gulaghasi [49]3 years ago
7 0

Answer:

x + 4

Step-by-step explanation:

The question have missing details.

Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"

So, we assume that she has x bags of can before the picnic.

After\ Picnic = 4

So, the total number of bags collected is:

Total = Before + After\ Picnic

Total = x + 4

<em>If x is 5, then she took 9 bags of can to the recycling center</em>

<em>If x is 2, then she took 6 bags of can to the recycling center</em>

<em>If x is 0, then she took 4 bags of can to the recycling center</em>

Sue has 20 biscuits in a tin There are 12 plain biscuits 5 chocolate biscuits 3 currant biscuits Sue takes at 2 random biscuits
vagabundo [1.1K]

Answer:

111 / 190

Step-by-step explanation:

Total biscuits = 20

Plain, P = 12

Chocolate, C = 5

Currant, K = 3

Assume without replacement :

Probability that biscuit are of the same type :

P(plain) :

12 / 20 * 11 / 19 = 132 / 380

P(chocolate) :

5/ 20 * 4 / 19 = 20/ 380

P(currant) :

3/20 * 2 /19 = 6 / 380

Therefore,

Probability that biscuit is of the same type :

P(plain) + P(chocolate) + P(currant)

132/380 + 20/380 + 6/380

158 / 380 = 79 / 190

Therefore, probability that biscuit aren't of the same type :

1 - P(biscuit is of same type)

1 - 79/190

(190 - 79) / 190

111 / 190

Last week the coral reef grew .0196m

Step-by-step explanation:

So it's hard to explain but simply Milli witch is the symbol "m" is a unit prefix in the metric system denoting a factor of one thousandth (10 −3).  So 19.6mm is 19.6*10^-3m.  in other words 19.6 times 10^-3m

hope this helps sorry it's so complicated :/
