OK I DON'T KNOW THE ANSWER FREE POINTS THOUGH
Step-by-step explanation:
Answer:
x ≤ 9 or x ≥ 10
Step-by-step explanation:
2x + 7 ≥ 27
2x ≥ 20
x ≥ 10
or
3+ 3x ≤ 30
3x ≤ 27
x ≤ 9
Answer:
- The means for both data sets are equal.
- The range of the number of pages Lionel read is greater than the range of the number of pages Aaron read.
- The range of the number of pages that Lionel read is 75.
Step-by-step explanation:
Given
Lionel
90, 45, 30, 25, 15
Aaron
55, 19, 40, 16, 75
in the first case; For Lionel;
Mean = (90+45+30+25+15
)/5 = 41 and
Range = (90-15)=75
The second case; Aaron
Mean = (55+19+40+16+75)/5 = 41 and
Range = (75-16)= 59
Therefore;
Both data sets have the same mean but different range.
The range of the number of pages Lionel is 75, which is greater than the range of the number of pages Aaron read, which is 59.

Step-by-step explanation:
If A and B are two different events then, P(A U B) = P(A) + P(B) - P(A ∩ B)
Explanation of the formula:
If you look at the Venn Diagram, if you add 2 areas : P(A) and P(B), P(A ∩ B) is overlapping. This is why you should remove P(A ∩ B).
However, in this case, we should find P(A ∩ B) and all the other values are given in the question. Hence, we implement them and find P(A ∩ B).
