Answer:
The probability is 0.5086
Step-by-step explanation:
The probability P that at least one of these three modules will fail to work properly is calculated as:
P = 1 - P'
Where P' is the probability that all the modules works properly. So, P' os calculated as:
P' = 0.9 * 0.84 * 0.65
P' = 0.4914
Because 0.9 is the probability that module 1 works properly, 0.84 is the probability that module 2 works properly and 0.65 is the probability that module 3 works properly.
Finally, the probability P that at least one of these three modules will fail to work properly is:
P = 1 - 0.4914
P = 0.5086
Answer:
270 in
Step-by-step explanation:
the least amount of fabric she would need is equal to the area of the mat
the mat is in the shape of a rectangle
Area of a rectangle = length x width
15 x 18 = 270 in²
Answer:
y=5
Step-by-step explanation:
We know that Marcus spent 10 hours on his homework this week so:
10 hours = 100%
Marcus is saying that he spent 110% more time doing his homework this week, in comparison to last week.
Then to see if he is correct we have to find 110% of 10 hours.
So if: 100% of 10 hours = 10 hours
And: 10% of 10 hours (equivalent to 600 minutes) = 1 hour (or 60 minutes)
Then we add the two: 10 hours + 1 hour
And we get: 11 hours
As a result, Marcus is correct; he did spend 110% more time on his homework this week.
Hope this helps! :D
