Answer:
ans = p=7
Step-by-step explanation:
10p-3=2(12+4p)-7
10p=24+8p-7-3
10p-8p=14
2p=14
p=14/2
<u>p=7</u>
Answer: 57%
Step-by-step explanation:
Answer:

Step-by-step explanation:
Total number of people = 130
Number of people who use the gym = 73
Number of people who use the pool = 62
Number of people who use the track = 58
Number of people who use the gym and the pool = 22
Number of people who use the pool and the track = 29
Number of people who use the gym and the track = 25
Number of people who use all three facilities = 11
Total number of people who use at least two facilities = 22 + 29 + 25 + 11 = 87
The probability that the randomly selected person uses all three facilities = number of those who use all three facilities ÷ total number of people who use at least two facilities.
==> 11 ÷ 87
==> 
Answer:
rate of change is -3
A = (9 - 0) / (0 - 3) = 9 / -3 = -3
Step-by-step explanation:
Perpendicular = opposite sign and reciprocal slope
Make equation into y = mx + b
Add 3y to both sides
3y + 54 = 3x
Subtract 54
3y = 3x - 54
Divide by 3
y = x - 18
The slope is 1
Make it negative and reciprocal
= -1/1 = -1
Solution: the slope will be -1
