Step-by-step explanation:
I= PxRxT. 18/12=1.5
I=500x0.06x1.5
I=45
Hi there!
![\large\boxed{x = -3}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3D%20-3%7D)
Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3
Answer:
2.42
Step-by-step explanation:
standard deviation= sqrt(variance)
Variance=E[X2] - E[X]2
E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81
E[X2] =sum(X2)/n = 189/9 = 170/81
Variance= 476/81
Standard deviation = sqrt(476/81) ~2.42
Instead of adding more fraction strips you would take some away to get a smaller number.
Answer:
Step-by-step explanation:
![(3n+2)^{2} = (3n+2)(3n+2)](https://tex.z-dn.net/?f=%283n%2B2%29%5E%7B2%7D%20%3D%20%283n%2B2%29%283n%2B2%29)
- I expanded the above brackets
- I separated the 1 from 4 to make 3+1
- I took out a factor of 3
= 1 more than a multiple of 3
