Question

Tell if the events are independent or dependent. Explain your reasoning.



A spinner lands on 10. The same spinner is spun again and lands on 10 again.



A.
The events are independent, because the events affect each other.


B.
The events are dependent, because the events affect each other.


C.
The events are independent, because the events do not affect each other.


D.
The events are dependent, because the events do not affect each other.

Answer 1

C. If you spin a spinner once, does a number disappear the next time you spin it? No, right?

Answer 2

Tell if the events are independent or dependent. Explain your reasoning.

Mr. O’Leary gets heads on a coin toss and then gets tails by tossing the same coin again.



A.
The events are dependent, because the events affect each other.


B.
The events are dependent, because the events do not affect each other.


C.
The events are independent, because the events affect each other.


D.
The events are independent, because the events do not affect each other.

Answer 3

Here is how I remembered Independent and dependent variables.

Dry Mix.
Dependent variable (D) goes on the 'y' axis. The y axis is the vertical length of a graph. It shows the thing you measure on your graph.

Independent variables (I) goes on the 'x' axis, the x axis is horizontal, and the thing you change on purpose.

Makes sense so far?

Answer 4

kinda but what is the answer? ive been stuck on this test for HOURS!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 5

Hehe, ok, so for number 1 the same spinner is spun, so we are testing the same independent variable on the 'x' axis.

If you spin 10 twice, that means it is affecting the outcome in some way.

So my guess is that it is C

Answer 6

this is maddening!!

Answer 7

number 2?

Answer 8

what about the question 2?

Answer 9

A.

B.

C.
The events are independent, because the events affect each other.


D.
The events are independent, because the events do not affect each other.

Answer 10

For number 2, I am also going to guess D,

If you are using an independent variable for 2 outcomes, it is a 50/50 chance right? So no matter what coin you are using, it is not affecting the outcome.

This is only from what I learned, not quite sure because those questions are pretty lame.

Answer 11

Good luck

Answer 12

done leave

Answer 13

A number cube with faces numbered 1 through 6 is rolled and a coin is tossed.

What is the probability that the number cube will show a number greater than 4 and the coin will land with tails up?



A. 1/12




B. 1/6




C. 2/5





D.5/6


I think its D
