A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% sol

solmaris [256]

Answer:

$A=300ml$

Step-by-step explanation:

From the question we are told that

5% solution of dextrose sugar in water

20% solution of dextrose in

100 milliliters of distilled water water

Generally in mathematically solving we call A the amount of D20W added

Since 20% of dextrose is needed

$20 \%*100=20milliter$

Total quantity after addition (100+x)

for DW5% total solution is

$5\% (100+A)= \frac{5}{100}(100+A)$

$5\% (100+A) =5+0.05A$

Mathematically

$5+0.05A =20$

$5+0.05A =20-5$

$A=\frac{15}{0.05}$

$A=300ml$

Therefore the required quantity $A=300ml$

Write an equation of the line that passes through (-3,3) and is perpendicular to the line 2y = 8x - 6

Aliun [14]

Y=4x-3
M of new line = -1/4

y=(-1/4)x+b
3=(-1/4)(-3)+b
3=(3/4)+b
b=9/4

y=(-1/4)x+(9/4)

Find the value of X that makes lines L and M parallel.

Nonamiya [84]

Answer:

x = 11

Step-by-step explanation:

If the lines were parallel, then the transversal would make 2x + 1 and 23° alternate interior angles. Alternate interior angles equal one another, so set up the following equation.

$2x+1=23~(Given)\\\\2x+1-1=23-1~(Subract~1~on~both~sides)\\\\2x=22~(Simplify)\\\\\frac{2x}{2}=\frac{22}{2}~(Divide~2~on~both~sides)\\\\x=11~(Simplify)$

If observed frequencies are 5,10,15 and expected frequencies are each equal to 10 then chi square value is

lina2011 [118]

Answer:

Step-by-step explanation:

Given :

Observed values = 5, 10, 15

Expected freqencies = 10

χ² = Σ(observed - Expected)² / Expected

χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10

χ² = 25/10 + 0/10 + 25/10

χ² = 2.5 + 0 + 2.5

χ² = 5
