Answer:
10a^2b^3−8a^3b^3+12a^2b^5−8ab^4
Step-by-step explanation:
// Plug x into the equation
5(0.3)+2y=20
1.5+2y=20
// Subtract 1.5 from each side
2y=18.5
//Divide each side by 2
y=9.25 (C)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
True mean(μ) = 77.9
True standard = 20
Sample size (n) = 50
Sample mean (m) = 82.1
Sample standard deviation (s) = 18.6
The standard error (SE) :
SE = sample standard deviation / √sample size
SE = 18.6 / √50
SE = 2.6304372
SE = 2.63
The answer is $14 dollars an hour. How i did that is you just have to $14 x 8=$112 and the 1/2 hours of the 7$. So the total is $112
