a 25.0-kg boy stands 200 m from the center of a frictionless playground merry-go
round, which has a moment of inertia of 200. kgm. The boy begins to run in a circular path
with a speed of 0.600 m/s relative to the ground .a)Calculate the angular velocity of the merry-go-round
b)Calculate the speed of the boy relative to the surface of the merry -round

Because ecological disruption can put native species in contact with humans and livestock, it is believed that an increased number of threatened species in an area leads to a greater risk of novel disease transmission. A team of ecologists is investigating this relationship and records the number of threatened species and the number of novel diseases in different biogeographical regions. The following is their data set:

Region. Number of Threatened Species. Number of Novel Diseases.

1 12 20

2. 10 12

3 6 4

4 5 7

5 3 6

Mean 7.2 9.8

SD 3.7 6.4

a) Calculate the correlation between these two variables.

b) What are the slope and intercept for a linear regression model with number of diseases as the response variable?

c) Predict how many diseases we would expect for a region that has 10 threatened species?

d) Can we conclude from this data that ecological disruption causes an increase in the transmission of novel diseases? explain.

A second grade teacher has a 7-year old boy who has difficulty staying at his desk, in school. The boy came from a nuclear family of a mother, father and a little sister. He plays soccer on the weekends, in a community group, with his friends. The little boy has average grades, in school. He often gets out of his seat during classroom time to play with the class pet hamster and he wants to go outside to play, for recess. The boy often states that he will do his schoolwork later.

You are the second-grade teacher and you will use a behavioral theory to keep this second-grade boy in his seat during class time. Please utilize one of the following behavioral theorists, such as B.F. Skinner, Pavlov, or Watson, to change this boy’s classroom behavior

With respect to graphic functions and graphics programming, discuss the black box and the system it describes.

Graphic Tees is a design company that sells custom printed t-shirts. The firm sells printed t-shirts under a block pricing scheme that charges $16 per t-shirt if the customer buys up to 10 t-shirts and $13 if they buy 11 to 20 t-shirts. The demand curve is Q = 1200 - 50P, and the marginal cost of a t-shirt is $7. What are the profits for Graphic Tees under this block pricing scheme?
