When a triangle is a 45-45-90 triangle, the following rules apply:

-the 2 legs are equal lengths
- the length of the hypotenuse is: the square root of 2 x the length of a leg.
- the length of the leg is: hypotenuse divided by the square root of 2.

if the hypotenuse is 10, then 10 divided by the square root of 2 is how you find the leg.

How many g of amino acids are in a 2,000mL total parenteral nutrition of 4.25% travesol (amino acids and 20%dextrose?
kirill115 [55]

Answer:

The  mass of  amino acid present is  85 g

Step-by-step explanation:

From the question we are told that

   The  volume of the total  parenteral nutrition is  V  =  2000 mL

   

Generally the volume of the amino acid present is  

                V_a =  0.0425 *  2000

                V_a =  85 mL

Generally  

               mass  \ \ \alpha  \ \ volume

So the mass of amino acid present is 85g

Using the set of data below, which statements are true? Check all that apply. 13, 11, 16, 12, 42, 8 The mean of this data set is
Iteru [2.4K]
8, 11, 12, 13, 16, 42

Add together and divide by 6 to get the mean.

102/6 = 17

Find the middle of the data for the median.
(12 + 13)/2 = 12.5

The mean is 17, the median is 12.5, and the mean is more affected by the outlier.  17 (the mean) is not a good measure of center.
