Answer:
The key to this question is converting all the mass units to the same unit and adding them all up.
The only value that isn't consistent with the other units is 450 gm or grams.
Recall that 1 gram is equal to 0.001 kilo grams. So if you want to convert grams to kilograms you would multiply that amount by 0.001 or 1/1000

Now let's add up all the masses.

(Now a few footnotes here, that I considered but wasn't sure about. The answer asks for weight, but you're only given mass to work with. That would be fine, if the question asked you to convert it to SI weight units like Newtons, but there's no mention of that. And also I'm not sure if the question requires significant digits. But I'll continue the answer if you think so)
To convert this into weight in Newtons, multiply by 9.81 m/s^2

It would be doubled i think actually no just do the same equation with 4. i need to see the question first
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
The question is an illustration of probability, and the value of P(B|C) is P(B|C) = 9/24 =0.38
<h3>How to determine the probability P(B|C)?</h3>
The table is given as:
C D Total
A 15 21 36
B 9 25 34
Total 24 46 70
The probability (BIC) is calculated using:
P(B|C) = n(B and C)/n(C)
From the table, we have:
n(B and C) = 9
n(C) = 24
So, the equation becomes
P(B|C) = 9/24
Evaluate
P(B|C) = 0.38
Hence, the value of P(B|C) is P(B|C) = 9/24 =0.38
