Answer:

14

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (5+9+10)/3 = 24/3 = 8

∑ ( y − ȳ ) ² =  ( 5 − 8 ) ² +  ( 9 − 8 ) ² +  ( 10 − 8 ) ²

=  (  − 3 ) ² +  (  1 ) ² +  ( 2 ) ²

= 9 + 1 + 4

= 14

How many people own a SUV?<br> A. 4<br> B. 42<br> C. 420<br> D. 4,200
MaRussiya [10]
For this, no math is even needed! The question says 1,000 people were interviewed. 42% percent of that 1,000 owns an SUV. If it's a percent, it is 42/100, right? Now we have to make that 42/100 out of 1000. We add a zero to the 100 on the bottom (42/1000). We do the same thing on the top. Add a zero! 420. 

SECOND POSSIBLE SOLUTION
Solve this with logic! 42% is nearly 50%. Half of 1,000 is 500. What is closest to 500? 420! This solution is even easier.

Hope this helps you!
