The percentage of the company she owns after selling its specific parts is equivalent to 41.66%.

In mathematics →

Given is that an entrepreneur sells of 1/2 her company to one buyer and 1/6 to another buyer.

Assume that the amount of company left in percentage is equivalent to {R%}. Let the complete company be represented by 100%. The remaining percent of company after selling half of it can be written as -

100 - {1/2 x 100} = 100 - 50 = 50%.

The remaining percent of company after selling 1/6 of it can be written as -

{R%} = 50 - {1/6 x 50} = 50 - 8.34 = 41.66%
{R%} = 41.66%

Therefore, the percentage of the company she owns after selling its specific parts is equivalent to 41.66%.

Answer:

x = 10 and y = 8

Step-by-step explanation:

100=10x

100= 10y+20

For x, for first equation, we simply solve for x.

10x = 100 => x=100/10

Therefore, x =10

For y, for second equation, simply solve for y.

100= 10y+20 => 10y = 100-20

10y = 80 => y = 8

Given that:

Length, L = 6 inches

Width, W = 2 inches

Height, H = 4 inches

Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as

SA = 2(LW + WH + HL)

SA = 2(6 x 2 + 2 x 4 + 4 x 6)

SA = 2 (12 + 8 + 24)

SA = 2 x 44

SA = 88 square inches

Answer:

\(5\cdot \sqrt{5}\cdot \sqrt[3]{x^4}\cdot y\cdot z^2\) = \(5\cdot \sqrt{5}\cdot x\sqrt[3]{x}\cdot y\cdot z^2\)

Step-by-step explanation:

Let's take the individual terms and convert them to radical form

\(5^{\frac{3}{2}} = (5^3)}^{\frac{1}{2}} = 125^{\frac{1}{2}\)

A term raised to the power 1/2 is nothing but the square root of that term

\(125^{\frac{1}{2}} = \sqrt{125} = \sqrt{25\cdot 5} = \sqrt{25} \sqrt{5} = 5 \sqrt{5}\)

\(x^{\frac{4}{3}} = (x^4)^{\frac{1}{3}} = \sqrt[3]{x^4}\)  since any term raised to 1/3 is the cube root of that term

We can simplify this further by noting \(x^4 = x^3 \cdot x\)'

So \(\sqrt[3]{x^4} = \sqrt[3]{x^3} x = x\sqrt[3]{x}\)

The other exponents are integers

Putting them all together we get

\(5^{\frac{3}{2} }x^{\frac{4}{3}}yz^2 = 5\cdot \sqrt{5}\cdot x\sqrt[3]{x}\cdot y\cdot z^2\)

The lengths of the sides of triangle PQR are PQ = 6, QR = 6 and RP = 2√10

To find the lengths of the sides of triangle PQR, we can use the distance formula between two points in three-dimensional space.

The distance formula is given by:

\(d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2}\)

Let's calculate the lengths of the sides PQ, QR, and RP.

Side PQ:

\(PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2\)

\(= \sqrt{(8 - 4)^2 + (0 - (-2))^2 + (2 - (-2))^2}\\=\sqrt{4^2 + 2^2 + 4^2}\\= \sqrt{16 + 4 + 16}\\= \sqrt{36}\\= 6\)

Side QR:

\(QR = \sqrt{(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2}\\= \sqrt{(10 - 8)^2 + (-4 - 0)^2 + (-2 - 2)^2}\\= \sqrt{2^2 + (-4)^2 + (-4)^2}\\= \sqrt{4 + 16 + 16}\\= \sqrt{36}\\= 6\)

Side RP:

\(RP = \sqrt{(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2}\\= \sqrt{(10 - 4)^2 + (-4 - (-2))^2 + (-2 - (-2))^2}\\= \sqrt{6^2 + (-2)^2 + 0^2}\\= \sqrt{36 + 4 + 0}\\= \sqrt{40}\\= 2\sqrt{10}\)

Therefore, the lengths of the sides of triangle PQR are:

PQ = 6

QR = 6

RP = 2√10

To test the hypothesis that the mean weight of two sheets is equal (μ1 - μ2) against the alternative that it is not, and assuming equal variances, we can use a two-sample t-test. The t-statistic can be calculated using the following formula:

t = (x1 - x2) / (s_p * sqrt(1/n1 + 1/n2))

where:

x1 and x2 are the sample means of the two sheets,

s_p is the pooled standard deviation,

n1 and n2 are the sample sizes.

The pooled standard deviation (s_p) can be calculated using the following formula:

s_p = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

where:

s1 and s2 are the sample standard deviations.

False. Scaling, in the context of graphics, refers to the process of resizing an image or graphic while maintaining its aspect ratio. It involves changing both the vertical and horizontal size of the graphic by the same percentage.

When scaling a graphic, the goal is to resize it proportionally, preserving the original aspect ratio. This means that both the vertical and horizontal dimensions are changed by the same factor or percentage. For example, if an image is scaled by 50%, both its height and width will be reduced by 50% of their original values. This ensures that the graphic maintains its original proportions and does not appear distorted.

Scaling graphics is commonly used in various applications, such as graphic design, image editing, and web development, to resize images without distorting their appearance. It allows for consistent resizing across different devices or platforms while maintaining the integrity of the original graphic.

Step-by-step explanation:

The equation for the line of best fit will be -

y = - 1.74x + 46.6

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the following table tracking Maleia running training program.

Month  Time (minutes)

1                46

2               42

3               40

4               41

5               38

6               36

We can see that the points (1, 46) and (2, 42) will lie on the graph of the line of best fit. Since, the value of [y] is decreasing, so we can easily say that the slope will be negative. So, we can write the equation for the line of best fit as -

y = - 1.74x + c

The nearest point to [y] value is 46.6. So, we can write -

c = 46.6

Therefore, the equation for the line of best fit will be -

y = - 1.74x + 46.6
