
Diameter=2r=30
Maths is easy peasy
To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2 The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2 2=0 away from 2 4=2 away from 2
You should get: 1,1,0,0,0,2 Next, you have to find the mean of the new set of numbers. 1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3
