Answer:

-1/3

Step-by-step explanation:

Use the formula, (y2 - y1)/(x2 - x1).  In this case, there is a negative slope.  

Start from point, (1, 9) and go to point (4, 8).  

Use the formula:

(y2 - y1)/(x2 - x1)

Y2 = 8

Y1 = 4

X2 = 9

X1 = 1

(8 - 9)/(4 - 1) = -1/3

Therefore, the slope is -1/3

Answer:

-(1/3)

Step-by-step explanation:

777dan777 [17]

Answer:

20% probability that the next customer will pay with cash

Step-by-step explanation:

A probability, as a decimal, is the number of desired outcomes divided by the number of total outcomes.

To find as percent, we multiply by 100.

In this question:

Total of 54+63+153 = 270 customers.

Of those, 54 paid with cash.

Based on the number of customers from last week, what is the probability as a percent that the next customer will pay with cash?​

54/270 = 0.2

0.2*100 = 20%

20% probability that the next customer will pay with cash

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w
Marysya12 [62]
The main formula we use here is Work=Rate*Time,


1. The rate (speed of working) of Dominik is 

r_D=1project/8hours= \frac{1}{8}(prj/h)

2. Let the the rate of Katarina be r_K=x(prj/h)

Together they have a rate of r_D_K equal to \frac{1}{8}+x (project per hour)

so (\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)

simplify the units:

(\frac{1}{8}+x) *5=1

\frac{1}{8}+x = \frac{1}{5}

x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
