The correct answer include the following: A) The given value is a parameter for the week because the data collected represent a population.

In Statistics and Mathematics, a population can be defined as a set of similar items or events that comprises every member of a group and from which a researcher, scientist, or experimenter, obtains or generates data for a statistical study.

In this context, we can reasonably infer and logically deduce that the amount of voltage that was supplied to this homeowner's home represent a parameter for the week since the data collected represents a population.

Answer:

(-6,-3)->(3,7)

(-5,-5)->(5,9)

(-3,-3)->(6,7)

Step-by-step explanation:

The final answer is "5" which is a whole number and contains only two digits.

To evaluate the expression 15 - (11 wholes and 1 sixth) + 1 whole and 1 sixth, we need to convert the mixed numbers to improper fractions and then perform the subtraction and addition operation.

To convert 11 wholes and 1 sixth to an improper fraction, we will multiply the whole number by the denominator of the fraction, then add the numerator, and finally place the result over the denominator.

Therefore,11 wholes and 1 sixth = (11 × 6 + 1) / 6= 67 / 6

Similarly, 1 whole and 1 sixth = (1 × 6 + 1) / 6= 7 / 6

Now we substitute these values in the given expression and simplify it.

      15 - (11 wholes and 1 sixth) + 1 whole and 1 sixth= 15 - 67/6 + 7/6

                                                                                    = (15 × 6)/6 - 67/6 + 7/6

                                                                                    = (90 - 67 + 7)/6

                                                                                    = 30/6

                                                                                    = 5

Therefore, 15 - (11 wholes and 1 sixth) + 1 whole and 1 sixth is equal to 5 in terms of whole numbers.

So, the final answer is "5" which is a whole number and contains only two digits.

The measure of length PQ will be 22 units.

A triangle's third side is stated to be parallel to the line segment uniting its two midpoints, and it is also half as long as the third side.

Given:

PQ = 5x + 62, and MN = 6x-4

Now, using Mid- Point Theorem

PQ= 1/2 MN

-5x+ 62 = 1/2( 6x - 4)

-5x+ 62 = 3x - 2

-5x- 3x = -2 - 62

Answer:

During the month of September.

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

\(T(m) = 27\cos{(\frac{\pi}{6}(m-6))} + 45\)

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

\(T(m) = 27\cos{(\frac{\pi}{6}(m-6))} + 45\)

\(55 = 27\cos{(\frac{\pi}{6}(m-6))} + 45\)

\(27\cos{(\frac{\pi}{6}(m-6))} = 10\)

\(\cos{(\frac{\pi}{6}(m-6))} = \frac{10}{27}\)

Applying the inverse cosine to both sides:

\(\cos^{-1}{(\cos{(\frac{\pi}{6}(m-6))})} = \cos^{-1}{(\frac{10}{27})}\)

\(\frac{\pi}{6}(m-6) = 1.19\)

\(\pi(m-6) = 6*1.19\)

\(\pi m - 6\pi = 6*1.19\)

\(\pi m = 6*1.19 + 6\pi\)

\(m = \frac{6*1.19 + 6\pi}{\pi}\)

\(m = 8.27\)

8.27 months after January

8.27 + 1 = 9.27, so during the month of September.

The first step is to convert angle A = 23°23' to degrees. Recall, the interpretation of angle A is 23 degree 23 minutes. Also,

1 degree = 60 minutes

Let x = 23 minutes. Thus, we have these equations

1 = 60

x = 23

By crossmultiplying,

60x = 23

x = 23/60 = 0.3833

Thus,

angle A = 23 degrees + 0.3833 degrees = 23.3833 degrees

The triangle is shown below

Taking angle A as the reference angle,

hypotenuse = 42.75

opposite side = a

adjacent side = b

To find a, we would apply the sine trigonometric ratio which is expressed as

Sin# = opposite side/hypotenuse

Sin 23.3833 = a/47.25

By crossmultiplying,

a = 47.25Sin 23.3833

a = 18.75

To find b, we would apply the cosine trigonometric ratio which is expressed as

Cos# = adjacent side/hypotenuse

Cos 23.3833 = b/47.25

By crossmultiplying,

b = 47.25Cos 23.3833

b = 43.37

The given triangle is a right triangle. This means that one of its angles is 90 degrees. Thus,

angle C = 90 degrees

The sum of the angles in a traingle is 180 degrees. This means that

angle A + angle B + angle C = 180

23.3833 + angle B + 90 = 180

angle B + 113.3833 = 180

angle B = 180 - 113.3833

angle B = 66.62 degrees

It is known that 20% of all people given a certain medicine feel very bad in 2 minutes; Find the probability that among 14 people who are given this medicine:

a) At most 2 feel very bad in two minutes

b) At least 5 feel very bad in two minutes

c) From 2 to 4 they feel very bad in two minutes

Solution

This is a binomial distribution problem

A binomial experiment is one in which the probability of success doesn't change with every run or number of trials.

It usually consists of a number of runs/trials with only two possible outcomes, a success or a failure.

The outcome of each trial/run of a binomial experiment is independent of one another.

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = 14

x = Number of successes required

p = probability of success = probability of feeling bad after taking the medicine = 20% = 0.20

q = probability of failure = probability of NOT feeling bad after taking the medicine = 1 - 0.20 = 0.80

a) At most 2 feel very bad in two minutes

P(X ≤ 2) = P(X=0) + P(X=1) + P(X=2)

= 0.04398046511 + 0.15393162789 + 0.25013889532 = 0.44805098832 = 0.4481

b) At least 5 feel very bad in two minutes

P(X ≥ 5) = 1 - P(X < 5) = 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4)]

= 1 - [0.04398046511 + 0.15393162789 + 0.25013889532 + 0.25013889532 + 0.17197049053] = 0.12983962583 = 0.1298

c) From 2 to 4 they feel very bad in two minutes

P(2 ≤ X ≤ 4) = P(X=2) + P(X=3) + P(X=4)

= 0.25013889532 + 0.25013889532 + 0.17197049053 = 0.6722482811 = 0.6722

To find the leading coefficient of the polynomial function, we must first locate the leading term. In a polynomial function, the leading term is the term containing the highest power of x. In this polynomial function, the leading term is 10x2. The leading coefficient of a polynomial function is the coefficient of the leading term, and so the leading coefficient of this polynomial function is 10.

Since, The equation of the height with the time is provided and the balloon is thrown upwards against gravity from 5 feet, The answer is 0.255 sec.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

When gravity first exerts force on an object, its initial velocity defines how quickly the object moves. The final velocity, on the other hand, is a vector number that gauges a moving body's speed and direction after it has reached its maximum acceleration.

initial height = 5

final height =20

height to travel =20-5 =15

The given statement "For every positive x ∈ Q, there is a positive y ∈ Q for which y < x" is true when we use proof by contradiction.

Assume that there exists a positive rational number x for which there is no positive rational number y such that y < x.

Let's consider the set of all positive rational numbers less than or equal to x

S = {y ∈ Q | y ≤ x}

Since there is no positive rational number y such that y < x, the set S must be non-empty, because if S was empty, then x would not have any rational number less than or equal to it.

Let y be the maximum element of the set S. Since y is the maximum element of S, we have y ≤ x, and for any other element z ∈ S, we have z ≤ y.

Since y is rational and y < x, there must exist a positive rational number z such that y < z < x. But z cannot be an element of S, because if z ∈ S, then z would be greater than y, contradicting the fact that y is the maximum element of S. This contradicts our initial assumption that there exists a positive rational number x for which there is no positive rational number y such that y < x.

Therefore, the statement "For every positive x ∈ Q, there is a positive y ∈ Q for which y < x" is true.

The correct answer is option a. $7,594.46.

To calculate the amount you would reduce the amount you owe in the first year, we can use the formula for the equal installment of a loan. The formula is:

Installment = Principal / Number of Installments + (Principal - Total Repaid) * Interest Rate

In this case, the principal is $45,000, the number of installments is 5, and the interest rate is 8.5%.

Let's calculate the amount you would reduce the amount you owe in the first year:

Installment = $45,000 / 5 + ($45,000 - $0) * 0.085Installment = $9,000 + $3,825

Installment = $12,825

The expected number of boxes to be produced is given as 3,000 boxes. So, the correct answer is 0.3, indicating that the takt time in minutes is 0.3 minutes.

The production line operates for two eight-hour shifts each day, which means there are 16 hours of production time available. Since there are 60 minutes in an hour, the total available time in minutes would be 16 hours multiplied by 60 minutes, which equals 960 minutes.

The expected number of boxes to be produced is given as 3,000 boxes.

To calculate the takt time in minutes, we divide the total available time (960 minutes) by the expected number of boxes (3,000 boxes):

\(Takt time = Total available time / Expected number of boxes\)

\(Takt time = 960 / 3,000\)

all values of x that satisfy the inequality f(x)>0 are x < 2 or x > 6.we can solve this by using parabola equation

what is parabola ?

A parabola is a type of conic section, which is a curve that is formed by the intersection of a plane and a cone. In particular, a parabola is the set of all points in a plane that are equidistant to a fixed point (called the focus) and a fixed line

In the given question,

Since the vertex of the parabola is (4,-8), the equation of the parabola can be written in vertex form as:

f(x) = a(x-4)² - 8

where 'a' is a constant that determines the shape and orientation of the parabola.

To find the value of 'a', we can use one of the given points on the x-axis, say (2,0). Substituting x=2 and y=0 in the equation of the parabola, we get:

0 = a(2-4)² - 8

8 = 4a

a = 2

So, the equation of the parabola is:

f(x) = 2(x-4)² - 8

To find all values of x for which f(x)>0, we need to solve the inequality:

2(x-4)² - 8 > 0

Adding 8 to both sides, we get:

2(x-4)² > 8

Dividing both sides by 2, we get:

(x-4)² > 4

Taking the square root of both sides, we get:

x-4 > 2 or x-4 < -2

Simplifying, we get:

x > 6 or x < 2

Therefore, all values of x that satisfy the inequality f(x)>0 are x < 2 or x > 6.
