Answer:
Company B is more likely to produce a box of 260 roofing nails.
Step-by-step explanation:
Company A :
Mean = 272 nails
Standard deviation = 5.4 nails
Roofing nails expected to be produced = 260
⇒ 260 = 272 + z × 5.4
⇒ z = -2.222
Hence, Company A has a chance of 1.32% of producing exactly or fewer than 260 boxes of roofing nails.
Company B :
Mean = 249 nails
Standard deviation = 3.8 nails
Roofing nails expected to be produced = 260
⇒ 260 = 249 + z × 4.8
⇒ z = 2.895
Hence, Company B has a chance of 0.19% of producing exactly or more than 260 boxes of roofing nails.
Therefore, Company B is more likely to produce a box of 260 roofing nails.

Answer:
The fraction of the students that walk in in Marla's school is equal to 
Step-by-step explanation:
Let
x------> the total students in Marla's school
we know that
The number of students that not ride the bus is equal to

The number of students that walk to the school is equal to

therefore
The fraction of the students that walk in in Marla's school is equal to 
1434 * 44444 = 63,732,696
This is multiplication that can be performed either by hand or with a calculator. If you have a more specific question about a more in-depth problem, post it and I would be happy to give you a better explanation of that multiplication.
Hope this helps!
