Answer:
1/5
Step-by-step explanation:
This are the possible outcome
RRR BBB YYY
RBY RYB RYY RBB
BRY BYR BRR BYY
YRB YBR YRR YBB. Total 15
R red
B blue
Y yellow
Probability = numbers of required outcome/number of possible outcome
No of possible outcome =15
No of required outcome = 3 red marbles
So
3/15
P(3red marbles) =1/5
Answer:
Mean: 6
Median: 6
Range: 8
Step-by-step explanation:
Mean is found by adding up all the values in the set and dividing by the amount of numbers in the set (in this one there are 8) 2+3+4+5+7+8+9+10=48. 48 divided by 8 = 6.
Median is the number in the middle, when the numbers in the set are ordered from least to greatest. Since there are two middle numbers in this set we add them together and divide by 2. 5+7=12. 12 divided by 2 = 6.
Range is found by taking the largest number and subtracting the smallest number from it. 10-2=8.
I can help with the second part of your question. The first part is missing something.
To find the amount of interest, just multiply the amount by the given percent.
200 x 0.03 = 6
150 x 0.03 = 4.5
6 - 4.5 = 1.5 is the additional amount of interest.
I believe its 5 bags, 1 granola bar in each bag and 2 pieces of fruit in each bag.
This is a fairly easy half-life problem
Each half-life reduces the radioactive material by one half.
So after 72 hours the radioactive material would have undergone 6 half-lives.
2^6 = 64.
So, there will be one sixty-fourth of the material left.
520 / 64 = 8.125 grams will remain.
radioactive decay is an exponential decay function.
