Step-by-step explanation:

The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).

We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:

Radius of the circular feild = 27.5

circumference of the circular feild = 2 × 27.5 feet × 3.14

circumference of the circular feild = 55 feet × 3.14

circumference of the circular feild = 172.7 feet.

Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Answer:  \(8\sqrt{2}\)

==========================================================

Work Shown:

Focus entirely on triangle ABD (or on triangle BCD; both are identical)

The two legs of this triangle are AB = 8 and AD = 8. The hypotenuse is unknown, so we'll say BD = x.

Apply the pythagorean theorem.

\(a^2 + b^2 = c^2\\\\c = \sqrt{a^2 + b^2}\\\\x = \sqrt{8^2 + 8^2}\\\\x = \sqrt{2*8^2}\\\\x = \sqrt{8^2*2}\\\\x = \sqrt{8^2}*\sqrt{2}\\\\x = 8\sqrt{2}\\\\\)

So that's why the diagonal BD is exactly \(8\sqrt{2}\\\\\) units long

Answer:

the number has 2 resumable 6+5

Answer: The probability that both events A and B will occur is 5/18 or 0.28.

Step-by-step explanation:

To determine the probability that both events A and B will occur, we need to calculate the probabilities of each event separately and then multiply them together.

Event A: The probability of rolling a 5 or 6 on the first die is 2 out of 6 (since there are two favorable outcomes out of six possible outcomes on a fair six-sided die). Therefore, the probability of event A is 2/6 or 1/3.

Event B: The probability of not rolling a 1 on the second die is 5 out of 6 (since there are five favorable outcomes out of six possible outcomes). Therefore, the probability of event B is 5/6.

To find the probability that both events A and B occur, we multiply the probabilities:

Probability(A and B) = Probability(A) * Probability(B) = (1/3) * (5/6) = 5/18.

Required correct options are having cereal for breakfast more often is associated with having more bowls to wash, owning more chickens is associated with having more eggs, none of them respectively.

The relationship that most likely reflects correlation but not causation is "Having cereal for breakfast more often is associated with having more bowls to wash." There is a correlation between eating cereal for breakfast and having more bowls to wash, but eating cereal does not cause the increase in dirty dishes.

The relationship that most likely reflects both correlation and causation is "Owning more chickens is associated with having more eggs." There is a clear causal relationship between owning chickens and having more eggs, as the chickens lay the eggs.

The relationships that are left are:

Frying eggs more often is associated with cooking bacon more often.

Owning more goats is associated with owning more sheep.

Owning more horses is associated with having a larger stable.

Eating hot dogs more often is associated with eating coleslaw more often.

Eating sandwiches more often is associated with eating bread more often.

Eating burgers more often is associated with eating french fries more often.

None of these relationships can be definitively classified as reflecting only correlation or both correlation and causation without additional information. However, some of them are more likely to reflect causation than others based on common sense and prior knowledge. For example, the relationship between frying eggs more often and cooking bacon more often is likely to reflect a causal relationship, as it makes sense that someone who frequently cooks eggs would also frequently cook bacon to go with them.

The lateral and total surface area of square pyramid is 128 and 96.

What exactly are squares?

A square is a two-dimensional planar shape with four equal sides and four 90-degree angles. The qualities of a rectangle are comparable to those of a square. As a result, a rectangle is only considered a square if all four of its sides have the same length.

The following are the most significant qualities of a square:

(side)² Equals square area

square perimeter=4*side

Now,

Given that side of squared base=6

Step-by-step explanation:

To find the percent of change from 12 inches to 36 inches, we can use the following formula:

percent change = (new value - old value) / old value x 100%

Using this formula, we can substitute the values:

percent change = (36 - 12) / 12 x 100%

percent change = 24 / 12 x 100%

percent change = 200%

Therefore, the percent of change from 12 inches to 36 inches is 200%. This means that the value increased by 200% or tripled in size.

Answer:

200%

Step-by-step explanation:

36 - 12 = 24 inches

So, it changes 24 inches

Percent of change 12 inches to 36 inches?

Answer:

  $142.32, profit on sale of the policy

Step-by-step explanation:

You want to know the expected value of a $280,000 life insurance policy sold for $270, if the probability the insured will live for the year is 0.999544.

The insurance company expects to have to pay the $280,000 death benefit for 0.000456 of the policies issued. That means their expected payout on any one policy is ...

  0.000456 × $280,000 = $127.68

The company gets a premium of $270 for the policy, so the expected value of the policy to the company is ...

  $270 -127.68 = $142.32

The expected value of the policy to the company is $142.32.

This represents its profit from sale of the policy.

__

Additional comment

Of course, the company has expenses related to the policy, perhaps including a commission to the agent selling it, and expenses related to handling claims. That is to say that not all of the difference between the premium and the average death benefit is actually profit. It is what might be called "contribution margin."

Answer: x = 3(-1 + i) or 3(-1 - i)

Step-by-step explanation:

To solve the problem, we'll use the information given to find the values of A and k in the equation T = 20 + Ae^(-kt), where T is the temperature in degrees Celsius at time t.

a. Finding the value of A:

We're given that the initial temperature of the tea was 70℃. Substituting this into the equation, we get:

70 = 20 + Ae^(0) (since e^0 = 1)

70 - 20 = A

A = 50

So the value of A is 50.

b. Finding the value of k:

We're told that it takes 4 minutes for the tea to decrease in temperature from 70℃ to 50℃. We can use this information to set up an equation and solve for k.

Substituting T = 70 and t = 4 into the equation, we have:

70 = 20 + 50e^(-4k)

Subtracting 20 from both sides:

50 = 50e^(-4k)

Dividing both sides by 50:

1 = e^(-4k)

Taking the natural logarithm (ln) of both sides:

ln(1) = ln(e^(-4k))

0 = -4k

Dividing both sides by -4:

0 = k

However, we need to check if this solution satisfies the condition for the tea to decrease in temperature from 70℃ to 50℃ in 4 minutes.

Substituting T = 50 and t = 4 into the equation, we have:

50 = 20 + 50e^(-4(0))

50 = 20 + 50e^0

50 = 20 + 50(1)

50 = 20 + 50

50 = 70

Since 50 is not equal to 70, the value of k = 0 does not satisfy the given condition.

Let's try another approach:

Substituting T = 50 and t = 4 into the equation, we have:

50 = 20 + 50e^(-4k)

Subtracting 20 from both sides:

30 = 50e^(-4k)

Dividing both sides by 50:

0.6 = e^(-4k)

Taking the natural logarithm (ln) of both sides:

ln(0.6) = ln(e^(-4k))

ln(0.6) = -4k ln(e)

ln(0.6) = -4k(1)

ln(0.6) = -4k

Simplifying further:

k = ln(0.6) / -4

Using a calculator or computer to evaluate ln(3/5) / -4, we get approximately:

k = ln(5/3) / 4

To recap:

a. The value of A is 50.

b. The value of k is approximately k = ln(5/3) / 4

.

The vertical displacement is of 2 units down, the correct option is B.

Remember that for a function f(x), a vertical displacement of N units is written in general form as:

g(x) = f(x) + N

If N > 0, the translation is upwards.

if N < 0, the translation is downwards.

Here we assume that we start with the parent cosine function:

y = cos(x)

And the transformed function is:

y = -2 - cos(x - π)
