Answer:
QS = 42 units
Step-by-step explanation:
8x - 51 = 3x - 6
5x = 45
x = 9
(8x - 51) + (3x - 6) = QS
72 - 51 + 27 - 6 = QS
42 = QS
The domain is all the values of x which are covered by the function. In this case, the domain is x <= 0. The range is all the values of y that the function passes through, so in this case, the domain is y >= 0. The only correct statement among the choices is the second.
Answer:
approximately 13.9 inches
Step-by-step explanation:
That's 8√6, not 8V7.
The four sides are of the same length (x). According to the Pythagorean Theorem, x² + x² = (diagonal length)² = (8√6)², or
2x² = 64(6) = 384
Dividing both sides by 2, we get:
x² = 192, or x² = 4(48). Then the side length is x = √16√12, or
x = 4√4√3 = 8√3. This is approximately 13.9 inches.

By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).
