the domain is the x value (first number) and the range is the y value (second number)

(if a number appears more than once in the domain or range, like in number 1 you don't have to write it again.)

to graph the domain and range you just plot the points,

and to map them you have to put the x values in the first oval and the y values in the second, usually in order from smallest to largest.

then you have to draw arrows connecting each x value to the y value that was in the same pair. just like when writing down the domain/range, if a number comes up again you don't have to write it down again. instead, you might have two or more arrows connecting to the same  number.

the sum of the measures of the three of a angles of triangle is 180. In a triangle, the measures of three angles are x,x-5 and x
Veseljchak [2.6K]

x + x-5 + x +23 = 180

 combine like terms:

3x +18 = 180

 subtract 18 from each side:

3x = 162

divide both sides by 3

x = 162 / 3 = 54

Angle x = 54 degrees

 Angle x-5 = 54-5 = 49 degrees

Angle x +23 = 54 +23 = 77 degrees

To support National Heart Week, the Heart Association plans to install a free blood pressure testing booth in El Con Mall for th
worty [1.4K]

Answer:

(a) Average number expected = 13.07 people

(b) Average number of persons = 14 persons

(c) Average amount of time = 0.9333 hours

(d) Time taken = 1 hour

Step-by-step explanation:

We are informed that the arrivals have a Poisson distribution from an infinite population. On average, 14 persons per hour request a test. Hence,

Arrival rate = λ = 14

Each blood pressure measurement takes 4 minutes. In 1 hour, 60 / 4 = 15 persons are served. Hence,

Service rate = μ = 15

(a) Average number in line = (λ^2) / μ(μ - λ)

                                             = (14^2) / 15(15 - 14)

                                             = 13.07

(b) Average number in system = λ / (μ - λ)

                                                   = 14 / (15 - 14)

                                                   = 14

(c) Average waiting time = Average number in line / λ

                                         = 13.07 / 14

                                         = 0.9333

(d) Average total time = Average number in system / λ

                                     = 14 / 14

                                     = 1

What is the length of the ladder? It's 6 ft. from the house at the bottom and touches the wall 14 ft. up at the top. Simplify yo
Sergio039 [100]

Base leg (b) = 6

Other leg (a) = 14

Hypotenuse (c) = c

plug this into the equation above and solve for c (taking the square root to solve)  so:

142 + 62 = c2

232 = c2

15.23 = c (feet)

Hope this helps have a good day. :)
