5x=25
Because negative 3y and positive 3y got cancelled
Y= -3. Someone else had the same question I just answered lol
Solution :
Let :
X = number of overtime hours
S = total weekly salary
S = 
S = 480 + 18X
E(S) = 
= 750
Mean of S = 750
Var (S) = 
Var(S) = 
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72
Answer: Maybe 5.7
Step-by-step explanation: To solve this we are going to need to understand the pythagorean theorem. we can use it as a way to find this certain side. if we put these numbers in the theorem, we get a^2+49=81 (7^2=49 and 9^2=81), we can subtract 49 on both sides and get 32. We would also need to take out the power of 2 on the side of the a^2, so you would do the square root of a^2, which would just become a and the square root of 32, which if you crunch the numbers on a calculator. You would get 5.656..... then you round it to the nearest tenth and get 5.7.
Answer:
1.95
Step-by-step explanation:
Basically, you subtract: 5.82 - 13.87 = 1.95
Then, see: 15.82 - 1.950 = 13.87
Then you have your answer :D
