the rate of change of the radius at the instant the volume equals 36π cm³ is 7 / (36π) cm/sec.

The volume V of a sphere with radius r is given by the formula V = (4/3)πr³. We are given that the rate of change of the volume is 7 cm³/sec. Differentiating the volume formula with respect to time, we get dV/dt =(4/3)π(3r²)(dr/dt), where dr/dt represents the rate of change of the radius with respect to time.

We are looking for the rate of change of the radius, dr/dt, when the volume equals 36π cm³. Substituting the values into the equation, we have: 7 = (4/3)π(3r²)(dr/dt)

7 = 4πr²(dr/dt) To find dr/dt, we rearrange the equation: (dr/dt) = 7 / (4πr²) Now, we can substitute the volume V = 36π cm³ and solve for the radius r: 36π = (4/3)πr³

36 = (4/3)r³

27 = r³

r = 3  Substituting r = 3 into the equation for dr/dt, we get: (dr/dt) = 7 / (4π(3)²)

(dr/dt) = 7 / (4π(9))

(dr/dt) = 7 / (36π)

The probability that it is gold is (1/3).

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. If two events are mutually exclusive, then there is a 0 percent chance that they will both happen at the exact moment. Two events are said to be mutually exclusive if they share no elements (their intersection is the empty set). Consequently, P(A∩B)=0.

Let A be the event that a gold marble is picked.

Let B₁ and B₂ be the event that the first bag is chosen and the second bag is chosen respectively.

Given: P (B₁ ) = 2.P(B₂)

Also, P(B₁) + P(B₂) = 1

∴ 2P(B₂) + P(B₂) =1

3P(B₂) = 1

P(B₂) = 1/3 and  P(B₁) = 2/3

Now

P(A)

= P(A∩(B₁∪B₂))

= P[(A∩B₁)∪(A∩B₂)]

Probability adds up because the events are mutually exclusive

= P(A∩B₁) + P(A∩B₂)

= P(B₁). P(A/B₁) + P(B₂). P(A/B₂)

= (2/3)×(3/16) + (1/3)×(15/24)

= (1/3)

Answer:

\(g=\frac{\sqrt{7}}{2}+1\) or \(g=-\frac{\sqrt{7}}{2}+1\)

Step-by-step explanation:

\(4\left(g-1\right)^2+6=13\)

\(4\left(g-1\right)^2=13-6\)

\(4\left(g-1\right)^2=7\)

\(\left(g-1\right)^2=\frac{7}{4}\)

\(g-1 = \pm\sqrt{\frac{7}{4} }\)

\(g =\pm \sqrt{\frac{7}{4} }+1\)

Final answer:

\(g=\frac{\sqrt{7}}{2}+1\)  or  \(g=-\frac{\sqrt{7}}{2}+1\)

Answer:

Step-by-step explanation:

\(4(g-1)^{2} +6=13\)

First we expand the brackets:

\(4(g-1)(g-1)+6=13\)

\((4g-4)(g-1)+6=13\)

\(4g^{2} -4g-4g+4+6=13\)

\(4g^{2} -8g+10=13\)

Now make it into a quadratic in the form \(ax^{2} +bx+c=0\):

\(4g^{2} -8g -3=0\)

Now using the quadratic formula:

\(x=\frac{-b(+/-)\sqrt{b^{2}-4ac} }{2a}\)
We can solve for g:

\(g_{1}\) = \(\frac{2+\sqrt{7} }{2}\)        
\(g_{2}\)  = \(\frac{2-\sqrt{7} }{2}\)

Using the given formula, we can see that the probability is:

P(medium | hot)  = 0.74

To do it, we need to use the values in the table and the little formula that is below it:

P(B|A) = P(A ∩ B)/P(A)

We want to get the probability:

P(medium | hot)

First we need to get P(hot), there are 100 customers, and of these, 5 + 48 + 22 = 65 orders are hot, then the probability is:

P(hot) = 65/100 = 0.65

And the joint probability, there are 48 medium and hot orders, then:

P(medium ∩ hot) = 48/100 = 0.48

Now we can use the formula to get:

P(medium | hot) = 0.48/0.65 = 0.74

Step-by-step explanation:

Therefore, the annual annuity payment can be approximately $6,069,727.

To calculate the size of the annual annuity payment, we can use the present value formula for an ordinary annuity. The formula is given by:

PMT = PV / [(1 - (1 + r)⁻ⁿ) / r]

Where:

PMT = Annual annuity payment

PV = Present value of the annuity

r = Annual interest rate

n = Number of periods

Given:

PV = $230 million

r = 8% = 0.08

n = 40 years

Using the formula, we can calculate the annual annuity payment:

PMT = 230,000,000 / [(1 - (1 + 0.08)⁻⁴⁰) / 0.08]

PMT ≈ $6,069,727

A completely randomized experimental design and a randomized block design are two types of experimental designs used in research.

In a completely randomized design, subjects or experimental units are randomly assigned to different treatment groups.

Each subject has an equal chance of being assigned to any treatment group, and there is no consideration for any potential blocking factors.

This design is often used when there are no known sources of variability or potential confounding factors that need to be controlled.

On the other hand, a randomized block design involves grouping subjects or experimental units into blocks based on a certain characteristic or blocking factor that may influence the outcome.

Within each block, subjects are randomly assigned to different treatment groups.

This design allows for better control of potential confounding variables, as it ensures that each treatment group is represented equally within each block.

Overall, the main difference between a completely randomized design and a randomized block design lies in the consideration of blocking factors.

Completely randomized designs are simpler and more straightforward, while randomized block designs are more effective at controlling for potential confounding variables.

Step-by-step explanation:

Answer:

1) 12 boxes

2) 3, 6, 12

3) 12

4) 110 degrees

Step-by-step explanation:

1) Count the rectangles. Multiply the length of the rectangle in boxes to the width of rectangle in boxes.

Length: 4 boxes

Width: 3 boxes

4 x 3 = 12

12 boxes

2)

10% of 30 is 0.1 times 30.

0.1 x 30 = 30/10 = 3

20% of 30 is 0.2 times 20.

0.2 x 30 = 30/5 = 6

40% of 30 is 0.4 times 20.

0.4 x 30 = 30/2.5 = 12

3) Count the cubes. Reminder there are 2 boxes you cannot see.

11 Sections

10 x 11 = 110

The answer is (D) The limit cannot be determined from the information given.

To start, we need to simplify the given equation:

f(2) = g(2) + h(2)

Substituting 2 into g(x), we get:

g(2) = sin(2π/3 + 2) + 3

Using the unit circle, we can see that sin(2π/3 + 2) = sin(2π/3 - 1) = √3/2 * cos(1) - 1/2 * sin(1)

So, g(2) = √3/2 * cos(1) - 1/2 * sin(1) + 3

Now, substituting 2 into h(z), we get:

h(2) = -2/(2+3)

Simplifying, we get h(2) = -2/5

Therefore, f(2) = g(2) + h(2) = √3/2 * cos(1) - 1/2 * sin(1) + 3 - 2/5

Now, to find the limit as x approaches 3, we need to evaluate:

lim (x→3) f(x)

However, since we only have information for f(2), we cannot determine the limit as x approaches 3.

Therefore, the answer is (D) The limit cannot be determined from the information given.

Step-by-step explanation:

tan = opposite/adjacent

The opposite of θ is 45 cm long

The adjacent of θ is 10 cm long

tan θ = 45 / 10 = 4.5

The solution is: the value of tan is : tan θ = 4.5.

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

here, we have,

The six trigonometric functions are sin , cos , tan , cosec , sec and cot
