The solutions to the quadratic equation will be - 6 + √7 and - 6 - √7. Then the correct options are C and F.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The quadratic equation is given below.

x² + 12x+36 = 7

Simplify the equation, then we have

x² + 12x + 36 = 7

x² + 12x + 29 = 0

Get the solution by formula method. Then we have

x = [- 12 ± √(12² - 4 × 1 × 29)] / (2 × 1)

x = [- 12 ± √(144 - 116)] / (2)

x = (- 12 ± √28) / 2

x = (- 12 ± 2√7) / 2

x = - 6 ± √7

x = - 6 + √7, - 6 - √7

The solutions to the quadratic equation will be - 6 + √7 and - 6 - √7. Then the correct options are C and F.

Answer:

B; the angles of the triangle and the hypothnuse can be multiplied.

The perimeter of the rectangle is 13.30 units

From the question, we have the following parameters that can be used in our computation:

(-2 , -2), (1, -1.5) and (-1, 1.5)

The side lengths are calculated using

Lentghs = √[(x2 - x1)² + (y2 - y1)²]

So, we have

Lentgh 1 = √[(-2 - 1)² + (-2 + 1.5)²] = 3.04

Lentgh 2 = √[(1 + 1)² + (-1.5 - 1.5)²] = 3.61

So, we have

PErimeter = 2 * (3.04 + 3.61)

What is Derivative?

The derivative of a function of a real variable in mathematics describes the sensitivity of the function value to a change in its argument. Calculus relies heavily on derivatives.

Solution:

Let the ture positive numbers be x,(x,y>0)

x + y = 20 -------- Given

We need to maximise \(xy^{2}\)

x = 20 - y

f(y) = (20 - y)*\(y^{2}\)

f(y) = 20\(y^{2}\) - \(y^{3}\)

f'(y) = 0

(a) To ensure that at least two people share the same birth month among 75 people, at least 76 people are needed.

(b) The minimum number of people needed in a group to guarantee that at least 6 people share the same birthday is 6.

(a) To find the minimum number of people needed in a group to ensure that at least two people share the same birth month, we can use the pigeonhole principle.

Divide the 12 months of the year into 12 "pigeonholes" or containers, one for each month.

Since there are 75 people in the group, try to put each person in their corresponding birth month container.

If you can put all 75 people into the 12 containers such that each container has at most 6 people, then there is no pair of people who share the same birth month.

However, if you add one more person to the group, you will need to put them into one of the 12 containers. Since all 12 containers already have 6 people in them, this person must be put into a container that already has at least one person in it. Therefore, at least two people share the same birth month.

Therefore, the minimum number of people needed in a group to ensure that at least two people share the same birth month is 76.

(b) To find the minimum number of people needed in a group to guarantee that at least 6 were born on the same day, not considering the year, we can again use the pigeonhole principle.

Since there are 365 days in a non-leap year, divide the 365 days into 365 "pigeonholes" or containers, one for each day.

Since no one is born on Feb. 29, there are only 364 possible birthdays.

We want to find the minimum number of people needed in a group to ensure that at least 6 people share the same birthday.

To find this number, we can use a little trial and error. If we add the first 5 people, each person can have a unique birthday, but when we add the 6th person, they must share a birthday with one of the previous 5 people.

Therefore, the minimum number of people needed in a group to guarantee that at least 6 people share the same birthday is 6.

The expectation for the number of face cards when 10 cards are drawn, with replacement, from a standard deck is 2.3.

Expectations are the average outcome of a random event and are calculated based on the likelihood of each outcome.

In the case of drawing 10 cards, with replacement, from a standard deck, the expectation for the number of face cards (Jack, Queen, King) can be calculated. A standard deck consists of 52 cards, with 12 face cards and 40 non-face cards. The probability of drawing a face card is 12/52 or 0.23, and the probability of drawing a non-face card is 40/52 or 0.77.

Given these probabilities, we can calculate the expectation for the number of face cards as follows:

10 x (0.23) = 2.3.

This means that on average, we expect to draw

2.3 face cards

when we draw 10 cards from a standard deck.

It's important to keep in mind that the expectation is an average outcome, and the actual number of face cards drawn in a single experiment may be different. However, over many experiments, the average number of face cards will approach the expectation.

Based on the 1.5 × IQR rule for outliers, there is no evidence to support the student's claim because there is only one outlier at 58 minutes.

The interquartile range is the difference between upper and lower quartiles. The semi-interquartile range is half the interquartile range. When the data set is small, it is simple to identify the values of quartiles.

Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

The following interquartile ranges was calculated by using Excel:

Q₃ = 31.5

Q₁ = 20.5

Now, the interquartile range (IQR) is given by:

IQR = Q₃ - Q₁

IQR = 31.5 - 20.5

IQR = 11

Based on the 1.5 × IQR rule for outliers, we have:

1.5 × IQR = 1.5 × 11 = 16.5

Therefore, our fences will be 16.5 points below Q₁ and 16.5 points above Q₃:

Lower fence = 20.5 - 16.5 = 4.5

Upper fence = 4.5 + 31.5 = 36.

The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.

To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.

However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.

Step-by-step explanation:

For this question, you need to know several special relationships about circles. A radius goes from the center of a circle to any point on the circle. All the radii (not a typo, plural of radius is radii) are the same size, their measures are equal; we say they are congruent (the symbol is an equal sign with a ~over it)

In the diagram, OA and OB are congruent because they are radii. AC is a tangent, that means that it touches the circle at exactly one point, in this case at A. So since OA is a radius and AC is a tangent, they are perpendicular to each other (makes 90° angles). Then we can subtract 90 - 72 to find the angle OAB. Angle OAB is 14°. In triangle AOB, which has two sides the same, the opposite angles will also be congruent which means OBA is also 14° (OR you could use the exact same logic for OB perpendicular to BC and subtract, same calculation as before) . Once you have the two 14° angles in the triangle, you can use the fact that all the angles in a triangle add up to 180° So then, 14 + 14 + x =180. Solve this equation to find angle AOB. See image.

It can be checked by multiplying the divisor 32 by the quotient 74

We're 8 short of the goal of 2376, but notice how the remainder is 8. This is the amount to add on so we get to the goal of 2376

In other words,

32*74 + 8 = 2368+8 = 2376

You can think of it like having 2376 cookies and 32 friends. Each friend will get 74 cookies, and there will be 8 left over.

The x-coordinate of the x-intercept of line k is -5/2.

Since this point lies on the x-axis, its y-coordinate is 0.

Given that the line has a y-intercept at the point (0, p), where p is a positive constant. This means that when x = 0, y = p.

As we know that the equation of the line can be written as y = mx + b, where m is the slope and b is the y-intercept.

Here, the slope is the negative of the fraction 2p/5, so the equation of line k is y = -2p/5 x + p.

Substitute y = 0 into the equation and solve for x:

0 = -2p/5 x + p

Subtract p from both sides and then multiply by 5/(-2p):

-2p/5 x = -p

x = (-p)(5/2p)

x = -5/2

Therefore, the x-coordinate of the x-intercept of line k is -5/2.
