Solve for b2: A=1/2h(b1+b2)
balandron [24]

Answer:

Step-by-step explanation:

A = \frac{1}{2}h(b_{1} + b_{2})

First let's multiply both sides by 2 to remove the \frac{1}{2} fraction:

2A = h(b_{1} + b_{2})

Next, let's divide both sides by h:

\frac{2A}{h} = b_{1} + b_{2}

Finally, let's subtract b_{1} from both sides:

b_{2} = \frac{2A}{h} - b_{1}

navik [9.2K]
Think About It: If You work 1 times as long, you are working the same amount of time. If you are working more than 1 times as much, you would be working more hours. 

3.5 x 1 = 3.5 
3.5 x 1.5 = 5.25 

So your answer is more

When dealing with the number of occurrences of an event over a specified interval of time or space and when the occurrence or no
jeyben [28]

Answer:

POISSON DISTRIBUTION

Step-by-step explanation:

When dealing with the number of occurrences of an event over a specified interval of time or space, the poisson distribution is often useful.

Poisson distribution is applicable if:

The probability of the occurrence of the event is the same for any two intervals of equal length.

The occurrence or nonoccurrence of the event in any interval is independent of the occurrence or nonoccurrence in any other interval.

The probability that two or more events will occur in an interval approaches zero as the interval becomes smaller.

Therefore, the appropriate probability distribution is POISSON PROBABILITY DISTRIBUTION.
