A researcher wants to explore the relationship between two variables: Time 1 and Time 2.Time 1Time 2421400390383459436384362403392 Suppose Time 1 is the time (in seconds) that a beginning chess player takes to make their next move when presented with a particular chess configuration (Sea Cadet’s mate) before they receive special training on a variety of chess moves, including Sea Cadet’s mate. Time 2 is the time (in seconds) that the same player takes to make their next move when presented with the configuration for Sea Cadet’s mate after being trained to recognize and respond to that configuration. The researcher would like to test the effectiveness of the training by comparing the time needed to make a move before and after the specialized training session to see if there was a decrease in the time that the beginner chess players took to make the move. If we would like to test the effectiveness of the training, which of the following is the appropriate inference method to analyze these data?A. Inference for regressionB. Matched pairsC. Two independent samplesExpert Answer

factor trees are nice.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
