The question is:15b+m-4b
we have same variables that are 15b and -4b so we can calculate it.Okay first let's calculate the like terms 15b-4b i.e 11b and the +m remains the same so the answer is:11b+m
If angles are the same, then their opposite edges also the same. So 2x-6 = x
If you solve it you will find x=6
Answer:-1
Step-by-step explanation:
You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .
