Q and R are independent events. P(Q) = 0.4; P(Q AND R) = 0.08. Find P(R).

algol [13]

Because Q and R are independent, you have

$\mathbb P(Q\cap R)=\mathbb P(Q)\times\mathbb P(R)$
$0.08=0.4\times\mathbb P(R)$
$\implies \mathbb P(R)=0.2$

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Brrunno [24]

Answer:

Converges at -1

Step-by-step explanation:

The integral converges if the limit exists, if the limit does not exist or if the limit is infinity it diverges.

We will make use of integral by parts to determine:

let:

$u=x$ $dv=e^(2x)\cdot{dx}$

$du=dx$ $v=2\cdot{e^(2x)}$

$\int\limits^a_b {u} \, dv = uv -\int\limits^a_b {v} \, du$

$\int\limits^a_b {x\cdot{e^2^x} \, dx =2xe^2^x- \int\limits^a_b {2e^2^x} \, dx$

$\int\limits^a_b {xe^2^x} \, dx = 2xe^2^x-2e^2^x-C$

We can therefore determine that if x tends to 0 the limit is -1

$\lim_{x \to \0} 2xe^2^x-2e^2^x=0-1=-1$

Solve the equation... 10x - 12 = 48 - 2x

hjlf

If you would like to solve the equation 10 * x - 12 = 48 - 2 * x, you can calculate this using the following steps:

10 * x - 12 = 48 - 2 * x
10 * x + 2 * x = 48 + 12
12 * x = 60 /12
x = 60 / 12
x = 5

The correct result is 5.

HELP! LOTS OF POINTS

seropon [69]

Use the equation=
x^2+5^2=9^2
x^2+25=81
x^2+25-25=81-25
x^2=56
$\sqrt{x} = \sqrt{56}$
x=7.48331477355
