Answer:
168 = x
Step-by-step explanation:
mean = u=132
standard deviation =sigma = 20
z score =z=1.8
The formula is
z = (x-u)/ sigma
Substituting what we know
1.8 = (x-132)/20
Multiply by 20
1.8*20 = (x-132)/20 *20
36 = x-132
Add 132 to each side
36+132 = x-132+132
168 = x
Answer:
x>-14

Answer:
Y=( x/2 )- 5
Where y is the number of pencils given to Jamil and 5 is the one kept by Maggie.
Step-by-step explanation:
Let's call the number of Katie pencil (x ).
So Katie gave half of her pencils to Maggie.(1/2x)
So Maggie keeps five pencils and give the rest to Jamil.
So
X/2 = 5 + y
Where y is the number of pencils given to Jamil and 5 is the one kept by Maggie.
Y=( x/2 )- 5
