Answer:
The data is skewed left
Less than
Median is 22
mean is 20.2
Step-by-step explanation:
<u>median: 15,16,18,19</u>,22,22,<u>22,22,23,23</u>
mean: 15+16+18+19+(22x4)+(23x2)=
31+37+88+46=
68+134=202÷10=20.2
Answer:
(x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
Step-by-step explanation:
Here, we have to choose the sets from options which has a solution set of {x I x = 0}
From the given options it is clear that the second option will be the correct option.
Here, (x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
⇒ (x ≤ 0) ∩ (x ≥ 0)
Therefore, the only set of the above intersection of the two sets will be x = 0. (Answer)
The error is in step 2. -x and 3x combine to make 2x, not 4x
