PLIS HEL The data shown in the table below represents the number of quarters Maria's aunt gives her every year for her birthday.

Age (in years) Number of quarters
2 32
6 47
7 51
4 40
5 43
3 38
8 60
1 23

Part A: Create a scatter plot to represent the data shown above. Sketch the line of best fit. Label at least three specific points on the graph that the line passes through. Also include the correct labels on the x-axis and y-axis.
Part B: Algebraically write the equation of the best fit line in slope-intercept form. Include all of your calculations in your final answer.
Part C: Use the equation for the line of best fit to approximate the number of quarters that Maria will be given when she turns 14 years old.

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Me asap! what is the slope of this line? enter your answer in the box.

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
