Answer:
a) 12/323
b) 8/233
Explanation:
 
a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323
b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233
 (hopefully I did this right)
 
        
             
        
        
        
The wheels will be completely used up and  it is the limiting reactant in this case.
<h3>What is a limiting reactant?</h3>
The limiting reactant is the reactant that is completely used up in a reaction, and thus determines when the reaction stops.
- 60 breaks will be used for 30 engines and 30 body frame
 - 80 wheels will be used for 20 engines and 20 body frame
 - 64 headlights will be used for 32 engines and 32 body frame
 
The wheels will be completely used up and  it is the limiting reactant in this case.

QPOE Files
The x-ray data are stored in QPOE files (Quick Position-Ordered Events, *.qp) rather than image arrays. These are lists of photons identified by several quantities, including the position on the detector, pulse height, and arrival time. Note that, unlike IRAF images, QPOE files have no associated header file, and are always stored in the current directory, unless explicitly specified otherwise. Non-PROS IRAF tasks can also access QPOE data files in place of image arrays.
 
        
             
        
        
        
All of them are soluble salt.
First one dissociates into two ions. 
The second one dissociates into 3 ions. 
The third dissociate into 4 ions. therefore, Al(NO3)3
        
             
        
        
        
The new trend will probably be the technology that's in that certain year. Like the trend in the modern days are all electronics or will have to do with electronics. Hope this helps! :) Pls mark me as the BRAINLIEST!!!
