Whenever you have a decision tree like this, the probability of reaching a specific leaf is the multiplication of the probabilities of each step you have to reach the leaf.

So, in order to reach the "hardcover and nonfiction" leaf, we have to take the "buys hardcover" branch (probability 0.35), and then the "buys nonfiction" branch (probability 0.55).

Given what we said above, the probability for "hardcover and nonfiction" is

0.35\cdot 0.55=0.1925

Answer:

b .  

Area=(x-5) (x-3)

Area =  x^2 -8x+15

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Area of a rectangle = width x length

The original length and width was x, so if the stage needs to be 5 feet narrower and 3 feet shorter.

x-5

x-5

The formula is:

A=(x-5) (x-3)

Solving:

A = (x.x) + (x.-3) + (-5.x)+ (-5.-3)

A = x^2 -3x -5x+15

A = x^2 -8x+15

What's The slope intercept form of: x - y = 7
Brilliant_brown [7]
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.
