Pls give the question to expect that u get answers from others
Thank u
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
Answer:
Below because there is a lot to explain
Step-by-step explanation:
The Minimum of the data set is 20 and the maximum is 75, the median of the data set is 50, and the interquartile range is 30. The data is most likey asymetrical due to the average being median and not mean. Hope this helps :)
