Answer:
c. normal probability distribution
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
In this question:
By the Central Limit Theorem, it is a normal distribution, so option c.

Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
13x + 34° + 10x + 10° = 90°
=> 13x + 10x = 90° - 34° - 10°
=> 23x = 46°
=> x = 46°/23 = 2°
