Answer:

x=3

Step-by-step explanation:

Answer: 42.5 degrees

Step-by-step explanation:

Sin= Opposite/hypotenuse or Height/ String length

when we don't know the angle we use sin^-1(OPP/HYP) so sin^-1(25/37)= 42.51

To write slope intercept form from a point, you take the 2 and covert it to 2/1, or rise/run form. Then you find the y-intercept. Now listen, this is very complicated. Ready? It's the y-coordinate. 4. Veery complicated.

So y=2/1+4

7a.C

7b.Angle AED

7c.Angle 8

7d. Angle 6 and 8

Step-by-step explanation:

6a. The labeled angles are vertical angles so we set them equal to each other.

[tex]7x - 8 = 6x + 11[/tex]

[tex]7x = 6x + 19[/tex]

[tex]x = 19[/tex]

7a.Angle 11 is near Point C so Point C is the vertex.

7b. Angle 5 vertex is E so we can use any 3 points as an angle as long as E is in the middle example, and the angles are on the left side so we can use

[tex]aed[/tex]

Write the angle sign as well.

7c. Angle 6 is vertical from Angle 8.

7d. Angle 7 and 6 form a linear pair and since Angle 6=Angle 8, Angle 7 and 8 form a linear pair as well.

Answer:

Primary Data Secondary Data

Reliability and Suitability

Primary data are more reliable and suitable for the enquiry because it is collected for a particular purpose. It is less reliable and less suitable as someone else has collected the data which may not perfectly match our purpose.

Answer:

(2) Time-consuming This method is time-consuming as investigator personally visits the various places and meet different people to collect information.

3) Secondary data is usually gathered from the published (printed) sources. A few major sources of published information are mentioned below: Published articles of local bodies and Central and State Governments. Statistical synopses, census records and other reports issued by different departments of the Government.

4) National Sample Survey Organisation (NSSO) is the largest and a very prominent agency of India working for the collection of data on various economic variables such as education,health,literacy rates, etc. ... Census of India is responsible for the collection of data related to different demographic characteristics.

5)The investigator must ensure that the data are suitable for the purpose of enquiry. 2. Inadequate Data: Adequacy of the data is to be judged in the light of the requirements of the survey as well as the geographical area covered by the available data.

6)The principles to be followed while drafting questionnaire are: 1) The questionnaire must not contain many questions, as greater the questions, lesser will be the possibility of reply from respondents. 2) The questions should be brief and clear. 3) The questions should be arranged in a logical order.

7) Reliable and Accurate: Results based on census method are accurate and highly reliable. This is because each and every item of the population is studied. Less Biased: Results based on census method are less biased. It is because of the absence of investigator's discretion regarding the selection of sample items.

8) It allows us to get near-accurate results in much lesser time. When you use proper methods, you are likely to achieve higher level of accuracy by using sampling than without using sampling in some cases due to reduction in monotony, data handling issues etc.

Step-by-step explanation:

this is the correct answer you want

please follow me ☺️.

1. Primary data is much more reliable than secondary data. This is because primary data gives up-to-date information about a topic and is collected by doing research, avoiding the use of secondary sources which may include false and not up-to-date information.

2. The most common methods of collecting primary data are interviews, field observations, self-administered surveys, and experiments.

The experimental method:

merits:

-the researcher can have control over variables

-gains insight into methods of instruction

-can be used to determine what's best for the population

demerits:

-sample may not be representative

-human response can be difficult to measure

-subject to human error

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

5. Some precautions that should be considered when using secondary data are:

Reliable agency:

-must ensure that the agency that has published the data should be reliable

Method of collecting data used:

-The investigator should also be aware of the method that was used in collecting the data

-Sampling method may be biased depending upon the mode of selection of samples.

-All these should be ascertained before making use of the secondary data.

Suitability for the purpose of an enquiry:

-The Investigator must ensure that the data are suitable for the purpose of the present enquiry.

-The suitability of the data is determined by investigating the nature, objectives, time of collection, etc. of the secondary data.

Adequacy and accuracy to avoid the impact of bias:

-It is necessary to use adequate data to avoid biases and prejudices leading to incorrect conclusions.

Answer:

C

Step-by-step explanation:

Hello There!

The height of the water starts at 3 feet and its receding at a rate of .75 feet an hour

receding means to move farther away from previous position

so the equation would be

3-.75t

or

-.75t + 3

So we can conclude that the answer is C

It is increasing by 11% for each application.

Step-by-step explanation:

Answer: Si fuera de los que solo fuman sería del 43,5% si solo de los que lo beben sería del 20,5% si fueran los dos sería del 59%.

Step-by-step explanation:

The percentage of the population smokes or drinks is 52%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We are given that;

The drink is half, third and quarter of the percentage

The sum of these percentages must be 100%, so we can write an equation:

x + (1/2)x + (1/3)x + (1/4)x = 100

To solve for x, we need to simplify and isolate x. We can do this by multiplying both sides by 12, the least common multiple of 2, 3, and 4:

12x + 6x + 4x + 3x = 1200

25x = 1200

x = 1200/25

x = 48

This means that 48% of the population neither smokes nor drinks. Therefore, the percentage of the population that smokes or drinks is:

(1/2)x + (1/3)x + (1/4)x

= (1/2)(48) + (1/3)(48) + (1/4)(48)

= 24 + 16 + 12

= 52

Therefore, the percentage answer will be 52%.

Answer: 10.24

Step-by-step explanation:

2.56/1/4 is the same as 2.56*4/1 or 2.56*4= 10.24

Answer:

[tex]Volume = 960in^3[/tex]

Step-by-step explanation:

Given

Empty Tank

[tex]Length = 24in; Width=10in; Height = 12in[/tex]

When filled with water, the height is:

[tex]Height = 8in[/tex]

Required

Determine how many more cubic inches needed

First, we calculate the difference between the height of the tank and the height of the water.

[tex]H = 12in - 8in[/tex]

[tex]H = 4in[/tex]

The volume of water to full the tank is then calculated as:

[tex]Volume = Length * Width * H[/tex]

[tex]Volume = 24in * 10in * 4in[/tex]

[tex]Volume = 960in^3[/tex]

Answer:

Formula for volume = length (L) × width (W) × height (H)

Volume of the stone = 1,440 cm³

Step-by-step explanation:

✔️Formula for the rectangular tank = L*W*H

✔️Volume of the stone = volume of the tank with the stone - volume of the tank without the stone

✔️Volume of the tank with the stone:

L = 30 cm, W = 24 cm, H = 8 cm (height of water when the stone was in the tank)

Volume of the tank with the stone = 30*24*8 = 5,760 cm³

✔️Volume of the tank without the stone:

L = 30 cm, W = 24 cm, H = 6 cm (height of water when the stone was pulled out)

Volume of the tank with the stone = 30*24*6 = 4,320 cm³

✅Volume of the stone = 5,760 - 4,320 = 1,440 cm³
