Suppose you are trying the test hypothesis

1 answer:

7 0

You could give an example or research into previous hypothesis and tests for the topic you are on.
You could also link your hypothesis to something opposite. (Eg: If you were looking at ice melting you may want to also look at how it freezes, this would show that even though something happens it reverses to its original state, in this case water.)

What are two step equations

miskamm [114]

2 step equations are equations that require 2 steps to solve it.

For example, 2x + 5 = 3x + 6

To solve for x, we must isolate it.

First subtract 2x on both sides, which is ONE step.

2x + 5 = 3x + 6
-2x -2x

5 = x + 6

The we must subtract 6 from both sides of the equation, which makes is the second step.

5 = x + 6
-6 -6

-1 = x

-1 would be the answer and we only used 2 steps to solve it.

There are 20 students in a math class. Thirty percent of the

Mekhanik [1.2K]

Answer:

Step-by-step explanation:

20% of 30 is 6 are randomly selected.

30 choose 6 = 30! / (30-6)! 6!

= 30! / 24!6!

= 30 * 29 * 28 * 27 * 26 * 25

--------------------------------- <-- 24! cancels

6 * 5 * 4 * 3 * 2 * 1

= 29 * 28 * 27 * 26 * 25

---------------------------------- <--- 30 = 6 * 5 cancels

4 * 3 * 2 * 1

= 29 * 7 * 9 * 13 * 25 <-- 4 cancels 28, 3 cancels 27, 2 cancels 26

= 593775

Find the y and x-intercept for <br> -x+3y+3

Darya [45]

-x+3y+3=0 <-- This puts the expression into an equation to make it solvable.
3y+3=x <-- Use Addition Property of Exponents to move the (x) to the right
3y=x-3 <-- Use Subtraction Property of Exponents to move the (3) to the right
y= $\frac{1}{3}$ -1 <-- Use Division Property of Exponents to remove the 3 from y
y= $\frac{1}{3}$ -1 < This is the equation for the y-intercept

-x+3y+3=0 <-- Same as above, makes it so the expression is an equation to solve
-x+3=-3y <-- Use Subtraction Property of Exponents to move the 3y to the right
-x=-3y-3 <-- Use Subtraction Property of Exponents to move the 3 to the right
x=3y+3 <--Use Divison Property of Exponents to remove the -1 from x
x=3y+3 <-- This is the equation for the x-intercept

Hope this helped!
