Answer 1

Step-by-step explanation:

If you have a vector that starts at (a,b) and goes to (c,d), then the vector is <c-a, d-b>.

Here, that gives <-9,-12>, meaning the vector should point down to the left.

Additionally, anytime you have a vector <x,y>, you can write it as xi + yj, where i and j are unit vectors, <1,0> and <0,1> respectively.

Here that would be -9i-12j.

The magnitude of a vector <a,b> is equal to \sqrt{a^2+b^2}.

Here that would give you a length of 15.

As for the angle, if you drew a circle centered at the origin, we call 0 degrees the right side, on the x-axis.

You can shift a vector around on a plane and as long as it is parallel to and has the same magnitude as the original, it is the same. So let's put the tail of the vector at (0,0), so that the vector goes from (0,0) to (-9,-12). Now, form a triangle with those two points and the y-axis at (-9,0).

Now, the sin of the angle next to the origin is equal to 12/15, so the angle is arcsin(12/15) which is about 0.9273 radians, or 53.13 degrees. Let's use degrees.

Now, where is this angle? This angle is underneath the x-axis on the left side of the origin. Going from the x-axis on the right side, over the top, to the x-axis on the left side, is 180 degrees. We add 53.13, and get 233.13 degrees. Note that we did this counterclockwise, which you should probably note in your explanation. It is also 180-53.13 = 126.87 degrees clockwise.

In order to find a unit vector (a vector with magnitude 1) in the same direction as the original, just divide by the magnitude, giving us <-9/15, -12/15> or <-3/5, -4/5>. You can verify that the magnitude is equal to 1.

Upon graduation, Natalie had five job offers. The annual salaries for four of the jobs were: $36,000, $45,000, $28,000, and $32,000. The average of the five annual salaries was $38,000. What was the fifth annual salary?

Answers

Answer:

The fifth salary = $49,000

Step-by-step explanation:

Let x be the fifth salary

Total salary = $36,000, +  $45,000 + $28,000 + $32,000 + x

= $141,000 + x

The average of 5 salaries is $38,000

Total = Average x number of elements

= 38000 x 5 = 190,000

Equating the two totals

141,000 + x = 190,000

Subtract 141, 000 from both sides

x = 190,000 - 141, 000

x = $49,000

So the fifth salary = $49,000

Answers

The measurement of the side g in the Δ EFG is 218.38

What is sine rule of triangle?

The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.

Given that, In Δ EFG, f = 400 inches, m ∠ F = 94° and m ∠ G = 33°, we need to find, the length of g (refer to figure attached)

Using the sine rule of the triangle,

f / Sin F = g / Sin G = e / Sin E

400 / Sin 94° = g / Sin 33°

g = 400 / Sin 94° × Sin 33°

g = 218.38

Hence, the measurement of the side g in the Δ EFG is 218.38

Gavin’s gross pay is $3851. his deductions total $756.72. what percent of his gross pay is take-home pay? responses 20% 20% 24% 24% 80% 80% 82%

Answers

Answer:

80%

Step-by-step explanation:

Gross Pay = $3851

Deductions = $756.72

Take-home Pay = $3851 - $756.72 = $3,094.28

Ratio of take-home pay to gross pay = 3,094.28/3851 = 0.8035

As a percentage = 0.8035 x 100 = 80.35%

consider a data set with at least three data values. suppose the highest value is increased by 10 and the lowest is decreased by 10. (a) does the mean change? explain.

Answers

If the highest value is increased by 10 and the lowest is decreased by 10 the mean doesn't change

Let us assume the data set with 10 observations:

{5, 6, 4, 3, 2, 6, 4, 9, 4, 4}.

Arranging data set in ascending order

{2, 3, 4, 4, 4, 4, 5, 6, 6, 9}

Mean of this data = Sum of all observations/Total number of observations

Mean = (2 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 9)/10

Mean = 47/10 = 4.7

Now, Increasing the highest value by 10 and decreasing the lowest value by 10

So, the new data set is {-8, 3, 4, 4, 4, 4, 5, 6, 6, 19}

Mean of this data = -8 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 19/10

Mean = 47/10 = 4.7

Hence, the mean doesn't change.

the standard deviation is used in conjunction with the

Answers

When describing bell-shaped distributions statistically, the standard deviation is utilised along with the mean.

What does the mean actually measure?

While the standard deviation gauges the distribution's spread, the mean gauges the distribution's centre.

What is the purpose of standard deviation?

For the aim of quantifying dispersion, or the variation that takes place in the values of a data set that is taken into consideration, the standard deviation is used. The data points are said to be close to the mean when the standard deviation number is reduced. The opposite will occur when it is higher. In this way, it gauges how widely apart data points are from the mean.

Anything's predicted value is sometimes referred to as a mean. It is the object that serves as the focal point for all data points. The standard deviation determines how widely apart all the data points are from the mean, whereas the mean is the centre of the distribution.

What is the name of standard deviation?

Because it is the square root of the means of the squared errors from the arithmetic average, standard deviation is often referred to as root-mean square deviation. Standard deviation is a word used in economics to indicate how risky an investment is.

What is Temperature?

The physical concept of temperature indicates in numerical form how hot or cold something is.

A thermometer is used to determine temperature.

One variable that makes use of the scale interval is temperature.

Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points and thermometric substances.

The most popular scales are the Celsius scale, sometimes known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), and the Kelvin scale (K), with the latter being mostly used for scientific purposes.

One of the seven base units in the International System of Units is the kelvin (SI). The lowest point on the thermodynamic temperature scale is absolute zero, or zero Kelvin, or 273.15 °C.

Answers

Answer: (3,-6)
x = 3 & y = -6

Explanation:

y = -2x
y = 5x - 21

FINDING X
Since y = -2x we can substitute the y in the second equation with -2x.

-2x = 5x - 21

There is two x’s so you have to get rid of one, in this case 5x, by subtracting it from both sides.

-2x = 5x - 21
-5x -5x
—————
-7x = -21

Then we are going to isolate the x by dividing -7 by both sides.

-7x = -21
—— —— - 7 divided by 7 is 1 so it
-7 -7 would be 1x or x
x = 3

So our x is 3. Now we move on to finding y.

FINDING Y
To do that, we are going to use the first equation.

y = -2x

We are going to plug in the x.

y = -2(3)
y = -6

So our y is -6.

CHECKING
If you want to check it to make sure you have the correct answer you can just plug all of it in to the equation.

y = 5x - 21
-6 = 5(3) - 21
-6 = 15 - 21
-6 = -6

The equation that portrays the correct use of the distance formula is  6.71 = √( ( 11 - 5 )² + ( y₂ - 6 )² )

Which equation is the correct use of the distance formula?

D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

From the diagram;

Point A (5,6)

D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

6.71 = √( ( 11 - 5 )² + ( y₂ - 6 )² )

Of those, only 28,535 received an organ transplant that year. This is a ratio of approximately 1 in 4. This can be expressed mathematically as 28,535/113,000 = 0.25, or one fourth.

Answers

By using the formula for permutation, we can find that there are 2,598,960 possible combinations of 5 cards that can be dealt from a standard deck of 52 cards.

Poker is a popular card game that is played with a standard deck of 52 cards.

A permutation is the arrangement of objects in a specific order. In this case, the objects are the 52 cards in a standard deck, and the order is the 5 cards that are dealt to each player.

To find the number of possible 5-card hands, we can use the formula for permutation:

P(52, 5) = 52! / (52 - 5)!

Where "52!" is the factorial of 52, meaning the product of all positive integers from 1 to 52.

52! / (52 - 5)! = 806,368,039,360 / 47! = 2598960
