Perpendicular line intersect at a 90 degree angle
<span />
For this graph the equation is x= -3
Because in the coordinates you gave, all the x values are -3 telling me that the line is a straight vertical line passing through the -3 x-axis and has no y-intercept as it's a vertical line, not diagonal, so it's not passing through the y-axis. Plus because of this too this line has no gradient.
Answer:
a.) x+12
b.) x-15
c.) 4x+7
2.) the following expression are equivalent because 5 multiplied by 2n would be 10n and then the rest of the expressions are similar.

Answer:
Normal distribution.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes 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:
Samples larger than 30, which means that the sampling distribution for the sample proportion follows a normal distribution.
