Answer:

5/(5+5+10)*(4/(4+5+10)

Step-by-step explanation:

there are 20 marbles, 5 red ones. there is 5/20 chance or 1/4 chance you draw a red one. Then if you do draw a red one, there are 4 red ones left in 19 marbles, so you multiply (1/4)*(4/19)

Which equation has the steepest parabola?
ICE Princess25 [194]

Given:

The equations of parabolas in the options.

To find:

The steepest parabola.

Solution:

We know that, if a parabola is defined as

(y-k)=n(x-h)^2

Then, the greater absolute value of n, the steeper the parabola.

It can be written as

\dfrac{1}{n}(y-k)=(x-h)^2

p(y-k)=(x-h)^2

where p=\dfrac{1}{n}, the smaller absolute value of p, the steeper the parabola.

Now, find the value of |p| for eac equation

For option A, |-0.5|=0.5

For option B, |5|=5

For option C, |8|=8

For option D, |-10|=10

Since, the equation is option A has smallest value of |p|, therefore, the equation (x+2)^2=-0.5(y+3) represents the steepest parabola.

Hence, the correct option is A.

Solve each linear system by Elimination. 2x + 3y =2, 4x-2y=4
KonstantinChe [14]

Answer:

Step-by-step explanation:

First, we will eliminate the x, so we multiply the first one by 2.

4x+6y=4

4x-2y=4

So, we have y=0, and we put that in the equations, so x is 1
