43 Pts IV. Calculate the slope of the trend line. (Choose two points on the line and find vertical change over horizontal change.)
Note: Graphing calculators and spread sheets have features with which to draw trend lines and determine the equation.
You may choose to use one of these options. If you use technology, indicate what steps were taken to arrive at your
equation.
V. Using the slope and y-intercept, write the equation of the trend line (y = mx + b).
VI. Choose a "calories from fat" value that is not in your collected data set and that is at least 10 fat calories away from any
collected value. Use the equation calculated in step V to predict the number of fat grams in an item having that number of
fat calories. Be sure to show your work.
VIL Search for an item in a fast food menu having the same number of fat calories as the one you chose above. (If you
cannot find the exact value, get as close as you can.) Compare the calculated value from step VI to this actual value.
Explain why (or why not) you would have expected your prediction (calculated value) to be close to the actual value.

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000

The price of a visit to the dentist is calculated according to the formula 50+100n50+100n where nn is the number of cavities the dentist finds. on your last visit to the dentist, 22 cavities were found. what was the cost of your visit?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
