Find the variance of the given data rounded to the nearest hundredth.

3,4,5,7,10,12,15

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Where’s the graph too show me?
