- There are 130 people in a sport centre,
76 people use the gym,
60 people use the swimming pool,
32 people use the track,
23 people use the gym and the pool.
8 people use the pool and the track
20 people use the gym and the track,
6 people use all three facilities,
A person is selected at random
What is the probability that the person uses exactly one of the facilities?
Answer:
0.6462 = 64.62% probability that the person uses exactly one of the facilities
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
20 people use the gym and the track and 6 people use all three facilities
So 20-6 = 14 use exactly the gym and the track and 6 use all three.
8 people use the pool and the track
So 8 - 6 = 2 use exactly the pool and the track.
23 people use the gym and the pool.
So 23 - 6 = 17 use exactly the gym and the pool.
32 people use the track
So 32 - (6 + 14 + 2) = 10 use only the track.
60 people use the swimming pool
So 60 - (6 + 2 + 17) = 35 use only the pool.
76 people use the gym
So 76 - (6 + 14 + 17) = 39 use only the gym
What is the probability that the person uses exactly one of the facilities?
Out of 130, 39 + 35 + 10 = 84 use exactly one of the facilities.
84/130 = 0.6462
0.6462 = 64.62% probability that the person uses exactly one of the facilities
equation shows the relationship between X and why.
y= - 7 + 9
what is the slope of the equation?
Answer:
-7
Step-by-step explanation:
I am assuming that you meant y=-7x+9
so the the slope would be y=mx+b
so -7

the solution to a system of linear equations who has only one solution is always
A- a fraction
B- a coordinate pair
C- a negative number
D-a decimal
Answer:
The point where the two lines intersect is the only solution. An inconsistent system has no solution.
Step-by-step explanation:
you have to study
Answer:
[tex]\huge\colorbox{red}{B)a coordinate pair}[/tex]
Step-by-step explanation:
the solution to a system of linear equations who has only one solution is always a coordinate pairsee an example in the graph:
a system of linear equation which has a solution:
[tex]\begin{cases}x+y=5\\x-y=3\end{cases}[/tex]
we can see the graph of the system of linear equation that it one solution is a coordinate pair (4,1)
how do I round off 6.2 into a number
Ok so if you are rounding it to the nearest tenths place the answer would be 6
hope that's right!!
Answer:
well if you want to get to a whole number it would be 6
Step-by-step explanation:
you get that by well let's say it was 5.5 the second number is over half so it would round up to a whole of 6 but if it was 5.4 it would round down to 5.
I can explain better if needed

Mr. Carter is creating a sign for the football players to run through for the homecoming game. The scale of the
drawing and the scale are shown below. What is the area in square feet of the actual sign?
a. 13 square ft
b. 15.9 square ft
c. 18 square ft
d. 234 square ft
Answer:
D) 234 square ft
Step-by-step explanation:
The formula for area is: length x width.
The length is 9 in or (using the scale) 18 ft.
The width is 6.5 inches or (using the scale) 13 ft.
Multiply 18 x 13 to get 234 square ft.

y is 20 less than the
product of five and
half of x.
i need to know the rate of change
Answer:
You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)

What is the equation of the line whose slope is 1/3 and y-intercept is -4?
Question 1 options:
y=−4x+13
y=13x−4
y−4=13x
3y=−4x
Answer:
y=1/3x-4

the slope-intercept format of the line is y=mx+b, where m is the slope and b is the y intercept.
we are given the slope (1/3) and the y intercpet (-4).
substitute the numbers into the equation
y=1/3x-4
the answer is y=1/3x-4
