the healthcare provider prescribes propofol (diprivan) at 8 mcg/kg/minute for a client during conscious sedation. the drug is dispensed as a econdary infusion labled, 0.9% normal saline 50 ml with propofol 100 mg/50 ml the client's weight is 198 pounds. the nurse should program the infusion pump to deliver how many ml/hour? (enter numeric value only. if rounding is required, round to the nearest tenth.)
Answers
The nurse should program the infusion pump to deliver 21.6ml/hour
Given the following:
Drug propofol prescribed is 8mcg/kg/min
Drug dispensed in 100mg in 50ml NS
Weight of patient is 198 pounds
Converting pounds in Kg:
198 pounds is (1 pound is 0.45Kg)
89.8 equivalent to 90Kg
Converting 8mcg/kg/min into mg/kg/min:
8mcg is 0.008mg so it becomes 0.008mg/kg/min
Patient weight is 90 kg , so required drug is:
90x0.008=0.72 mg/min
Now 50ml has 100mg, so 1ml has 2mg
We want to give 0.72mg, so if there is 2mg in 1 ml how much will be 0.72 mg for, by doing cross multiplication we get as below:
2mg in 1 ml
0.72=?
=0.72x1/2
=0.36ml
Now we have to give 0.36ml/min
Infusion pump has rate in ml/ hour, as 1 hour has 60 min, we multiply 0.36x60=21.6ml/hour
Hence, Infusion pump delivered 21.6ml/hour

The equation of a line is y=4/3x + 4 . Is the point (6, 13) on the line? [ Select ] Is the point (9, 16) on the line?
Answers
The point (9, 16) is on the line.
Given,
The equation of the line = y = 4/3x + 4
We have to find whether the given points are on this line or not.
For that substitute the points into the equation.
That is,
Point (6, 13)
x = 6 and y = 13
Equation;
y = 4/3x + 4
13 = 4/3 x 6 + 4
13 = 8 + 4
13 ≠ 12
That is, the point (6, 13) is not in the line.
Next,
Point (9, 16)
x = 9 and y = 16
Equation;
y = 4/3x + 4
16 = 4/3 x 9 + 4
16 = 12 + 4
16 = 16
Therefore, the point (9, 16) is in the line.

How to solve linear equations on a graph?We graph both equations in the same coordinate system in order to visually solve a system of linear equations. The intersection of the two lines is where the system's answer will be found. The point where the two lines join is (-3, -4), which is where this equation system's solution lies.
There are 3 methods for graphing a linear equation:
1.displaying the graph of a linear equation using two points.
2.Use a linear equation's slope and y-intercept.

Answers

It'll take Jake 40 minutes to type the 1,000 word paper.
Explanation
Working at that same speed, let the number of minutes it will take Jake to type 1,000 word paper be x minutes.
25 words = 1 minute
1,000 words = x minutes
We can write a mathematical relationship for this by cross mutiplying
(25) (x) = (1,000) (1)
25x = 1,000
Divide both sides by 25
(25x/25) = (1,000/25)

Tommy deposited $2,000 into a savings account that earns 5% interest per year. What
equation would be used to determine how much money Tommy has after x number of years?
Answers
Answer:
7A, 8D
Step-by-step explanation:
The compound interest formula is as followed
[tex]A = P(1+\frac{r}{n} )^{nt}\\[/tex]
A = accumulated amount
P = principle
r = interest rate
n = compounding
t = time
The accumulated amount is represented by f(x).
The principle is the amount of money you start with. In this case Tommy starts with 2000 dollars. P = 2000
The interest rate is 5%. This needs to be converted into a decimal.
5% = 0.05 = r
The money is compounded annually, thus n = 1.
The time is represented by x. x = t.
thus
[tex]f(x) = 2000(1+0.05)^{x}[/tex]
After six years, you simply find f(6), or substitute 6 into x.
f(6) = 2000(1.05)^6 = $2,680.19

In a school of 2000 students, the ratio of teachers to students is 3:80.
Some teachers join the school and the ratio changes to 1:20.
Find the number of teachers who joined the school.
Answers
25 new teachers joined the school such that the new ratio is 1 : 20 .
In mathematics, a ratio illustrates how frequently one number appears in another. For instance, the ratio of oranges to lemons on a fruit platter would be eight to six if there were eight oranges and six lemons.
Ratios can be decreased by dividing each quantity by the sum of all the common components of the numbers (much like fractions are). When the ratio's numbers are the smallest practical integers, the fraction is said to be in its simplest form.The ratio's antecedent and consequent are frequently referred to as A and B, respectively.The total number of students is 2000
The ratio of teachers to students is 3:80 .
Therefore the number of teachers = 3 × 2000 ÷ 80 = 75
Let x teachers joined the school.
Therefore new ratio = (x+75) : 2000
but the new ratio is 1 : 20
Therefore 1 : 20 = (x+75) : 2000
Simplifying we get:
x + 75 = 100
or, x = 25
Therefore the number of teachers who joined the school is 25 .

Answers
The elevation at which the diver takes the picture is -14 3/4 feet if, on a cave dive in Oahu, a scuba diver swims at an elevation of 20 3/4 ft relative to sea level.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
On a cave dive in Oahu, a scuba diver swims at an elevation of 20 3/4 ft relative to sea level.
Let x be the elevation at which the diver takes the picture.
The value of x can be found as follows:
x = -20 3/4 + 6
x = -83/4 + 6
x = (-83 + 24)/6
x = -59/6

What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. Equations are used to describe geometric shapes in Cartesian geometry. Because the equations under consideration, such as implicit equations or parametric equations, contain an unlimited number of solutions, the goal has shifted: instead of directly stating the solutions or counting them, which is impossible, one utilizes equations to investigate the features of figures. This is the fundamental concept of algebraic geometry, a significant branch of mathematics. An equation consists of two expressions joined by an equals sign ("="). The expressions on each side of the equals sign are referred to as the equation's "left-hand side" and "right-hand side."
The equation of the line is given below:
y - 3 = -5(x - 4)
or, y - 3 = -5x - 20
or, 5x + y + 17 = 0
Hence, the required equation of the line is 5x + y + 17 = 0.

Answers
The z-value for 29 and 34 hours is z(32) = 0, the garages take between 32 hours and 34 hours to erect 34%, the garages take between 29 hours and 34 hours to erect 77.45%, and the garages, 5% take 35.29 hours of time.
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
Weston Materials, Inc., a national manufacturer of detached garages, states that erecting the Red Barn type takes two construction workers a mean of 32 hours and a standard variation of 2 hours. Assume that the assembly times are distributed normally.
Calculating the z values for 29 and 34 hours.
z(29) = (29-32)/2 = -3/2
z(34) = (34-32)/2 = 1
z(32) = 0
The percentage of garages take between 32 hours and 34 hours to erect as:
⇒ P(32 < x < 34) = P(0< z < 1) = 0.34
The percentage of garages take between 29 hours and 34 hours to erect as:
⇒ P(29 < x < 34) = P(-1.5 < z < 1) = 0.7745
The percentage of garages take 28.7 hours to erect as:
⇒ z(28.7) = (28.7-32)/2 = -3.3
⇒ P(0 < x < 28.7) = P (-10 < z < -3.3) = 0.00048348...
The z-value corresponds to a 95% left area and only
5% to the right under the curve.
Use z-chart or InvNor(0.95) = 1.645

suppose babies born in a large hospital have a mean weight of 3316 grams, and a standard deviation of 324 grams. if 83 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by less than 54 grams? round your answer to four decimal places.
Answers
The probability that the mean weight of the sample babies would differ from the population mean by less than 54 grams is 0.4339.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 3316 grams - 54 grams = 3262
μ = mean = 3316 grams
σ = standard deviation = 324 grams
z-score = (3262 - 3316) / 324
z-score = -54 / 324
z-score = -0.1667
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = -0.1667
