Answer:
number of hours = 3 hours
Step-by-step explanation:
Let
x = number of hours
Casa Lucia = 200 + 500x
Silver Fox = 1,100 + 200x
To solve the equation, equate both cost of rent
Casa Lucia = Silver Fox
200 + 500x = 1,100 + 200x
200 - 1,100 = 200x - 500x
-900 = - 300x
x = -900 / -300
x = 3 hours
number of hours = 3 hours
The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.
It means both locations cost the same if rented for 3 hours each

Answer:
PB=5
Step-by-step explanation:
Since you know that BD=24, you also know that both segments BC and CD have the same value since they're congruent: 12. You also were given the value of PC. Using Pythagorean Theorm, Substitute 12 for a and 13 for c, so the equation would say
12^2+b^2=13^2
Simplify to get
144+b^2=169
Now subtract 144 from 169 and you get 25. That is b^2. All you have to do now is square root 25 to isolate b.
√25=5
So therefore,
b=5
Answer:
Population mean = 21
Margin of error = 4
Step-by-step explanation:
Given that
Lower bound of the population is 17
Upper bound of the same population is 25
The population mean, x-bar is calculated by saying
x-bar = (lower bound + upper bound)/2
x-bar = (17 + 25)/2
x-bar = 42/2
x-bar = 21
Margin of error for the confidence interval is gotten by
E = (upper bound - lower bound)/2
E = (25 - 17)/2
E = 8/2
E = 4
Thus, the mean is 21, while the error is 4
