Answer:
8 sand bags can be carried along.
Step-by-step explanation:
First you want to subtract 300-140. That subtracts the pilots weight giving you the maximum weight capacity left. (160) Then you want to divide 160 (the weight that can be carried) by 20 (the weight of the sand bags) after doing that you will get 8. And that is how i got 8 sand bags as my answer.
Take it and divide it by 5, or you can multiply it by .2
Answer:
Following are the answer to this question:
Step-by-step explanation:
In the question first calls the W if the transmitted chip was white so, the W' transmitted the chip is red or R if the red chip is picked by the urn II.
whenever a red chip is chosen from urn II, then the probability to transmitters the chip in white is:

The probability that only the transmitted chip is white is therefore
, since urn, I comprise 3 chips and 2 chips are white.
But if the chip is white so, it is possible that urn II has 4 chips and 2 of them will be red since urn II and 2 are now visible, and it is possible to be:


Likewise, the chip transmitted is presumably red
and the chip transferred is a red chip of urn II
, and a red chip is likely to be red
.
Finally, 

The estimation of
and
as:

Answer: 400 adult tickets were sold.
Step-by-step explanation:
Let x represent the adult tickets that were sold.
Let y represent the number of children tickets that were sold.
1000 tickets were sold to the seaport aquariums dolphin show. This means that
x + y = 1000
Adult tickets cost $10. Children tickets cost two dollars and a total of 5200 was collected. This means that
10x + 2y = 5200 - - - - - - - -1
Substituting x = 1000 - y into equation 1, it becomes
10(1000 - y) + 2y = 5200
10000 - 10y + 2y = 5200
- 10y + 2y = 5200 - 10000
- 8y = - 4800
y = - 4800/ - 8
y = 600
x = 1000 - y = 1000 - 600
x = 400
