D. a set of cards has 25 cards with stars, 15 cards with squares, and 10 cards with circles. find the probability of each event

Dvinal [7]

Answer:

look below

Step-by-step explanation:

The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:

P of picking card with star:

25/50=0.5

Card with square:

15/50=3/10=0.3

Card with circle: 10/50=1/5=0.2

We can then put these values into parts a,b,c, and d:

a) 3/10 chance or 30%

b) 1/5 chance or 20%

c) 1/2+1/5=7/10 chance or 70%

d) 1-0.3-0.2=1/2 chance or 50%

The graph of function g(x) is a transformation of the graph of function f(x) = x2.g(x) =

mariarad [96]

Given:

The graph of function g(x) is a transformation of the graph of function f(x) = x²

As shown: the graph of g(x) is open down

So, we will reflect f(x) over the x-axis, the function will be ⇒ -x²

And there is horizontal compression so, the factor of compression will be > 1

So, the function will be ⇒ -2x²

Finally, there is a vertical shift down 3 units

So,

$g(x)=-2x^2-3$

Please help asap<br><br> solve x^4+5x^2+4=0

const2013 [10]

Answer:

$x=\pm i\text{ or }x=\pm2i$

Step-by-step explanation:

So we have the equation:

$x^4+5x^2+4=0$

Let's let u be equal to x². So:

$u^2+5u+4=0$

Factor:

$(u+1)(u+4)=0$

Zero Product Property:

$u+1=0\text{ or } u+4=0$

Subtract:

$u=-1\text{ or }u=-4$

Replace:

$x^2=-1\text{ or }x^2=-4$

Take square root:

$x=\pm\sqrt{-1}\text{ or }x=\pm\sqrt{-4$

Simplify:

$x=\pm i\text{ or }x=\pm2i$
