Answer:
Yes, The events A and B are mutually exclusive event.
Step-by-step explanation:
Two chips are drawn at random and without replacement from a bag containing two blue chips and two red chips.
Total chips (n ) = 4
Two chips are chooses from 4 chips then the total possibilities are = 
total outcomes = 
= 6
Let 
and 
denote blue chips and 
and 
denote red chips.
A: {At least one of the chips is blue} = { 
, 
, 
, 
, 
}
P( A) = 
B: {Both chips are red} = { 
}
P( B) = 
= { 
, 
}
= 
If A and B are mutuall exclusive
= P( A) + P( B)
P( A) + P( B) = 
= 1
= = 1
Hence
= P( A) + P( B)
Then A and B are mutuall exclusive
Two hours bc if it takes 8 to do it in one hour and u split the number of men u have in half you double the work hours 8men=1hour of work 4men=2hours of work
Hope this helps have a nice day
The complete balanced chemical reaction is:
<span>C7H16 + 3O2
--> 7CO2 + 8H2O</span>
So 3 moles of oxygen O2 is required for every 1 mole of
C7H16. In the same manner, 3 molecules of O2 is required for every 1 molecule
of C7H16.
Answer:
<span>3 molecules O2 </span>
700 is 10 times as much as 70 since 70 times 10 equals 700.
70 is the answer
Hope this helps!
Answer:
1. 10 weeks
Step-by-step explanation:
Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.
... $6 × w = $60
Divide by $6 to get ...
... w = $60/$6 = 10
Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

<em>Comment on the problem statement</em>
The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)
