P(z < x) = 0.6064 - 0.5 = 0.1064
From the normal distribution table
P(z < 0.27) = 0.1064
Therefore the z-score is 0.27
I can't explain it very well for you, sorry.

Answer:
We need to sample at least 1069 parents.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How many parents do you have to sample?
We need to sample at least n parents.
n is found when 
. So
Rounding up
We need to sample at least 1069 parents.
Answer:
x = 10
y = 14
Step-by-step explanation:
Here, we want to get the values of x and y
Since all sides are equal, the internal angle is 60 degrees for each internal angle
Since AC = 14
Then y is also 14 since what we have is an equilateral triangle
Secondly ;
6x = 60
x = 60/6
x = 10
