A nurse prescribes a patient 73 mL of Tylenol3 every 6 hours. Tylenol3 has 17 milligrams of codeine for every 30 mL of Tylenol3. How much Codeine is Ken being prescribed per day?

Answers

Answer 1

The amount of codeine that Ken is being prescribed every day, given the Tyelenol 3 being prescribed is 165. 47 milligrams of Codeine

How to find the amount prescribed ?

The amount of codeine in 30 ml of Tylenol 3 is:

= ( 17 x 73 ) / 30

= 41. 37 mL of Codeine

The number of 6 hour periods in a day is:

= 24 / 6

= 4

The amount of codeine that Ken is being prescribed a day is therefore:

= 4 x 41. 37

= 165. 47 milligrams of Codeine

|3y - 7| - 10 = -5 solve for y:

Answers

Answer: y=1.25

Step-by-step explanation:

First things first you have to find what is in the bracket things (i don’t know what it’s called) So 3 - 7 is -4y but since it’s absolute it’s going to be 4y.

So now you’ve got 4y - 10 = -5. Your going to want to eliminate 10 so, subtract 10 to both sides giving you 4y = -5

Lastly to get y by itself you need to divide it by its self so, 4y divided by 4. Do it to both sides. This gives you…

Answers

The brain cancer with code is secondary malignant neoplasm of brain. So the option 3 is correct.

Some women experience persistent nerve pain (neuropathic pain) in the arm, armpit, or chest wall following breast cancer surgery. Due to the fact that it was originally identified in women who had mastectomies, this is known as post-mastectomy pain syndrome (PMPS), but it can also occur following other forms of breast-conserving surgery.

According to studies, 20% to 30% of women experience PMS symptoms following surgery. It most frequently occurs following procedures that remove tissue from the underarm or upper outer region of the breast.

It is crucial to discuss any pain you are experiencing with your doctor. You might not use your arm as you should because of PMPS, and eventually you might stop being able to use it normally.

A cross between a plant with flowers and a plant with white flowers yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plant? Explain

Answers

The genotype must be Rr and rr because the outcome is close to the 1:1 ratio of red to white flowering plants.

What is meant by Law of Dominance?

According to Mendel's law of dominance, one feature in a heterozygote will mask the existence of another trait for the same attribute. The dominant allele will be exclusively expressed, as opposed to both alleles contributing to a trait.

When parents with distinct, opposing qualities are crossed, only one form of the trait manifests itself in the offspring, according to Mendel's law of dominance. Only the dominant phenotypic characteristic will be present in the hybrid offspring. The first law of inheritance is the dominance principle.

This regulation states that the first generation of offspring from purebred parents shall exhibit solely dominant features.

There will be a 1:1 ratio between the dominant and recessive traits when a heterozygous dominant parent mates with a pure recessive parent.

The cross:

           r            r

R         Rr          Rr

r          rr           rr

The genotype must be Rr and rr since the outcome is close to the ratio of red to white flowering plants.

Therefore, the correct answer is option A. The result is close to the 1:1 ratio of red to white flowering plants, so the genotype must be Rr and rr.

The complete question is:

A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain

A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the Rr and ir

B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the genotype of each parent is Rr. The number of offspring was not large enough to produce the expected results

C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.

D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.

The point of intersection will be the x, and y coordinates where the two lines cross.

To determine the point(s) of intersection algebraically, we need to find the solutions of the system of equations:

y = x² - x + 1

We can re-arrange the equation to solve for x:

x² - x + 1 - y = 0

We can then use the quadratic formula to find the solutions:

x = (1 ± √(1 - 4(1)(-y)))/2

x = (1 ± √(1 + 4y))/2

Now we can substitute values for y to find the x-coordinates of the points of intersection.

Answers

If three bulbs are randomly selected, the probability that a) exactly 2 are 23 watts is 0.136, the probability that b) all are of the same type is 0.542 and c) there will be one bulb of each type is 0.244.

Here we have been given that out of 23 bulbs,

8 are 13 watt

9 are 18 watt

6 are 23 watt

now if three bulbs are randomly selected out of these, it can be done in

²³C₃ ways

a)

There are 6, 23 watts, and 17 bulbs that are not 23 watts.

Hence they can be chosen in

⁶C₂ X ¹⁷C₁ ways

Therefore the probability to get exactly 2 23 watt bulbs is

[⁶C₂ X ¹⁷C₁]/²³C₃

= [6 X 5 X 17 X 3 X 2]/[2 X 23 X 22 X 21]

= [3 X 5 X 17]/[23 X 11 X 7]

= 240/1771

= 0.136

b)

The probability that all three bulbs are of the same type will have three cases. Hence they can be selected in

⁸C₃ + ⁹C₃ + ⁶C₃ ways

Hence the probability will be

[⁸C₃ + ⁹C₃ + ⁶C₃]/²³C₃

= [(8 X 7 X 6) + (9 X 8 X 7) + (6 X 5 X 4)](3 X 2)/[23 X 22 X 21]

=  [(8 X 7 X 6) + (9 X 8 X 7) + (6 X 5 X 4)]/[23 X 11 X 7]

= [336 + 504 + 120]/1771

= 960/1771

= 0.542

c)

The probability to select one bulb of each type will be

[8 X 9 X 6]/²³C₃

= [8 X 9 X 6]/[23 X 11 X 7]

= 432/1771

= 0.244

d) Now if at least 6 bulbs need to be examined, hence

the probability will be 1 - probability that we need to check (1, 2, 3, 4, 5)

= 1 - (¹⁷C₀/23 + ¹⁷C₁/²³C₂ + ¹⁷C₂/²³C₃ + ¹⁷C₃/²³C₄ + ¹⁷C₄/²³C₅)

What is cube ?

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross. The cube is the only regular hexahedron and is one of the five Platonic solids.

The original surface area is (3x3) x 6 = 54 units.

A unit cube has 6 units of area, so we need 9 cubes.

Remove all the cubes except the original eight corners and the center cube.

The 3×3×3 cube has a surface area of 6×3×3 square units. Taking the 27 smaller units and connecting them to form a single entity, the maximum exposed surface area per cube is 6 square units. If nine of these are connected vertex to vertex in any shape then the objective is achieved. So a maximum of 18 of the small cubes can be removed.

Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.

The coordinates of the given image are :

(-1, 1), (-2, 1), (-1, 4) and (-2, 4).

Point of rotation is (-2, 1).

The points are not rotated around the origin.

To make it seem like around the origin, subtract the point of rotation from the points.

So the new points are :

(1, 0), (0, 0), (1, 3) and (0, 3)

Now rotate the image with the new coordinates around the origin 180° clockwise.

Rotation is -180°, which is equivalent to rotation of 180° counterclockwise.

Coordinates (x, y) when rotated 180° clockwise becomes (-x, -y).

New coordinates after rotation about origin are :

(-1, 0), (0, 0), (-1, -3) and (0, -3).

Now add the point of rotation (-2, 1) again.

If the applied force is F and the angle between the force and the displacement is θ, then the component of the force parallel to the displacement is Fcos(θ).

Therefore, the work done by the applied force is given by dFcos(θ). The force of friction will also do work, which is equal to the displacement of the block multiplied by the force of friction. The force of friction is given by μN, where N is the normal force and is equal to the weight of the block (mg).

Answers

The probability of a student completing the final examination in less than 65 minutes is 13.45%.

The time it takes to complete a final examination in a particular college course is normally distributed with a mean of 77 minutes and a standard deviation of 12 minutes. This can be expressed mathematically as X~N(77, 12).

The probability of a student completing the final examination in less than 65 minutes can be calculated by using the Z-score formula:

Z = (x - μ) / σ

Where x = 65 minutes, μ = 77 minutes, and σ = 12 minutes.

Plugging these values into the formula, we get:

Z = (65 - 77) / 12 = -1.17

Using a Z-score table, we can find the probability of a student completing the final examination in less than 65 minutes, which is equal to 0.1345, or 13.45%. Therefore, the probability of a student completing the final examination in less than 65 minutes is 13.45%.

The line segment is represented by a green line

To determine the average rate of change using the line segment; we have the following values.

When x = 5: y = 8

When x = 7: y = 0

So, the average rate of change (m) is:

m = Δy/Δx

Where:

Δy = y₂ - y₁

Δy = 0- 8

Δy = -8

Δx = x₂ - x₁

Δx = 7 -5

Δx = 2

So, we have:

m = Δy/Δx

m = -8/2

m = -4

Hence, the average rate of change from  x = 5 to x = 7  is -4

Complete question:

ch 7- a student investigating study habits asks a simple random sample of 16 students at her (large) high school how many minutes they spent on their english homework the previous night. suppose the actual parameter values for this variable are m=45 minutes and sd=25 minutes. which of the following best describes what we know about the sampling distribution of means for the student's sample?

Answers

The standard deviation of the sampling distribution of the mean is d)3.75; the distribution is approximately Normal.

According to the Central Limit Theorem, when the sample size is large enough (typically n > 30), the sampling distribution of the mean will be approximately normal, regardless of the shape of the population distribution.

In this case, the sample size is 16, which is larger than 30, so we can assume that the sampling distribution of the mean is approximately normal.

The standard deviation of the sampling distribution of the mean (also known as the standard error) is given by:

σm = σ/ √n

where σ is the population standard deviation and n is the sample size.

Plugging in the given values:

σm = 15/ √16 = 15/4 = 3.75

So the standard deviation of the sampling distribution of the mean for the student's sample is 3.75 minutes.

What is fraction?

A fraction is a mathematical expression that represents a part of a whole. It is expressed as two numbers separated by a line or a slash, with the number on top called the numerator and the number on the bottom called the denominator. The numerator represents the number of parts being considered, while the denominator represents the total number of parts in the whole. Fractions can be used to represent quantities such as lengths, distances, time, weight, and many other things in the real world. They are an important concept in mathematics and are used in a wide range of applications, from basic arithmetic to advanced calculus and beyond.

Here,

Let's denote the starting value of the house by x.

After the first year, the value increased by 9%, so the value became 1.09x.

After the second year, the new value decreased by 4%, so the value became 0.96(1.09x) = 1.0464x.

We know that this final value is £758,640, so we can set up an equation and solve for x:

1.0464x = 758640

x = 758640 / 1.0464

x ≈ 724492.37

What does the mathematical term "function" mean?

A function is a link or expression that contains one or more variables. There is a collection of inputs and outputs.

A function is a relationship between a number of inputs and outputs. Simply described, a function is an association between inputs in which each input is coupled to exactly one output. There is a range, codomain, and domain for every function. A function is typically referred to as f(x), where x is the input.

Applications of functions include population, distance traveled, and discovering profit. When using functions, one enters a number into the formula or locates the independent variable on a table or graph before computing the dependent variable that results.

(i) f(x²) = 2*x²

(ii) f(1) = 2*1 = 2

So, f(x²) = 2*x² and f(1) = 2
