Which two models would be most useful in predicting weather?
A. A mathematical model based on data
B. A plastic model of a cloud
C. A map that shows wind patterns
D. A peach used to represent Earth

Answers

Answer:

A. A mathematical model based on data

A mathematical model based on data and a map that shows wind patterns   would be most useful in predicting weather as it they will provide data with most accuracy.

What is accuracy?

Accuracy in terms of chemistry can be defined as to how close a measurement is to the true value.There are three types of accuracy:

1) Point accuracy-It means accuracy is present at that point of scale only.It does not give any information about the accuracy of the instrument.

2)Percentage of true value--It is the accuracy  which is determined by identifying accuracy of the instrument  and comparing it with the measured true value.

3)Percentage of scale range- It is the accuracy  which determines accuracy of the measurement.

Accuracy in case of instruments  is neglected up  to ±0.5 percent.

Answer in box is wrong Use the text of the opinion piece, "What's for Lunch," and your completed graphic organizer to answer the question below. Include evidence from the article to support your answer. Do you think this author has an agenda? If so, what is it? If not, what is the purpose of her article? Does she achieve her purpose? HERE IS THE WHATS FOR LUNCH ARTICLEWhats for Lunch?Marcia Amidon LustedZachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school instead of eating hot lunch. They couldnt understand why he didnt want to eat the gourmet food described on the schools online menu, which sounded both nutritious and interesting. Zachary just couldnt convince them that the food wasnt as great as it sounded. So in the fall of 2011, he began sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches were really like. Six months and 75 school lunches later, Zachary made a documentary film about his lunch called Yuck: A 4th Graders Short Documentary About School Lunch.Truth in Advertising?"The citys Department of Education says that its committed to providing delicious and nutritious meals through their food service program. But the lunch being served at my school was nothing like what they were advertising on their web site," Zachary, now 11, says in the documentarys trailer. "I told [my parents] thats not what they were actually serving me," he said. "But I dont think they believed me." For example, an "oven-baked pizza bagel with tricolor salad" was really nothing more than a slice of pizza and a wisp of lettuce. Sometimes there was no connection between the menu and what Zachary actually got. "Cheesy lasagna rolls with tomato basil sauce, roasted spinach with garlic and herbs" was, in reality, just a plastic-wrapped grilled cheese sandwich, all alone on a foam plate."When I came back home and showed them the footage, they were like, ugh!" Zachary said. His dad, an amateur filmmaker, started helping Zachary transform his video footage into a film. It won several awards, and Zachary also made appearances on television shows like Good Morning America.Not Perfect, But BetterLets face it: many times school lunches just arent going to taste as good as they sound. Students also complain that with lunches that follow the new school lunch guidelines, there just isnt enough food. Smaller portions, more fruits and veggies, and fewer calories leave some kids, especially teenagers, still hungry after eating their lunch. A group of students in Kansas even wrote a music video called "We Are Hungry," where they sing about their stomachs growling after lunch and how theyre collapsing on the sports field because they havent eaten enough.However, the new federal lunch guidelines do mandate meals that are better for students, with less sodium, more whole grains, fewer calories, and more fruits and vegetables, as well as skim or 1 percent milk. These are a definite improvement over school lunches of not that many years ago, which once stuck with fare like burgers, French fries, and chicken nuggets. Some schools even allowed fast food outlets like McDonalds and Pizza Hut to operate mini-restaurants in their cafeterias, or supply their products for students. Many schools have also reconsidered vending machines filled with sugary sodas, candy, and chips, replacing them with water and healthy snacks.The Lunch ForecastThe new school lunches are designed to help students eat better, and combat health problems like obesity in kids. Ideally, a healthy school lunch should also taste good ... or at least as good as the description on the menu. It should also keep students from taking a trip to the vending machine or a nearby convenience store as soon as lunch is over, because theyre still hungry. But will the lunches served in your cafeteria ever taste as good as a fast food burger or a gourmet meal cooked at home? You be the judge.
