Using the normal distribution, it is found that the third quartile is of Q3 = 0.67, hence option B is correct.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 0ºC, hence .
- The standard deviation is of 1ºC, hence .
The third quartile is X when Z has a p-value of 0.75, as , hence <u>X when Z = 0.67.</u>

Y = 7/2x + 3 is the slope-intercept form
The answer is not defined.
Explanation:
The given matrix is
The matrix has dimensions
This means that the matrix has 2 rows and 2 columns.
Also, the matrix has dimensions
This means that the matrix has 2 rows and 1 column.
Since, the matrices can be added only if they have the same dimensions.
In other words, to add the matrices, the two matrices must have the same number of rows and same number of columns.
Since, the dimensions of the two matrices are not equal, the addition of these two matrices is not possible.
Hence, the addition of these two matrices is not defined.
The formula is rad (-6-(-3))^2 + (7-0)^2 which equals 7.6
