The probability of selecting a yellow and then a yellow without replacement is 3/10.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of red marbles = 1

Number of green marbles = 1

Number of yellow marbles = 3

Total number of marbles = 5

The probability of selecting a yellow and then a yellow without replacement.

= 3/5 x 2/4

= 6/20

= 3/10

We are using 2/4 since yellow marbles become 2 and the total marbles become 4 when the condition of without replacement is given.

Thus,

The required probability is 3/10.

The formula is also used to ensure that the patient is not overdosed or underdosed ,24.1 kg of body weight, 723 mg of cephalexin should be administered per day.

The conversion from 24.1 kg of body weight to milligrams (mg) of cephalexin administered per day can be calculated using the following formula:

Dose (mg) = Desired dose (mg/kg) x Body Weight (kg).

In this case, the Desired dose is 30 mg/kg. So, to calculate the total dose of cephalexin per day:

Dose (mg) = 30 mg/kg x 24.1 kg

Dose (mg) = 723 mg/day

Thus, for 24.1 kg of body weight, 723 mg of cephalexin should be administered per day.

The formula used in this calculation is a standard formula used to calculate the dose of medication to be administered to a patient based on their body weight. The formula is used to ensure that the patient receives the appropriate dosage of medication and that the medication is safe and effective.

The circumference of the circle with the diagram of 2.25 cm is 14.13 cm.

The circumference, also known as the length of a circle, is its circumference. By using the radius or diameter, we can calculate the circumference of a circle.

An irregular plane figure is a circle. Every point on the circle is equally distant from the circle's fixed centre. It has a radius of 1, making it a 2D shape. The Latin word "circulus," which means "small ring," is the source of the English word "circle."

Given that the diameter of the circle is 4.50 cm. The circumference of the circle is calculated as:-

C = 2πr

C = 2 x π x 2.25

C = 14.13 cm

It will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

Now, According to the question:

"Information available from the question"

A physicist measures the remaining radioactivity in a sample.

She finds that it reduces by 18% each year.

If there was 1.52 g of radioactive material left after 4 years.

In order to find the initial quality of radioactive material, we will use the formula:

Initial Quality = Final Quantity * (1 - Reduction Rate)^Years

We know that -

The final Quantity is 1.52 g, the reduction rate is 18% (or 0.18), and the number of years is 4.

Initial Quantity = 1.52 g × [tex](1-0.18)^4[/tex]

Initial Quantity = 1.52 g × 0.452

Initial Quantity = 0.68 g

Hence, the initial quantity of the radioactive material is 0.68 g.

b. In order to find how many more years it will take for the amount of radioactive material to reduce to 0.2 g, we will use the formula:

Years = log(Final Quality / Initial Quality) / log(1 - Reduction Rate)

We know that -

the final quality is 0.2 g, the initial quality is 0.68 g, and the reduction rate is 18% (or 0.18).

Years = log(0.2 / 0.0.68) / log(1 - 0.18)

Years = 7.15

Therefore, it will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

The linear demand equation: x = m(p) + b, where x is the number of occupied units, p is the monthly rent, and m and b are constants and the linear demand equation in this case is:

x = -1.04p + 44.16

To find the linear equation, we need to determine the slope (m) and the y-intercept (b). Using the two points provided, we can write a system of equations:

When p = $780, x = 40 units

40 = m($780) + b

When p = $852, x = 36 units

36 = m($852) + b

Solving for m and b, we get:

m = -1.04 and b = 44.16

So, the linear demand equation is:

x = -1.04p + 44.16

the helix r(t) = cos(πt/2), sin (πt/2),t) intersects the sphere x^2 + y^2 + z^2 = 2 in two points.

the angle of intersection at each point: θ = cos⁻¹ (√2/√π²+4)

the angle of intersection at each point: α = cos⁻¹(-√2 /(√π² +4))

Scientists in the fields of physics, engineering, and biology all do research on helices, which are a significant topic in the theory of curves in differential geometry. Helix (or generic helix) is defined as tangent vector field in 3-dimensional Euclidean space establishing a fixed angle with the curve's direction. A curve for which the tangent forms a constant angle with a fixed line is referred to as a helix or coil.

helix: r(t) = < cos(πt/2), sin(πt/2), t >    sphere: x² + y² + z² = 2

put it in the sphere's equation we get:

next, {cos(πt/2)}² + {sin(πt/2)}² + t² = 2

or, 1 + t² = 2

or, t² = 1

or, t = ± 1

thus, points of intersection r(1) = < cos(π/2), sin(π/2), 1 > = < 0, 1, 1 >

r(-1) = < cos(-π/2), sin(-π/2), -1 > = < 0, -1, -1 >

Step-by-step explanation: The figure is broken down, so let's find the area of the rectangle first. We are given 4 in and 2.3 in, which can be multiplied to get 9.2 in. Now, we need to find the area of the two triangles, but let's start with the one to the left. The area of a triangle is b x h x 1/2. 2.3 in x 2.5 in is 5.75 in, but we need to multiply that by 1/2 which is 2.875 in. Finally, we can find the area of the bottom triangle by using the same formula. 3 in x 2.9 in is 8.7 in, but we need to multiply it by 1/2, which is 4.35 in. Now, all we need to do is add all the areas we found together to get the total area of the figure. 9.2 in + 2.875 in + 4.35 in is 16.425 in^2, which means that option A is your answer.

A linear function would better approximate the data.

A linear function would better approximate the data described. This is because a linear function has a constant rate of change, while an exponential function has a changing rate of change. For example, if we take the data from 10 K to 15 K, we can calculate the rate of change for each 1 K increase in temperature. The rate of change of volume for a 1 K increase in temperature is calculated by taking the difference between the volumes at the two temperatures and dividing by the difference in the temperatures. With the given data, this would yield a rate of change of 0.7 cm3/K, 0.38 cm3/K, 0.92 cm3/K, 1.4 cm3/K, and 1.6 cm3/K. As we can see, the rate of change does not remain constant, but increases over the temperature range, indicating a nonlinear relationship. Therefore, a linear function would better approximate the data.
