Ok so u have to multiply for this one
Work *Jake*:
So he spends 2 hours on each assignment. He has 3 assignments so u have to do :
2*3=6
He spend 6 hours a day doing home work so now u have to multiply that by 30:
6*30=180
Work *Orlando*:
So he spends 2 hours on each homework. He has 2 sheets each do so u have to multiply 2 and 2:
2*2=4
He spends 4 hours a day doing homwork so u have to multiply it by 30:
4*30=120
Answer:
So Jake spends 130 hours
Orlando spends 120 hours
Add both together:
120+130=250
They spend 250 hours together on work in 30 days/
The answer is f^-1(x)=8/3+x/3
Answer:

Step-by-step explanation:
Given that in a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about their past travel experience.
Since the two are drawn without replacement the first trial affects the second trial. In other words, each trial is not independent of the other.
a) Hence this cannot be binomial experiment. The reason is p=probability for each trial is not constant as first draw affect the probability for Ii draw
b) The probability that in a random sample of 2, no one has been abroad
=Prob of selecting both people from the group where no one has been abroad
We have in the group 35% i.e. 14 people never been to abroad
So required probability = Prob of selecting both from 14 people
=
14 and 7 are the two next terms
