Huh? What does this mean?
Answer:
1.) 10000, -3, 1000 ; doesn't make sense
2.) 40000, 3, 40000 makes sense
3.) 32500, 1.5, 32500 makes sense
4.) [0,+ ∞ ]
Step-by-step explanation:
1.) r(-3) = 2500 - 3*5000=10000
2.) f(3) = 25000 + 3*5000 = 40000
3.) f(1.5) = 25000 +1.5*5000= 325000
4.) # of siblings must >= 0
Hey there!

If he is going to cut it into 5 equal pieces then we need to divide 105 by 5.
105 ÷ 5 = 21
So, each piece will be 21 feet long.
Hope this helps!
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
- 5 square root 2 / 2 for the first one
+ 5 square root 2 / 2 for second one
