Answer: The correct answer is D. Ask a question that can be answered by making observations.
Explanation:
Basically, in order to develop a testable hypothesis, scientists must adhere to the guidelines of the scientific method.
The scientific method is usually understood to be a so-called hypothetical-deductive method, the core of which is to make hypotheses based on observations or measurements, to make predictions based on them and to check the validity of predictions by repeated experiments. More generally, the scientific method is a general way of obtaining solid knowledge, using many means of proof, both empirical and theoretical, to achieve certainty. The scientific method is a widely recognized tool in the scientific community for seeking objectivity, reliability and transparency in research.
which of the following describes a major sector of a circle
The major sector of a circle is described as: a region bounded by two (2) radii and an arc which measures 200 degrees.
The sector of a circle can be defined as a pie-shaped portion of a circle is enclosed or bounded by two (2) radii and an arc of the circle.
In Mathematics, the sector of a circle is divided into two main categories and these include:
Minor sector: it is the smaller area and it forms a central angle that is less than 180 degrees.Major sector: it is the larger area and it forms a central angle that is greater than 180 degrees.In conclusion, the major sector of a circle is described as a region that is bounded by two (2) radii and an arc which measures 200 degrees or greater than 180 degrees.

The transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.
The table is given as:
Original point ---- Image
A (-4,-1) (1,-4)
B (-7,-6) (6,-7)
C (-14, -6) (6,-14)
D (-11, -1) (1,-11)
From the table, we can see that;
The coordinates are swapped, and the new x-coordinate is negated.
This represents 90 degrees counterclockwise rotation across the origin.
The rule of this transformation is:
[tex](x,y) \to (-y,x)[/tex]
i.e.
[tex](-4,-1) \to (1,-4)[/tex]

triangle FGH is inscribed in the circle above. If FG is congruent to GH and the measure of G is 30 what is the measure of H
Applying the inscribed angle theorem, the measure of ∠H is: C. 75°
Recall:
Based on the inscribed angles theorem, the measure of an inscribed angle = half of the measure of the intercepted arc.Since arc GH is congruent to arc FG, therefore:
m∠F = m∠H
Thus:
m∠H = 1/2(180 - m∠G)
Substitutem∠H = 1/2(180 - 30)
m∠H = 1/2(150)
m∠H = 75°
Therefore, applying the inscribed angle theorem, the measure of ∠H is: C. 75°

A survey participant is randomly selected. Let f be the event that the participant’s first motor vehicle had four cylinders and let u be the event that the participant’s first motor vehicle was an suv. What is the value of p(fc and u)?.
The value of P(fc and u) is 0.09
From the complete question, we have the following highlights:
A total of 200 participants were surveyed.18 of the survey participant's first motor vehicle had four cylinders and the participant’s first motor vehicle was an SUV.These mean that;
[tex]n(fc\ and\ u) = 18[/tex]
[tex]n =200[/tex]
So, the value of P(fc and u) is calculated using:
[tex]P(fc\ and\ u) =\frac{n(fc\ and\ u)}{n}[/tex]
This gives
[tex]P(fc\ and\ u) =\frac{18}{200}[/tex]
Divide 118 by 200
[tex]P(fc\ and\ u) =0.09[/tex]
Hence, the value of P(fc and u) is 0.09

A varies jointly as of the product of b and c. If a = 24 when b = 8 and c = 2, find b when a = 48 and c = 4.
Variation can be direct, inverse or joint.
The value of B when a = 48 and c = 4 is 8
The joint variation is represented as:
[tex]A \ \alpha\ BC[/tex]
Express the variation as equation
[tex]A = kBC[/tex]
Make k the subject of the formula
[tex]k= \frac{A}{BC}[/tex]
If a = 24 when b = 8 and c = 2, we have:
[tex]k = \frac{24}{8 \times 2}[/tex]
[tex]k = \frac{24}{16}[/tex]
[tex]k = 1.5[/tex]
So, [tex]A = kBC[/tex] becomes
[tex]A = 1.5BC[/tex]
Make B the subject
[tex]B = \frac{A}{1.5C}[/tex]
When a = 48 and c = 4, we have:
[tex]B = \frac{48}{1.5 \times 4}[/tex]
[tex]B = \frac{48}{6}[/tex]
Divide
[tex]B = 8[/tex]
Hence, the value of B is 8

What is the domain of the function y=2 square root x-5.
Answer:
x ≥ 5
Explanation:
so, we have
y = 2√x-5
We know that the radicand (number under a radical) must be greater than or equal to zero so, we set up the equation as
x - 5 ≥ 0
to solve it, we add 5 to both sides and you get
x ≥ 5
the domain is the interval---> [5,∞)

If differential heating did not occur on earth, which scenario would become true?.
There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.
When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.

Graph the image of this figure after a dilation with a scale factor of 3 centered at (−7, −6). Use the polygon tool to graph the dilated figure.
The dilation transformation gives an image that is similar to the pre-image
but have a different size.
Please find attached the required graph of the image created with MS ExcelReasons:
Points on the figure are; A(-7, -3), B(-3, -2), C(-4, -5)
The scale factor of dilation = 3
The center of dilation = (-7, -6)
Required:
The graph of the image following the dilation.
Solution:
The given points relative to the center of dilation are;
(-7 - (-7), -3 - (-6)) = (0, 3)
(-3 - (-7), -2 - (-6)) = (4, 4)
(-4 - (-7), -5 - (-6)) = (3, 1)
Following the dilation gives;
3 × (0, 3) = (0, 9)
3 × (4, 4) = (12, 12)
3 × (3, 1) = (9, 3)
Adding the coordinates of the center of dilation to the above relative points of the image gives;
Location of point A' = (0 + (-7) , 9 + (-6)) = (-7, 3)
Location of point B' = (12 + (-7) , 12 + (-6)) = (5, 6)
Location of point C' = (9 + (-7) , 3 + (-6)) = (2, -3)
Therefore, the image is; A'(-7, 3), B'(5, 6), C'(2, -3)
