False, the range is just determined by minising the lowest from the highest, but the variables can still get you the same mean, which can lead to the same standard deviation
I hope this helps you
4plumbers +5helpers =182
5plumbers +6helpers =224
-24plumbers -30helpers =1092
25plumbers+30helpers =1120
1plumbers =28
4.28+5helpers =182
5helpers =70
1helpers=14
I know of two ways to solve quadratic equations. The first is through factoring. Let us take the example (x^2)+2x+1=0. We can factor this equation out and the factors would be (x+1)(x+1)=0. To solve for the roots, we equate each factor to 0, that is
x+1=0; x+1=0
In this case, the factors are the same so the root of the equation is
x=1.
The other way is to use the quadratic formula. The quadratic formula is given as [-b(+-)sqrt(b^2-4ac)]/2a where, using our sample equation above, a=1, b=2 and c=1. Substitute these to the formula, and you will get the same answer as the method above.
Above is postive. So the answer is +300
i dunooo i dont even nooooo
