P(4)= 1/8
This is because there are 8 equal parts and 4 is just one of those 8 parts.
Answer:
19,23
Step-by-step explanation:
9+x-7≥ 21
Combine like terms
2+x≥21
Subtract 2 from each side
2+x-2 ≥21-2
x≥19
Any number greater than or equal to 19
23.536 54.653 it is decimal form
Answer:
(2,1)
Step by step explanation:
Please find the attachment.
We have been given that line
is horizontal and passes through point (1,1). Line
is vertical and passes through point (2,2). We are asked to find point of intersection of line
and line
.
Line
is a horizontal line so y-coordinate will be 1 for any value of x. Line
is a vertical line, so x-coordinate will be 2 for any value of y.
Therefore, intersection point of both lines will include x-coordinate of line
and y-coordinate of line
that is (2,1).
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
