Find an ordered pair (x, y) that is a solution to the equation.<br><br> x-5y=5
timurjin [86]

Answer:

(x,y)=(0,-1)

Step-by-step explanation:

Observe that the equation x-5y=5 can be transformed in the equation of a line

x-5y=5\\-5y=5-x\\y=\frac{x-5}{5}\\y=\frac{1}{5}x-1

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that y=\frac{1}{5}*0-1=-1.

Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.

The waiting times on hold for a call to a customer service department are observed to have the following probability distributio
Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}

number of calls (x)           waiting time f(x) in minutes         f(x) *(x)

0                                                     0                                         0            

2                                                     3                                         6

4                                                     10                                       40

6                                                     15                                       90  

8                                                     10                                       80

10                                                     6                                       60  

\sum x = 30                                                                          \sum f(x) *x = 276

Therefore:

\sum (f(X)) = \dfrac{276}{30}

\sum (f(X)) = 9.2

Commission for every car he sells. The equation below gives Curtis' annual salary, S, in dollars after selling cars, C. Based on
pogonyaev

Answer:

$60,000

Step-by-step explanation:

Hi, to answer this question we have to analyze the function given:

S = 60,000 + 300C

Since 60,000 is a constant, it is Curtis’s base salary.

If doesn’t sell any car, he will only earn the amount of his base salary.

Mathematically speaking:

For C =0

S = 60,000 + 300(0)

S= 60,000

Feel free to ask for more if needed or if you did not understand something.
