The number of non-blue marbles you need to combine with the blue marbles to achieve a probability of 0.1 is 28.
<h3>How many non-blue marbles are needed?</h3>
Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
Probability of picking a blue marble = number of blue marble / total number of marbles
4 / (4 + 8)
4/12 = 0.33
The number of non-blue marbles needed = ( 4 / 0.1) - 12
40 - 12 = 28

Answer:
6 1/4
Step-by-step explanation:
Total length of the ribbon= 15 3/4 m= 63/4 m
One piece= 9 1/2 m= 19/2 m
Other piece length =X
X= 63/4-19/2
=63/4-38/4
=25/4
=6 1/4

Answer below :)
Step-by-step explanation:
Hi there!
Question 4 - the answer will be 5. Since the scale factor is 5, we would (hypothetically) multiply the area by 5 to get the new area of XYZ, so area XYZ is 5 times the area of ABC.
Question 5 - A.
First we multiply 45 by 12 to find the amount in inches. This is 540. Now, we divide that by 6 to get 90. This is our scale factor in inches, but the answers only show the scale in feet, so we have to convert. Divide 90 by 12 to get 7.5.
I hope this helps!
The answer is 2/3
I hope this works for you :)
