<span>So we wan't to see how long would it take to clean 5 showers if the time it takes to clean one shower is 5.22 mins. Lets say that the complete time that it takes to clean all showers is equal to x. then x would be: x=5*5.22mins. So we get: x=26.1 min. So the time it takes to clean all 5 showers is 26.1 mins. </span>
Answer:
5000
Step-by-step explanation:
650 is 13% of the day's production.
650 = 0.13 × n
n = 5000
Answer:
0.9 = 90% probability that it arrived during the last 30 seconds of the 5-minute period.
Step-by-step explanation:
The car is equally as likely to arrive during each second of the interval, which means that the uniform distribution is used to solve this question.
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distribution has two bounds, a and b, and the probability of finding a value higher than x is given by:
5-minute period
This means that
Find the probability that it arrived during the last 30 seconds of the 5-minute period.
300 - 30 = 270. So
0.9 = 90% probability that it arrived during the last 30 seconds of the 5-minute period.
Step-by-step explanation:
(x - 3)/x = -8/(x + 3) , x ≠ 0 or -3
(x - 3)(x + 3) = -8x
x² - 9 = -8x
x² + 8x - 9 = 0
x² + 9x - x - 9 = 0
x(x + 9) - 1(x + 9) = 0
(x + 9)(x - 1) = 0
x = -9
x = 1
x ≠ 0 or -3
-9 ≠ 0 or 3 PROVED
x ≠ 0 or -3
1 ≠ 0 or -3 PROVED
<h3>Value of x is -9 and 1</h3>
