Answer:
9.18%
Step-by-step explanation:
First, find the z-score.
z = (x − μ) / σ
z = (18 − 19.6) / 1.2
z = -1.33
Use a chart or calculator to find the probability:
P(Z < z) = 0.0918
Answer:
5000
Step-by-step explanation:
Given the question :
The size of debt after m months is respresented by the expression :
36,700 - (5000 + 500m)
Since Michael has decided to dedicate the entirety of his signing bonus towards paying his debt, then that is a constant and one-off payment.
Also, a fixed portion of his salary each month has also been assigned towards paying off his debt,
Then the amount paid from his salary after a certain number of months will be:
Fixed amount × number of months = 500 × m
Amount paid using signing bonus will be a constant = 5000
Total debt amount = 36,700
Size of debt left after m months :
Total debt - ( signing bonus - fixed amount × m)
Hence signing bonus = 5000
This is not possible, unless x = 1.
Answer:
x = 0
Step-by-step explanation:

Expanding the left hand side we get

Taking 6 from left hand side to right hand side

Dividing both sides by 2

So, x = 0
8(4x+6y-2z)
32x+48y-16z
Hope this helps!
