- 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?
Answers
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

if f(x-3)=7x+4 for all values of X what is the value of f(-7)
Answers
Answer:
-66
Step-by-step explanation:
We have the expression f(x-3) = 7x + 4, in which for x the value is -7.
To solve first substitute x next to f(x).
f((-7) - 3) = 7x + 4
(-7) - 3
f(-10) = 7x + 4
Now that we know x is equal to -10, you may substitute to the actual equation.
f(-10) = 7(-10) + 4
f(-10) = -70 + 4
f(-10) = -66
9514 1404 393
Answer:
-24
Step-by-step explanation:
We want to evaluate the function when ...
x -3 = -7
x = -4 . . . . . add 3
Then, ...
f(-7) = f(-4-3) = 7(-4) +4
f(-7) = -24
__
Alternatively, we can rewrite the function to be f(x).
f(x) = f((x+3) -3) = 7(x +3) +4
f(x) = 7x +25
Now, f(-7) is ...
f(-7) = 7(-7) +25 = -49 +25
f(-7) = -24

1) x=8, y=138
2) x=110
Step-by-step explanation:
Answer:
1. x = 8, y =138
2. x = 110
Step-by-step explanation:
First we will need to find the value of x.
Since, I feel like being a kindergartener I'll do it the long way.
(5*2+2)+(6*2)
12+12
24
That wouldn't work
(5*8+2)=(6*8)
42+48=90
Therefore x = 8
Since we know 42 would be 42 degrees and it is a straight angle for both 5x+2 and y.
We would subtract 180-42=138.
Therefore, y = 138
2 would be simple. All we need to do is add 80+30=110 then subtract it by 180
180-110=70. Since x and the 70 degrees equal 180 degrees.
180-70=110
Therefore, your answer would be x= 110

PLEASE HURRY! this is financial algebra
Answers
Answer:
6 years
Step-by-step explanation:
Simple interest= P.R.T
I = $1300
P = 18000 deposit
Rate = 1.19%
T = ?
Putting into the formula we have
1300 = 18000x1.19/100xT
1300 = 18000x0.0119xT
1300 = 214.2T
Divide through to get T
T = 1300/214.2
= 6.069
So when we approximate T = 6 years
It would take 6 years to make $1300 in interest
