This will have additional columns which include

The midpoint

The mid point is gotten by adding the lower class limit and the lower class limit and dividing by two

for instance: 10 + 20 / 2 = 10

The relative frequency

In this column they are in percent and the alue is gotten by first summing up all the frequency then finding the percent of each.

for instance: the total sum of the frequency is 365 so

( 17 / 365 ) *  ( 100 / 1 ) = 4.66%

The cumulative frequency

The cumulative frequency is solved by sequential addition of the frequency

for instance:

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.)

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.

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.

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.

The military drone must ascend 12250 from its position of 3500ft above sea level feet so that it is vertically in the middle of the plane and the submarine.

To solve this problem we need to understand the concept of sea-level. The sea-level is defined as the average height of all water bodies of the earth. Below sea level is effectively taken as negative length and above sea -level is taken as positive length.

Let us consider the drone will have to ascend x feet to be vertically in between the plane and the submarine.

The submarine is 3500 feet below the sea level.

The plane is 35000 feet above the sea level.

Now we know that the drone is at a height of 3500 feet above the sea level.

Total distance between the drone and the ship=35000-(-3500)=38500ft

Middle point of the two=38500/2 = 19250 feet from the plane

Height above sea level for the drone should be=35000-19250=15750 ft

height of the drone=3500ft

The drone should ascend=15750-3500=12250 feet

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)

3(81-4z) +4z =139

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 ...

The solutions to the given quadratic equation 4x² - 4x - 1 = 0 are x = ( 1 - √2 )/2,  ( 1 +√2 )/2.

A quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the equation in the question;

4x² - 4x - 1 = 0

Compared to the standard form ax² + bx + c = 0

Plug these values into the quadratic formula above.

x = (-b±√(b² - 4ac)) / (2a)

x = (-(-4) ± √((-4)² - ( 4 × 4 × -1 ))) / (2 × 8)

x = ( 4 ± √( 16 - ( -16) ) / (8)

x = ( 4 ± √( 16 + 16) ) / (8)

x = ( 4 ± √( 32) ) / (8)

32 can be written as 4²×2

x = ( 4 ± √( 4²×2 ) ) / (8)

x = ( 4 ± 4√2 ) / (8)

x = ( 1 ± √2 ) / 2

x = ( 1 - √2 )/2,  ( 1 +√2 )/2

Therefore, the solutions to the given quadratic equation 4x² - 4x - 1 = 0 are x = ( 1 - √2 )/2,  ( 1 +√2 )/2.

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
