Given that the study was conducted using a sample of 513 bolts produced at a single facility when there is no bias resulting from data gathering procedures, broad inferences may then be drawn.

All bolts manufactured by that factory would be covered by the conclusion?

Due to the fact that bolts made in the same factory will follow the results of an analysis of a sample made up of bolts from the same factory. The finding or conclusion would therefore be applicable to all bolts produced in the same factory because the environment for experimentation and production is the same there while it may differ in other factories. Conclusions from the study may not apply to the bolts made by other companies as a result of this bias.

The car has a value of $ 15 500 at the end of the fifth year.

In accordance with the statement, the value of an automobile decreases in time and decreases steadily. A stead decrease means that the value decreases linearly in time, whose formula is shown below:

C' = C + r · t         (1)

Where:

If we know that C = $ 2 600, C' = $ 37 000 and t = 8, then the value of the car at the end of the fifth is:

r = (C' - C) / t

r = (2 600 - 37 000) / 8

r = - 4 300

t = 5

y = 37 000 - 4 300 · 5

y = 15 500

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° .

consider the inner triangle where

a + b + 58° = 180° ( subtract 58° from both sides )

a + b = 122°

consider the outer triangle where

c + d + 63° = 180° ( subtract 63° from both sides )

c + d = 117°

Then

a + b + c + d = 122° + 117° = 239°

D=16(3)

D=16(4)

=64 feet

The distance between third and fourth second=64 feet-48 feet

=16 feet

=========================================================

Explanation:

A = (4,5) is one endpoint

B = (-1, 4) is the midpoint

C = (x,y) is the other endpoint

For now, focus on the x coordinates of each point

A and C have x coordinates of 4 and x respectively

Add them up and divide in half. Set this equal to the x coordinate of B

(4+x)/2 = -1

4+x = 2*(-1)

4+x = -2

x = -2-4

x = -6 which is the x coordinate of point C

Repeat this same idea for the y coordinates

(5+y)/2 = 4

5+y = 2*4

5+y = 8

y = 8-5

y = 3 which is the y coordinate of point C

Therefore, point C is located at (-6, 3)

--------------------------

To verify the answer, you can use the distance formula to calculate the following segment lengths: AB and BC

You should find that AB = BC. This is because the midpoint splits segment AC into two smaller equal pieces.

Another way to verify the answer is to use the midpoint formula on points A(4,5) and C(-6,3). The result of using this formula should be B(-1,4) mentioned earlier.

Answer: 45

Step-by-step explanation:

The LCM of 5 and 9 is 45. To find the least common multiple of 5 and 9, we need to find the multiples of 5 and 9 (multiples of 5 = 5, 10, 15, 20 . . . . 45; multiples of 9 = 9, 18, 27, 36 . . . . 45) and choose the smallest multiple that is exactly divisible by 5 and 9, i.e., 45.

The length of AC is 6.228 cm.

Here the angle of the triangle ∡ABC is 40°, AB = BC = 9.

We have to find the length of AC which is opposite to ∡B.

Let AB = BC = x , AC = c

From the cosine formula, we know that

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab cos α

Here c is the length of the side opposite to the angle α, and a, b is the side adjacent to the angle α.

So from the cosine formula we have

[tex]c^{2}[/tex] = [tex]x^{2}[/tex] + [tex]x^{2}[/tex] -2[tex]x^{2}[/tex]cos α

[tex]c^{2}[/tex] = 2[tex]x^{2}[/tex] - 2[tex]x^{2}[/tex] cos 40°

   = 2[tex]x^{2}[/tex](1- cos 40°)

   = 2 ×[tex]9^{2}[/tex] ( 1 - 0.76)

    = 2 × 81 × 0.24

c = 2 × 9 × 0.2×√3

  =3.6 × 1.73

Therefore the length of the side AC is 6.228cm.

This investigation's goal is to demonstrate how quickly and easily we can determine the diameter of the sun using basic geometry.

The cards must remain parallel and separated by a predetermined amount. Then, a tiny hole must be cut on one card so that sunlight can pass through and create the sun's picture on the other card. We base the formula described above on the diameter of this photograph of the sun. The diameter of the sun's picture on the card is now measured because we can choose the distance between the cards, and we already know that the sun is nearly 150 million kilometers away from the earth. i.. e. Since three of the values are known, we can use the technique above to determine the fourth unknown quantity and measure the diameter.

The total amount of gallons of gasoline expended by all the automobile drivers in the United States is 9 × (10)10 gallons. It is obtained using the basic concepts of word problems based on multiplication and division.

What are word problems?

Word problems are defined as mathematical problems that are completely expressed in the notation of words or language rather than numbers. Word problems can simply be based on addition, subtraction, multiplication, division, percentage, etc.

Calculation of the total amount of gasoline consumed in the US in units of gallon

According to the word problem, the total number of people in the US is  3 × (10)8

Number of people having cars = ½ × 3 × (10)8

                                               = 1.5 × (10)8

Each car drives an average of 12000 miles per hour, so the total distance travelled by one car is 12000 miles

The distance covered by all the cars = 1.5 × (10)8 × 12000

= 1.8 × (10)12 miles

20 miles is covered in 1 gallon of gasoline

1 mile is covered in 1/20 gallon of gasoline

So, 1.8 × (10)12 miles will be covered in 1.8 × (10)12 × (1/20)

= 9 × (10)10 gallons

Hence, the gallons of gasoline required is 9 × (10)10 gallons.
