Rasek [7]3 years ago

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

The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Substitute the given parameters

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm

Carina spent a total of $5.27 buying a pineapple for $3.40 and several pounds of tomatoes that were on sale for $0.85 per pound.
gulaghasi [49]
Okay so I'm going to set up a equation:

5.27= 3.40+ 0.85x, we have our total our price of one pineapple and our variable

next I isolate the variable:

5.27-3.40=0.85x

next:

1.87=0.85x

x= 2.2

she bought 2.2 pounds of tomatoes

This Question is about Animals. I am no vegan, but why is it ok to eat certain animals such as fish and rabbit but not ok to eat
Zigmanuir [339]

Answer:

    From what I looked up on Google vegans don't eat fish, maybe some do but vegetarians do still eat fish. The reason why is because their are many types of health benefits that come with eating fish. "Seafood is a healthy source of protein, is full of heart healthy fats and contains iron and a host of vitamins like B-12" (Honeyager).

  I also feel like they ignore the fact that there food was a real animal cause some of society does not want to look at the thing there eating as a once alive animal cause I feel like they know how badly some animals are taken care of through there life time then kill through half of it. And yes I know that other livestock are taken well care of and given a good life before there death.  And most feel it's not okay to eat dogs is because most people actually live around them and know how sweet and kind they are and how they are pets for most. I also feel if it were cows (or some farm animal) instead, like people kept them as pets(just an example) then they would see the personality of a cow and I  guess they would feel more pity for them and not kill them. I hope you understand it's hard to explain my thinking pattern. IDK but this whole question and answer is just  based on peoples emotions whether they are saddened by it, say they don't care, or others who want to make a difference it's all built around peoples emotions and everyone's different and they have different emotions

The first paragraph I researched and the second is not fact at all, it just the true on how I feel. (It probably made no sense to you) Sorry for the 2 page essay!
