Answer:
27x-68
Step-by-step explanation:
-4(2x+3)+7(5x-8)
= -8x-12+35x-56
=27x-68
Answer:
The answer is: When the sample mean is not a whole number.
Explanation:
The "Sum of Squares" <em>(SS)</em> refers to the measure of the distance from the mean. This can be computed by subtracting each of the measurements from the mean. The difference will then be squared and the measurement results will be added together. This formula is known as "definitional formula." This is preferably used when the mean is a whole number and there are only a few number of scores.
On the contrary, the "computational formula" allows the calculation of the concept values. This is preferably used when the mean is not a whole number and when there are many scores.
Answer:
<u>If mixed numbers are </u>
<u>You can write them as a sum of a whole and fraction and use the distributive property of multiplication:</u>
- a b/c × d e/f =
- (a + b/c) × (d + e/f) =
- ad + a(e/f) + d(b/c) + (b/c)(e/f)

Answer:
You know that the Pythagorean Theorem can be used to solve for unknown lengths in a right triangle. ... The Pythagorean. Theorem states that, if a triangle is a right triangle, then the square ... Given a Pythagorean triple, you can identify other right triangles by multiplying each side length by the same factor
