Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.

Seven blue and four red balls are to be arranged in order. How many ways can this be done if (1) The blue balls are distinguisha
Sav [38]

Answer:

1) n = 39916800

2) n = 1663200

3) n = 330

Step-by-step explanation:

1) If the blue balls are distinguishable as are the red balls

Then you can arrange these balls in the following ways, we must use a permutation

In totally we have 11 balls, then

n = 11P11

n = \frac{11!}{(11-11)!} = 11! = 39916800\\  

2) If Blue balls are distinguishable, but the red balls are identical

In this case, we need to do a correction due to the red balls are identical and we cannot identify the difference when we interchange two red balls

n = \frac{11!}{4!}  = \frac{39916800}{24} = 1663200

3) If the balls of each color are indistinguishable

We proceed equal to the before case but we include a correction due to blue balls also

n = \frac{11!}{4!*7!} = \frac{39916800}{24*5040} = 330
