5. While still in the hospital, the doctor writes an order for an antibiotic at 300mg/kg daily. You are nervous now because the nurse was wrong before. If you weigh 123 lb, determine how many milligrams you should be given.
The correct answer is 16737 mg
Explanation:
The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:
123 lb x 0.453 = 55.791 kg
Now, simply multiply the kilos by the recommended dose:
55.791 kg x 300 mg/kg = 16737 mg
Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)
16737mg ÷ 1000 = 16.737 grames

~Add 24 to both sides
15x = 6x + 63
~Subtract 6x to both sides
9x = 63
~Divide 9 to both sides

Which is the interquartile range for the city that has the greater variability in temperature?
Answer:
D. 40
Step-by-step explanation:
The greater the interquartile range of a data set, the greater the variability.
Interquartile range = third quarter (Q3) - first quartile (Q1)
Interquartile range of City A = 70 - 40 = 30
Interquartile range of City B = 80 - 40 = 40.
City B has a greater interquartile range than city A, therefore, City B has the greater variability in temperature, with an interquartile range of 40.
If an exterior angle of a regular polygon is 21.2º, how many sides does the polygon have?
Answer:
option 4. 17
Step-by-step explanation:
sum of angles = exterior angle x n
360° = 21.2° n
n = 360 / 21.2
n = 17
Number of sides of the regular polygon with exterior angle 21.2° is equals to 17 sides.
What is polygon?" Polygon is defined as the two dimensional geometric shape which has n number of finite sides."
Formula used
360° = (Exterior angle of polygon ) × ( number of sides of polygon)
According to the question,
Given,
Exterior angle of a regular polygon = 21.2º
'n' represents the number of sides
Substitute the value in the formula to get number of sides,
[tex]360\°= (21.2\°) (n)[/tex]
⇒ [tex]n = \frac{360\°}{21.2\°}[/tex]
⇒ [tex]n= 16.98[/tex]
⇒ n≈ 17 sides
Hence, number of sides of the regular polygon with exterior angle 21.2° is equals to 17 sides.

The constant in an algebraic expression is the number part of the expression for example.. IN 2x 2 is the constant it doesn't change and x is variable it may vary
solve for x 5x-2=3x+4
Answer:
3
Step-by-step explanation:
Simplifying
5x + -2 = 3x + 4
Reorder the terms:
-2 + 5x = 3x + 4
Reorder the terms:
-2 + 5x = 4 + 3x
Solving
-2 + 5x = 4 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-2 + 5x + -3x = 4 + 3x + -3x
Combine like terms: 5x + -3x = 2x
-2 + 2x = 4 + 3x + -3x
Combine like terms: 3x + -3x = 0
-2 + 2x = 4 + 0
-2 + 2x = 4
Add '2' to each side of the equation.
-2 + 2 + 2x = 4 + 2
Combine like terms: -2 + 2 = 0
0 + 2x = 4 + 2
2x = 4 + 2
Combine like terms: 4 + 2 = 6
2x = 6
Divide each side by '2'.
x = 3

A normal distribution has a mean of 186.4 and a standard deviation of 48.9. What percent of data will be greater than 235.3?
Answer:
15.9% of the data will be greater than 235.3.
Step-by-step explanation:
Use a calculator with statistical functions. In this case you'll need the cumulative normal distribution: normcdf(.
Evaluate the following: normcdf(235.3, 10000,186.4, 48.9):
We get: 0.159, or 15.9%
15.9% of the data will be greater than 235.3.
The range of value X > 284.2 of data will be greater than 235.3.
What is a z-score?A Z-Score is a statistical measurement of a score's relationship to the mean in a group of scores.
We know that the upper 2.5% of data would be 97.5% of data.
We will use a z-score formula to solve our given problem.
[tex]\rm z=\dfrac{x-\mu}{\sigma}[/tex]
Where; z = z-score,
x = Random sample score,
[tex]\mu[/tex] = Mean,
[tex]\sigma[/tex] = Standard deviation.
We will use a normal distribution table to find a z-score corresponding to 97.5% area or 0.975.
We can see from the normal distribution table that the z-score corresponding to the area of 0.975 is 1.96.
[tex]\rm 1.96=\dfrac{x-186.4}{48.9}\\\\1.96 \times 48.9 =x-186.4\\\\x = 186.4 +95.84\\\\x=282.84[/tex]
Hence, the range of value X > 284.2 of data will be greater than 235.3.

100 POINTSSSS!! I AM IN DESPERATE NEED OF HELP! so like help? i am struggling with the part where i make an equation for the blocks. i have a few more problems like this to do, so please give me a full explanation of how you solved it. thank you!!
Numbers 1 and 2 are correct.
Question 3:
We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.
Question 4:
[(2 + f) * (f)] + 2 = b
(2 + f) represents the number of blocks in each column.
(f) represents the number of blocks in each row.
2 represents the two extra blocks in each figure.
Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3
We can test our equation with figure three.
[(2 + f) * (f)] + 2 = b
We have figure three so f = 3. Substitute and solve.
[(2 + 3) * (3)] + 2 = b
[5 * 3] + 2 = b
15 + 2 = b
17 = b
In the example, the number of blocks is 17. Therefore, this equation works for any figure.
Best of Luck!
Answer:
We will see that the number of rows in each figure corresponds to the figure amount. Figure 1 has one row, figure 2 has two rows, figure 3 has three rows, and so on. Another thing we can see is that in each diagram, one block is attached to each column. We get 22 blocks for one column if we count from 3 and keep adding 1 for each column. There will be 20 rows and 22 columns in Figure 20. We must also remember that they add two additional blocks at the top and bottom that protrude like the ones shown. Figure 20 will have a limit of 442 blocks.
4th question:
[(2 + f) * (f)] [(2 + f) * (f)] [(2 + f) 2 + 1 = b
The number of blocks in each column is represented by (2 + f).
The number of blocks in each row is represented by (f).

Kukui (Hawaii): 9,293 millimeters and Melchior (Antartic Peninsula): 47 inches
Click the icon to view a table of English and Metric Equivalents.
Answer: Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.
Step-by-step explanation:
Given: The average rainfall amounts for two of the world's wettest places:
Kukui (Hawaii): 9,293 millimetres
Melchior (Antarctic Peninsula): 47 inches
Since 1 inch = 25.4 millimetres
∴ 47 inches = 47 × 25.4 millimetres
= 1193.8 millimetres
i.e. Melchior (Antarctic Peninsula) has 1193.8 millimetres of average rainfall.
Clearly, 9,293 millimetres> 1193.8 millimetres
So, Kukui (Hawaii) has the greater average rainfall .
Difference = 9293 - 1193.8 = 8099.2 millimetres
So Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.
