Answer:

-2

Step-by-step explanation:

The rate of change is the slope.

A slope that goes down to the right is negative. This line has a negative slope.

Now we will find the exact value of the slope.

slope = rise/run

rise = vertical distance (up is positive; down is negative)

run = horizontal distance (right is positive; left is negative)

Start at an easy-to-read point. Let's start at (0, 1) which is the y-intercept.

Now we need to go to another easy-to-read point. Let's use (1, -1) as our second point.

(By easy-to-read points, I mean points on grid line intersections whose coordinates can be read easily off the graph.)

We need to go from (0, 1) to (1, -1) by only moving vertically and horizontally. Start at (0, 1). We go vertically down 2 units and then horizontally right 1 unit to get to (1, -1). Going vertically down 2 units is a rise of -2. Going horizontally right 1 unit is a run of +1.

slope = rise/run = -2/1 = -2

slope = -2

The rate of change is the slope.

Answer: rate of change = -2

Assume that y varies inversely with x. If y = 7 when x = 2/3, find y when x = 7/3. <br>y = [?] ​
Alekssandra [29.7K]

Answer:

y = 2

Step-by-step explanation:

varies inversely

xy = k

y = 7 when x = 2/3

(2/3)7 = k

14/3 = k

k = 14/3

--------------------

find y when x = 7/3

(7/3)y = 14/3

multiply both sides by 3/7

y = 14/3 * 3/7

y = 2

Which method of separation can be used for a homogeneous mixture?
nignag [31]
One of the methods of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture. Heating the mixture, the component that has the lowest boiling point will evaporate and the separation can be done. the other method is called chromatography.so the answer is d.distillation! hope this helped!

A certain federal agency employs three consulting firms (A, B and C) with probabilities 0.4, 0.35 and 0.25 respectively. From pas
Marizza181 [45]

Answer:

(a) 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent.

Step-by-step explanation:

We are given that a certain federal agency employs three consulting firms (A, B and C) with probabilities 0.4, 0.35 and 0.25 respectively i.e.;

 P(A) = 0.4        P(B) = 0.35          P(C) = 0.25

Also, From past experience it is known that the probability of cost overruns for the firms are 0.05, 0.03, and 0.15, respectively which means;

Let CO = Event of cost overruns

P(CO/A) = 0.05 - It means probability of cost overruns given the consulting firm involved was A.

Similarly, P(CO/B) = 0.03      P(CO/C) = 0.15

(a) Probability that the consulting firm involved is company A given a cost overrun is experienced by the company is given by, P(A/CO);

We will use Bayes' theorem here calculating the above probability ;

           P(A/CO) = \frac{P(A)*P(CO/A)}{P(A)*P(CO/A) + P(B)*P(CO/B) + P(C)*P(CO/C)}

                          = \frac{0.4*0.05}{0.4*0.05 + 0.35*0.03 + 0.25*0.15} = 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent because the cost overruns happens only when the consulting firm is involved and also the cost overruns will differ as we move towards another consulting firm so the chances of cost overruns will depend on the fact that which consulting firm has been involved.
