Answer:
(4, 5 )
Step-by-step explanation:
x + y = 9 → (1)
x - y = - 1 → (2)
adding the 2 equations term by term will eliminate y
2x + 0 = 8
2x = 8 ( divide both sides by 2 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
4 + y = 9 ( subtract 4 from both sides )
y = 5
solution is (4, 5 )
get a journal and pencil and when you go to sleep, don't put on any alarms. then write down in the morning what you dreamt about. every detail you can thing of. if you have the dream again, write down more details. this will help you begin to lucid dream.
The length of each interval would be 3.75 rounding to whole number is 4.
Step-by-step explanation:
- Stack in excel from lowest to highest points.
- Total number of data points are 14.
- Frequency distribution to be created.
- You can use countif function for frequency distribution.
- Since we have already got the number of intervals.
- It will be easier to calculate the number if intervals.
- normally there should be 5-15 intervals to get a better histogram.
- Basic formula is Highest data point - Lowest data point/ classes/intervals.
- So (29-14)/4 = 3.75 rounding to 4.
When you divide both sides by 5
