Answer:  

answer is b. 7/19

Step-by-step explanation:

A: event of drawing first white card

P(A)= 2/5

B/A: event of drawing second white card given first white card has been drawn

we have to find P(B/A)

A∩B: event of drawing two white cards without replacement

P(A∩B)=14/95

baye's theorem says that

P(A∩B)=P(A)×P(B/A)

14/95=P(B/A)×2/5

⇒P(B/A)=7/19

hence,<u> answer is b. 7/19</u>

3. x: 180-99 = 81º (angles on a straight line equals 180)

y: 115-81 = 34º (exterior angle is sum of opposite interior angles)

4. y: 180-64 = 116 (angles on a straight line equals 180)

x: 126º

two steps

angles on straight line equals 180: 180-118 = 62º

exterior angle is sum of opposite interior angles: 62+64 = 126º

sorry if i misread any of the numbers, let me know if i did and i'll fix it

What is the height of the box
PSYCHO15rus [73]

Answer:

8 in

Step-by-step explanation:

since the box is the same length in all sides, it is a cube.

length, width and height are all the same.

the volume is 512 in³.

and the volume of a cube is length×width×height = side length³.

512 = length³

length = 8 = width = height
