Answer:
circumference=2πr
=2×3.14×8.5
=53.38cm
Answer:
53.38 cm
Step-by-step explanation:
The formula for finding the circumference of a circle is C = 2πr = πd. Because the problem approximates π = 3.14 all we need to do is multiply 3.14 by 2 and r. It is given that r = 8.5 cm so therefore C is 3.14 x 2 x 8.5 = 53.58 cm.
How does Hamlet's view of death change throughout the play?.
Being afraid of the unknown prevents Hamlet from using death as a solution to end his difficulties.
Hamlet's perspective on death changes as he comes to terms with the fact that it is inevitable and he isn't sure he wants to experience it since death might not be preferable to life. Hamlet repeatedly longs for death to put an end to his suffering due to his sadness and agony, but he hesitates since death is forbidden in the Christian religion for fear of being sentenced to eternal torment in hell.We also learn that since another factor contributing to Hamlet's terrible demise was his inability to "do" rather than just "be." His speech, which is primarily about death, demonstrates his propensity to reflect rather than act.This is how Hamlet's view of death changes throughout the play.

at a football stadium 4% of the fans in the attendance were teenagers if there were 390 teenagers at the football stadium ,what was the total number of people at the stadium
The total number of people in the football stadium is 9750.
How to find the total number of people in the stadium?At the football stadium, 4 percent of the fans in the attendance were teenagers.
There are 390 teenagers at the football stadium. The total number of people in the stadium is as follows:
let
x = total number of people in the stadium
Hence,
390 = 4% of x
390 = 4 / 100 × x
390 = 4x / 100
cross multiply
39000 = 4x
divide both sides of the equation by 4
x = 39000 / 4
x = 9750
Therefore,
total number of people in the stadium = 9750

the circle passes through the point ( 7 , 6 ) (7,6)(, 7, comma, 6, ). what is its radius?
We cannot determine the center or radius of the circle based on the given information.
How to find the radius of the circle passing through the point (7, 6)?To find the radius of the circle passing through the point (7, 6), we need to determine the center of the circle.
Let's assume that the center of the circle is (a, b). Since the circle passes through point (7, 6), we can set up an equation using the distance formula between the center (a, b) and point (7, 6) as follows:
√((7 - a)² + (6 - b)²) = r
where r is the radius of the circle.
We can see that this equation represents the distance between the center of the circle and the point (7, 6) is equal to the radius of the circle.
We also know that the distance between the center of the circle and any point on the circle is equal to the radius. Therefore, if we can find the distance between (a, b) and another point on the circle, we can solve for the radius.
However, we do not have any other information about the circle, such as another point or the equation of the circle. Therefore, we cannot determine the center or radius of the circle based on the given information.

Step-by-step explanation:
chegg suppose we take a single observqation froma bernouilli population, where the mean is known to be restruction p [1/3, 2/3] what is the maximum likellhiood estimator
The maximum likelihood estimator (MLE) for a single observation from a Bernoulli population, where the mean is known to be restricted to p [1/3, 2/3], is p = 0.
The maximum likelihood estimator (MLE) for a single observation from a Bernoulli population with a known mean restriction p [1/3, 2/3] can be found by maximizing the likelihood function.
In this case, the likelihood function can be defined as the probability of obtaining the observed value given the parameter p. Since the population follows a Bernoulli distribution, the likelihood function can be expressed as:
\(L(p) = p^x * (1-p)^(1-x)\)
where x is the observed value (0 or 1).
To find the MLE, we need to find the value of p that maximizes the likelihood function. Taking the derivative of the log-likelihood function with respect to p and setting it equal to zero, we can solve for the MLE.
The log-likelihood function for a single observation from a Bernoulli distribution is:
\(log L(p) = x * log(p) + (1-x) * log(1-p)\)
Taking the derivative with respect to p:
\(d/dp (log L(p)) = (x/p) - ((1-x)/(1-p))\)
Setting it equal to zero and solving for p:
\((x/p) - ((1-x)/(1-p)) = 0\)
Simplifying the equation, we get:
\(x(1-p) - (1-x)p = 0\)
Expanding the equation further, we get:
x - px - p + xp = 0
2xp - 2p = x
Factoring out p, we get:
\(p(2x-2) = x\)
Dividing both sides by (2x-2), we get:
p = x / (2x-2)
In this case, since the mean is restricted to the range [1/3, 2/3], we need to consider the possible values of x (0 or 1) and substitute them into the equation to find the MLE.
For x = 0:
p = 0 / (2*0-2)
= 0
For x = 1:
p = 1 / (2*1-2)
= 1 / 0
= undefined
Therefore, the maximum likelihood estimator (MLE) for a single observation from a Bernoulli population, where the mean is known to be restricted to p [1/3, 2/3], is p = 0.

twenty-one percent of all light emitting diode (led) displays are manufactured by samsung. what is the probability that in a collection of two independent led hdtv purchases, at least one is a samsung? (round your answer to 3 decimal places.)
The probability of at least one is a Samsung in the purchase collection of two independent LED HDTV is equal to 0.376.
Percent of all LED display manufactured by Samsung = 21%
Probability that at least one purchase is Samsung
= 1 - Probability that both purchases are not Samsung
Probability that the first purchase is not Samsung is 1 - 0.21 = 0.79.
The probability that the second purchase is also not Samsung is also 0.79.
Since the purchases are independent,
Multiply these probabilities to get the probability that both purchases are not Samsung,
P(neither is Samsung)
= 0.79 x 0.79
= 0.6241
The probability that at least one purchase is Samsung is,
P(at least one is Samsung)
= 1 - P(neither is Samsung)
= 1 - 0.6241
= 0.3759
Rounding to 3 decimal places, we get,
P(at least one is Samsung) = 0.376
Therefore, the probability that in a collection of two independent LED HDTV purchases, at least one is a Samsung is 0.376.

Blaine's take-home pay is $2,500 each month, and he has created a monthly budget to become more aware of where his money goes. His budget is shown below. Blaine finds that he can join a cheaper gym for $40/month, reduce his spending money to $200, and find a phone and internet package for $175. How much will these choices save him each month?
Answer:
Amount Blaine save = $250
Step-by-step explanation:
Total take home pay = $2,500
Original budget:
Rent + electricity bills = $990
Food/groceries = $525
Gas + insurance = $320
Spending money = $235
Cellphone + Internet = $250
Gym membership = $180
Total = $2,500
New budget:
Rent + electricity bills = $990
Food/groceries = $525
Gas + insurance = $320
Spending money = $200
Cellphone + Internet = $175
Gym membership = $40
Total = $2,250
How much will these choices save him each month?
Amount Blaine save = Total take home - new budget
= $2,500 - $2,250
= $250
Amount Blaine save = $250

The second derivative test can always be used to determine whether a critical number is a relative extremum. O True O False
The statement "The second derivative test can always be used to determine whether a critical number is a relative extremum" is False.
The second derivative test is a useful method for determining if a critical number is a relative extremum (maximum or minimum).
However, it cannot always be used, as it is inconclusive when the second derivative is equal to zero or undefined. In these cases, other methods such as the first derivative test or analyzing the function's behavior around the critical number must be used.
To apply the second derivative test, follow these steps:
1. Find the first derivative (f') of the function.
2. Identify the critical numbers by setting f' equal to zero or where it's undefined.
3. Find the second derivative (f'') of the function.
4. Evaluate f'' at each critical number. If f'' > 0, it's a relative minimum; if f'' < 0, it's a relative maximum. If f'' = 0 or undefined, the test is inconclusive.
