4 0

Answer:

4/16 or .25

Step-by-step explanation:

Probability of the first being prime is 2 of 4 becasue two cards are prime

You put the card back, so the probability of the second card also being prime is also 2/4

Multiply the numerators together and then the denominators together

2*2 = 4

4*4 = 16

so the probability of picking a prime number and then picking a prime number with replacement is 4/16 or .25.

Hope this helps!

Answer:

Answer is $\frac{4}{3}$

Step-by-step explanation:

To find the interval of x. Use our equations to equal each other.

$-x^2+2x=y,y=0$

$-x^2+2x=0\\-x(x-2)=0\\-x=0 , (x-2)=0\\x=0 ,2$

$\int\limits^2_0 {-x^2+2x} \, dx$

Integrate.

$\frac{-x^3}{3}+x^2\\(\frac{-2^3}{3}+2^2)-[\frac{-0^3}{3}+0^2]\\-\frac{8}{3} +4-0\\-\frac{8}{3}+\frac{12}{3} =4/3$

Using Desmos I have Graphs of both of the equations you have provided. The problem asks us to find the shaded region between those curves/equations.

Proof Check your interval of x.
