Answer:
9/23
Step-by-step explanation:
Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.
___
Let A represent basketball, and B represent baseball. Then ...
P(A or B) = P(A) +P(B) -P(A and B)
Since 8 students play neither sport, we have ...
1 -8/23 = 11/23 +13/23 -P(A and B)
15/23 = 24/23 -P(A and B)
P(A and B) = (24 -15)/23
P(A and B) = 9/23
Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
we know that
The solution for x is the interval ----> (5,8)
All real numbers greater than 5 and less than 8
Part 1) Find all possible values of the expression 6x
so
For x < 8
The expression value is 6x < (6)(8) -----> 6x < 48
For x > 5
The expression value is 6x > (6)(5) -----> 6x > 30
therefore
Part 2) Find all possible values of the expression -10x
so
For x < 8
The expression value is -10x > (-10)(8) -----> -10x > -80
For x > 5
The expression value is -10x < (-10)(5) -----> -10x < -50
therefore
Part 3) Find all possible values of the expression x-5
so
For x < 8
The expression value is x-5 < 8-5 -----> x-5 < 3
For x > 5
The expression value is x-5 > 5-5 -----> x-5 > 0
therefore
Part 4) Find all possible values of the expression 3x+2
so
For x < 8
The expression value is 3x+2 < 3(8)+2 -----> 3x+2 < 26
For x > 5
The expression value is 3x+2 > 3(5)+2 -----> 3x+2 > 17
therefore
