They are asking what direction is it from point A to point B. hope that helps
Answer:

Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are
number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is
=6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is
. (Answer)
For Question Number one
(2+10)²+4=148
Question Number two:
(6+5)×(8-6)=22
1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5
2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4
probability both balls are blue : 3/5 * 1/4 = 3/20 <==
Answer:
The answer is the last one.
Step-by-step explanation:
Firstly, look at the first inequality and we get
, so
. In the second inequality, we have
, so
. Together, we know that the answer is the last one.
