Matrix Dimension. The number of rows and columns that a matrix has is called its dimension or its order. By convention, rows are listed first; and columns, second. Thus, we would say that the dimension (or order) of the matrix below is 3 x 5, meaning that it has 3 rows and 5 columns.

Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
If this helped, I would appreciate it if you marked me brainliest. Have a nice day!
Given that normally distributed data set has a mean of 55 and 99.7% of data fall between 47.5 and 62.5.
Let s be the standard deviation of data set.
Since 99.7% data fall within 3 standard deviations of mean, z-value for 47.5 and 62.5 has an absolute value of 3.
That is |z|=3
But z= 
Let us plugin x=47.5 and mean =55 and equate it to 3.
That is 
Since x is always positive ( being standard deviation), 
Hence 
We will get same value with 62.5 as well.
Hence standard deviation of data set is 2.5.
