The percent of total inventory is Apple, rounded to the nearest tenth of a percent is 15.0%

How do we determine the percentage of claims in Apple?

Out of the total claims of 4,280 items in inventory, the number of claims in Apple is determined as the total claims minus the number of claims attributable to IBM, such that the percentage of total inventory in Apple is computed as the number Apple's claims divided by total claims

number of claims in Apple=total claims-number of claims in IBM

total claims=4,280

number of claims in IBM=3636

number of claims in Apple=4280-3636

number of claims in Apple=644

% of claims in Apple=number of claims in Apple/total claims

% of claims in Apple=644/4280

% of claims in Apple=15.0%(rounded to 1 decimal place as shown in the options provided)

The will have to work for 3 weeks in order to save money for down payment of car.

Unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given in the question is a story of john works at the mall, 20 hours a week and makes $8.50 an hour. He is saving for a car and needs a down payment of $500.

Assume that he has to work 'x' number of weeks for down payment.

For 1 hour, John earns → $8.50

Number of hours he work in the mall per week → 20 hours

Amount of money collected in one week → $8.50 x 20 = $170

Money needed for down payment → $500

In 1 week, John earns → $170

So, he earns $1 in → 1 / 170 weeks

Therefore, he will earn $500 in →

(1 / 170) x 500 = 2.94 = 3 weeks (approx.)

Therefore, he will have to work for 3 weeks in order to save money for down payment of car.

Answer:

Median

Step-by-step explanation:

i think median would be better than mean. This is because with mean, your adding it together then dividing it(by 3 in this case), making the end number higher. tou dont want a higher number in this case.

ex: your numbers are 50, 55,and 90

median = 55 (as it's the middle number)

mean = 65 ( 90+ 55+ 50 / 3)

so median is the lower number, meaning it would be better in this** case.

Transformation of Reflect image over the y axis for this equation (x ,y)->(x +6,y -3)  is  (3, -1)

Reflecting point (-6,1) on y = x

gives (1, -6)

Translating, (1, -6) by 2,5 is

(1 + 2, - 6 + 5) = (3, - 1)

Therefore, reflect image over the y axis translate by rule (x ,y)->(x +6,y -3) is (3, - 1)

transformation :A function, f,  itself is called the transformation, i.e., f: X → X. After the transformation the pre-image X becomes the image X. This transformation can be any part or the mixture of operations such as translation, reflection, rotation and dilation. The translation is working a function in a particular direction, rotation is rotate the function to a point, reflection is the mirror image of the function, and dilation is the ascend of a function.

Translation, rotation, reflection, and dilation are the four most prevalent types of transformations. From the transformation, we have a rotation about any point, reflection over any line, and translation along any angle. The picture is congruent to its pre-image in these stiff transformations.. They are also called as isometric transformations. Dilation is performed at about any point of angle and it is non-isometric.

Rules for Transformations

Consider a function f(x). On a coordinate grid, we use the x-axis and y-axis to check the movement. Here are the rules for transformations of function that could be applied to the all graphs of functions. Transformations can be shown algebraically and graphically. Transformations are commonly found in algebraic functions. We can use the formula of transformations in graphical functions to obtain the graph just by transforming the fundamental or the parent function, and thereby move the graph around, rather than tabulating the coordinate values. We can visualize and learn algebraic equations with the aid of transformations.

Formula of Transformations

Let us consider the graph f(x) = [tex]x^{2}[/tex]

Suppose we have need to graph f(x) = [tex]x^{2}[/tex] -3, we shift the vertex 3 units down.

Suppose we have need to graph f(x) = 3 [tex]x^{2}[/tex]+ 2, we shift the vertex two units above and extend vertically by 3  factor

Suppose we have need to graph f(x) = 2(x-1)^2, we shift the vertex one unit to the right and extend vertically by 2  factor

Thus, we know the formula of transformations as

f(x) =a(bx-h) n + k

where k is the vertical shift,

h is the horizontal shift,

a is the vertical stretch and

b is the horizontal stretch

Step-by-step explanation:

The value of number 3[tex]\sqrt{-512}[/tex]  as complex number is equal to 67.88i.

Given that the number is 3[tex]\sqrt{-512}[/tex].

We are required to find the value of the given number.

We have to first find out the square root of 512. Since we cannot find the square root of a negative number so we have to assume it as complex number and we will multiply the resultant number with i.

A complex number is basically an element of a number system that extends the real numbers with a specific element denoted i called the imaginary unit and satisfying the equation i² = −1 every complex number can be expressed in the form a + bi where a and b are real numbers.

3[tex]\sqrt{-512}[/tex] =3*22.627

=67.88i

It is not an integer and we cannot solve it further.

Hence the value of 3[tex]\sqrt{-512}[/tex] as an complex number is equal to 67.88i.

To make a profit Kelsey must make and sell more than 49  additional pendants

in this given sum we need to find how many additional pendents kelsey need to make and sell to make profit .  The information that are give in the sum

she has to pay $200 for the rent

materials for each pendant is $ 7.8 .

for 10 pendants  the total will be 10*7.8 = $78

Therefore she will spend a total of $(78 +200) = $278

So to make a profit the amount of pendants kelsey make multiply it by 13.50 should be greater than the totall amount she spend in making 10 pendants $278 added to the number  of pendants she makes multiply by 7.8 that is the total cost

let the no. of pendants she need to make be x

we can write then above explanation as

13.50x >278 + 7.8x

=> 13.5x - 7.8x > 278 +7.8x - 7.8x      [subtracting 7.8x on both side]

=> 5.7x > 278

=> x > 278/5.7 = 48.77 = 49 (approx.)

The circumference of the circle with radius 7 and value of pie 3, using the formula C= 2pie r is 42 unit.

Circumference of this circle using 3 for TT and 7 as radius.

The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.

Circumference of circle = π x Diameter of circle.

You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Here, π = 3, r = 7,

So C = 2*7*3 = 42 units.

The TIME function is included as part of Excel's Date and Time features. With the assistance of TIME, we are able to create a time by employing various components for the hours, minutes, and seconds.

While conducting financial analysis, it's possible that we'll need to date a report. Under these conditions, the TIME function may be used to convert a text string into a format that presents the time as a decimal representation of the seconds, minutes, and hours.

Additionally, the function's capabilities include the ability to merge several values into a single time value.

formula= TIME (hour, minute, second)

distance = rate X time

D = RT

T = D/R

720 feet in a minute is equal to 12 feet per second.

480 feet per minute is equal to 8 feet per second.

The number of minutes to go to the flowerbed plus 14 minutes plus the number of minutes to get back to the hive equals 19 minutes.

(D/R) + 14 + (D/R) = 19

(D/R) + 14 + (D/R) = 19

In conclusion, The calculation that we may use to get the distance from the flowerbed to the hive is (D/720 ) plus 14 plus (D/480), which is 19.

(D/720 ) + (D/480) = 5

(D(1200)(480))/1200 + (D(720 )(480))/960 = 5(1200)960

480D + 1200D = 5(720 )480

Answer: The value of RIG is 59 degrees and the value of ZIM is 31    degrees.

Given: Lines AM,ZG, RI are parallel

angle RIM = 90 degree and lines AM,ZG and RI intersect at point I.

Concept: All angles on the same line make an angle of 180 degree.

Since all angles on a line make an angle sum of 180 degree

So using the above property of straight lines,

Angle RIA + angle RIG + angle GIM = 180 degree

90 + 4z+7 +x+2 = 180

4z+x = 81  ----- (1)

Angle AIZ + angle AIR + angle RIG = 180 degree

3x-56 + 90 + 4z+7=180

3x +4z =139 ----- (2)

  (i)  (x√x)/3 -(√x)/2

  (ii)  f(x) = x³/27 +3x -5

Step-by-step explanation:

You want the value of the integral in each case. One integral is indefinite, the other has conditions specified.

In each case, the power rule applies:

  [tex]\displaystyle \int{x^n}\,dx=\dfrac{x^{n+1}}{n+1}[/tex]

The integral can be rewritten as the sum of two integrals involving half powers.

  [tex]\displaystyle \int{\dfrac{2x-1}{4\sqrt{x}}}\,dx=\dfrac{1}{2}\int{x^{\frac{1}{2}}}\,dx-\dfrac{1}{4}\int{x^{-\frac{1}{2}}}\,dx=\dfrac{x^{\frac{3}{2}}}{2\left(\dfrac{3}{2}\right)}-\dfrac{x^{\frac{1}{2}}}{4\left(\dfrac{1}{2}\right)}\\\\=\boxed{\dfrac{1}{3}x\sqrt{x}-\dfrac{1}{2}\sqrt{x}}[/tex]

You are given the derivative and three conditions:

Together with the integral, the conditions give rise to three equations in the three unknown coefficients.

  [tex]\displaystyle f(x) = \int{ax^2+b}\,dx=\dfrac{a}{3}x^3+bx+c[/tex]

Then the equations we can write for a, b, c are ...

  f'(3) = 4   ⇒   a(3²) +b = 4

  f(3) = 5   ⇒   (a/3)(3³) +b(3) +c = 5

  f(0) = -5   ⇒   a(0³) +b(0) +c = -5

The last equation gives the value of c = -5, so the remaining equations become ...

  9a +b = 4

  9a +3b = 10

Subtracting the first from the second, we have ...

  (9a +3b) -(9a +b) = (10) -(4)

  2b = 6

  b = 3

Using this in the first equation, we find 'a' to be ...

  9a +3 = 4

  a = 1/9

Then f(x) is ...
