Answer:
4.74 hours
Step-by-step explanation:
Given that both person have to place same number of rivets that is
11209
first person take 9 hours to complete the work
hence 1 hour work of 1st person is
of total work
second person takes 10 hours to complete the same work
hence 1 hour work of 2nd person is 
Now if both work together then
1 hour work of both person =
=
thus working together they need
hours = 4.74 hours to complete the whole work which is placing 11209 rivets
Answer:
71%
Step-by-step explanation:
Conditional Probability: <u>P(A and B)</u>
P(A)
P(A and B): 0.5
P(A): 0.7
=0.5/0.7
=0.71428... (x 100)
Answer:
11/30 or 0.36
Step-by-step explanation:
Given:
The slope of the line is -3.
The line passes through the point (2,-2).
To find:
The point-slope form of the line.
Solution:
Point slope form: If a line passes through the point
with slope m, then the point-slope form of the line is:

The slope of the line is -3 and it passes through the point (2,-2). So, the point-slope form of the line is:


Therefore, the required point slope form of the given line is
