Step-by-step explanation:
This is a 60, 90, 30. It's a special triangle.
2z = 24
z = 12
If x = z\(\sqrt{3}\)
then x = 12\(\sqrt{3}\)
y = z itself
So y = 12

What is 50% of 100%?
Answer:
We need to determine 50% of 100 now and the procedure explaining it as such
Step 1: In the given case Output Value is 100.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 100 = 100%.
Step 4: In the Same way, x = 50%.
Step 5: On dividing the pair of simple equations we got the equation as under
100 = 100% (1).
x = 50% (2).
(100%)/(x%) = 100/50
Step 6: Reciprocal of both the sides results in the following equation
x%/100% = 50/100
Step 7: Simplifying the above obtained equation further will tell what is 50% of 100

Find the value of L that Will Maximize the profit Q=L²e^0.01L
The minimum profit occurs at L = 0, where Q = 0.
To find the value of L that maximizes the profit Q = L²\(e^{(0.01L)\).
We need to differentiate Q with respect to L and find the critical points where the derivative equals zero.
Then we can determine whether each critical point is a maximum or a minimum by examining the second derivative.
Testing for critical points:Q = L²\(e^{(0.01L)\)
Q' = \(2Le^{(0.01L)\) + \(0.01 L^2e^{(0.01L)\)
= 0(2L + 0.01L²) \(e^{(0.01L)\)
= 0L (critical point) or 200 \(e^{(0.01L)\)
= 0 (extraneous, ignore)
2L + 0.01L² = 0L(2 + 0.01L) = 0L = 0 or L = -200 (extraneous, ignore)
The only critical point is at L = 0.
Testing for maximum or minimum:Q'' = \(2e^{(0.01L)\) + 0.02Le^(0.01L) + 0.0001L²\(e^{(0.01L)Q''(0)\)
= \(2e^{(0)\) = 2Since Q''(0) > 0,
The critical point at L = 0 is a minimum.
Therefore, there is no value of L that maximizes the profit.

The values of L that will maximize the profit are 0 and -200
Finding the value of L that will maximize the profitFrom the question, we have the following parameters that can be used in our computation:
\(Q = L\²e^{0.01L\)
Differentiate the function
So, we have
\(Q' = \frac{L \cdot (L + 200) \cdot e^{0.01L}}{100}\)
Set the equation to 0
\(\frac{L \cdot (L + 200) \cdot e^{0.01L}}{100} = 0\)
Cross multiply
\(L \cdot (L + 200) \cdot e^{0.01L} =0\)
When expanded, we have
L = 0, L + 200 = 0 and \(e^{0.01L} =0\)
When solved for L, we have
L = 0 and L = -200
Hence, the values of L are 0 and -200

3(y+1/4)>3/4 determine the value of y for the inequality
Therefore, the solution to the inequality 3(y + 1/4) > 3/4 is y > 0.
What is inequality?An inequality is a mathematical statement that shows a relationship between two values, which are not necessarily equal. Inequalities are represented using symbols such as > (greater than), < (less than), ≥ (greater than or equal to), and ≤ (less than or equal to). Inequalities are commonly used in algebra and other areas of mathematics, as well as in real-world applications such as finance, economics, and science. They can be used to represent constraints or limits on a variable, such as the maximum or minimum value that it can take.

2. The number of violent crimes committed in a day possesses a distribution with a mean of 2.8 crimes per day and a standard deviation of 4 crimes per day. A random sample of 100 days was observed, and the sample mean number of crimes for the sample was calculated. Describe the sampling distribution of the sample means. (5 points) a.) shape unknown with mean of 2.8 and a standard deviation of 0.4
Options :
a.) shape unknown with mean of 2.8 and a standard deviation of 0.4 b.) approximately normal with mean of 2.8 and standard deviation of 4 C.) shape unknown with mean of 2.8 and standard deviation of 4 d.) approximately normal with mean of 2.8 and standard deviation of 0.4
Answer: d.) approximately normal with mean of 2.8 and standard deviation of 0.4.
Step-by-step explanation:
Given that :
Population Mean (m) = 2.8
Population Standard deviation (s) = 4
Sample size = 100
The mean of the sampling distribution is equal to the population mean, according to the central limit theorem. As the size of the sample increases, the mean if the sample distribution converges to that if the population mean.
Hence, sample mean = 2.8
The sample standard deviation (standard error) :
Standard Error = population standard deviation / √sample size
= s/√n
= 4 / √100
= 4/10
= 0.4
Using the Central Limit Theorem, it is found that the correct description of the sampling distribution of the sample means is:
Approximately normal, with mean of 2.8 and standard deviation of 0.4.
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).
For a variable of unknown distribution, the Central Limit Theorem can be applied if the sample size is larger than 30.In this problem, the population has an unknown distribution, with mean \(\mu = 2.8\) and standard deviation \(\sigma = 4\)
The sampling distribution of the sample means of size 100 has:
Approximately normal shape, as the sample size is \(n = 100 > 30\).Mean \(\mu = 2.8\)Standard deviation \(s = \frac{4}{\sqrt{100}} = 0.4\).A similar problem is given at https://brainly.com/question/14099217

Point D is 8 units away from the origin along the x-axis, and is 6 units away along the y-axis. Which of the following could be the coordinates of Point D
Answer:
The distance between two points (x₁, y₁) and (x₂, y₂) is given by:
\(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)
Now we know that point D, which we can write as (x, y), is at a distance of 8 units from the origin.
Where the origin is written as (0, 0)
We also know that point D is 6 units away along the y-axis.
Then point D could be:
(x, 6)
or
(x, -6)
Now, let's find the x-value for each case, we need to solve:
\(8 = \sqrt{(x - 0)^2 + (\pm6 - 0)^2}\)
notice that because we have an even power, we will get the same value of x, regardless of which y value we choose.
\(8 = \sqrt{x^2 + 36} \\\\8^2 = x^2 + 36\\64 - 36 = x^2\\28 = x^2\\\pm\sqrt{28} = x\\\pm 5.29 = x\)
So we have two possible values of x.
x = 5.29
and
x = -5.29
Then the points that are at a distance of 8 units from the origin, and that are 6 units away along the y-axis are:
(5.29, 6)
(5.29, -6)
(-5.29, 6)
(-5.29, -6)
Which statement about 4 + 2x is true?
Answer:

Step-by-step explanation:
Peter is the owner of a hardware supply shop. He has hired you to check his machines calibration prior to starting production on a large order. To check this, you set the machine to create 2.0 inch nails and manufacture a random sample of 200 nails. That sample of nails has an average length of 2.024 inches with a standard deviation of 0.205 inches.
Does this sample provide convincing evidence that the machine is working properly or should it be shut down for repairs?
Answer:If we compare the p value and the significance level assumed we see thatso we can conclude that we have enough evidence to FAIL reject the null hypothesis, so we can conclude that the true mean is not different from the specification at 1% of signficance.
Step-by-step explanation:
The machine is working properly based on the convincing evidence provided by the sample.
How to calculate the test statistics.For the null hypothesis, we would test that:
H0 : p = 2
For the alternate hypothesis, we would test that:
Ha > p = 2
In Mathematics, the test statistics of a given sample is calculated by using this formula:
\(Z=\frac{x\;-\;u}{\frac{\sigma}{\sqrt{n} } }\)
Where:
x is the sample mean.u is the mean.is the standard deviation.n is the sample size.Substituting the given parameters into the formula, we have;
\(Z=\frac{2.024\;-\;2}{\frac{0.205}{\sqrt{200} } }\\\\Z=\frac{0.024}{\frac{0.205}{14.14} }\\\\Z=\frac{0.024}{0.0145 }\)
Z = 1.66.
For the p-value:
P(Z > Zo) = P(Z > 1.66)
P(Z > 1.66) = P(Z < -1.66)
P(Z < -1.66) = 0.0485.
From the z-table, a z-score of 1.66 corresponds has a p-value of 0.0485. Therefore, the p-value for this test is 0.0485 < 2 while assuming a confidence level of 95%.
In conclusion, we fail to reject the null hypothesis because 0.0485 < 2.

9t+6
in standard form. asap!
The equation -6 = 0 is not true, which means that there is no solution to the equation 9t+6 in standard form. This is because we cannot write the equation in the form \(ax + by = c\) , since there is no value of c that would satisfy the equation.
What is the expression to have the variables?To write 9t+6 in standard form, we need to rearrange the expression to have the variables first, followed by the constant term. The standard form of a linear equation is:
\(ax + by = c\)
where a, b, and c are constants, and x and y are variables.
To rearrange 9t+6, we first need to group the t term and the constant term together. We can do this by adding 0t to the expression:
\(9t + 0t + 6\)
Now, we can rearrange the terms so that the variable term comes first:
\(9t + 0t = 9t\)
Finally, we can write the expression in the standard form:
\(9t + 0t = 9t + 6\)
This can be simplified further by removing the 0t term:
\(9t = 9t + 6\)
We can now move the constant term to the other side of the equation by subtracting 6 from both sides:
\(9t - 6 = 9t + 6 - 6\)
\(9t - 6 = 9t\)
\(-6 = 0\)
Therefore, The equation \(-6 = 0\) is not true, which means that there is no solution to the equation \(9t+6\) in standard form. This is because we cannot write the equation in the form \(ax + by = c\) , since there is no value of c that would satisfy the equation.

Autohide sh Growth: Math 6+ GA 2015 Question ITU Shelf nositi
Answer:
a. Angel has a greater flat fee
b. Difference = $130
Step-by-step explanation:
Given
Rose:
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
Angel
Guests --- Charges
10 -------- $180
15 -------- $255
25 -------- $405
30 -------- $480
Solving (a): Who charges the greater flat fee?
We have that the flat fee of Rose is:
\(Flat\ Fee = \$50\)
For Angel, we need to determine the equation of the given table
Start by calculating the slope (m) of the table
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where x and y represent any two corresponding values of the guests and the charges.
\((x_1,y_1) = (10, 180)\)
\((x_2,y_2) = (30, 480)\)
So: \(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes
\(m = \frac{480 - 180}{30 - 10}\)
\(m = \frac{300}{20}\)
\(m = 15\)
Next, we calculate the equation using:
\(y - y_1 = m(x - x_1)\)
Where
\(m = 15\)
\((x_1,y_1) = (10, 180)\)
\(y - 180 = 15(x - 10)\)
\(y - 180 = 15x - 150\)
Add 180 to both sides
\(y - 180 + 180 = 15x - 150 + 180\)
\(y= 15x + 30\)
From the equation above:
The slope = 15 --- This represents the hourly rate
and
y intercept = 30 --- This represents the flat fee
This is better represented as:
Angel
\(Flat\ Fee = \$30\)
\(Rate = \$15\)
and
Rose:
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
By comparison, Angel has a greater flat fee
Solving (b): Difference between total charges of 50 guests for both caterers.
For angel, the equation is:
\(y= 15x + 30\)
and x = 50.
So:
\(y = 15 * 50 + 30\)
\(y = 750 + 30\)
\(y = 780\)
For Rose,
First, we need to determine the equation.
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
The equation is:
\(y = Flat\ Fee + Rate * x\)
\(y = 50 + 12 * x\)
So, the total charges for 50 guests is:
\(y = 50 + 12 * 50\)
\(y = 50 + 600\)
\(y = 650\)
The difference is then calculates as:
\(Difference = 780 - 650\)
\(Difference = \$130\)
