In each quantity of 87 cg, 1 of them is active ingredient. In the quantity of interest,
... (1/87)·522 cg = 6 cg . . . is active ingredient
The remainder of that quantity, 516 cg, is inactive ingredient.
Answer:
1.875
Step-by-step explanation:
To find the expected winnings, we need to find the probability of all cases possible, multiply each case by the value of the case, and sum all these products.
In the die, we have 6 possible values, each one with a probability of 1/6, and the value of each output is half the value in the die, so we have:
Now, analyzing the coin, we have heads or tails, each one with 1/2 probability. The value of the heads is 2 wins, and the value of the tails is the expected value of the die we calculated above, so we have:
Answer:
Step-by-step explanation:
The smaller rectangle has a perimeter of 200 meters. Let's say that the smaller rectangle has length 60 and width 40. This would give it a perimeter of 200, since 2*(60+40) = 200.
If these are the length and width of the smaller one, we can multiply each by 5/4 to get the length and width of the larger one.
length of larger rectangle = 60*5/4 = 75
width of larger rectangle = 40*5/4 = 50
These dimensions would give a perimeter of 250, since 2*(50 + 75) = 250.
It is worth noticing that 250 is equal to 200 * 5/4. In the future, you can simply multiply perimeter by the ratio instead of going through all these steps.
Answer:
7,200
Step-by-step explanation:
Simply multiply 48,000 by .05, which equals 5%, and multiply that answer by 3, the amount of years.
If you would like to know what is the value of x - 10 when x = 35, you can calculate this using the following step:
x = 35
x - 10 = 35 - 10 = 25
The correct result would be A. 25.
