We can use the distributive property for this:
-5(3 - 6) = -45
-15 + 30 = -45
15 = -45.
Soooo that's like the farthest you can simplify... and both sides aren't equal...sooo yeah.
Answer:
Option C. No, because the two populations from which the samples are selected do not appear to have equal variances.
Step-by-step explanation:
The variance measures how far a set of (random) numbers are spread out from their average value.
The fact that the younger adults show diversity in their brain activity while the older adults produce similar activities show that there are no equal variances in the two populations from which the samples are selected.
Therefore it would not be valid for Dr. Park to use the independent-measures t-test to test whether the brain activity of younger adults is different from that of older adults during a visual recognition task
Answer:B
Step-by-step explanation:
Answer: 6
Step-by-step explanation:
Let's start by getting the equation to slope intercept form
First simplify

Then get y by itself

In slope intercept form y=mx+b, m is the slope
In this case the slope is 6
I think it’s the first answer! Good luck!
