Camila sets up a passcode on her tablet, which allows only nine-digit codes. A spy sneaks a look at Camila's tablet and sees her
laila [671]

Answer:

\frac{1}{10^9} probability the spy is able to unlock the tablet on his first try.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

1 correct password, so D = 1

Total outcomes:

Nine-digit codes.

For each digit, there are 10 possible outcomes. So

T = 10^9

What is the probability the spy is able to unlock the tablet on his first try?

p = \frac{D}{T} = \frac{1}{10^9}

\frac{1}{10^9} probability the spy is able to unlock the tablet on his first try.

(X+2)^2+(y-4)^2=16 what is the radius
Sholpan [36]

Answer:

The radius = 4

Step-by-step explanation:

considering the equation

\left(x+2\right)^2+\left(y-4\right)^2=16

As the standard form of the circle is

\left(x-h\right)^2+\left(y-k\right)^2=r^2

Match the values in this circle to those of the standard form.

  • The variable  r represents the radius of the circle,  
  • h represents the x-offset from the origin, and  
  • k  represents the y-offset from origin.

\mathrm{Rewrite}\:\left(x+2\right)^2+\left(y-4\right)^2=16\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}

\left(x-\left(-2\right)\right)^2+\left(y-4\right)^2=4^2

\mathrm{Therefore\:the\:circle\:properties\:are:}

\left(h,\:k\right)=\left(-2,\:4\right),\:r=4

Therefore, the radius = 4
