Explain how Hands on Learning is relevant to student learning and include a manipulative that can be used for teaching any type of math from grade k-8 with a hands on learning activity. Write about 300-500 words

4. For each scenario below, is the bolded probability distribution appropriate? Explain why or why not by considering the conditions for each probability distribution. You DO NOT need to calculate the probabilities. [3 marks] a. In a batch of computer chips, 8.4% are defective. 10 computer chips are randomly selected without replacement. The binomial distribution is used to calculate the probability that exactly 2 of the chips are defective. b. Between the hours of 2 and 4 PM on a Friday, the average number of phone calls per minute coming into the switch-board of a company is 2.5. The Poisson distribution is used to calculate probability that exactly 2 phone calls will arrive in one minute between 2 - 4 PM on Friday. c. 72% percent of cell phone users use their cell phones to access the Internet. A random sample of 10 cell phone users is selected with replacement . The binomial distribution is used to calculate the probability that at least 2 cell phone users use their phone to access the internet.

Here are the ways that four students thought about some subtraction facts. For each student, describe where each number in his or her thinking came from and why the strategy works. Then identify the basic fact strategy for subtraction being used by each of these students. (a) 14 - 9: Dale: "Nine and 1 more is 10, and then 4 more gets me to 14, so 1 and 4 is 5." (b) 15 - 7: Audrey: "I know that 7 and 7 is 14, and 1 more makes 15, so 1 plus 7 is 8." (c) 13 - 5: Jose: "First I took off 3 to get to 10, and then minus 2 more gets me to 8." (d) 15 - 8: Tamara: "I thought about how far it is from 8 to 15. It takes me 2 to get to 10, and then 5 more to get to 15, so 2 and 5 is 7."

I am having trouble with how to determine whether the relation is a function. I don't understand what would make it a function or not a function. I can see that the domain is increasing from -3 all the way to 10. But the range keeps throwing me off. The range jumps from -8 to 6 then to -5 so its confusing me. Online study sucks. Maybe you can explain better as to why it is a function or is not a function for me so I can better understand it. Thanks! {(-3, -8), (3, 6), (5, -5), (7, -6), (10, 6)}

Hello I need help with my homework questions for a Math and business MBA 501 course I am taking, I have attached a copy of the problems I am inquiring help with. Thanks

Johnson Filtration, Inc. provides maintenance service for water-filtration systems. Data that follow show the repair time in hours, the months since last service, the repair type and the repair person for a sample of 10 maintenance service calls. "Repair Time(hours)" "Months Since "Type of last service Repair" Repairperson 2.9 2 electrical Dave Newton 3.0 6 mechanical Dave Newton 4.8 8 electrical Bob Jones 1.8 3 mechanical Dave Newton 2.9 2 electrical Dave Newton 4.9 7 electrical Bob Jones 4.2 9 mechanical Bob Jones 4.8 8 mechanical Bob Jones 4.4 4 electrical Bob Jones 4.5 6 electrical Dave Newton 1. Ignore the months since last service and the repairperson data. Let type of repair be a dummy variable with 0 indicating a mechanical repair and 1 indicating an electrical repair. Develop the estimated simple linear regression equation that can be used to predict the repair time based on the type of repair (to 3 decimals). Time =______ +_______ Type

Let me tell you a little dirty secret about the mutual dislike between mathematicians and physicists. It can escalate into a full blown war if diplomacy is not attempted properly. It happens that a graduate student in theoretical/mathematical physics is looking for five members of his dissertation committee. He has been working closely with three professors in the mathematics department, and 5 professors in the physics department on his dissertation research. Now comes the monkey wrench. The mathematics department demands that the chair of the dissertation committee must be a mathematician in order to keep the physicists in check. What? How arrogant! But, there is no other choice if a dissertation committee has to be assembled in time. As usual, physicists have to swallow their pride in order to keep peace. Yes, they are just a bunch of you know what (click on the link ) in the mathematics department! For comic relief, can you figure out how may ways can this hapless graduate student choose among his beloved professors if the chair of the committee must be a mathematician, and the rest of the committee can be a mix of mathematicians and physicists? How do I find the answer or what is the answer to this problem? How can it be worked out

Blaise Pascal (1623-1662) did fundamental work in many areas of science and mathematics, including the physics of hydrostatics, the geometry of conic sections, and the foundations of probability and philosophy. He is also credited with inventing the first digital calculator. The following result is due to Pascal. Given ?ABC, construct a line DE, intersecting sides AB and AC at D,E, and parallel to BC. Pick any point F on BD and construct FE. Then, construct BG parallel to FE, intersecting side AC at G. Then, FC must be parallel to DG. Prove Pascal's Theorem. [Hint: Use the theorems in this section on parallels and similar triangles to show that AD = AF .] Hilbert [21, page 46] used Pascal's Theorem extensively to develop his "arithmetic of segments," by which he connected segment length with ordinary real numbers

Hi i am struggling with this question regarding mechanics of solids. Please help warm regards

Hi there, I am stuck with this problem for mechanics of solids. Please help. Thank you

Q. A woman is standing at the edge of a slow-moving river which is one mile wide, and she wishes to return to her campgound on the opposite side of the river. Assume that the woman can walk at 7 miles per hour and swim at 3 miles per hour, and that she will first swim to cross the river and then walk the remaining distance to the campground, which is 27 miles downstream from the point directly across the river from the woman's starting point. What route will take the least amount of time? See the diagram for the following: The woman's starting location is marked with a red 'X', her ending location is marked with a yellow star, and one of the possible routes for her is marked with a red solid line. The variable s denotes the distance (in mi) that she will swim, and the variable w denotes the distance (in mi) that she will walk, i.e., the distance between the red and blue arrows. Let x denote the distance (in mi) between the black and red arrows. Would you please help me to get answers (only red-highlighted one)

If you select 5 microprocessors from 100 microprocessors, where 30 of the 100 are defective, what is the probability that you select no defective processors?

The cost C for a company to produce, and the revenue R from the sale of x units of a very expensive computer microprocessor are given by: C = 15x + 105, R = 37.2x - 0.3x2 How many microprocessors should the company produce for the venture to break even (R = C)?
