The simplified fraction is 3 1/10 The exact answer is 3 10354/100000
Ok so first you need to identify what you are looking for... you need to find x.
to do that you need toge it on one side. so cancel out the "-2x" on the left side by adding 2x(on both sides, don't forget you add common variables). now you should have something like this...
-15=8x+9
now all you have to do is get rid of the 9 by subtracting 9 on both sides
you should have
-24=8x
With that, all you have to do now is divide 8 into both sides and it should look like a fraction now
-24/8=8x/8
the 8x/8 will cancel out the 8 and you will have
-24/8=x
Simplify that and you should get
-3=x
need me to explain it with fewer words?
Answer:
Step-by-step explanation:
36/25 = 1.44
√1.44 = 1.2
H = 45×1.2 = 54 cm
L = 80×1.2 = 96 cm
W = 25×1.2 = 30 cm
9514 1404 393

Step-by-step explanation:
Read the values from the graph in the usual way: find the x-coordinate, then locate the point on the graph and find its y-coordinate.
You find the y-coordinate by following the horizontal line to the y-axis, where the numbers are.
Answer:
And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution 
and for this case we know that the distribution is given by:
And the standard error would be:
And replacing we got:
