When the events are independent
P(A∪B) = P(A) + P(B) - P(A∩B) . . . . where P(A∩B) = P(A)·P(B)
Substituting the given numbers, you have
P(A∪B) = 0.3 + 0.9 - 0.3·0.9
P(A∪B) = 0.93
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y=x+2.05
This is a linear equation ( equation of a line)
To graph the line find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
For x=0
y=0+2.05=2.5
The y-intercept is the point (0,2.05)
<u>The x-intercept</u> is the value of x when the value of y is equal to zero
For y=0
0=x+2.05
x=-2.05
The x-intercept is the point (-2.05,0)
To graph the line plot the intercepts and then join the points
using graphing tool
see the attached figure
N=1.2 I don't know what you are asking in the second part of the question
Answer:
In a pulley, the ideal mechanical advantage is equal to the number of rope segments pulling up on the object. The more rope segments that are helping to do the lifting work, the less force that is needed for the job.
The answer is 54 pi in^3. All you have to do is multiply 3x3, then multiply that by 6 and you get the answer 54.
