Two beetles sit at the top edge of the house roof. The roof has two faces. The first face is such that the horizontal shift by 3 cm along this face means 2 cm shift vertically. Simultaneously the beetles start moving downwards, the first beetle by the first face, the second – by the second face of the roof. First beetle moves twice as fast as the second beetle. Find the altitude of the second beetle above the first beetle when they will be 72 cm apart horizontally, if the second face of the roof
has the same incline as the first face.

Line plot , because a small number of scores are reported individually

What is a line plot?

A line plot is a graph that shows data as points or check marks above a number line, indicating the frequency of each value.

If we need to compare two different groups , a line chart does have one advantage for visualizing frequency distributions

Given data ,

Total number of athletes = 15

The score points of athletes = { 1 , 2 , 3 , 4 , 5 }

The number of athletes = { 1 , 2 , 3 , 4 , 5 }

The best option to plot the line plot because of the data set

The line plot , a data visualization chart that more accurately represents the small data set, is chosen.

And , to begin, unlike a line plot , a histogram involves data ranges or intervals. A line plot uses a dot to represent each observation, whereas a histogram divides the data into intervals, masking the identity of each observation

Furthermore, because line plots are one of the simplest statistical plots, they are better suited to small to moderate-sized data sets. They are more effective than histograms at highlighting clusters and gaps

The F Test statistic is 1.58.

Given data is

Source       SS           df          MS

between   21,000.00       2        6,000.00

within  442,500.00  117        3,782.00

The SStotal is sometimes easier to calculate than SSbetween Since ......

SSwithin +SSbetween = SStotal you can use SStotal to calculate SSbetween.

= 442,500+21,000 =  463,500

In ANOVA, the F test statistic is the  ratio of the between - treatments variance and the within-treatments variance. The value of the F test statistic is 1.58 when the null hypothesis is true , the F test statistics is closer to 1, when the null hypothesis is false, the F test statistic is most likely large in general, you should reject null hypothesis for larger values of the F test statistic.

Hence the answer is the F Test statistic is 1.58.

By Computing the Logarithmic Relation, we calculate that the time between injections is 5.1 hours or 5 hours and 6 minutes.

The given formula is

[tex]D = 5e^{-0.1h}[/tex]

where D is the amount of drug in milligrams in the patient's bloodstream and h is the number of hours after the drug was administered.

So, it is given that D = 3 and we need to evaluate the number of hours it took between the injections,

So, We have,

[tex]D = 5e^{-0.1h}[/tex]

[tex]\frac{D}{5} = e^{-0.1h}[/tex]

Taking Natural log on both sides, we have :

[tex]ln\frac{D}{5} =ln e^{-0.1h}\\\\ln\frac{D}{5} = -0.1h\\[/tex]

We have D = 3, putting it in the formula, we get

[tex]\ln\frac{3}{5} = -0.1h\\\\ln(0.6) = -0.1h\\\\-0.5108 = -0.1 h\\\\h = \frac{0.5108}{0.1} = 5.1[/tex]

Hence, the time between injections is 5.1 hours or 5 hours and 6 minutes.

The solutions of the equations are x = 1 and y = 2

The system of equations are

4x + 3y = 10

-4x + 5y = 6

Here we have to use the elimination method. Eliminate the x term and find the value of y term

Add both equation

3y + 5y = 10 +6

Add the like terms

8y = 16

y = 16 / 8

Divide  the terms

y = 2

Substitute the value of x in the first equation

4x + 3y = 10

4x + 3×2 =  10

Multiply the terms

4x + 6  = 10

4x = 10 - 6

4x = 4

x = 4 / 4

Divide the terms

x = 1

Hence, the solutions of the equations are x = 1 and y = 2

The measure of the Largest angle using the angle sum property of a triangle is: 80°

What is the Angle sum property of a triangle?

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180o, regardless of whether it is acute, obtuse, or right.

One of the most commonly applied properties in geometry is the triangle's angle sum property. Most often, the unknown angles are calculated using this attribute.

In the given figure, we have:

Measure of 1st angle = 64°

Measure of 2nd angle = (2x + 14)°

Measure of 3rd angle = (6x + 14)°

and we know the angle of the property,

using the  angle of property,

64° + (2x + 14)° + (6x + 14)° = 180°

⇒64° + 8x + 14° + 14° = 180°

⇒92°  + 8x = 180°

⇒ 8x = 180° - 92°

⇒8x = 88°

⇒ x = 11°

So,

Measure of 2nd angle = (2x11 + 14)°

Measure of 2nd angle = (36)°

Measure of 3rdangle = (6x11 + 14)°

Measure of 2nd angle = (80)°

Hence,

After solving the linear programming problem, we get the answer as 250.

What is linear programming?

When a linear function is exposed to multiple restrictions, linear programming maximizes or minimizes the function. This method determines the best way to use the resources that are currently available and aids managers in using the process to make decisions about the most efficient use of scarce resources, such as money, time, materials, and machinery. Linear programming has been useful for guiding quantitative decisions in business planning, industrial engineering, and—to a lesser extent—in the social and physical sciences.

If A is located at (3,4) and B is located at (7,6) , then the slope of BC is -2  .

In the question ,

it is given that ,

In the rectangle ABCD , the coordinate of the point A is (3,4) and the coordinate of the point B is (7,6) .

since the sides of the rectangle are at 90° , that means they are perpendicular .

which means AB⊥BC ,

the slope of AB = (6-4)/(7-3)

slope = 2/4

slope = 1/2

Since , AB⊥BC ,

(slope of AB)×(slope of BC) = -1

substituting the values , we get

(1/2)×(slope of BC) = -1

slope of BC = -1/(1/2)

slope of BC = -2 .

Therefore , If A is located at (3,4) and B is located at (7,6) , then the slope of BC is -2  .

The approximate of √59 is 7.7 when rounded off to the nearest tenth place.

Given,  √59

we are asked to determine the approximation without using a square root button.

√59 is a decimal number since it is not a perfect square. Therefore, rather than finding a precise value, we will need to obtain a near approximation of 59 in decimal form.

the square root of the number 59 is:

7.6811

You rounded to the nearest tenths place. The 6 in the tenths place rounds up to 7 because the digit to the right in the hundredths place is 8.

= 7.7

When the digit to the right is 5 or greater we round away from 0.
