please see attached the annotated solution

Given data

p=20%= 0.2

n=15 companies

let x = 5 the number of companies that outsource to overseas consultants

The binomial  probability distribution is given as

P(x=λ)=nCx*P^x*q^n-x

we also know that q=1-p

The sum of one third of a number and five is equal to six less than the number
abruzzese [7]

Call the number : x

(1/3)x + 5 = x-6

=> (1/3)x + 5 - (x-6) = 0
=> (1/3)x + 5 - x + 6 = 0
Group (1/3)x with -x, 5 with 6

=> [(1/3)x - x] + (5+6) = 0
=> (-2/3)x + 11 = 0
=> (-2/3)x = -11
=> x = -11 : (-2/3) = 33/2.

Recheck : 1/3 x 33/2 + 5 = 33/6 + 5 = 63/6 = 21/2

33/2 - 21/2 = 12/2 = 6 (21/2 is 6 less than 33/2, satisfied.)

Oksanka [162]

Answer:

The cost per print expressed as a slope is 7.125

Step-by-step explanation:

To calculate the cost per print, let’s envision that we have a graphical representation of cost of posters against the number of posters

We have the cost on the y-axis and the number of posters on the x axis

With the information given in the question, we shall be having two data points

Point 1 = (32,126)

point 2 = (48,240)

Now to find the slope of the line which is cost per print, we make use of both points in the slope equation.

Mathematically, slope m will be

m = y2-y1/x2-x1

Thus, we have;

m = (240-126)/(48-32)

m = 114/16

m = 7.125

The cost per print expressed as a slope is 7.125
