Answer:
0.13
Detailed explanation:
In a bag containing 5 nickels, 8 dimes, and 7 quarters, we randomly select 5 coins at once.
This means we need to pick 2 nickels from the 5 available, 2 dimes from the 8, and 1 quarter from the 7 quarters.
In total, there are 5 + 8 + 7 = 20 coins.
Selecting 5 coins from the entire set of 20 coins.
2 nickels can be chosen from 5 in 5C2 ways.
2 dimes can be taken from 8.
1 quarter from 7 quarters.
5 coins chosen from 20.
The probability of obtaining 2 nickels, 2 dimes, and 1 quarter is given by:
I may be mistaken, but I believe it's (1,2Π3-1)
Let's convert each statement into mathematical terms.
Pineapple = p
Orange = x
is indicates equality
Pineapple has a weight that is 7 times that of an orange: p = 7x
Pineapple is 870 grams heavier than the orange. p = 870 + x
Insert p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
Divide by 6
x = 145
The weight of the orange is 145 grams.
The weight of the pineapple is 7 times that of the orange = 7(145) = 1015 grams.
