You have 4 in 52 (4/52) chance that the first card is a jack and a 3 in 51 (3/51) chance the second card is a jack

Multiply the two
4/52 x 3/51
1/13 x 1/17
1/221

Answer:

D= 10

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(0-6)^2+(1-9)^2}\\d=\sqrt{(-6)^2+(-8)^2}\\d=\sqrt{(36)+(64)}\\d=\sqrt{100}\\d=10

Airida [17]

Answer:

About 316.13

Step-by-step explanation:

We know:

Diameter (d) = <u>11</u> (of the circle)

Area of the circle: pi(11)^2 = <u>121pi </u>

Side of the square = <u>8 </u>

so area of the square is 8^2 = <u>64</u>

Area of the shaded region:

121pi-64 =316.13

hope this helped

Which equation represents y = x2 − 10x + 30 in vertex form?
riadik2000 [5.3K]

To complete the square, you can add (and subtract) the square of half the x coefficient.

... y = x² -10x + 30

... y = (x² -10x +25) + (30 -25)

... y = (x -5)² +5

The equation is not setup properly, possibly it is your teacher's fault.

From external research, I would say the answer is x = -12.
