Answer:
-17
Step-by-step explanation:
-2^3 - 3^2
= -8 - 3^2
= -8 - 9
= -17
Answer:
305
Step-by-step explanation:
This sequence es the sum of 3
5+3 =8
8+3 = 11
then
101 = 100 + 1
the fisrt date is 5
the another 100:
100*3 = 300
300 + 5 = 305
Answer: 2
Step-by-step explanation:
add the 1 to the other 1 and it equals 2
Answer: 280
Step-by-step explanation:
??/500=7/100
7x500/100
35/500=7/100
35x8=280
I think this is the answer.
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:
