The average of 8,14, and x is 12, what is the value of x?

Tyler needs to make 8 invitations each day to finish his goal.

Retrieving the data from other sources:

Since Tyler wants to beat his goal, in a week (7 days) with x invitations.

7x+66=122

7x+66 -66=122 -66

7x= 56

x=8

So Tyler needs to make 8 invitations each day to finish his goal.

You can never achieve break even by selling any number of boxes of candy if it costs them an additional $3 to manufacture each box of candy.

In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even."

Although these opportunity costs have been paid and then capital has received the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."

Fixed cost (in manufacturing) = $500

Manufacturing cost of each candy = $3

and selling price of candy = $3

let x be a box of candy sold,

hence for no of box to be sold for a break even,

3x + 500 = 3x

but if you see above equation, that has no solution

Hence by providing each candy at $3 with $500 fixed cost and selling cost again at $3 you cannot achieve a break-even point.

hence there is no solution, and you will never be able to achieve break even.

The value of y is 18

Similar triangles have the same corresponding angle measures and proportional side lengths. The angles of the two triangle must be equal and it not necessary they have equal sides.

Therefore the corresponding angles of similar triangles are congruent and the ratio of corresponding sides of similar triangles are equal.

Therefore;

14/21 = 12/y

14y = 21 × 12

14y = 252

divide both sides by 14

y = 252/14

y = 18

Therefore the value of y is 18.

Answer:

\((a)\ L = 18.84\) --- arc length

\((b)\ A = 113.04\) --- sector area

Step-by-step explanation:

Given

\(r = 12\)

\(\theta = 90\)

Solving (a): The arc length

This is calculated using:

\(L = \frac{\theta}{360} * 2\pi r\)

So, we have:

\(L = \frac{90}{360} * 2* 3.14 * 12\)

\(L = 0.25* 2* 3.14 * 12\)

\(L = 18.84\)

Solving (b): The sector area

This is calculated using:

\(A = \frac{\theta}{360} * \pi r^2\)

So, we have:

\(A = \frac{90}{360} * 3.14 * 12^2\)

\(A = 0.25 * 3.14 * 12^2\)

\(A = 113.04\)

The difference between the observed and expected number of late departures is statistically significant, we need to perform a binomial test by calculating the probability of observing 16 or more late departures out of 300 flights assuming the null hypothesis is true. If the resulting p-value is less than 0.05, we can conclude that the difference is statistically significant.

Based on the given information, an airline with a 95% on-time departure rate has 16 out of 300 flights with late departures. The question asks whether the difference between what occurred (16 late departures) and what you would expect by chance is statistically significant.
To determine if the difference is statistically significant, we need to conduct a hypothesis test. In this case, we can use a binomial test since we are dealing with two possible outcomes: on-time departure or late departure.
The null hypothesis (H0) assumes that the observed number of late departures is equal to what would be expected by chance. The alternative hypothesis (Ha) assumes that there is a significant difference between the observed and expected values.
In this case, the expected number of late departures can be calculated by multiplying the total number of flights (300) by the expected on-time departure rate (95%). This gives us an expected value of 300 * 0.05 = 15.
To perform the binomial test, we can calculate the probability of observing 16 or more late departures out of 300 flights, assuming the null hypothesis is true. This probability can be calculated using the binomial probability formula or by using statistical software.
If the resulting probability (also known as the p-value) is less than the significance level (usually 0.05), we can reject the null hypothesis and conclude that the difference between what occurred and what would be expected by chance is statistically significant. Otherwise, if the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that the difference is not statistically significant.

Answer:

\(6\).

Step-by-step explanation:

A line that goes through \((x_{0},\, y_{0})\) and \((x_{1},\, y_{1})\) where \(x_{0} \ne x_{1}\) would have a slope of \(m = (x_{1} - x_{0}) / (y_{1} - y_{0})\).

The slope of the line that goes through \((8,\, 4)\) and \((-1,\, 1)\) would thus be:

\(\begin{aligned}m_{2} &= \frac{1 - 4}{(-1) - 8} \\ &= \frac{(-3)}{(-9)} \\ &= \frac{1}{3}\end{aligned}\).

Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is \((-1)\).

Thus, if \(m_{1}\) and \(m_{2}\) denote the slope of the first and second lines in this question, \(m_{1}\, m_{2} = (-1)\) since the two lines are perpendicular to one another. Since \(m_{2} = (1/3)\), the slope of the first line would be:

\(\begin{aligned} m_{1} &= \frac{(-1)}{m_{2}} \\ &= \frac{(-1)}{(1/3)} \\ &= (-3)\end{aligned}\).

Given that the first line goes through the point \((1,\, 0)\), the point-slope equation of that line would be:

\((y - 0) = (-3)\, (x - 1)\).

\(y = -3\, x + 3\).

Substitute in \(x = (-1)\) to find the \(y\)-coordinate of the point in question:

\(y = -3\times (-1) + 3 = 6\).

Answer:

  2.5%

Step-by-step explanation:

You want the percentage below 335 if the distribution is normal with a mean of 555 and a standard deviation of 110, using the empirical rule.

The z-score of 335 is ...

  Z = (X -µ)/σ

  Z = (335 -555)/110 = -220/110 = -2

The empirical rule tells you that 95% of the distribution is between Z = -2 and Z = 2. That is, 5% of the distribution is evenly split between the tails Z < -2 and Z > 2. Half that value is in each tail.

  P(X < 335) = 5%/2 = 2.5%

The percentage of people taking the test who score below 335 is 2.5%.

Step-by-step explanation:

To find the time it takes the T-shirt to reach its maximum height, we need to find the value of t when the velocity of the T-shirt is zero, because at this point the T-shirt has reached its maximum height and starts falling back down. We can find the velocity of the T-shirt by taking the derivative of the height equation with respect to time:

v(t) = h'(t) = 72

The velocity of the T-shirt is a constant 72 feet per second, so it will never reach a velocity of zero and will never reach its maximum height. The T-shirt will keep going up indefinitely.

If the problem had specified that the T-shirt was launched with an initial upward velocity of -72 feet per second (meaning it was launched downward), then we could have found the time it takes the T-shirt to reach its maximum height by setting v(t) = 0 and solving for t. In this case, we would find that t = 1, so it would take the T-shirt 1 second to reach its maximum height. The maximum height would be h(1) = -16 + 72(1) + 6 = 62 feet.

Step-by-step explanation:

The domain of each function is given as follows:

11. All real values except x = -2 and x = 4.

12. All real values except x = -1 and x = 1.

13. All real values except x = -2.

The domain of a function is the set that contains all the possible input values for the function.

The functions in this problem are rational functions, meaning that all the values of x that make the denominator zero are excluded from the domain.

Then the excluded values are obtained as follows:

11. x² - 4 = 0 -> x = -2 and x = 2.

12. x² - 1 = 0 -> x = -1 and x = 1.

13. x + 2 = 0 -> x = -2.

Answer: Classroom B is 25% occupied. The ratio of the occupancy of Classroom A to Classroom B is 5:3. How many students can fit in Classroom B? 84 students.

Step-by-step explanation:

The angles <1, <2, and <3 will not add up to 180 degrees. The angles <1 and <2 are alternate interior angles, and the angles <2 and <3 are also alternate interior angles, AB is parallel to CD.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is always equal to 180 degrees. This means that if you measure the angles inside any triangle and add them up, the result will always be 180 degrees. This property holds true for all types of triangles, whether they are equilateral, isosceles, or scalene.

To understand this property, consider a triangle ABC with interior angles angle A, angle B, and angle C. If we draw a line segment from vertex A to a point D on side BC such that it is parallel to the side AB, then we can see that angle A and angle C are alternate interior angles of the parallel lines AB and CD. Similarly, angle B and angle C are alternate interior angles of the parallel lines BC and AD.
