Assume (a,b) has a minimum element m.
m is in the interval so a < m < b.
a < m
Adding a to both sides,
2a < a + m
Adding m to both sides of the first inequality,
a + m < 2m
So
2a < a+m < 2m
a < (a+m)/2 < m < b
Since the average (a+m)/2 is in the range (a,b) and less than m, that contradicts our assumption that m is the minimum. So we conclude there is no minimum since given any purported minimum we can always compute something smaller in the range.
7 + 28n + 4
28n + (7 + 4)
28n + 11
Answer: option D
Step-by-step explanation:
X+8=-2
x= -2-8 (you should make x the subject so you switch the +8 to the other
x= -10 side which becomes -8)
so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D
The roll of the biscuit is 101/2 inches long. It has to be cut into slices that are 3/8 inches thick.
Then
The number of slices = (101/2)/(3/8)
= (101/2) * (8/3)
= 808/6
= 404/3
= 134.66
So the biscuit dough can be cut into 134 slices approximately. A small part will be left.
This is the only way to find out the number of slices the
biscuit dough can be sliced into. Hope this helps you in understanding the way
it is done.
Answer:
Step-by-step explanation:
- is the application of probability theory, a branch of mathematics, to statistics, as opposed to techniques for collecting statistical data.
- the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data.
