P(f | weekend) = p(f & weekend)/p(weekend)
.. = 10%/25%
.. = 0.4 = 2/5
P(volleyball and baseball) = 4/200 x 100 = 2%
P(volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.
Thus, 25% of students participate in either volleyball or baseball.
Answer:
and
expressed in interval notation.
Step-by-step explanation:
A compound inequality
has been provided. Our task is to determine the solution for this inequality.
Initially, we will address each inequality independently, followed by merging the findings by combining the overlapping intervals.



By dividing with a negative number, it is necessary to reverse the inequality sign:





Again, dividing by a negative requires flipping the inequality sign:


In combining both intervals, we will arrive at:

Thus, the solution for the inequality provided is
and
in interval notation.
Answer:
The solution to your inquiry can be found below
Step-by-step explanation:
First method
20 = 5(-3 + x) expanding this equation
20 = -15 + 5x combine like terms
5x = 20 + 15
5x = 35 dividing by 5
5x/5 = 35/5
x = 7
Second method
20/5 = 5/5 (-3 + x) divide both sides by 5
4 = -3 + x adding 3 to both sides
4 + 3 = -3 + 3 + x simplifying
7 = x
Llen missed 5 targets, which is due to -50 divided by -10 equaling 5. I hope this clarifies! <3
