Since Q and R are independent, this means P(Q and R) = P(Q)*P(R)
<span>P(Q and R) = P(Q)*P(R)
</span><span>P(Q and R) = (4/5)*(4/11)
</span><span>P(Q and R) = (4*4)/(5*11)
</span>P(Q and R) = 16/55
Answer:
She would have to work for 33 hours.
Step-by-step explanation:
239.25/7.25=33. Since we are going with hours, this would be 33.
The next 3 numbers to be highlighted would be 90, 99, and 108.
multiples of 9 is like take 1 times 9 and 2 times 9 and etc.
or you can just keep adding on 9 from the previous number like 81 + 9= 90
Well 42 divided by 2 is 21. than to double check you can do 21 plus 21 equals 42.
