Answer:
The Answer is C
Step-by-step explanation:
This applies to your exam.
Basically solve for y
minus 5x fromboth sides
-15y=-5x-60
divide both sides by -15
y=1/3x+4
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The proportion of total part-time workforce is
The sample size is n = 80
Generally the mean is mathematically represented as
The proportion of not part - time workforce
=>
=>
The standard deviation is mathematically represented as
Now applying the normal approximation,
Then the probability that fewer than 20 people from this sample were between the ages of 25 and 34 is mathematically represented as
Applying continuity correction
Generally
So
From the z-table
The probability is
Answer:
x = -52
y = -11
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Hence:
x+y=-63
x-y=-41
y = x+41
(Apply Simultaneous Equations)
x+(x+41)=-63
2x+41=-63
2x=-63-41
2x=-104
x=-104/2
x=-52
Now:
y=-52+41
y=-11
