b = -0.5
4 + 2 = - 0.5 * 4 + 8
6 = -2 + 8
6 = 6
Which is true, Therefore the answer is -0.5
Using long division, we get
2x-5
x+3 | 2x^2+x-15
- (2x^2+6x)
_________
-5x-15
-(-5x-15)
________
0
2x-5 is your answer
Answer:
a. Experiment
b. yes
Step-by-step explanation:
The study being conducted in this scenario is an experiment because different groups are being created and both an independant variable and dependant variable are being introduced. This means that there is researcher involvement and therefore makes this an experiment and not an observational study.
Yes, a case can be made for such a claim. This is because the music being played is the dependent variable in each of the groups. Meaning that the only difference in each of the groups was the music. Therefore, any differences in the data gathered can be connected to the music.
Answer:
Step-by-step explanation:
The formulas for the areas of a rectangle and a parallelogram are actually the same; both involve length and width.
It may be easier to understand this if you draw a rectangle of width w with a drawing of a parallelogram of width underneath. The parallelogram's ends appear slanted; they are neither vertical nor horizontal. However, so long as you measure the length of the rectangle horizontally, all measurements are equal to each other as well as equal to the length of the rectangle.
Hence the calculated areas will be one and the same.
