You do 3 times 14 and you get 42

Well, the 3 is already included in the perimeter so you would do 14 - 3 = 11. Then you divide the 11 by 3 and get 3.66667, So the perimeter is 3, 3, 4, 4. Then you multiply 3 and 4 and get the area of 12.

What is the length of DC? 2 units 3 units 6 units 9 units

USPshnik [31]

Answer : Second Option is correct.

Explanation :

Since we have given in the figure ,

AE=12 units

AD=9 units

EB=4 units

DC=x units

By using the BPT theorem, which states that

"If a line is drawn parallel to one side of a triangle in distinct point , the other sides are divided in the same ratio."

So, here we have a ΔABC,

in which DE║BC as shown in the figure ,

so, by using the BPT we get,

$\frac{AE}{EB}=\frac{AD}{DC}\\\\\frac{9}{x}=\frac{12}{4}\\\\\frac{9}{x}=3\\\\x=3$

Hence, length of DC = 3 units .

The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Su

katrin [286]

Answer:

3.566%

Step-by-step explanation:

The probability formula for a poisson distribution is:

$P( k )=\frac{\lambda^{k}e^{-\lambda}}{k!} \\$

λ is the average of events

e is the euler's number

k is the number of events you want to know the probability

For this :

λ = 8.9 (on average the number of tickets is 8.9 per day)

k = 4 (you need to find the probability that exactly 4 tickets are written per day)

$P( k=4 )=\frac{8.9^{4}e^{-8.9}}{4!}=0,03566 =3.566\%$
