-4x = -6 + 2x
-4x - 2x = -6
-6x/-6 = -6/-6
x = 1
hope this helps
Answer:
The answer to the system of equations is 4, -4
Answer: B.) $1,383.53
Step-by-step explanation:
Given: The total number bricks required to make the wall= 830
The speed of crew= 300 bricks/hour
Total hours they take to make the wall=
The cost of labour =$4,000 per eight-hour
⇒The cost of labour for 1 hour =
Now, the cost of wall=
Hence, B is the right answer, the cost of the new wall= $1383.53
There is only 1 number equal to 3 and that is 3.
Using binomial distribution where success is the appearing of any of the top 10 most common names, thus probability of success (p) is 9.6% = 0.096 and the probability of failure = 1 - 0.096 = 0.904. Number of trials is 11.
Binomial distribution probability is given by P(x) = nCx (p)^x (q)^(n - x)
Probability that none of the top 10 most common names appears is P(0) = 11C0 (0.096)^0 (0.904)^(11 - 0) = (0.904)^11 = 0.3295
Thus, the probability that at least one of the 10 most common names appear is 1 - 0.3295 = 0.6705
Therefore, I will be supprised that none of the names of the authors were among the 10 most common names given that the probability that at least one of the names appear is 67%.
