Answer:
0.23
Step-by-step explanation:
less than 0.24 and greater than 0.007
Answer: M is the angle.
Explanation: If you look at it, A+B+C+D can equal a few things, but you mostly get (M) because m L BEA =62^• may be true. But it equals m
Step-by-step-helper: A+B+C+D=? A+B=b over a, so C+D= d over c. M+__=? just m. So the answer is m.
In this case, the ladder formed a triangle with the wall, you can see it in the attached diagram.
Let the distance of ladder from base of wall = x
Now to find the value of x, we use cosine ratio.
cos ∅= Adjacent / Hypotenuse
Put values
cos72= x/15
15 cos 72 = x
or
x=15 cos 72
x=4.6 ft ( Rounded to nearest tenth)
So, the distance of ladder from base of the wall is 4.6 ft.
I hope this helps you
-x+4=2x+1
4-1=2x+x
3=3x
x=1
y=-1+4
y=3
Answer:
Engineer 1
Step-by-step explanation:
Based on the information given:
P( 1 ) = 0.7
P( 2 ) = 0.3
P(A | B) is a conditional probability: the likelihood of event A occurring given that B is true.
P( E | 1 ) = 0.02
P( E | 2 ) = 0.04
Then P( E | 1 ) is the probability that an error occurs when engineer 1 does the work and P( E | 2 ) is the probability that an error occurs when engineer 2 does the work.
To have an idea of which engineer is more likely to do the work when an error occurs you need to calculate P( 1 | E ) and P( 2 | E ), The probability that engineer 1 does the work when an error occurs and the probability that engineer 2 does the work when an error occurs.
The Bayes's theorem states:
Using the notation above:
P( E ) = 0.7*0.02 + 0.3*0.04 = 0.026 /// the probability that engineer 1 does the work and an error occurs or the probability that engineer 2 does the work and an error ocurrs.
Doing the same for engineer 2:
