It should be y=x Good luck!
Step-by-step explanation:
let the number of cookies sold on first week be=x
let the number of cookies sold on second week be= x+4
let the number of cookies sold on third week be= (x+4)×2
total number of cookies sold = 351
now 351=(x)+(x+4)+(x+4)×2
351=3x+(4+4×2)
351=3x+12
3x=351-12
3x=339
x=339÷3
x=11
Cookies sold on first week=113
Cookies sold on second week= 113+4= 117
Cookies sold on third week =113+4×2 = 113+8=121
now add all the number of cookies solved for confirmation
=113+ 117+ 121= 351
Answer:
62,500 pi
Step-by-step explanation:
diameter = radius + radius
d = 2r
r = d/2
A = 4pi r^2
= 4 pi (d/2)^2
= 4pi d^2/4
= 4pi* 250^2/4
= 4pi * 62,500/4
= 4pi * 15625
= 62,500 pi
Answer:
So it wants you to first find the mean (average) of the data set, then find the distance everything is from the mean (average).
Step-by-step explanation:
3+5+9+14+16+18= 65
65 divided by the amount of numbers you put in (6) = 10.83 rounded to the nearest hundreth
So now we know the mean (average) now we need to see how far away each number is from the mean (average).10.83-3 is 7.83. 10.83-5 is 5.83. 10.83-9 is 1.83. 10.83-14 is -14.17, but -14.17 would be a normal 14.17 because it wants the absolute value. 10.3-16 is -5.17 (of course keep it as a positive), and finally 10.83-18 is -7.17 as a positive. Now for the mean absolute value of the data they likely mean from 0, so it would be 10.83.
Hope it helped and wasn't too confusing :)
