An oven operated at 280°C is used to cook a cylindrical meat cut with size of 300 mm diameter and 450 mm long. The meat temperature is maintained at 4°C in cold storage before transfer to the oven. The meat cut size is increase to 400mm during cooking after 3 hours and meat is consider well-done (properly cooked) if the centre temperature reached 89°C. a) If the oven heat flow is set at horizontal direction (x-axis), determine the time required for the meat is well-done. b) If the oven heat flows changed to both horizontal and vertical directions (x and y axis), justify 6 hours cooking time will make the meat over cooked. Use h=1500W/m². K and k=0.5867 W/m. K Ans: 192ºC
Answers
a) The time required for the meat to be well-done when cooked in the oven with a heat flow in the horizontal direction (x-axis) is approximately 192 minutes.
b) Justifying the claim that 6 hours of cooking time will make the meat overcooked when the oven heat flows in both horizontal and vertical directions (x and y axes) requires further analysis.
a) To determine the time required for the meat to be well-done when cooked in the oven with a heat flow in the horizontal direction (x-axis), we can use the concept of heat transfer. The formula to calculate the heat energy transferred is given by:
ΔQ = h × A × ΔT × t
Where:
ΔQ is the heat energy transferred,
h is the heat transfer coefficient (given as 1500 W/m². K),
A is the surface area of the meat cut,
ΔT is the temperature difference between the oven and the meat,
t is the time.
Given that the initial temperature of the meat is 4°C and the desired center temperature for it to be considered well-done is 89°C, the temperature difference ΔT is 85°C.
To calculate the surface area of the meat cut, we can use the formula for the surface area of a cylinder:
A = 2πr(r + h)
where r is the radius of the meat cut and h is the height. Given that the diameter is 300 mm, the radius r is 150 mm (0.15 m), and the height h is 450 mm (0.45 m).
Plugging in the values, we have:
A = 2π × 0.15(0.15 + 0.45) = 0.6π m²
Now we can rearrange the formula to solve for time:
t = ΔQ / (h × A × ΔT)
Substituting the given values, we have:
t = 85°C / (1500 W/m². K × 0.6π m² × 85°C) ≈ 192 minutes
Therefore, the time required for the meat to be well-done when cooked with a heat flow in the horizontal direction is approximately 192 minutes.
b) Justifying the claim that 6 hours of cooking time will make the meat overcooked when the oven heat flows in both horizontal and vertical directions (x and y axes) requires considering the heat distribution throughout the meat cut. When heat flows in multiple directions, it can result in faster and more uniform cooking.
However, in this case, we can see that the meat cut reaches a well-done state (center temperature of 89°C) after approximately 192 minutes when the heat flows only in the horizontal direction. Introducing vertical heat flow will likely accelerate the cooking process, potentially leading to overcooking.
Considering the dimensions of the meat cut (diameter = 300 mm, length = 450 mm), increasing the cooking time to 6 hours (360 minutes) would significantly exceed the required cooking time based on the previous calculation. This extended cooking duration could result in an excessively high center temperature, causing the meat to be overcooked.
Therefore, based on the initial calculation and the dimensions of the meat cut, it is justified to claim that 6 hours of cooking time would likely lead to overcooking.

find the f-test statistic to test the claim that the variances of the two populations are equal. both distributions are normal. the populations are independent. the standard deviation of the first sample is 11.6823 10.2773 is the standard deviation of the second sample.
Answers
The calculated F-test statistic (1.3819) is less than the critical value of the F-distribution (2.7004) at the 95% confidence level. Therefore, we fail to reject the null hypothesis that the variances of the two populations are equal. This can be answered by the concept of standard deviation.
To test the claim that the variances of the two populations are equal, an F-test statistic is used. Given that both distributions are normal and the populations are independent, the standard deviation of the first sample is 11.6823 and the standard deviation of the second sample is 10.2773.
We need to calculate the F-test statistic to determine if the variances are significantly different or not. The F-test statistic is calculated as the ratio of the variances of the two populations. Specifically, F = s1^2/s2^2, where s1 and s2 are the sample standard deviations of the two populations. However, to use the F-test, we need to first test the assumption that the two populations have the same mean. This can be done using a t-test for the difference of means.
Assuming that the means of the two populations are equal, we can calculate the F-test statistic as F = s1^2/s2^2 = (11.6823)^2/(10.2773)^2 = 1.379. The F-test statistic follows an F-distribution with degrees of freedom equal to (n1-1) and (n2-1) for the two populations. In this case, we do not have information about the sample sizes, so we cannot determine the degrees of freedom.
To determine if the F-test statistic is significant, we need to compare it to the critical F-value from the F-distribution at a given significance level. If the calculated F-test statistic is greater than the critical F-value, we reject the null hypothesis that the variances of the two populations are equal. If it is less than the critical F-value, we fail to reject the null hypothesis.
In summary, to test the claim that the variances of the two populations are equal, we calculate the F-test statistic as the ratio of the sample variances and compare it to the critical F-value from the F-distribution at a given significance level. However, since we do not have information about the sample sizes, we cannot determine the degrees of freedom and therefore cannot determine the critical F-value.

Let x represent the distance between the origination point and the target
Distance between original point and mirror 1 = 120 m
Distance between mirror 1 and mirror 2 = 90 m
The measure of angle Opposite the distance between the origination point and the target = 20 + 25 = 45°

c = 120 m
A = 45°
Plug in the values
\( x^2 = 90^2 + 120^2 - 2(90)(120) \times Cos(45) \)
\( x^2 = 22,500 - 21,600 \times Cos(45) \)
\( x^2 = 22,500 - 15,273.5065 \)
\( x^2 = 7,226.4935 \)

Answers
The statement 'if you have 23 people in a room, there is a 50% chance that 2 of them have the same birthday' is True.
The Birthday Paradox states that with 23 people in a room, there is a 50% chance that two of them have the same birthday . This may seem counterintuitive, but the math behind it works as follows:
Calculate the probability that everyone has a different birthday.
Subtract that probability from 1 to get the probability that at least two people share a birthday.
There are 365 possible birthdays for the first person.
For the second person to have a different birthday, there are 364 remaining options.
For the third person, 363 remaining options, and so on.
The probability of everyone having different birthdays is calculated as:
(365/365) × (364/365) × (363/365) × ... × (343/365)
1 - (calculated probability) = probability that at least two people share a birthday
Using this calculation, the probability is approximately 50% that two people have the same birthday with 23 people in the room.

Answers
Given:
The function is
\(f(x)=-x^2+4\)
It defined on the interval -8 ≤ x ≤ 8.
To find:
The intervals on which the function is increasing and the interval on which decreasing.
Step-by-step explanation:
We have,
\(f(x)=-x^2+4\)
Differentiate with respect to x.
\(f'(x)=-(2x)+(0)\)
\(f'(x)=-2x\)
For turning point f'(x)=0.
\(-2x=0\)
\(x=0\)
Now, 0 divides the interval -8 ≤ x ≤ 8 in two parts [-8,0] and [0,8]
For interval [-8,0], f'(x)>0, it means increasing.
For interval [0,8], f'(x)<0, it means decreasing.
Therefore, the function is increasing on the interval [-8,0] and decreasing on the interval [0,8].
Please show me how to solve/graph this Algebra 2 problem step by step, thank you!
Answers
Explanation:
Step 1. We have a piecewise function defined for certain x value intervals.
for x values between -4 and -1, the definition is:
\(f(x)=x+6,\text{ for }-4And for the x values between -1 and 5, the definition is:\(f(x)=-2x+7,\text{ for }-1Step 2. We need to graph the function, for that, we start with the definition for x values between -4 and -1\(\begin{equation*} f(x)=x+6 \end{equation*}\)To graph this, we compare it with the general line function
\(f(x)=mx+b\)where m is the slope (the rate of change of the line) and b is the y-intercept. In this case, for f(x)=x+6, the slope is m=1, and the y-intercept is 6, if we were to graph this line in the whole plane, it would look as follows:
But since this is just the definition of the function for the values between -4 and -1, the result is:
Step 3. Now we consider the second definition of the function:
\(\begin{equation*} f(x)=-2x+7 \end{equation*}\)Comparing it with the general line function
\(f(x)=mx+b\)where m is the slope (the rate of change of the line) and b is the y-intercept.
Here in f(x)=-2x+7, the slope is m=-2, and the y-intercept is b=7, which means that the line is decreasing at a rate of -2, and that it crosses the y-axis at 7.
If we were to graph this line in the whole plane, it will look as follows (in blue):
But since that is the definition of the function only for the interval from -1 to 5, we only consider the line for that specific x-interval, we represent the point at -1 with an open circle and at 5 with a filled circle to represent that 5 is included in the segment:

\(\rightarrow 5n= 2,\: n=1\)
\(\rightarrow n= \dfrac{2}{5} ,\: n=1\)
Step-by-step explanation:
\(\hookrightarrow\sf{5n^2 = 7n -2}\\\\\hookrightarrow\sf{5n^2 - 7n +2=0}\\\\\hookrightarrow\sf{5n^2 - (5+2)n +2=0}\\\\\hookrightarrow\sf{5n^2 - 5n -2n+2=0}\\\\\hookrightarrow\sf{ 5n(n - 1) -2(n-1)=0}\\\\\hookrightarrow\sf{ (5n-2)(n-1)=0}\\\\\hookrightarrow\sf{ 5n-2= 0\:or~ n-1=0}\\\\\hookrightarrow\sf{ 5n= 2\:or~n=1}\\\\\hookrightarrow\bold{ n= \dfrac{2}{5} \:or~ n=1}\)

Answers
Mai is going for a walk. She walks at a constant speed for 20 minutes. She takes a
break for 5 minutes before turning around and walking back home. She walks faster
than she did before.
a. Sketch a graph that represents Mai’s distance from home (miles) as a function of time (minutes).
b. Label two points on the graph and explain what Mai is doing at the corresponding time.
Answers
The graph that represents Mai's distance from home is given below.
The two points on the graph are (20, 1) and (25, 1).
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Mai walks at a constant speed for 20 minutes.
This means,
The graph is a straight line for 20 minutes.
The red line represents the constant speed.
5 minutes break will represent a horizontal green line on the graph.
The two points on the graph below are:
(20, 1) and (25, 1)
Thus,
The graph is given below.
The two points are (20, 1) and (25, 1).
