Answer: 0.379

Step-by-step explanation:

Given : Total oranges =60

Rotten oranges = 6

Number of fresh orange = 60-6=54

Sample size : n=5

Customer picks up 5 oranges from total 60, then the probability that first orange is fresh =\dfrac{54}{60}

Probability that next orange is fresh= \dfrac{54-1}{60-1}=\dfrac{53}{59} and so on.....

The probability that more than one are rotten :-

1-\text{P(no rotten)}\\\\=1-\dfrac{54\times53\times52\times51\times50}{60\times58\times57\times56\times55}\\\\=1-0.621166945577\\\\=0.378833054423\approx0.379

Chances of one or more = 1 - chance of no rotten oranges

chance of no rotten oranges = 54/60 * 53/59 * 52/58 * 51/57 * 50/56

natali 33 [55]

First step

You must stablish a relation  

150 ml sauce/100 ml vinegar

If   100 ml vinegar_______150ml sauce  then  11 ml vinegar ____x ml sauce

Second step

You must resolve x from the equation  

X= (11ml vinegar*150 ml soya)/(100 ml vinegar)= 16.5 ml sauce, it means that it will be  16,5 ml sauce by every 11 ml  of vinegar

Heck did I do wrong!?!?! IXL sucks
zysi [14]

Answer:

∠G, ∠HGI, ∠IGH

Step-by-step explanation:

» <u>Concepts</u>

To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex <u>is not </u><u>I</u>.
