We have 2( x^2 + 5x + 6) ÷ (x + 3) = 2(x^2 + 3x + 2x + 6) ÷ (x + 3) = 2[ x( x + 3) + 2( x + 3)] = 2( x+ 3 )( x + 2 ) ÷ ( x + 3 ) = 2( x + 2 ) = 2x + 4.
Theoretically 10 because the 50/50 chance realistically though you'll get more or less
You divide 2 by 9 which is .2222--- or .2 if you round it to the nearest tenths.
Whenever you want to change a fraction to a decimal, you divide the numerator by the denominator.
Answer:
The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
So it is z with a pvalue of 
, so z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
Ok if a student walks 17 meters in 30 seconds he walks 34 meters in a minute 17+17=34 then you take 34(meters in a minute) multiply by 60(minutes in an hour) you get 2040 34x60=2040meters 1609.34 meters equal a mile 2040-1609.34=430.66 meters left theres 1.09361yards in a meter so 430.66x1.09361=470.97yards
so i guess you could say a student would walk 1mile and 470.97 yards if he walked 17 meters in 30 seconds for an hour straight
p.s it made sense in my head
