The question is:
A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups
of flour 1 cup of suger and 2 cups of chocolate chips how much of each
ingredient should be used to make 2 dozen cookies?
find ratio
for 3 dozen batches, you need 3 cups of flour
so dozen of batches=number of cups of flour
then 3 dozen batches is 1 cup of sugar
so every dozen batches is 1/3 cup sugar
then 3 dozen batches is 2 cups choc chips
so every dozen is 2/3 cups choc chips
for 2 batches
that is 2 cup of flour
2/3 cup of sugar
and 4/3 cup chocolate chips
Answer: 
Step-by-step explanation:
You need to use the following formula to calculate the volume of Triangular prism:

Where "a" is the area of one triangular base and "h" is the height of the triangular prism.
Calculate "a" with this formula:

Where "b" is the base of the triangle and "H" is the height.
In this case:

Then, substituting values, you get that the area is the following:

Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute
, which is its height:

Answer:
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Step-by-step explanation:
We know:
-A normal distribution
-Mean μ = 69.0 in
-Standard deviation σ = 2.8 in
- Population n = 350
And doors height 72 in
If passengers will pass through the door without bending that means he must be under 72 in tall, therefore we are looking for the probability of men under 72 in, to find such probability we compute the value of Z according to
Z = ( X - μ ) / σ ⇒ Z = ( 72 - 69 ) / 2.8
Z = 1.07
Now with this value we look the Z tables, to find a value of: 0.8577
So the probability of select a men and that he can fit through the door is
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
