Answer:
affect the validity and the bias
Step-by-step explanation:
Research bias, which can also be referred to as experimenter bias, is a deliberate attempt by a researcher who is carrying out an experiment to influence the research results, so that he/she can obtain a predetermined outcome. He can do this by deliberately tailoring the method of data collection to such methods as suit the achievement of such predetermined outcome. This is called data collection bias in research. Hence the process of data collection affects the bias of a study.
A study is valid if it truly achieves its aim. Validity refers to how correct or incorrect the results of a scientific study is. Validity of a study often depends on the method of data collection. If the correct method of data collection was used during the study, then its results will be valid.
Answer:
(4, 4) is the solution to both lines A and B.
Step-by-step explanation:
The solution to a system of equations is the point at which the two lines intersect. Lines A and B intersect at point (4,4). This means (4,4) is the point which makes both equations true for the same values. The correct answer is "(4, 4) is the solution to both lines A and B."
Hi there!
24. 6x² + 19x + 3
1 3 multiply 6 × 3 = 18
6 1 multiply 1 × 1 = 1
18 + 1 = 19
(x + 3)(6x + 1)
I just simply found the two factors of 6 and 3 that can add up to 19.
This way is useful when the a and c don't have much factors.
27. 5y² + 13y + 6
1 2 5 × 2 = 10
5 3 1 × 3 = 3
10 + 3 = 13
(x + 2)(5x + 3)
30. 16x² + 16x + 3
For this one, 16 has a lot of factors. So you can try "Grouping" method.
You multiply 16 and 3. 16 × 3 =48
Find the factors of 48 that can add up to 16.
Hmm.. 12 and 4 would be great.
Then rewrite the equation.
16x² + 12x + 4x + 3
We would factor 16x² + 12x and 4x + 3 separately.
16x² + 12x 4x + 3 can't be factored more.
4x(4x + 3) 1(4x + 3)
(4x + 1)(4x + 3)
So your answers are....
24. (x + 3)(6x + 1)
27. (x + 2)(5x + 3)
30. (4x + 1)(4x + 3)
Hope this helped!!
Answer:
Density of steel = 80.73 gm/
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:
Density of Wood , 
= 0.68g/
We know that formula of Density is:
Putting the values:
Total weight = 
970 = 220.32 
= 749.68 gm
Volume of pyramid is given as:
Base is a square with side 6 cm
Density of Steel/Pyramid:
