A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?
goldenfox [79]
To find the area of a trapezoid, we use the following formula:
a = \frac{1}{2} (b1 + b2) \times h
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
a = 150
b1 = 14
b2 = 16

Filling in the formula gives us:
150 = \frac{{1} }{2} \times (14 + 16) \times h
150 = \frac{1}{2} \times 30 \times h
150 = 15 \times h
Finally we have to divide both sides by 15.
h = 150 \div 15 = 10
Therefore, the height of the trapezoid is 10 meters.

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\%

8 is the median since its the number in the middle

8 is the mode since it is the repeated number

7 is the range since 12-5 is 7

all the numbers added and divided by the number of numbers is the mean

(5+6+7+8+8+10+12)/7=8
