Step-by-step explanation:
Let
b=number of two storey houses,
t=number of three storey houses,
the total number of stories on Algebra Avenue is 95 more than the total number of houses on Algebra Avenue.
2b+3t-95=b+t =>
b+2t=95 .................(1)
The number of two-story houses is three times greater than the number of three-story houses.
b=3t .....................(2)
Substitute (2) in (1)
3t+2t = 95
5t=95
t=19 ......................(3)
substitute (3) in (2)
b=3t=3*19 = 57 .........(4)
Substitute (3) & (4) in (1)
b+2t=57+2*19=95 checks
Substitute (3) & (4) in (2)
b=3t=3*19=57 checks.
Your answer would be -12 because of her answers
Z-score for 80% to pass = -0.842.
-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.
2 3/8
