Measurement is ___________ when it yields the same values across repeated measurement of the same event.

Mathematics
1 answer:
Romashka [77]4 years ago

<span>The answer is reliable. A measure is assumed to have a high reliability if it yields parallel results under steady conditions. It is the characteristic of a set of test scores that relates to the quantity of accidental or random error from the measurement procedure that might be rooted in the scores. Marks that are highly reliable are precise, reproducible, and constant from one testing time to another. To be exact, if the testing method were to be repeated with a different group of test takers, fundamentally the same results would be gotten. </span>

A mountain climber ascends a mountain to its peak. The peak is 14,090 ft above sea level. The climber then descends 490 ft to me
lana66690 [7]
The value of asked for is obtained by subtracting the distance traveled downward by the climber from the peak elevation. This is shown below,
                                    d = 14,090 ft - 490 ft
The value is equal to 13600 ft. Thus, the climber is 13,600 ft from the ground.

If a correlation coefficient was r = -0.94, what would this represent?
nasty-shy [4]

Answer:

this would represent a strong negative

Step-by-step explanation:

on a correlation line you have strong negatives,weak negatives,none,weak positives, and strong positives.Since the coefficient is a hand negative, focus on the left side. A weak negative is -0.5 greater than or equal to so since -0.94 is less than -0.5 it advances on to the next category of the correlation line, thus resulting in the correlation coefficient to be a strong negative.

PLEASE HELP QUICKKK ITS DUE AT 12!!! An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases
lys-0071 [83]

Answer:

Trust me, I know my stuff.

Step-by-step explanation:

Use the diagonals to make two triangles. They will be the longest sides. We know two sides and an angle are congruent. By use of the Side Angle Side congruence conjecture, we know the triangles are congruent. Corresponding parts of congruent triangles are congruent, therefore, the diagonals must be congruent. Good luck.

swat32

Answer:

\left(x^{2-8}\right)+\left(-2x^2\right)=\frac{1}{x^6}-2x^2

Step-by-step explanation:

\left(x^{2-8}\right)+\left(-2x^2\right)

=x^{2-8}-2x^2

=x^{-6}-2x^2

=\frac{1}{x^6}-2x^2
