Will name brainliest! which events are independent? select each correct answer. a. a six-sided number cube is rolled and a coin is flipped. b. two spinners are spun at the same time. c. two white balls are drawn from a bag of balls without replacing the balls d. one coin is drawn from a bag of coins after another coin is drawn without replacement. ! it would mean so ! : )

You can't really answer C and D see below. You might be intended to A and B are the only independent events.

A and B are independent.

Step-by-step explanation:

A is. The cube could show a 5. Would that influence what the coin does or is going to do. A is independent.

B is. The spinners are not going to influence each other. B is independent

C can't tell. What is the nature of the color of the balls. If they are all white, then it doesn't matter. If there is a choice in colors the second will be influenced by what happens to the first.

D same answer as C. If the coins are the same, the first does not influence the second.  If the coins are different, the first will influence the second.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
