Multiplying by 2, the next one would be 160
To solve for x, first, we add 3 to the given equation:
Dividing by 2, we get:
Therefore:
Finally, subtracting 5 we get:
Answer:
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> .
Acute would be less than 90 degrees, obtuse is greater than 90 degrees and right is 90 degrees
W = 2. How do we find this out?
Put "w" as "2". 8-2(2)=6(2)-8
8 - 4 = 12 - 8.
Solve.
4 = 4
Hope this helps! ☺♥
