The equivalent set will be <u>A U B = {1, 2, 4, 5, 6, 8}</u>

<h3>Set theory</h3>

Given the following sets

U = {1, 2, 3, 4, 5, 6, 7, 8},

A ={2, 4, 6},

B = {1, 2, 5, 8},C = {1, 3, 7}

Required sets

A U B

Since union means that we are to write out all the values in the set A and B, hence the equivalent set will be;

A U B = {1, 2, 4, 5, 6, 8}

A standardized​ exam's scores are normally distributed. In a recent​ year, the mean test score was 1491 and the standard deviati
Alinara [238K]

Answer:

z(1910)=1.3429\\\\z(1230)=-0.9006\\\\z(2190)=2.2404\\\\z(1380)=-0.3558

Step-by-step explanation:

-Given the population mean is \mu=1491and  the standard deviation is \sigma=312, we calculate the z-scores using the formula:

z=\frac{\bar x-\mu}{\sigma}

#The z-score for 1910 can be calculated as:

z(1910)=\frac{x-\mu}{\sigma}\\\\=\frac{1910-1491}{312}\\\\=\frac{419}{312}\\\\=1.3429

#The z-score for 1230can be calculated as:

z(1230)=\frac{x-\mu}{\sigma}\\\\=\frac{1230-1491}{312}\\\\=\frac{-281}{312}\\\\=-0.9006

#The z-score for 2190 is calculated as follows:

z(2190)=\frac{x-\mu}{\sigma}\\\\=\frac{2190-1491}{312}\\\\=\frac{699}{312}\\\\=2.2404

#The z-score for 1380 is calculated as:

z(1380)=\frac{x-\mu}{\sigma}\\\\=\frac{1380-1491}{312}\\\\=\frac{-111}{312}\\\\=-0.3558
