Answer:
84%
Step-by-step explanation:
What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.
We have that z is equal to:
z = (x - m) / (sd)
x is the value to evaluate, m the mean, sd the standard deviation
So for 190000 we have:
z = (190000 - 200000) / (10000)
z = -1
and this value represents 0.1587
for 230000 we have:
z = (230000 - 200000) / (10000)
z = 3
and this value represents 0.9987
we subtract:
0.9987 - 0.1587 = 0.84
Which means that it represents 84% of the houses
Given:
The table that shows the relationship of the total number of pieces of fruit to the number of bananas.
To find:
Why is not equivalent to
.
Solution:
If a, b, c are real numbers, then
The given fraction is . It can be written as:
The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be , not
.
Therefore, the correct option is A.
