Answer:
7(x+5)-(2xy^2)
Step-by-step explanation:
"The product of 7" means multiplied by 7
"The sum of x and 5" implies addition
"minus the product of 2, x, and the square of y" means 2, x, and the square of y are all multiplied together subtracted from 7(x+5)
Hope this helps.
The standard deviation is 2.6832815729997
SD^2=(12-12)^2+...+(14-12)^2/10
SD^2=72/10
SD^2=7.2
SD=squeare root of 7.2
SD=2.6832815729997
y> -x+ 2.
66
It's given that
Tn = 5n + 16
The 10th term is
T10 = 5(10) + 16
= 66
