Answer:
X + 4 = 48
Step-by-step explanation:
Before hat purchase :
Michael has $68
Craig has $24 less than Michael;
Hence, Craig = $68 - $24 = $44
Michael purchased hat worth, $20
x = amount Craig has after Michael purchase hat:
x = Amount Michael has - $24
Amount Michael has after hat purchase = $68 - $20 = $48
x + 4 = 44 + 4
X + 4 = 48
Slope intercept form of (2,4) slope is 2
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

please answer me fast
please attempt the question not text me any thing for points
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.

Find the slope of the line that passes through the pair of points.
(–5.5, 6.1), (–2.5, 3.1)
A. [tex]\frac{3}{8}[/tex]
B. –1
C. 1
D. [tex]-\frac{3}{8}[/tex]
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.
Cake has a circumference of 20.41 inches what is the area of the cake used 3.14 approximate round to the nearest 10th
Answer:
33.2 inches²
Step-by-step explanation:
Steps to derive the answer
we are going to first determine the radius from the circumference we would calculate the areaCircumference of a circle = 2nr
n = 3.14
r = radius
20.41 = 2x 3.14 x r
Divide both sides by (2 x 3.14)
r = 3.25 inches
Area of a circle = nr²
3.14 x 3.25² = 33.2 inches²

Step-by-step explanation:
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 more than the measure of the smallest angle. Find all three measures .
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

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.

For which value of x must the square root
97x
be further simplified
Question:
For which value of x must the expression √97x be further simplified?
A. 5 B. 10 C. 15 D. 20
Answer:
[tex]D.[/tex] [tex]x = 20[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{97x[/tex]
Required
For what value of x can it be simplified
From the list of options, only (D) is correct
D. 20
Substitute 20 for x in [tex]\sqrt{97x[/tex]
[tex]\sqrt{97 x} = \sqrt{97 * 20}[/tex]
Express 20 as 4 * 5
[tex]\sqrt{97 x} = \sqrt{97 * 4 * 5}[/tex]
Reorder
[tex]\sqrt{97 x} = \sqrt{4 *97 * 5}[/tex]
Split
[tex]\sqrt{97 x} = \sqrt{4} *\sqrt{97 * 5}[/tex]
[tex]\sqrt{97 x} = 2*\sqrt{97 * 5}[/tex]
[tex]\sqrt{97 x} = 2*\sqrt{485}[/tex]
[tex]\sqrt{97 x} = 2\sqrt{485}[/tex]
With other values of x, the given expression can not be simplified.
Hence:
[tex]x = 20[/tex]
