Answer:
P=3/(3+4+7)=3/14 because each of 14 marbles is equally likely to be drawn.
Step-by-step explanation:
We have to write down some values that we can see from the graph. At x=0, the value is 100. At x=1, the y-value is 150 and at x=2 the graph has a value of a little over 200. We see also that this is an exponential graph, so we might assume that there is a specific ratio from each x-value to the next. We get that this ratio is 150/100=1.5. Hence, the quantity increases by 1.5 or 150% every time we add 1 to the x-coordinate. The 2 first sentences are correct. If an amount increases by 50% after a year, at the end of the year there is 150% of it (we need to add the initial capital which is 100%). Thus the graph here has as x-axis years and as y-axis money. The same concept holds for the 2nd sentence. The 3rd sentence is wrong because the value here is not multiplied but added. This would produce a linear graph. Sentence 4 has the wrong ratio; if that was true, then at x=1 we would have 200 oranges, not 150. For the same reason option 5 is wrong; 150*100=15000, not 150.
To find all the possible combinations, you will multiply all the choices together because you can groups each choice with any of the other.
4 x 6 x 2 x 3 = 144
There are 144 choices.
Think of the first option, you can combine 1 small toy with any of the other options for each toy.
Given:
Principal = $1400
Simple rate of interest = 1.25%
Time = 6 month
To find:
The balance of the account after simple interest.
Solution:
The formula for simple interest is
Where, P is principal, r is the rate of interest in % and t is time in years.
Time = 6 months
= year
= 0.5 year
Putting 1400, r=1.25, t=0.5 years.
Now, the amount is
Therefore, the balance of the account after the simple interest is $1408.75.
Answer:
10/31
Step-by-step explanation:
Out of the total 62 skaters, 20 were not age 12 and were wearing rollerblades. 20/62=10/31. Hope this helps!
