Answer:
0.8041
Step-by-step explanation:
We know that
μ=72 and σ=5
and P(65<X<78)
We can determine the Z value as (X-μ)/σ
P( 65<X<78 )=P( 65-72< X-μ<78-72)
To fine the Z values:
From the standard normal tables:
to find P ( Z<-1.4)
From the standard normal tables:
Therefore
Answer:
3/10 yds per piece
Step-by-step explanation:
Take the amount of fabric and divide by the number of pieces
9/10 ÷ 3
Copy dot flip
9/10 * 1/3
9/30
Divide the top and bottom by 3
3/10 yds
It is -15 = c
