Answer:

3/4

Step-by-step explanation:

Start by simplifying (2x-x) to just (x)

The equation should now look like this: 12+x=9x-6

Now subtract the x on the left side of the equation on both sides.

The equation should now look like this: 12=8x-6

Now add 6 on both sides

The equation should now look like this: 6=8x

To get x by itself you must divide 8 on both sides

The equation should now look like this 6/8=x

Don't forget to simplify your fractions!

6/8 simplified is 3/4, giving you the answer 3/4

Help answer please!!

Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\$

Now we take square root on both sides,

$\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\$

so the value of h equals 19.7 ft.

The mean and standard deviation when presenting results?

krek1111 [17]

Answer:

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
