While traveling to his grandmothers for Christmas, George had been asleep for 50% of the entire journey and this distance is found by reviewing the information given to us.

The length of the entire journey taken to get from one point to another is the distance travelled. Travel distance is not a vector. It has no orientation.

In this question,

Let us take that George had been asleep for x distance.

Then according to question, we can form the equation

3/4 = 1/2x + x

3/4 = 3x/2

x = 1/2

so, the total distance travelled is 50% of the entire journey.

Displacement is the straight path between the initial and final points, whereas distance travelled is the actual length the body covers.

The International System of Units defines a meter as the distance unit.

How can velocity be used to calculate distance travelled?

Finding the area under the velocity, in particular when velocity is positive on an interval, allows us to determine the total distance travelled.

Answer:

Yes.

Step-by-step explanation:

Divide 430/17 and you get around 25, signifying the correct answer is right in the middle of Hailey's estimation.

The non real roots of the polynomial x³ – 7x² + 15x – 25 = 0 are; 1 + 2i, 1 – 2i

Non real roots are simply imaginary roots.

We are told that the real roots of the equation  x³ – 7x² + 15x – 25 = 0 is 5.

Now, it means that (x - 5) is a factor of the given polynomial. Thus, we can factorize the polynomial as;

(x - 5)(x² - 2x + 5) = 0

Now, to find the non - real roots, we will use quadratic formula on (x² - 2x + 5) to get;

x = [-(-2) ± √((-2)² - (4 * 1 * 5))]/2(1)

x = (2 ± √(-16))/2

x = 1 ± 2i

A list of fixed fees for services recorded on the encounter form is called the Superbills.

The purpose of encounter forms, often referred to as super bills, is to "document services performed by recording the diagnostic and procedure codes, which serve as the foundation for billing and receipt of payment for services." Every time a patient or customer receives a service, the provider records that service, often into medical claims software that may automate much of the subsequent procedure.

This technique entails coding (procedure codes and, if necessary, diagnostic codes), billing/invoicing, and/or transmission to the patient's or client's insurance provider. For the client's health and treatment plans as well as for proper billing, it is crucial to make sure that the appropriate information is documented. This is why encounter forms are such a crucial component of healthcare.

Equation of the line passing through the point of (-20, 4) and perpendicular to the line [(2x + 5y) = 10] will be [2y = (5x + 108)].

As per the question statement, a line passes through the point of (-20, 4) and is perpendicular to the line [(2x + 5y) = 10].

We are required to determine the equation of the above-mentioned line.

To solve this question, we need to know about the formula to express the point-slope form of a line, which goes as, [(y - y₁) = m(x - x₁)],

where (x₁, y₁) is a point through which the line passes, and "m" is the slope of the line.

Also, we need to know about the mathematical fact that, the product of the slopes of two perpendicular lines equate to (-1), i.e., if (m₁ and m₂) are the slopes of two perpendicular lines, then [(m₁ * m₂) = (-1)].

Converting [(2x + 5y) = 10] into the point-slope form of line, we get,

(2x + 5y) = 10

or, [5y = {(-2x) + 10}]

or, [y = {(-2/5)x + 2}]

Therefore, Slope of the line [(2x + 5y) = 10] is (-2/5).

Hence, slope of the line perpendicular to [(2x + 5y) = 10] is [-1/(-2/5)], i.e.,

Slope of the line perpendicular to [(2x + 5y) = 10] is (5/2).

Now, using [m = (5/2)] and (x₁, y₁) as (-20, 4), equation of the line will be

[(y - 4) = (5/2){x - (-20)}]

or, [(y - 4) = (5/2)(x + 20)]

or, [(y - 4) = (5/2x) + 50]

or, [2(y - 4) = 5x + 100]

or, [(2y - 8) = (5x + 100)]

or, [2y = (5x + 108)]

Given the equation that

If the gondola is filled with 25 randomly selected skiers, the probability that it will be overloaded is; 50%

The formula to find the maximum mean weight of passengers is;

Maximum mean weight = Load limit ÷ number of passengers

We are given;

Load limit = 5000 lb

Maximum number of passengers = 25

Thus;

Maximum mean weight of passengers = 5000 ÷ 25 = 200lb

Let us find the z-score:

z = (max value - mean) / st. dev

z = (200 - 200)/40

z  = 0

Step-by-step explanation:

F(x) is bascially the y

the absolute value means any numbers that you use for x when substituted into x-2 will always be a positive number even if x-2 is negative as with any number 3 or greater, or any number -3 or less.  

for the values that are 0, 1, 2, 3, 4 or 0, -1, -2  the answer for f(x) will be a negative number.  All other numbers positive or negative for x will result in a positive answer.  

So you need to graph your line with an arrow on each end to show it goes to infinity.  in your chart you choose a number for x, and the f(x) number (which is equivalent to the y number for purposes of graphing.

I cannot draw on her a graph for you because I don't have that ability without an app for that.  

here are some sample points for your chart.  THe first number in each parenthesis is x and the second is f(x)

(-1, -2),  (-2, -1), (0, -3), (-3, 0), (1, -4), (2, -5), (3-4), (4,-3), (5-2), (6, -1)  All other numbers positive or negative for x will result in f(x) being positive.

You only need two sets of points to put on the graph to draw the line through.  

So negative values for f(x) can only be -1, -2, -3, -4, -5.   x can include all negative numbers through infinity.

Positive will include all positive numbers through infinity for x  and f(x).

F(x) cannot decrease beyond -5.   x can decrease all numbers  through infinity.

The means are the same and the standard deviations are different.

There are two lists given for which the means and the standard deviations need to be compared. So we first find the mean and standard deviation of each list one-by-one using the formulas,

Mean = (1/n)∑x

Variance = [(1/n)∑x²]- mean²

Standard deviation = √variance

List A  

x:  1      2     3      4     5      6

x²: 1      4     9    16    25     36

n = 6

Mean = (1/6)[1+2+3+4+5+6] = 21/6 = 3.5

Variance = 1/6[1+4+9+16+25+36] - 3.5² = 15.167-12.25 = 2.917

Standard deviation = √2.917 = 1.71

List B

x:  2    3    3     4     4    5

x²: 4    9    9    16   16   25

Mean = 1/6(2+3+3+4+4+5) = 21/6 = 3.5

Variance = 1/6(4+9+9+16+16+25)-3.5² = 13.167 - 12.25 = 0.917

Standard deviation = √0.917 = 0.9576

Hence the means are the same and the standard deviations are different.
