Answer:
Step-by-step explanation:
If we are given two dependent events 
and 
such that their chances of occurrence or the probabilities of the events are: 
and 
.
Then the conditional probability that the event will occur given that has already occurred is given by the following formula:
Here the two events given are 
and 
.
and 
As per the above formula that we have already discussed, the formula can be written as:
She invested.. .say "a" amount on the 4% and "b" amount on the 5% one
now, she lost the 4% one or "a", so... that'd be a negative amount
now, we know both investments added together add up to 9000
and we also know the "net" receipts for the yield was 351, that simply means that whatever "b" and "a" yielded, ended up as 351
so.. what's 4% of a? well (4/100) * a or 0.04a
what's 5% of b? well (5/100) * b or 0.05b
since "a" was a loss(negative), then we know the net yield is => b - a = 351
thus
solve for "b", to see how much was invested at 5%
what about a? well, a = 9000 - b
Answer:
20
Step-by-step explanation:
Do 15 divided by 0.75
Answer:
24 ml oil
60 g onions
360 g potatoes
400 ml milk
Step-by-step explanation:
The recipe makes 16 portions and you only need 4 portions. Since 16 is 4 times bigger than what you need, just divide everything you've been given by 4.
<em>*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.</em>
1) 96/4 = 24 ml
2) 240/4 = 60 g
3) 1.44/4 = 0.36 kg
They want it in grams, so times it by 1,000 to convert. this gives you 360 g.
4) 1.6/4 = 0.4 l
They want it in ml, so times it by 1,000 to convert. this gives you 400 ml.
Hope this helped : )
