Answer:
z = 1.095
Step-by-step explanation:
To calculate the value of z, it is to replace in the corresponding formula:
z = (x - m) / sd
where m, which is the mean, which has the value of 17.7
x, the sample, which would be 20
and sd the standard deviation, which is equal to 2.1
Now by replacing all the values:
z = (20 - 17.7) /2.1
z = 1.095
Answer: B
Step-by-step explanation: there are countless amounts of ways you can organize them or stack them
You find a parallelogram area by this formula:
Where
b is its base and
h, its height.
You get
b's value applying distance between two points formula.
If A and B points form the base:
And
h is the perpendicular distance between both bases.
