The pharmaceutical company uses the quantitative variable to conducts an experiment.

Variables:

A variable is a characteristic of an object. Their values may occur more than once for a set of data. We consider just two main types of variables in this course.

Quantitative Variables - Variables whose values result from counting or measuring something.

Qualitative Variables - Variables that are not measurement variables. Their values do not result from measuring or counting.

Given,

A pharmaceutical company conducts an experiment in which a subject takes 75 mg of a substance orally.

And  the researchers measure how many seconds it takes for one quarter of the substance to exit the bloodstream.

Here we need to find the kind of variable is the company​ studying.

Here the company uses the Qualitative Variable because here they measure the effects of the medicine not the measurement.

So, the experiment uses the Qualitative Variable.

From the figure we can see that,

< BAG + < BAC + < CAD = 180° (supplementary angles)

____________________

So to solve,

\( < BAG + < BAC + < CAD = 180 \\ 2x + 90 + x = 180 \\ 2x + x + 90 = 180 \\ 3x + 90 = 180 \\ 3x = 180 - 90 \\ 3x = 90 \\ x = \frac{90}{3} \\ x = 30\)

A complete graph is one in which there is an edge connecting every vertex to every other vertex. In order to determine for what values of n a complete graph with n vertices has an Euler circuit and a Hamiltonian circuit, let's discuss the definitions and requirements of each type of circuit.

1. Euler Circuit: An Euler circuit is a path that traverses each edge of a graph exactly once and returns to its starting vertex. For a graph to have an Euler circuit, all vertices must have an even degree (number of edges connected to the vertex).

2. Hamiltonian Circuit: A Hamiltonian circuit is a path that visits every vertex in a graph exactly once and returns to its starting vertex. A complete graph always has a Hamiltonian circuit, regardless of the number of vertices.

Now, let's determine for what values of n a complete graph has an Euler circuit:

In a complete graph with n vertices, each vertex is connected to every other vertex, which means the degree of each vertex is (n-1). For a complete graph to have an Euler circuit, all vertices must have an even degree. This implies that (n-1) must be even, so n must be odd.

So, for a complete graph with n vertices to have an Euler circuit, n must be an odd number.

In summary:
- A complete graph with n vertices always has a Hamiltonian circuit.
- A complete graph with n vertices has an Euler circuit if n is an odd number.

Answer:

-10.4

Step-by-step explanation:

Assume that the number we are looking for is x.

Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x

step by step

half the number is 0.5x

the sum of half the number and 6 is 0.5x + 6

10 times the sum of half the number and 6 is 10(0.5x +6)

10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8

Now solve for x

10(0.5x + 6) = 8

5x + 60 = 8

5x = 8 - 60

5x = -52

x = -52/5

x = -10.4

-3z-(-z-2) can be simplified as follows:

Answer: The measurement of angle B is 50 degrees

Step-by-step explanation: we know all triangles add up to 180 degrees so substitute 40 with a degrees and solve

Step-by-step explanation:

According to the Triangle Sum Theorem, all angles in triangle are sum of 180⁰. This means that m<a + m<b + m<c = 180⁰. You will first solve for a.

m<a + m<b + m<c = 180⁰

2a⁰ + a + 10⁰ + a⁰ = 180⁰ combine like terms.

2a⁰ + a + a⁰ + 10⁰ = 180⁰

4a⁰ + 10⁰ = 180⁰ subtract 10 from both sides.

4a⁰ + 10⁰ - 10⁰ = 180⁰ - 10⁰

4a⁰ = 170⁰ Divide 4 from both sides.

4a⁰ / 4 = 170⁰ / 4

a = 42.5⁰

Now that you found a, plug 42.5⁰ in place of in all angles and solve.

m<a :-

2a⁰

2(42.5)⁰

85⁰

m<b :-

a + 10⁰

42.5⁰ + 10⁰

52.5⁰

m<c :-

a⁰

42.5⁰

m<a = 85⁰

m<b = 52.5⁰

m<c = 42.5⁰

Remember that all angle must sum up to 180⁰ in a triangle. So we will now add all of our angle to find it if it equals 180⁰.

m<a + m<b + m<c = 180⁰

85⁰ + 52.5⁰ + 42.5⁰ = 180⁰

180⁰ = 180⁰

Thus, m<b = 52.5⁰.

Answer:

Step-by-step explanation:

Well you basically divide 3 and 1/2 by 1/6 which you would you have to simplify the 3 and 1/2 which is 7/2 and switch the denominator and numerator of the 1/6 which would be 6/1 and after you multiply(7/2 x 6/1=42/2) it would be 42/2 which you would have to simplify by dividing 42 and 2 which is 21. There you go I hope this helps.

Answer:

21.

Step-by-step explanation:

That would be  3 1/2 divided by 1/6.

= 7/2 / 1/6

= 7/2 * 6

Radhika bought a house for Rs. 5,20,000 and spent Rs. 80,000 on repairs. She sold the house for Rs. 6,40,000.

To calculate her profit or loss percentage, we need to determine the overall gain or loss and express it as a percentage of the cost price.

To find the profit or loss percentage, we first need to calculate the total cost incurred by Radhika. This includes the purchase price of the house and the amount spent on repairs:

Total cost = Purchase price + Repair cost

Total cost = Rs. 5,20,000 + Rs. 80,000

Total cost = Rs. 6,00,000

Now, we can calculate the overall gain or loss by subtracting the total cost from the selling price:

Overall gain or loss = Selling price - Total cost

Overall gain or loss = Rs. 6,40,000 - Rs. 6,00,000

Overall gain or loss = Rs. 40,000

To find the profit or loss percentage, we divide the overall gain or loss by the total cost and multiply by 100:

Profit or loss percentage = (Overall gain or loss / Total cost) × 100

Profit or loss percentage = (Rs. 40,000 / Rs. 6,00,000) × 100

Profit or loss percentage ≈ 6.67%

Therefore, Radhika made a profit of approximately 6.67% on the sale of the house.

Answer:112

Step-by-step explanation: 1/4 divided by 28/1 = 1/112

Answer:

112 and very light

Step-by-step explanation:

In Step 3, Mike made an error. He incorrectly calculated his value for m by multiplying 2 by 22 instead of 2 by (22 + 4). The correct equation should have been m = 2(22 + 4).

Sally's formula for calculating b is correct:

b = 11

Sally's formula for calculating m is also correct:

m = 2(11) + 4 = 26

Mike's formula for calculating b is correct:

b = 22

However, Mike's formula for calculating m is incorrect. Instead of using the formula m = 2(b + 4), he used the formula m = 2(22 + 4), which gives him a value of 50 instead of the correct value of 50.

Therefore, Mike made a mistake in Step 3. He computed his answer for m erroneously by multiplying 2 by 22 rather than 2 by (22 + 4). The proper formula would have been m = 2(22 + 4).

The coordinates of the vertices are W(-2, 4), X(3, 1), Y(4, -4), and Z(-1, -3).

Using the distance formula,

\(WX=\sqrt{(-2-3)^{2}+(4-1)^{2}}=\sqrt{34}\\\\XY=\sqrt{(3-4)^{2}+(1-(-4))^{2}}=\sqrt{26}\\\\YZ=\sqrt{(4-(-1))^{2}+(-4-(-3))^{2}}=\sqrt{26}\\\\WZ=\sqrt{(-2-(-1))^{2}+(4-(-3))^{2}}=\sqrt{50}\)

Step-by-step explanation:

The solution to the system of equations is x = 2 and y = 0.

To solve the system of equations:

3x - 5y = 6 ...(1)

-3x - 8y = -6 ...(2)

We can use the method of elimination or substitution. Let's use the elimination method.

Step 1: Multiply equation (1) by 3 and equation (2) by 1 to create coefficients for x that will cancel each other out when added.

Multiply equation (1) by 3:

9x - 15y = 18 ...(3)

Multiply equation (2) by 3:

-9x - 24y = -18 ...(4)

Step 2: Add equations (3) and (4) together to eliminate the x variable.

(9x - 15y) + (-9x - 24y) = 18 + (-18)

-15y - 15y = 0

-39y = 0

Simplifying, we find that -39y equals 0.

Step 3: Solve for y.

Divide both sides of the equation by -39 to isolate y:

-39y / -39 = 0 / -39

y = 0

Step 4: Substitute the value of y back into either equation (1) or (2) to solve for x.

Let's substitute y = 0 into equation (1):

3x - 5(0) = 6

3x = 6

x = 6 / 3

x = 2

Therefore, the solution to the system of equations is x = 2 and y = 0.
