Step-by-step explanation:
The system of equations representing the number of Blue-ray discs and DVD's after t months are:
507 + 26t
925 - 12t
Each month, the number of DVD's sold decreases by 12, this can be modelled as:
number of DVD in opening month - (monthly decrease x number of months)
Number of DVD's in t months = 925 - 12t
Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:
number of blue-ray discs in opening month + (monthly increase x number of months)
Number of Blue-ray discs in t months = 507 + 26t

Answer:
Step-by-step explanation:
Well let's get a couple of equivalents and you can pick the one you like best.
You could have (5 * 3)/4 = 15/4
This 15/4 will give you 3.75
You could have (2*15)/ (2*4) = 30/8 Multiply top and bottom by 2.
30/8 = 3 6/8 = 3 and 3/4
What is the interquartile range of the data? With the numbers 2,3,3,4,5,7,8,8,8,10,10, and 12
harina [27]
Answer:
The interquartile range = 5.5
Step-by-step explanation:
Given the data
2 3 3 4 5 7 8 8 8 10 10 12
As we know that
The interquartile range is the difference between the third and first quartiles.
- The first quartile is the median of the bottom half of the numbers.
So, to find the first quartile, we need to place the numbers in value order and find the bottom half.
2 3 3 4 5 7 8 8 8 10 10 12
So, the bottom half is
2 3 3 4 5 7
The median of these numbers is 3.5.
- The third quartile is the median of the upper half of the numbers.
So, to find the third quartile, we need to place the numbers in value order and find the upper half.
2 3 3 4 5 7 8 8 8 10 10 12
So, the upper half is
8 8 8 10 10 12
The median of these numbers is 9
so
The third quartile is 9.
The first quartile is 3.5.
The interquartile range is the difference between the third and first quartiles.
The interquartile range = 9 - 3.5 = 5.5
Therefore, the interquartile range = 5.5
Answer:
angle NQT equals angle STR
Step-by-step explanation:
You already have two angLes, you just need a side to be able to say the AAS Theorem. The answer is the remaining side to figure that out
