Answer:

14 boxes

Step-by-step explanation:

We are given that he needs 3 rows with 63 tiles per row.

Hence total number of tiles needed:

= 3 rows x 63 tiles per row

= 189 tiles

we are also given that tiles come in boxes of 14 tiles.

Hence the number of boxes of tiles needed,

= 189 tiles ÷ 14 tiles per box

= 13.5 boxes

but because he cannot just buy 0.5 of a box (i.e he needs to buy whole boxes), we must round this number up to the next whole box

hence

13.5 boxes rounded up to next whole box = 14 boxes.

gulaghasi [49]

Answer:

1.60 L of 10% solution

0.40 L of 35% solution

Step-by-step explanation:

If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:

x + y = 2

0.10x + 0.35y = 0.15(2)

Solve with substitution:

0.10x + 0.35(2 − x) = 0.15(2)

0.10x + 0.70 − 0.35x = 0.30

0.40 = 0.25x

x = 1.60

y = 0.40

Naddika [18.5K]

Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 )  = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ  ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725  

<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>

p ( X < 725 ) = p (( X - μ )/ б √n  <  725 - 750 / 55√25 )

                     = P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116  ( using Z-table )
