Answer:
12 m
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh . . . . . b represents the base; h represents the height
We are told that the height is 5 m less than the base, so we have ...
42 = (1/2)(b)(b -5)
84 = b(b-5) . . . . . . . . multiply by 2
We want two factors of 84 that differ by 5. The factors are ...
84 = 1·84 = 2·42 = 3·28 = 4·21 = 6·14 = 7·12
The relevant factors are 7 and 12, so now we know b-5 = 7 and b = 12.
The length of the base is 12 m.
Answer:
P=0.2613
Step-by-step explanation:
-Notice that this is a poison probability distribution problem.
-The Poisson probability function is expressed as:
where:
- x=0,1,2,3
- Euler's constant
- =mean number of occurrences.
Given that x= 2 and , the probability is calculated as:
Hence, the probability that in a randomly selected office hour, the number of student arrivals is 2 is 0.2613
So you're adding up .1, .002, and .000 003.
0.1 + 0.002 + 0.000003 = 0.102 003, or B.
