Answer:

See answer for Step 6 below.

Step 7: the slope is "-1/2" (negative 1/2)

Step-by-step explanation:

Step 6: A negative slope means that as the value of the coordinate "x" increases,the value of the coordinate "y" decreases, and the rate of change for points on the line is therefore negative. The line goes "DOWN" as you read the graph from left to right.

In order to calculate the slope, we can use the triangle defined by the points (0, 5), (4, 3)  and (0, 3) as shown in the attached image:

Where the "run" is from 0 to 4 , that is:  4 - 0 = 4

and the rise is negative (from 5 to 3: that is 3 - 5 = -2

Therefore, the rise over the run becomes: -2 / 4 = -1/2

The revenue from selling x units of a product at a price of p dollars per unit is given by xp, For a particular commodity, the r
marshall27 [118]

> Factor the expression for the revenue

We are given that the revenue is the product of price and number of units sold = x p. Given the equation of revenue we factor it:

R = 800 x – 0.25 x^2

Take out x from the equation:

R = x (800 – 0.25 x)

We see that this is now in the form x p

> Determine an expression for the price in terms of x

From the factored equation we can say that the price in terms of x is:

<span>p = 800 – 0.25 x</span>

If A and B are independent events, then it must be true that P(A|B)=P(A)?
nataly862011 [7]

Answer:

True : If A and B are independent events, then P(A|B)=P(A) is true.

Step-by-step explanation:

If A and B are independent, P(A and B) = P(A) * P(B)

P(A|B)    conditional probability, P(A) given B has already happened

= P(A and B) / P(B)

= P(A)*P(B) / P(B)

= P(A)  

Therefore

If A and B are independent events, P(A|B)=P(A) is true.
