help pleaseeeee, I’ve been struggling with this a lot lately

Answer: x=-5

Step-by-step explanation:

You would have to do the inverse to “undo” the equation.

So first you would do -7-3=-10

Then you would do -10/2=-5 to find x

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:

[tex]Area= 36g^6h^{10}[/tex]

Step-by-step explanation:

Given

[tex]Length = 6g^3h^5[/tex]

Required

Determine the area as a monomial

This is calculated as:

[tex]Area = Length * Length[/tex]

[tex]Area= 6g^3h^5*6g^3h^5[/tex]

This can be rewritten as:

[tex]Area= 6*6*g^3*g^3*h^5*h^5[/tex]

Apply law of indices

[tex]Area= 36*g^6*h^{10}[/tex]

[tex]Area= 36g^6h^{10}[/tex]

Answer:

aₙ = 207+9*(n-1)

Step-by-step explanation:

a1 = 207+9*(1-1) = 207

a2 = 207+9*(2-1) = 216

a3 = 207+9*(3-1) = 225

....

aₙ = 207+9*(n-1)

Answer:

x=61

2x+3 = 125

x-6 = 55

Step-by-step explanation:

The two angles shown form a straight line so they add to 180

2x+3 + x-6 = 180

Combine line terms

3x-3 =180

Add 3 to each side

3x-3+3 =180+3

3x=183

Divide each side by 3

3x/3 =183/3

x =61

The angle on the left is 2x+3

2x+3 = 2*61+3 = 122+3 = 125

The angle on the right is x-6 = 61-6 = 55

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

Answer:

B. -1

Step-by-step explanation:

-1

According to the slope formula:

Slope = (y2 - y1)/(x2 - x1)

y2 = 6.1

y1 = 3.1

x2 = -5.5

x1 = -2.5

Therefore:

6.1-3.1/-5.5--2.5

Since negative negative is positive you are left with:

3/-3

Therefore the answer is -1.

Answer:

x= 15.4

Step-by-step explanation:

tanx = opp/adj

tan52° = x/12

x= tan52° * 12

x= 15.359

round -> 15.4

:

First calculate yearly interest

500 x 0.015 = 7.5

7.5 x 3(for 3 years) = 22.5

Then add them together!

500 + 22.5 = 522.5

Given:

The figure of a right angle triangle.

To find:

The value of x to the nearest hundredth.

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

Using the above trigonometric ratio for the given triangle, we get

[tex]\cos 46^\circ=\dfrac{x}{8}[/tex]

[tex]0.6947=\dfrac{x}{8}[/tex]

[tex]0.6947\times 8=x[/tex]

[tex]5.5576=x[/tex]

Approximate the value to the nearest hundredth.

[tex]x\approx 5.56[/tex]

Therefore, the value of x is 5.56 units.

Answer:

45degrees, 79egrees and 56degrees

Step-by-step explanation:

Complete question:

The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is  11 more than the measure of the smallest angle. Find all three measures .

Let the smallest angle be x

Let the largest angle be y

Let the third angle be z

Since the sum of angle in the triangle is 180, then x+y+z = 180 .. 1

If the measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle, this is expressed as;

x = y - 34

y = x + 34 ..... 2

If the measure of the third angle is  11 more than the measure of the smallest angle, this is expressed as;

z = x +  11 .... 3

Substitute 2 and 3 into 1;

x + (x+34) + (x+11) = 180

x+x+x+45 = 180

3x+45 = 180

3x = 180 - 45

3x = 135

x = 135/3

x = 45 degrees

From 2;

y = x+34

y = 45 + 34

y =79degrees

From3;

z = x+11

z = 45 + 11

z = 56degrees

Hence the measure of the angles are 45degrees, 79egrees and 56degrees
