Answer:
0.45 = 45% probability that the member uses the golf course but not the tennis courts
Step-by-step explanation:
I am going to solve this question using the events as Venn sets.
I am going to say that:
Event A: Uses the golf courses.
Event B: Uses the tennis courts.
5% use neither of these facilities.
This means that
75% use the golf course, 50% use the tennis courts
This means, respectively, by:
Probability that a member uses both:
This is . We have that:
So
What is the probability that the member uses the golf course but not the tennis courts?
This is , which is given by:
So
0.45 = 45% probability that the member uses the golf course but not the tennis courts
First, let's start by figuring out how much Kendra gets paid per day. To do this, we can divide 300 by 5. 300 / 5 equals $60 per day.
Next, we can take the amount she gets paid per day and multiply it by the number of days, 24. 24 * 60 = $1440.
At the rate of $60 per day, Kendra will get paid $1440 for working 24 days.
Hope this helps!! :)
The equation is
dvided by
6-0
= 6/-3= -2
-3-0
once you have your slope you plug in one of the coordinates and the slope into y=mx+b
I used (0,0)
0=-2(0)+b
0=0+b
0=b
your y int is 0
your equation would be y=-2x+0
V - the crew rowing rate,
u - rate of the current.
Downstream: v + u = 13.5/1.5 = 9 mph
Upstream : v - u = 13.5/4.5 = 3 mph
u = 9 - v
v - ( 9 - v ) = 3
v - 9 + v = 3
2 v = 12
v = 6 mph, u = 9 - 6 = 3 mph
Answer: the crew`s rowing rate is 6 mph and the rate of the current is 3 mph.
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
