Answer:
wheres "M"
Step-by-step explanation:
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:
The combined length is 61 inches
Step-by-step explanation:
we know that
To find out the combined length of all the pieces Meg measured, multiply each measure by the number of pieces and then sum all the values
Let
x -----> the combined length
we know that
we have
1 piece of 3 inches
2 pieces of 5 inches
3 pieces of 6 inches
3 piece of 7 inches
1 piece of 9 inches
so
therefore
The combined length is 61 inches
