1. 4x = 68

x = 68/4

x = 17

Solution :

1) x + 2x + x = 68

>> 4x = 68

>> x = 68 / 4

>> x = 17

2) x + y + 3y = 45

>> x + 4y = 45

>> 17 + 4y = 45

>> 4y = 45 - 17

>> 4y = 28

>> y = 28 / 4

>> y = 7

3) x + y - 4z = -32

>> 17 + 7 - 4z = -32

>> 24 - 4z = -32

>> -4z = -32 - 24

>> -4z = -56

>> z = 56 / 4

>> z = 14

4) x + y + z = ?

>> 17 + 7 + 14

>> 24 + 14

>> 38

5) -x + 8x = 63

>> 7x = 63

>> x = 63 / 7

>> x = 9

6) 4x + 3x - x = 42

>> 7x - x = 42

>> 6x = 42

>> x = 42 / 6

>> x = 7

The required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 +  i√3,  -2 -  i√3

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given equation is,

4x^3 + 16x^2 + 28x = 0

Taking x common we get,

x(4x^2 + 16x + 28) = 0

So, we get

x = 0

And 4x^2 + 16x + 28 = 0

or, x^2 + 4x + 7 = 0

Thus from the above equation is of the form

ax^2 + bx + c = 0

where, a = 1, b = 4 and c = 7

Therefore solution of the above equation is given as,

x = [-b ± √(b^2 - 4ac)] / 2a

Putting the values we get,

x = [-4 ± √(4^2 - 4*1*7)] / 2*1

so, x = [-4 ± √(16 - 28)] / 2

x = [-4 ± √(- 12)] / 2

x = [-4 ± 2√(- 3)] / 2

or, x = [-2 ± √(- 3)]

Since √-1 = i

∴ √(- 3) = i√3

Thus,

x = -2 ±  i√3

So, the required values of x are 0,  -2 +  i√3,  -2 -  i√3.

Thus, the required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 +  i√3,  -2 -  i√3.

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line may be used to compute the slope of any line. The ratio of "vertical change" to "horizontal change" between two separate locations on a line is calculated using the slope of a line formula.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Finding the slope between two separate locations and calculating the slope of a line are related tasks. In general, we require the values of any two separate coordinates of a line in order to determine its slope.

The value of the angle 16°43'27"is approximately 16.724167 degrees.

A plane angle is measured in degrees, with the letter ° typically used to indicate that one full rotation is equal to 360 degrees.

To convert a degree from minutes and seconds to decimal we must know the relation between degree and minutes and seconds.

1 degree=60 minutes.

1 minute = 60 seconds.

The given angle is 16°43'27"

27 seconds = 27 ÷ 60 minutes = 0.45 minutes = 0.45 ÷ 60 degree =0.0075 degree

43 minutes= 43 ÷ 60 degree = 0.71666666..

Total angle in decimal = 16+0.71666666+0.0075 =16.7241666...

You combine like terms:

4x+104=180

Then you subtract on both sides:

4x=76

Then you divide by 4 on both sides:

The value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4

In this question,

we have been given a function f(n) = f(n - 1) - 2

Also, we have been given the value of function f(n) for n = 1

i.e., f(1) = 6

We need to find the value of f(6).

For n = 2,

f(2) = f(2 - 1) - 2

f(2) = f(1) - 2

f(2) = 6 - 2

f(2) = 4

For n = 3,

f(3) = f(3 - 1) - 2

f(3) = f(2) - 2

f(3) = 4 - 2

f(3) = 2

For n = 4,

f(4) = f(4 - 1) - 2

f(4) = f(3) - 2

f(4) = 2 - 2

f(4) = 0

For n = 5,

f(5) = f(5 - 1) - 2

f(5) = f(4) - 2

f(5) = 0 - 2

f(5) = -2

For n = 6,

f(6) = f(6 - 1) - 2

f(6) = f(5) - 2

f(6) = -2 - 2

f(6) = -4

Therefore, the value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4

The median is a better measure of center for the male's data, while the mean is a better for the female's data.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

(a) The IQR of the male's data

From the given male's boxplot, we have the following data elements;

Upper quartile (Q3) = 14

Lower quartile (Q1) = 2

Then the IQR is calculated as:

IQR = Q3 - Q1

So, we have:

IQR = 14 - 2

IQR = 12

Hence, the IQR for the given males' data is 12

(b) The difference between the median values can be calculated as;

Median of male's data = 14

Median of female's data = 9

The difference (d) between the median values is;

d = 14 - 9

d = 5

Hence, the difference between the median values of each data set is 5

(c) The distribution of data

It is found that the median is a better measure of center for the male's data, while the mean is a better measure of center for the female's data.
