Answer/Step-by-step explanation:
11/2z+9/5=1.8+12z-6.5z
We move all terms to the left:
11/2z+9/5-(1.8+12z-6.5z)=0
Domain of the equation: 2z!=0
z!=0/2
z!=0
z∈R
We add all the numbers together, and all the variables
11/2z-(5.5z+1.8)+9/5=0
We get rid of parentheses
11/2z-5.5z-1.8+9/5=0
We calculate fractions
<u>There is no solution for this equation</u>
Y=2×+13
2×+3=0
2×=0-3
you use 3 to divide it self =×
×=3
Solution
Given
mean = 251
standard deviation = 33
(a)
Hence, X = 300
(3,-1)
