I have many groups of replicates and i want to do an LSD test to see which ones are equal and which ones are different. I have no idea how, i can't find the place where it gives you the choice of a Fisher LSD and a Tukey HSD. I know it's there, i just can't find it, and the help file tells me what those test mean but noi clueas to how to do them on the program. please help!!!

1) -i squareroot of 5 * i squareroot of 2

Solve for x:
x-2/ x^2 + 5 x +6 = 3/ x+3 - 2/x+ 2

solve for y:

y/ y-5 = 2/y-3 + 4/y^2-8y +15

for these use f(x)= 2x^3 -x^2 -3x + 2 ; g(x)4x^4-2x^3+ x^2 -6 ; h(x) =-4

1) g(x) * h (x)=

2) f(x) + g(x)-h(x)=

3)divide f(x) by h(x)=

4)f(x) - g(x)=

Next- State the domian and range of the equation y =5+ sqrt. of x+6

Name the test that is used to determine if a graph is a function .

what are the 3 rules for finding horizontal asymtotes.

Solve for x (check for extraneous roots)
7-sqt of x-6=3

sqrrt of 5(x+3)= 10

5 sqrt. of x-3=10

state the domain of the relation { (-4,5), (-3,-4), (-2,0), (1,1) }

the equation x^2 + 4x +y + 4 =0 is an example of which type of conic section?

find the center and the radius of a circle with the equation
(x+5) + (y-2)^2 = 9

what is the equation of a circle with center (2,-4) and radius 4?

what is the equation of a parabola with a focus at (3, -3) and directrix y=3

Somehow, my parent's dauchunds got rat poisoned. It's possible someone wanted to poison some moles and a mole came in the yard and they ate it (they are in a fence). But the dogs have never eaten anything they've killed before. Poor dogs were puking and had diahreah and today one of them was stiff and cold and unconscious. That one is in the dog hospital now and has warmed up a little. I'm suspicious of my muslim neighbors, they have no dogs. the other neighbor has some dauchunds themselves but they're not poisoned. That neighbor said they saw some boys walking around too. I'm just so mad cause they were such sweet lil pups. I know I'll probably never find out who did it, or what really happened, but I just want to try to do something. Poor Freida was nudging her sister with her nose.

We all know that Butterflies come from Catapillars and the way things go on in this ol crazy world was wondering if you have seen also like me a Butterpillar.
It seemed to be half Caterpillar and half Butterfly. Basically a flying Caterpillar. Unfortuantly my Jack Russel saw it on the floor and rushed over and eat it. He loves eating things like that... So have any of you seen this weird insect ???????

Because the force of gravity performs work (as in hydroelectric power) does the force require some kind of energy source in order to maintain its existence. If there is not an energy source, doesn't this mean it is a perpetual motion force?

I have to build a launcher/catapult/slingshot contraption for physics, and what I've done so far hasn't been working. I can only use 10 rubber bands, 5 paperclips, 10 popsicle sticks, and 2 paper towel tubes. The launcher must be freestanding. I can only use tape and glue to hold it together, and it has to launch a ping pong ball 4.5 meters. I'm pretty sure the best way is to build some type of slingshot, but I can't get the paper towel tubes to stay up, even with tape/glue. Also, I can't figure out any ideas on how to make place for the ping-pong ball to sit if I were to do a slingshot. Does anyone have any ideas on how to make this work?
