Answer: D. Replicate the experiment to see whose results are more reliable.
Step-by-step explanation:
The experiments are similar, then we should expect to see similar results.
Now, we know that they get different results, let's analyze the options:
A) With the given information we can not conclude which is the incorrect experiment, then this is discarded.
B) We can not really determine that both students are in correct only knowing the experiment and the results, so this is also discarded.
C) You can not assume things.
D) This is the correct option, an experiment must be repeatable. This means that, with the same conditions, the result must be always the same.
Then we can replicate both experiments and see if the results are the same as before to determine if the results are reliable.
Part A:
The scale factor is 1/4, because you obtain the coordinates of points P', Q', R' by dividing the coordinates of P, Q and R respectively by 4.
Part B:
Reflecting about the y axis causes a sign swap in the x coordinate. So, the new point will be
Part C:
The triangles are similar, but not congruent. When you transform PQR into P'Q'R', you get a scaled version of the original triangle. This means that the angles and the proportion between sizes will be the same, but the length are scaled by 1/4, and the area is consequentially scaled by 1/16.
Triangles P'Q'R' and P''Q''R'' are congruent, so they are both similar but not congruent to the original triangle.
Answer:
0
Step-by-step explanation:
It is 0 because the slope intercept form is y=mx+b right now you only have the y intercept which is the b of the equation. That means that your slope is non existence
Answer:
2
Step-by-step explanation:
Answer:
The package weighs 21.6 pounds
Step-by-step explanation:
$4 dollars + T(0.60 tax per pound) divided by 15.40( the full cost of the shipment)
15.40 divided by 0.60 = 25.6
25.6 - 4 = 21.6
