The probability of drawing the initial Jack is 4 out of 52 as there are 4 Jacks in deck of 52 cards. Since you are not replacing the Jack the Deck now has 51 cards and 3 Jacks making that 3 out of 51

A circle is centered at the point (-3,2) and passes through the point (1,5). What is the radius of the circle?
Akimi4 [234]

Answer:

5

Step-by-step explanation:

The radius is a distance on a circle from the center to a point on the circle.

We have both of these points describe here in this definition.  Using the distance formula will give us the radius.

\sqrt{(x \text{ difference })^2+(y \text{ difference})^2

The difference between 1 and -3 is 1-(-3)=4.

The difference between 5 and 2 is 5-2=3.

\sqrt{4^2+3^2}

\sqrt{16+9}

\sqrt{25}

Let X = the number of nonzero digits in a randomly selected 4-digit PIN that has no restriction on the digits. What are the poss
NISA [10]

Answer:

X = {0, 1, 2, 3, 4}

Step-by-step explanation:

If X is the number of nonzero digits in a 4-digit PIN with no restriction on the digits, the pin can have up to 4 nonzero digits.

Let's see some examples:

If the PIN is 0000 then X = 4

If the PIN is 2045 then X = 3

If the PIN is 7546 then X = 0

From the previous examples, we can see that the possible values for X are 0, 1, 2, 3, 4.

Thus X = {0, 1, 2, 3, 4}

FromTheMoon [43]

Answer:

y=[-2]x[+][5]

Step-by-step explanation:

\frac{-1-3}{3-1}=\frac{-4}{2} =-2 m= -2

Using the point (1,3) Find the value of b

3= -2(1)+b

3= -2+b

+2  +2

---------

5=b
