Question:
Select expression that is mathematically equivalent to

a) 
b) 
c) 
d) 
Answer:

Step-by-step explanation:
Given

Required
Determine its equivalent
Start by writing y - z in bracket;

becomes

When - is used as divide, it is equivalent to /
The given expression can then be rewritten as

Hence;
<em />
<em> is equivalent to </em>
<em />
1 foot because
2 times 3 = 6
60,000 times 6 = 360,000
Answer:
0.6443
Step-by-step explanation:
Given the that:
P(Z < 0.37) ; using a standard normal distribution :
The probability can be obtained using several methods :
Using a standard normal distribution table ;
P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table
Hence,
P(Z < 0.37) = 0.6443
