We are usually concerned with one reaction. That is, the production of one specific set of products from a specific set of reactants.
The number of values of c/d would be the number of possible ways that a and b could recombine to form different pairs of products c and d. (You might get different reactions at different temperatures, for example. Or, you might get different pars of ions.)
Usually, the number of values of c/d is one (1). (Of course, if you simply swap what you're calling "c" and "d", then you double that number, whatever it is.)
Answer:
B) irrational. Since an irrational number cannot equal a rational number.
The premise that c is rational is false
Step-by-step explanation:
The assumption that c is rational means that the difference c-a must be rational. That difference is b, so b=c-a would mean that b must be rational. But b is defined to be irrational. Since an irrational number cannot equal a rational number, a contradiction arises and the assumption that c is rational must be false. Therefore the sum (c) must be irrational. (B)
Answer:
Option A , should not be rejected
Step-by-step explanation:
From the question we are told that:
Sample 1 
Standard deviation 1 
Sample 2 
Standard deviation 2 
Level of confidence 
Generally The Hypothesis are given as
Generally the equation for test Statistics is mathematically given by
Therefore
Critical Value
Where
Therefore
From Table
Therefore
Hence,We fail to reject the Null Hypothesis 
Option A , should not be rejected
<span>In a baseball season:
Peter hit = 2 (x - 6)
Total = 19 hits
X= Alex’s hit
Y = Peter’s Hit
=> Y = 2(x - 6)
=> x + y = 18
Let’s start from the second given equation:
=> x + y =18
=> y = 18 – x
Now, let’s use the first given equation to solve:
=> 18 – x = 2 (x - 6)
=> 18 – x = 2x – 12
=> -3x = -30
x = 10
Now, Let’s try:
=> Y = 2(x - 6)
=> y = 2 (10 - 6)
=> y = 2 (4)
=> y = 8
Thus, Peter hit 8 and Alice hit 10.</span>
