The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of DşW at 25 drops/minute. The nurse uses an infusion set that delivers 15 gtt/mL and starts the infusion at 1900. Using the 24-hour clock, what time should the nurse anticipate the infusion to be completed? (Enter numeric value only.)
The infusion will be completed at 19:31
The medicine that the nurse is giving the patient is 1 gram of ampicillin diluted in 50 mL of dextrose water.
This means 50 mL + 1 mL = 51 mL. 1 gram of ampicillin = 1 mL considering all water-based substances have a density of 1gm/mL.
Now, the set delivers 15 ggt or drops per mililiter. Let's calculate the total drops in the 51 mL.
51mL x 15ggt =765 drops
Finally, we know the medicine is given at a rate of 25 drops per minute. Let's calculate the time:
765 drops / 25 drops per minute = 30.6 minutesThis means the medicine it will take 30.6 minutes for the infusion to be completed and therefore the infusion will be completed at 19:31 (19:00 + 30.6 minutes = 19:30.6 or 19:31).

y = 1/2 x - 1
y = 1x - 1/2
y = -1/2 x + 1
y = -x + 1/2

1. In a science lab, you collect the following sets of data. Which of the
four data sets are linear functions? If linear, determine the slope.
Answer:
data set: a ; slope: 1/2
Step-by-step explanation:
If an equation is linear, then the first common differences are all the same.
In table a:
17-12 = 5
22-17 = 5
27-22 = 5
etc.
Equation:
m represents slope
y = mx + b
y = mx + 12 (y-intercept is 12)
17 = 10m + 12
10m = 17-12
10m = 5
m = 10/5 = 1/2

A survey is conducted to collect information about tour preference. 100 interviewees are asked to choose
from ‘River Cruise’, ‘Shopping tour’ or ‘Eco Trip’ as the main activity for the last day of a tour. Below is
the result of the survey:
Male Female
River Cruise 20 , 14
Shopping Tour 15 , 36
Eco Trip 11 , 4
(a) Find the probability that an interviewee chooses ‘Eco Trip’.
(b) Find the probability that a male interviewee chooses ’Shopping Tour’.
(c) In the group of interviewees choosing ‘Shopping Tour’, find the proportion of female.
(d) An interviewee does not choose “River Cruise”. What is the probability that this person is a female?
(e) May is one of the female interviewees in this survey. She does not choose “Eco Trip”. What is the
probability that she chooses “River Cruise”?
Using the probability concept, it is found that:
a) There is a 0.1485 = 14.85% probability that an interviewee chooses ‘Eco Trip’.
b) There is a 0.3261 = 32.61% probability that a male interviewee chooses ’Shopping Tour’.
c) The proportion of females is of 0.7059 = 70.59%.
d) There is a 0.6061 = 60.61% probability that this person is a female.
e) There is a 0.3953 = 39.53% probability that she chooses “River Cruise”.
A probability is the number of desired outcomes divided by the number of total outcomes.
Item a:
Total of 20 + 14 + 15 + 36 + 11 + 5 = 101 interviewees.11 + 4 = 15 choose Eco Trip.Hence:
[tex]p = \frac{15}{101} = 0.1485[/tex]
0.1485 = 14.85% probability that an interviewee chooses ‘Eco Trip’.
Item b:
20 + 15 + 11 = 46 male interviewees, 15 choose Shopping Tour, hence:
[tex]p = \frac{15}{46} = 0.3261[/tex]
0.3261 = 32.61% probability that a male interviewee chooses ’Shopping Tour’.
Item c:
15 + 36 = 51 interviewees choose Shopping Tour, 36 are female, hence:
[tex]p = \frac{36}{51} = 0.7059[/tex]
The proportion of females is of 0.7059 = 70.59%.
Item d:
15 + 36 + 11 + 4 = 66 interviewees do not choose River Cruise, 36 + 4 = 40 are female, hence:
[tex]p = \frac{40}{66} = 0.6061[/tex]
0.6061 = 60.61% probability that this person is a female.
Item e:
101 - 15 = 86 people do not choose Eco Trip, of those, 34 choose River Cruise, hence:
[tex]p = \frac{34}{86} = 0.3953[/tex]
0.3953 = 39.53% probability that she chooses “River Cruise”.

1. When a ball was kicked off the ground it landed 20 feet horizontally and reached a maximum height of 6 feet. Create a sketch of the ball's flight and find an equation that describes it.
2. Find the equation of a square foot function with a vertex at (-5, 4) and that passes through the (20, 29).
3. Write the following in graphing form: y = x^2 - 18x + 5

Answer:
y = 0.06x(20 -x)y = 5√(x+5) +4y = (x -9)^2 -76; (9, -76); 9±√76; 5Step-by-step explanation:
1.If we assume the ball was kicked from the origin and that it follows a parabolic curve, the equation can be written ...
y = -kx(x -20)
for some value of k that makes the maximum be 6. The maximum will occur at the value of x that is halfway between the points where the ball is on the ground, so at x=10. Then our value of k is such that ...
6 = k(10)(20 -10) = 100k
k = 6/100 = 0.06
The equation describing the ball's flight is ...
y = 0.06x(20 -x)
A graph is attached.
__
2.The translated square root function will have a vertical multiplier k that will make it pass through the given point. The parent function f(x) = √x can be translated so its vertex moves from (0, 0) to (-5, 4) by ...
g(x) = 4 +f(x+5)
Applying the scale factor k gives ...
g(x) = k·√(x +5) +4
We want g(20) = 29, so ...
29 = k·√(20 +5) +4
25 = 5k . . . . subtract 4
5 = k . . . . . . divide by 5
The equation of the function is ...
y = 5√(x +5) +4
__
3.We assume your "graphing form" is "vertex form", as that form is generally conducive to graphing.
We can complete the square by adding and subtracting the square of half the x-coefficient:
y = x^2 -18x +9^2 +5 -9^2
y = (x -9)^2 -76 . . . . . equation
vertex: (9, -76)
x-intercepts: 9±√76 ≈ {0.2822, 17.1778}
y-intercept: 5 . . . . (the constant in the given equation)
_____
Additional comment
When the quadratic is written in vertex form ...
y = a(x -h)^2 +k
the x-intercepts are h±√(-k/a).
