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> .
Answer:
If the quetion is how much money I earned on both days it would be 56.25
Step-by-step explanation:
4hours times 6.25 an hour = 25 now we do 5hours times 6.25 an hour = 31.25 so add them to get 56.25
Answer:
75 degrees
Step-by-step explanation:
let x unknown number
5x+10x+9x=180
24x=180
x=7.5
largest angle
10x
10×7.5=75
Your least common denominator is 36.
So 3/18x⁵ becomes 6/36x⁵
5/36x² stays
8/9x³ becomes 32/36x³
Answer:
6x - 18
Step-by-step explanation:
2x−6+4x−12
