1/3 cup of flour is used to make 5 dinner rolls. how many cups of flour are needed to make 3 dozen dinner rolls

MAVERICK [17]

F = Cup of flour

D = Dinner roll(s)

12 = A dozen

36 = Three dozen

---------

1/3 * F = 5 * D

n * F = 36 * D

------

$\frac { 1 }{ 3 } F=5D\\ \\ 3\cdot \frac { 1 }{ 3 } F=3\cdot 5D\\ \\ F=15D$

$nF=36D\\ \\ n=\frac { 36D }{ F }$

This means that...

$n=\frac { 36D }{ 15D } \\ \\ n=\frac { 36 }{ 15 } \\ \\ n=\frac { 3\cdot 12 }{ 3\cdot 5 } \\ \\ n=\frac { 12 }{ 5 } \\ \\ n=\frac { 10 }{ 5 } +\frac { 2 }{ 5 } \\ \\ n=2+\frac { 2 }{ 5 }$

And this means that two cups of flour and 2/5 of a cup of flour are required to make 3 dozen dinner rolls.

describe how to sketch a normal curve with a mean of 50 and a standard deviation of 2 indicate how you would label the horizonta

Zepler [3.9K]

Answer: See below.

You would sketch a traditional bell curve. For middle line (the highest point of the circle), you would label it with the mead of 50.

Going to the right, you would draw 3 vertical lines. The lines would count up by 2 for each standard deviation. 52, 54, 56

Going to the left, you would draw 3 vertical lines. The lines would count down by 2 for each standard deviation. 48, 46, 44
